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 : 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.

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?

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.
SQL> select name from v$database@ TEST1_TO_TEST2;
NAME

---------

TEST2

SQL>select db_link from dba_db_links;

Ans : Error:
RC-50013: Fatal: Failed to instantiate driver/u01/fms2c/appfms2c/fms2cora/iAS/appsutil/driver/instconf.drvCauseThe source instance has files that adpreclone flags as 'autoconfigable' but in reality they are not. So adpreclone.pl adds these files into the instconf.drv. Then when adcfgclone.pl is run on target it looks for the template file to instantiate for these files and since there isn't a template file adcfgclone.pl fails. SolutionModify the target's instconf.drv and remove the offending lines. Then rerun adcfgclone.pl

178. What are the real time problems you have encountered and how you trouble shooted that?

Ans:1. Concurrent Program is erroing out with snapshot too old error. To resolve this we have added space to temp tablespace.2. Concurrent Program is erroing out with unable to extent a perticular tablespace by so and so extents. To resolve this we have added on more data file to that tablespace.3. When we are trying to start apache with adapcctl.sh script after a autoconfig run, its saying that “node id is not matching with the application server id”. To resolve this we have updated the server id column in fnd_nodes table with the server id value in dbc file.

PRVF-5436 : The NTP daemon running on one or more nodes lacks the slewing option "-x"

When I am Executing Cluster Verification utility I am facing below Error :


[oracle@dev147 bin]$ ./cluvfy stage -pre crsinst -n dev133,dev147 -fixup -verbose

Checking NTP daemon command line for slewing option "-x"
Check: NTP daemon command line
  Node Name                             Slewing Option Set?
  ------------------------------------  ------------------------
  dev147                                   no
  dev133                                   no
Result:
NTP daemon slewing option check failed on some nodes
PRVF-5436 : The NTP daemon running on one or more nodes lacks the slewing option "-x"
Result: Clock synchronization check using Network Time Protocol(NTP) failed

The solution was to re-configure the NTP server as follows:

Edit the /etc/sysconfig/ntpd configuration file and add the -x 

example :
Old Value

OPTIONS="-u ntp:ntp -p /var/run/ntpd.pid"

New Value :

OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"

The NTP server was then restarted as follows:

service ntpd restart


Result :

Starting Clock synchronization checks using Network Time Protocol(NTP)...

NTP Configuration file check started...
The NTP configuration file "/etc/ntp.conf" is available on all nodes
NTP Configuration file check passed

Checking daemon liveness...

  Node Name                             Running?
  ------------------------------------  ------------------------

  dev133                                yes
Result: Liveness check passed for "ntpd"

Step by Step to Create Oracle ASM Database on Linux 32bit&64bit

First We need to create Oralce ASM Disk Configuring Oracle ASM Disk

Install Oracle Database Software only












then create profile
export ORACLE_HOME=/oracle/product/10.2.0/db_1
export ORACLE_SID=MUT
export PATH=$PATH:$ORACLE_HOME/bin

open new Terminal type dbca



























Congrats Successfully Created the ASM Database .
