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.

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.

103. What is the Tiered architecture of u r instance?
Ans : Two Tier: Web and Forms on one node and Conc, admin and report on other node.
104. How to find formserver version?
Ans: f60gen and press enter, it will tell u the formserver version or we can find out from the frondend using help menu.
105. What is RRA?
Ans : RRA stands for Report Review Agent. RRA is nothing but FNDFS which is part of apps listener. RRA job is to pick the log/out file from the file system and show on the editor when u press view log/out button in ‘View concurrent request form’.
106. What is apps listener?
Ans : Apps lintener is the combination of FNDFS and FNDSM. FNDSM is service manager which will monitor application services on that node when GSM:enable profile value is ‘Y’.
107. What is GSM?

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.

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?

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 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:
