How to migrate PUTTY settings from one windows desktop/laptop to the other?
Migrating putty settings from one desktop/laptop to the other box comes in handy when you had already customized your putty with saved sessions. The migration will also help a new member of an exisitng DBA support team.
Here are the steps
Start -> Run (or Windows Button + R)
Type in ‘regedit’ and press enter – this command will open the registry editor window
Go to HKEY_CURRENT_USER -> Software -> SimonTatham
Right Click on SimonTatham and select Export
Provide a file name and save the file.
Copy and execute the exported file on the new box – voila .. you are all set with the putty on the new box.
Note: this will only bring the putty configurations and NOT the putty executable itself.

dbca – Creating RAC Database using dbca in silent mode
During the course of the DBA life, we all know how irritating it is to create a DB or to install a Oracle Software on a UNIX Flavour box from a remote machine using a X – Server. Each click would take minutes to react (My favourite is the tab button on the keyboard) but still at-times we have to make use of the mouse. Anyways, recently we installed 10203 on a HP server which already has cluster setup. Everything went good in terms of 10201 installation, 10203 upgrade (both binaries) and even dbca 14 screens. But nothing happened when clicked on the finish button in dbca (14th screen). No useful information in the log files. I pressed cancel and re-launched it again and did the dbca exercise all the way till the end, still no luck. By this time my patience level was minus 25. It is at this stage i thought how about creating the database in silent mode and you know what, creating the DB in silent mode is 200 times faster than the GUI and the db creation completed in less than 5 minutes.
Syntax to create a General Purpose RAC Database on a Cluster File System.
dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbName opitstop -sid opitstop -sysPassword opitstop123 -systemPassword opitstop123 -emConfiguration NONE -datafileDestination /opt/oracle/oradata/opitstop -storageType CFS -nodelist RAC_NODE_1,RAC_NODE_2 -characterSet WE8IS08859P15 -listeners opitstop -memoryPercentage 30 -continueOnNonFatalErrors true
Place above command in a .sh file (shell script) say createRACDB.sh and just run it. Before running the script make sure the cluster services (crs) are running and also you have user equivelance between the rac nodes for the oracle owner ie., eg. if the oracle owner username is oraracdb in RAC_NODE_1 and RAC_NODE_2 then when you do a ssh from RAC_NODE_1 to RAC_NODE_2 it should go without asking for the password.
There are more options available with dbca. Some of them are -createDatabase, -createTemplateFromDB, -createCloneTemplate, -generateScripts, -deleteDatabase, -configureASM, -deleteInstance. For a complete list of the usage execute dbca -help.
DBCA Log Location: $ORACLE_HOME/cfgtoollogs/dbca/[SID]
Happy DB creation(s) !!!

Interesting enhancements in 12.0.6 – R12.ATG_PF.A.DELTA.6
Oracle Applications Technology Stack Release Update Pack 6 (R12.ATG_PF.A.DELTA.6)
Autoconfig has two new options
1. Parallel Mode
2. Profile Mode
Parallel Mode
This mode enables autoconfig to be executed parallel across all mid-tiers. Oh man, i love this feature … it really helps when you have multiple mid-tiers.
Just add -parallel to your normal adconfig command
Profile Mode
This option provides a drill down HTML report of the autoconfig run.
Just add -profile to your normal adconfig command
For more information on above options refer to Metalink Note 742110.1

