    1)What happens if the ICM goes down?


    All the other managers will keep working. ICM only takes care of the queue control requests, which means starting up and shutting down other concurrent managers.

    2)How will you speed up the patching process?


    You can merge multiple patches.
    You can create a response file for non-interactive patching.
    You can apply patches with options (nocompiledb, nomaintainmrc, nocompilejsp) and run these once after applying all the patches.


    3)How will you handle an error during patching?


    Look at the log of the failed worker, identify and rectify the error and restart the worker using adctrl utility.

    4)Provide a high-level overview of the cloning process and post-clone manual steps.


    Run pre-clone on the source (all tiers), duplicate the DB using RMAN (or restore the DB from a hot or cold backup), copy the file systems and then run post-clone on the target (all tiers).
    Manual steps (there can be many more):
    Change all non-site profile option values (RapidClone only changes site-level profile options).
    Modify workflow and concurrent manager tables.
    Change printers.

    5)Provide an introduction to AutoConfig. How does AutoConfig know which value from the XML file needs to be put in which file?


    AutoConfig uses a context file to maintain key configuration files. A context file is an XML file in the $APPL_TOP/admin directory and is the centralized repository.
    When you run AutoConfig it reads the XML files and creates all the AutoConfig managed configuration files.
    For each configuration file maintained by AutoConfig, there exists a template file which determines which values to pick from the XML file.


    6)Can you tell me a few tests you will do to troubleshoot self-service login problems? Which profile options and files will you check?


    Check guest user/password in the DBC file, profile option guest user/password, the DB.
    Check whether apache/jserv is up.
    Run IsItWorking, FND_WEB.PING, aoljtest, etc.

    7)What could be wrong if you are unable to view concurrent manager log and output files?


    Most likely the FNDFS listener is down. Look at the value of OUTFILE_NODE_NAME and LOGFILE_NODE_NAME in the FND_CONCURRENT_REQUESTS table. Look at the FND_NODES table. Look at the FNDFS_entry in tnsnames.ora.

    8)How will you change the location of concurrent manager log and output files?


    The location of log files is determined by parameter $APPLCSF/$APPLLOG and that of output files by $APPLCSF/$APPLOUT.

    9)If the user is experiencing performance issues, how will you go about finding the cause?


    Trace his session (with waits) and use tkprof to analyze the trace file.
    Take a statspack report and analyze it.
    O/s monitoring using top/iostat/sar/vmstat.
    Check for any network bottleneck by using basic tests like ping results.


    10)How will you change the apps password?


    Use FNDCPASS to change APPS password.
    Manually modify wdbsvr.app/cgiCMD.dat files.
    Change any DB links pointing from other instances.


    11)Provide the location of the DBC file and explain its significance and how applications know the name of the DBC file.



    Location: $FND_TOP/secure directory.
    Significance: Points to the DB server amongst other things.
    The application knows the name of the DBC file by using profile option "Applications Database Id."

Few Q&A
Posted on: 2010-11-16 22:11:56   By: akr14feb
 

1.) What's the diff. btw. 'adconfig.sh' and 'adautocfg.sh'

You will use script adautocfg.sh (on both Database & Application tier) which inturn will call adconfig.sh , which further will calladconfig.pl. You should not worry about later two scripts its for information only. adautoconfig.sh is script which you use to run autoconfig.


2.) Do I need to run autoconfig on both appl and db node after I change user applsys password.

yes, first on db tier and next on apps tier

3.) Must I stop all running application processes before I run autoconfig. i.e by running adstpall.sh?

Yes, if you are running autoconfig on application tier u need to stop the application tier, always database should be up

4.) Is it better to run adautocfg.sh on 11.5.10.2 rather that adconfig.sh.

Refer question 1, alway we run adautocfg.sh

1. How do we take care of customization while doing an upgrade.what kind of roadmaps do u give to client before upgrading.


2. Tell me few autoconfig issues which you have faced.

3. How do you recommend to your client for applying cpu patches.How to they impact the business.


4. Have you applied timezone patches. why do you apply how do they the affect the business if they are not applied

5. why apps and applsys should have same password. can't we have diff password for each.