There could be many root causes for this error. If you look closely into the errorstack, it complains about null connection.
Caused by:
oracle.apps.jtf.base.resources.FrameworkException:
Error in IAS Cache:
java.lang.NullPointerException:
null Connection
Every access to the login page (http://machine.domain.com:port/OA_HTML/AppsLogin) (in R12) establishes a connection to the database as GUEST user using the DBC file. (In 11i, the url page is a static html which doesnt establish a connection)
If the mid-tier gets a connection, it displays the login page else it throws “oracle.apps.fnd.cache.CacheException”.
Now lets look at some possible reasons for not getting a connection.
1. Database is down
2. Database is up but the listener is down.
3. Archive Location is full, which prevents new connections till freed-up.
4. The instance was recently cloned and the GUEST user password is not in sync.
When the instance is cloned from source, there is a remote chance that the guest user password is not in sync. By sync, i mean the profile option value and the dbc file value for guest user password.
Steps to verify the values (perform below steps in the mid-tier)
4.1 DBC File value
$ grep -i GUEST_USER_PWD $FND_SECURE/[SID].dbc
GUEST_USER_PWD=GUEST/GUEST
4.2 Profile Option Value
sqlplus apps/[apps_pwd]
select fnd_profile.value(‘GUEST_USER_PWD’) from dual;
FND_PROFILE.VALUE(‘GUEST_USER_PWD’)
——————————————————————————–
GUEST/GUEST
Values from 4.1 and 4.2 should be in sync and in our case it is. Now lets connect to the database using the guest password.
4.3 GUEST User Connectivity Check
sqlplus apps/[apps_pwd]
select FND_WEB_SEC.VALIDATE_LOGIN(‘GUEST’,’GUEST’) from dual;
FND_WEB_SEC.VALIDATE_LOGIN(‘GUEST’,’GUEST’)
——————————————————————————–
Y
5. Ok, i didnt do a clone and the GUEST user password is in sync. What next.
The next possible reason, the database is not allowing any new sessions. May be the maximum number of sessions defined at the database level had already reached.
If you had followed all the steps sequentially as defined above, you would have realised that database does accept new connections, since you were able to verify the GUEST user password profile option value. If SESSIONS parameter value had been reached you would have got the error ORA-00018: maximum number of sessions exceeded.
6. Now what, my database is accepting new sessions.
Next option is to look for stale database connections.
ps -fu [oracle_user] | grep -i ‘LOCAL=NO’
This command will give you a list of stale connections. Use below command to kill them and to free up resources.
CAUTION: BELOW COMMAND WILL KILL THE CONNECTIONS
ps -fu [oracle_user] | grep -i ‘LOCAL=NO’ | grep -v grep | awk ‘{print “kill -9 “$2}’ | ksh
Hope one of the above mentioned steps resolves your issue when you encounter “Unable to generate forwarding URL. Exception: oracle.apps.fnd.cache.CacheException”

How to enable trace with BIND variables and WAITs for a concurrent program?
In this link, we had mentioned about tracing a concurrent program, but the drawback of this method is it doesnt yield information about the BIND variable values. So in this post we will talk about it.
Scenario
X submitted a concurrent request and its running for a long time and never completes. X approached you to see what is the problem with the concurrent request.
Steps
1. Inform X to logout from his ERP session.
2. Login as sysadmin user
3. System Administrator -> Profile (System)
4. Values: User = X, Profile = Initialization SQL Statement – Custom (you can also mention Initialization%Custom)
5. Under user field enter the following
begin fnd_ctl.fnd_sess_ctl(”,”,’TRUE’,’TRUE’,’LOG’,’ALTER SESSION SET EVENTS=”10046 TRACE NAME CONTEXT FOREVER, LEVEL 12” TRACEFILE_IDENTIFIER=”[ANY_IDENTIFIER]”‘);end;
[ANY_IDENTIFIER] = Any value to identify the trace file.
LEVEL 12 – Both Binds and Waits
LEVEL 8 – Only WAITS
LEVEL 4 – Only BIND Variables
All above levels will include the sql statements being executed and not only the binds and waits.
6. If tracing had been enabled at the concurrent program level as mentioned in this link, please disable it by removing the check box. [IMPORTANT]. If you have trace enabled for the concurrent program, then it will take precedence for the profile option.
7. Kill / cancel the long running concurrent request (if its still running)
8. Request X to login to ERP and instruct X to submit the concurrent request again and logout. Nothing else. This will ensure we capture the trace information specific to the concurrent request and not for other actions.
At this stage, you will find a trace file generated at $ORACLE_HOME/admin/SID_Hostname/udump with [ANY_IDENTIFIER] as part of it.
Inside the trace file you will be able to see information about the bind variable values being passed to and used by the concurrent program.
Eg:
Bind#0
oacdty=12 mxl=07(07) mxlc=00 mal=00 scl=00 pre=00
oacflg=13 fl2=206001 frm=00 csi=00 siz=8 off=0
kxsbbbfp=9fffffffbf2e88d8 bln=07 avl=07 flg=09
value=”[BIND VARIABLE VALUE]”
Bind#1
oacdty=12 mxl=07(07) mxlc=00 mal=00 scl=00 pre=00
oacflg=13 fl2=206001 frm=00 csi=00 siz=8 off=0
kxsbbbfp=9fffffffbf2e88f8 bln=07 avl=07 flg=09
value=”[BIND VARIABLE VALUE]”
Note: Make sure you remove the profile option value for X after the job is done, else every action of X will generate a trace file in udump directory.
Happy Trouble shooting.