6. In R12 multi node installation why all the node status( support_cp,support_forms etc ) is marked yes on all nodes in fnd_nodes table.-- is this represents the concept of unified appl top.


7. what is the use of cpu patches, what happens if we do not apply
these cpu patches.( i understand these are critical patch updates and
to resolve security vulnerabilities but can please explain me briefly
what do these actually meant for and how do they help in resolving
security issues with few examples)

8. what is the use of psu patches ( patch set updates, i understand
that both cpu and psu are db patches and both are released quaterly,
can you please throw some more light on it .

9.what is version conflict while patching and how to resolve it


10. How to answer this question in an interview " How many implementation
Projects are you involved / worked ". Is it better to say that i am
involved only in support or is it ok to say one or two implementation
projects. How long does an implementation project goes and what is the
process or procedure to start with and how to answer these questions
and what are involved.


11.Difference between 3460000 and 3480000 when both are used to upgrade
to 11.5.10.2

12.a. Actually the apps upgrade from 11.5.10 to 11.5.10.cu2 was
successful but when i checked the services the concurrent services
where not coming up. As usual i did a cmclean and later try to up the
cm it did not and later tried almost all options which were there in
metalink fnd_nodes.setup, updating node name in concurrent queues and
least running the autoconfig but no use.

13. we used the gsm profile and set it to N , the fndlibr process are
up but the target and source values are not same and log file show as
service started and ended

14. I thought to apply the latest autoconfig patch but the patch tells
me to upgrade to dev 6i, i thought it is of no issue to upgrade dev6i
if it is a conc mgr issue.

==============================

The Following are the few of Apps DBA 11i interview question, PLease watch this space for more question. These questions are intended to help newbee DBA to start their career as Oracle Apps DBA.

Please provide your comments on usefulness on the below Q & A.


1. How to determine Oracle Apps 11i Version ?
Ans : select RELEASE_NAME from fnd_product_groups;
You should see output like
RELEASE_NAME-----------------------11.5.10.2


2. How to find Database version ?
Ans :

SQL> select * from v$version;
The command returns the release information, such as the following:Oracle9i Enterprise Edition Release 9.2.0.7.0 - ProductionPL/SQL Release 9.2.0.7.0 - ProductionCORE 9.2.0.7.0 ProductionTNS for 32-bit Windows: Version 9.2.0.7.0 - ProductionNLSRTL Version 9.2.0.7.0 - Production


3. How to find opatch Version ?
Ans : opatch is utility to apply database patch , In order to find opatch version execute"$ORACLE_HOME/OPatch/opatch version"


4. How to find out invalid objects in the database
Ans : select count(*) from dba_objects where status ='INVALID'


5. How you will see hidden files in linux/solaris?
Ans : ls -la


6. How to find that the database is 64-bit/32-bit?
Ans : $RDBMS_ORACLE_HOME/bin/file oracle


7. What is top command?
Ans : top is a operating system command, it will display top 10 processes which are taking high cpu and memory. 8. What is a patch?Ans : A patch can be a solution for a bug/it can be a new feature.
9. What are the different types of patches?

Ans : oneoff, mini packs, family packs, maintanance packs, rollup pathches, colsolidated patches.


8. What is a oneoff patch?

Ans : An oneoff patch is a small patch of (20-90K size) without any pre-req’s


9. What is a mini pack ?

Ans : A mini pack is one which will upgrade any product patchset level to next level like AD.H to AD.I
10. What is Family pack ?

Ans : A Family pack is one which will upgade the patchset level of all the products in that family to perticular patchsetlevel.


11. What is Maintanance pack ?

Ans : A maintanance pack will upgrade applications from one version to another like 11.5.8 to 11.5.9
12. What is a Rollup patch?

Ans : A rollup patch is one which will deliver bug fixes identified after the release of any major application versions like 11.5.8/11.5.9


13. What is consilidated patch?

Ans: Consolidated patches will come into pictures after upgrades from one version of applications to anoter, all post upgrade patches will a consolidated and given as consolidated patch.


14. How u will find whether a patch is applied/not?

Ans : Query ad_bugs.
15. What is the other table where u can query what are the patches applied?

Ans : Ad_applied_patches


16. What is the difference between ad_bugs and ad_applied_patches?

Ans: A patch can deliver solution for more than one bug, so ad_applied_patches may not give u the perfect information as in case of ad_bugs.


17. How u apply a patch?

Ans : adpatch
18. What inputs you need to apply a patch other than driver name and etc?

Ans : apps and system passwords
19. What are the table u r adpatch will create and when?

Ans : Adpatch will create FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS table when it will apply d,g and u drivers


20. What is the significance of FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS table?Ans: FND_INSTALL_PROCESSES table will store the worker information like what job is assigned to which worker and its status. AD_DEFERRED_JOBS will come into picture when some worker is failed, it will be moved to AD_DEFERRED_JOBS table, from where again adpatch will take that job and try to resign, after doing this 3 times if still that worker is failing, then adpatch will stop patching and throw the error that perticular worker has failed. We need to trouble shoot and restrart the worker.


21. If it is a multinode installation which driver we need to apply on which node?

Ans: c,d,g on concurrent node and c, g on web node. If it is u-driver we need to apply on all nodes.


22.While applying a application patch is that necessary that u r database and listener should be up?

Ans: Yes . why because adpatch will connect to database and update so many tables etc…..


23. While applying a patch if that patch is failing because of a pre-req then how you will apply that pre-req patch and resume with the current patch?


Ans: We need to take the backup of FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS tables and restart directory at APPL_TOP/amdin/SID and then use adctrl to quit all the workers. Then apply the pre-req patch , after that rename u r restart directory to its original name and create FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS tables from the bcakup tables. Start adpatch session and take the options want to continue previous session.


24. What is adctrl?
Ans: Adctrl is one of the adutilities, which is used to check the status of workers and to manage the workers.


25. Can u name some of the menu options in adctrl?
Ans: Check the status of workers, tell manager that worker has quited, restart a failed worker etc….


26. How to skip a worker and why?


Ans: We can skip a worker using option 8 in adctrl which is hidden. We will go for skipping a worker when we have executed the job which the worker is supposed to do.


27. How adpatch knows what are the pre-req’s for the patch which it is applying?


Ans: With every patch a file called b.ldt file will be delivered which contain the pre-req information. adpatch load this into databse using FNDLOAD and check , whether those pre-req patches were applied or not.


28. What is FNDLOAD ?
Ans: FNDLOAD is a utility which is similar to sqlloder but loads code objects into database, where as SQLLOADER loads data objects into database.


29. What c-driver will do?
Ans:

C-drive copies the files from patch unzipped directory to required location in u r application file system. Before copying it will check the file version of the existing file at the file system with the file version of the file in the patch. If the patch file version is higher than what it is at file system level then only c-driver will copy that files.


30. How adpatch will know the file versions of the patch delivered files?
Ans:

With each patch a file with name f.ldt is delivered , which contain the file versions of the files dilivered with the patch. Adpatch will use this file to compare the file versions of files its delivering with the file on file system.


31. What is the adpatch log file location?
Ans : APPL_TOP/admin/SID/log


32. What is the worker log file name and its location?
Ans : adwork01,adwork02…… and location is APPL_TOP/admin/SID/log


33. How u will know what are the files the patch is going to change just my unzipping the patch?
Ans:

When u unzip a patch it will keep all the files related to a particular product under that directory inside u r patch directory for example if the patch delivering files related to FND product then it will create a sub directory under the patch directory with the name FND in which it will put all related files to that product


34. What is the significance of backup directory under u r patch directory?
Ans:

When we apply a patch it will keep the copy of the files which its going to change in file system.


35. What are the different modes you can run your adpatch?
Ans :

1.Interactive – default mode

2.Non interactive – Use defaults files to store prompt values

(adpatch defaultsfile= interactive=no)

3. Test – Without actually applying a patch just to check what doing.(adpatch apply=no)

4. Pre-install – (adpatch preinstall=y)

This mode will be usefull to discrease upgrade downtime as its applies bus fixes without running SQL,EXEC and generate portion of patch.

36. How u will monitor u r applications as well as database?
Ans:

We have our custom scripts which is sheduled to run at a specific time which will monitor whether applications and databases are up/not. And it will mail us if some processes is not running. And we have one script which will check database alert log for ORA errors and mails it to us . Based on this we will react.


37. What are the latest ORA errors u have encountered?
Ans:

Useually we will get the ORA errors like unable to extend the tablespace by so and so size. And we will check those tablespaces for space, if space is not there we will resize the datafile and add one more datafile.


38. Which table u will query to check the tablespace space issues?
Ans : bytes column in dba_free_spaces and dba_data_files


39. Which table u will query to check the temp tablespace space issues?
Ans : dba_temp_files


40. What is temp tablespace? And what is the size of temp tablespace in u r instances?
Ans : Temp tablespace is used by so many application programs for sorting and other stuff. Its size is between 3 to 10 GB.

42. What are the parameter autoconfig will ask for?
Ans : Context file name and apps password


43. What is context file?
Ans : Context file is a central repositary, which stores all application configuration information. The name is like _ .xml

44. How you will find autoconfig is enabled/not for u r applications?
Ans: 1. Open any env / configuration files, the first few lines will tell u that this files are maintained by autoconfig.2. If contextname.xml file is there in APPL_TOP/admin


45. How autoconfig will create env and configuration files?
Ans: Autoconfig will go to each and every top template directory take the templates from there and fill the values from xml file and create the required files.


46. In how many phases autoconfig will run?
Ans : Autoconfig will run in 3 phases.

1.INIT – Instantiate the drivers and templates

2.SETUP – Fill the templated with values from xml and create files

49. How to run autoconfig in test mode?
Ans :

adchkcfg.sh script at AD_TOP/bin. This script will run autoconfig in test mode and create the difference file which tells us what is going to change , when u actually run autoconfig.


50. How to find autoconfig is enabled or not for database?
Ans:

If we have appsutil directory under RDBMS_ORACLE_HOME

112. How to find operating system version?
Ans : uname –a


113. What are the problems u have faced while shutting down applications?


Ans : While shutting down application generally concurrent manager won’t go down because some or the other request may be running. We will see what are the concurrent requests running by querying fnd_concurrent_requests, fnd_concurrent_program_vl, v$session,v$process and v$sqltext. If that request is only doing some select statement then we will kill those requests, otherwise we will check what time it will take to complete by querying the previous runs of that request and then we will decide what to do.


114. What are the problems u have faced while starting up applications?
Ans : Most of the time we will encounter problem with starting up concurrent managers. Reasons , database listener may be down or FNDSM entries are wrong in tnsnames.ora of 806_ORACLE_HOME.


115. How to find the locks and what is the resolution?
Ans : we can find general locks with the following query:

select * from sys.dba_dml_locks order by session_id.

We can find the dead locks with the following query:

select * from v$lock where lmode > 0 and id1 in (select distinct id1 from v$lock where request > 0)
If it’s a dead lock, we need to kill that session.


116. How to kill a database session?
Ans : alter system kill session '&sid,&sno';


117. How to find adconfig is enabled for oracle operating system user/database?
Ans : If appsutil directory is there in RDBMS_ORACLE_HOME


118. Which files tell u the database helath?
Ans : alert log file @RDBMS_ORACLE_HOME/admin//bdump


119. How to apply a rdbms patch?
Ans : Using opatch


120. How to find opatch is enabled or not for u r database?
Ans : If Opatch directory exists under RDBMS_ORACLE_HOME.


121. What is the pre-req for applying a rdbms patch?
Ans : Inventory should be set in file oraInst.loc @/var/opt/oracle or /etc


122. What is Inventroy?


Ans: The oraInventory is the location for the OUI (Oracle Universal Installer)'s bookkeeping. The inventory stores information about: All Oracle software products installed in all ORACLE_HOMES on a machine Other non-Oracle products, such as the Java Runtime Environment (JRE)


In a 11i Application system the RDBMS and iAS ORACLE_HOMEs are registered in the oraInventory. The 806 ORACLE_HOME, which is not managed through OUI, is not.


123. What are different types of inventories?
Ans:

The Global inventory (or Central inventory) The Local inventory (or Home inventory)


124. What is Global inventory?


Ans : The Global Inventory is the part of the XML inventory that contains the high level list of all oracle products installed on a machine. There should therefore be only one per machine. Its location is defined by the content of oraInst.loc.The Global Inventory records the physical location of Oracle products installed on the machine, such as ORACLE_HOMES (RDBMS and IAS) or JRE. It does not have any information about the detail of patches applied to each ORACLE_HOMEs.The Global Inventory gets updated every time you install or de-install an ORACLE_HOME on the machine, be it through OUI Installer, Rapid Install, or Rapid Clone.
Note: If you need to delete an ORACLE_HOME, you should always do it through the OUI de-installer in order to keep the Global Inventory synchronized.


125. What is local inventory?


Ans : There is one Local Inventory per ORACLE_HOME. It is physically located inside the ORACLE_HOME at $ORACLE_HOME/inventory and contains the detail of the patch level for that ORACLE_HOME.The Local Inventory gets updated whenever a patch is applied to the ORACLE_HOME, using OUI.


126. What is rapid clone?
Ans : Rapid Clone is the new cloning utility introduced in Release 11.5.8. Rapid Clone leverages the new installation and configuration technology utilized by Rapid Install


127. How do I determine if my system is rapid clone enabled?
Ans : First, verify that your system is AutoConfig enabled. Then, verify that you have applied the latest Rapid Clone patch.


128. Explain the cloning process?

Ans :
1. Run adpreclone as applmgr and oracle user on source Perl adpreclone.pl dbTier as oracle user Perl adpreclone.pl appsTier as applmgr user

2. Take the cold/hotbackup of source database

3. Copy the five directories appl,comn,ora , db,data to target

4. Rename the directories, and change the permisssion

5. Set the inventory in oraInst.loc

6. Run perl adcfgclone.pl dbTier as oracle user,if the backup type is cold

7. If the backup type is hotbackup then Perl adcfgclone.pl dbTechStack. Create the control file on target from the control script trace file from source Recover the database Alter database open resetlogs

8. Run autoconfig with the ports changed as per requirement in xml.

9. Run perl adcfgclone.pl appsTier as applmgr

10. Run autoconfig with the ports changed as per requirement in xml.


129. What is the location of adpreclone.pl for oracle user?
Ans : RDBMS_ORACLE_HOME/appsutil/scripts/


130. What is the location of adpreclone.pl for applmgr user?
Ans : $COMMON_TOP/admin/scripts/


131. What is the location of adcfgclone.pl for oracle user?
Ans : $RDBMS_ORACLE_HOME/appsutil/clone/bin


132. What is the location of adcfgclone.pl for applmgr user?
Ans : $COMMON_TOP/clone/bin


133. What is statspack?
Ans : Statspack is a database utility to gather database and session level performance information.


134. How to install statspack?
Ans : Run the script spcreate.sql @RDBMS_ORACLE_HOME/rdbms/admin
Note more details on statspack refer metalink noteid: 149113.1


135. How to enable trace at database level?
Ans : set init.ora parameter sql_trace


136. How to enable trace for a session?
Ans: Alter system set sql_trace=true;

Execute the sql query

Alter system set sql_trace=false;

This will create a trace file at

$RDBMS_ORACLE_HOME/admin/contextname/udump with the spid of the current sql session.


137. How to enable trace for other session?
Ans : exec sys.dbms_system.set_sql_trace_in_session(sid,serial#,true/false)
Eg: To enable trace for sql session with sid 8SQL> exec sys.dbms_system.set_sql_trace_in_session(8,121,true);

PL/SQL procedure successfully completed.
To disable trace

SQL> exec sys.dbms_system.set_sql_trace_in_session(8,121,false);


138.What is the location of inint.ora ?
Ans : $RDBMS_ORACLE_HOME/dbs
139. What is that trace files contains and the utiliy used to read them?


Ans : Trace file contains the detail diagnostics of a sql statement like explain plan, physical reads, logical reads, buffer gets etc. Tkprof utility is used to convert trace file into readable format.


140. What is the syntax for tkprof?
Ans: tkprof explain=apps/ sys=no


141.How do we find adpreclone is run in source or not ?
Ans : If clone directory exists under RDBMS_ORACLE_HOME/appsutil for oracle user and $COMMON_TOP for applmgr user.


143. How to find trace file for a given concurrent request id?
Ans : Go to $RDBMS_ORACLE_HOME/admin//udump

grep “ “ *


144. What is a database link? How to create it?

Ans : If we want to access objects of another database from this database then we need a database link from this database to the other.
1.Login as oracle user

2.sqlplus “/as sysdba”

3. create database link connect to identified by using '';
Ex
SQL> create database link TEST1_TO_TEST2 connect to apps identified by apps using 'TEST2';
Database link created.

Q)What is your day to day activity as an Apps DBA?
Ans:
As an Apps DBA we monitor the system for different alerts (Entreprise Manager or third party tools used for configuring the Alerts) Tablespace Issues, CPU consuption
Database blocking sessions..etc
Regular maintanance activies like cloning,patching,custom code migrations (provided by developers)
Working with user isses.

Q)How often Do you patch?
Ans: Usually for non-production the patching request comes aroung weekly 4-6 and the same patches will be applied to Production in the outage or maintanance window.
Production has weekly maintance window (Eg Sat 6PM to 9PM) where all the changes (patches) will applied on production.

Q)How often Do you clone?
Ans: Cloning happens biweekly or monthly depending on the organization requierement.

Q)What change control/management or CCB?
Ans: Every organization has change control process, Change control process is no change goes into production witout proir testing on non-production instance.
Eg: If a user encouters an issue in production instance and the fix for the issue is known, Still the fix should not be applied directly on production, as it is not tested.
The same fix need to be first applied on a non-prod instance where the similar issue is happening and test the issue and instance stability.
Once user is happy with the results the change or fix will be implemented to production with the approval from Change control Board, CCB is a managemant team who reviews all the changes being deployed to production,
Depending on the need and criticality and testing results they approve the change movement to production instance.

Q)How much time does it take to upgrade, clone ?
Ans: Clone usually takes around 48hrs to copy and configure and upgrade depends on the database size and module involved.
upgrade from 11.5.9 to 11.5.10.2 will take around 3-4 days and 11i to R12 upgrade will take around 4-5 days.

Q)What is the meaning QA,CRP,SIT,DEV,UAT,PRE-PROD,PROD Instance?
QA - Tesing Instance
CRP - Conference Room Pilot
SIT - System Integration Testing
DEV - Developement
UAT- User Acceptence Testing
STAGE - Pre-production Instance
Prod - Production/actuall instance where the business is running

Q)What do we have in FND_NODES?Ans:
FND_NODES table contains information about node_names and services enabled on a node.
In multinode instance if you want to know which node is running what services, You can query the fnd_nodes and get that information.

Q)when do we run FND_CONC_CLONE.SETUP_CLEAN ?
Ans:
FND_NODES table contains node information, If you have cloned test instance from production still the node information of production will be present after clone in the test instance.
we use FND_CONC_CLONE.SETUP_CLEAN to cleanup FND_NODES table in the target to clear source node information as part of cloning.
Below syntax to execute:
SQL> sho user
USER is "APPS"
SQL> EXEC FND_CONC_CLONE.SETUP_CLEAN;
PL/SQL procedure successfully completed.
SQL> commit;
Commit complete.

This will delete all the entries in the fnd_nodes table, to populate it with target system node information, Run autoconfig on DB node and Applications node.

Q)How verify the sysadmin password from command line?
Ans:
This utility can be used to verify the GUEST/ORACLE password
SQL>select fnd_web_sec.validate_login('SYSADMIN','')from dual;
If it returns Y then sysadmin password is correct
If it returns N then sysadmin password that we are using
Eg:
SQL> select fnd_web_sec.validate_login('SYSADMIN','SYSADMIN123') from dual;
FND_WEB_SEC.VALIDATE_LOGIN('SYSADMIN','SYSADMIN123')
--------------------------------------------------------------------------------
N
SQL> select fnd_web_sec.validate_login('SYSADMIN','SYSADMIN') from dual;