How to clear cache for a specific component in R12?
As we all know the normal tendency for clearing cache in Oracle Apps is to delete the $COMMON_TOP/_pages directory. In 11i, after deleting we dont have to recompile the jsps but in R12 we have to recompile the pages since s_jsp_main_mode is set to justrun by default which is in turn updated in orion-web.xml. Click here for more info.
Ok coming to this post, how can i clear cache for a specific component of Oracle Apps R12 viz., iprocurement, istore etc., Is this even possible ? Yes it is and this option comes handy when somebody modifies a jsp page which is part of say istore, then it makes sense to clear cache for istore and not for the whole server.
Clearing cache for specific Component/Application in R12
Login as sysadmin
Select “Functional Administrator” responsibility
Go to Core Services ==> Caching Framework ==> Tuning
Query the application (for example iStore) or by Name or code.
Select the component and clear the cache.
Note: For some specific configuration changes, we need to bounce Apache also.
Clearing Global Cache in R12
a) Go to Functional Administrator Responsibility
b) Go to Core Services ==> Caching Framework
c) Go to Global configuration and clear all the cache from there.(Only If you want to clear all the cache)
Hope this helps…..
Thanks,
Sam.

While trying to apply a patch or listing inventory, using opatch utility (be it on the Database node or for the Applications Tech Stack) below error is encountered:
—————————————————————————
LsInventory: OPatch Exception while accessing O2O
OPATCH_JAVA_ERROR : An exception of type “OPatchException” has occurred:
OPatch Exception:
OUI found no such ORACLE_HOME set in the environment
Can not get details for given Oracle Home
An exception occurs
null
There is no Interim Patch
OPATCH_JAVA_ERROR : An exception of type “OPatchException” has occurred:
Can not get a list of inventory on this home.
ERROR: OPatch failed because of Inventory problem.
—————————————————————————
Scenario
Imagine you are trying to apply a patch to 10.1.3 Tech Stack Oracle Home on R12.
What did i do wrong ?
1. Did i source the corrent environment file ?
Yes, i did, my echo $ORACLE_HOME command points to 10.1.3 home instead of the default 10.1.2 home. hmmm ok
2. Am i using the correct opatch utility?
yes, which opatch is pointing to $ORACLE_HOME(10.1.3)/Opatch/opatch
3. Is the inventory location accessible ?
Yes, oraInst.loc under Oracle Home (10.1.3) is pointing to a valid directory.
$ cat oraInst.loc
inventory_loc=/var/opt/oracle/oraInventory
4. Does the inventory has information about the Oracle Home you are trying to patch?
How do i check that ….
$ cd /var/opt/oracle/oraInventory
$ ls -latr
total 112
drwxrwxr-x 3 username dba ..
drwxrwxr-x 2 username dba oui
-rwxrwxr-x 1 username dba sessionContext.ser
drwxrwxr-x 2 username dba ContentsXML
-rwxrwxr-x 1 username dba oraInstaller.properties
drwxrwxr-x 2 username dba Contents
drwxrwx— 3 username dba logs
-rwxrwxr-x 1 username dba install.platform
drwxrwxr-x 6 username dba .
$ cd ContentsXML
$ vi inventory.xml
<INVENTORY>
<VERSION_INFO>
<SAVED_WITH>10.1.0.5.0</SAVED_WITH>
<MINIMUM_VER>2.1.0.6.0</MINIMUM_VER>
</VERSION_INFO>
<HOME_LIST>
<HOME NAME=”SID_TOOLS__masked_oracle_home_tech_st_10_1_2″ LOC=”[masked_oracle_home]/tech_st/10.1.2″ TYPE=”O” IDX=”1″/>
</HOME_LIST>
</INVENTORY>
[[[[DO YOU SEE AN ENTRY FOR THIS ORACLE HOME (10.1.3)]]]]
ooops … i dont …. THIS IS THE ISSUE
So what should i do now?
Pretty simple, add an entry for this Oracle Home just above or below HOME_LIST tag.
<HOME NAME=”SID_TOOLS__masked_oracle_home_tech_st_10_1_3″ LOC=”[masked_oracle_home]/tech_st/10.1.3″ TYPE=”O” IDX=”2″/>
After making changes,
<INVENTORY>
<VERSION_INFO>
<SAVED_WITH>10.1.0.5.0</SAVED_WITH>
<MINIMUM_VER>2.1.0.6.0</MINIMUM_VER>
</VERSION_INFO>
<HOME_LIST>
<HOME NAME=”SID_TOOLS__masked_oracle_home_tech_st_10_1_2″ LOC=”[masked_oracle_home]/tech_st/10.1.2″ TYPE=”O” IDX=”1″/>
<HOME NAME=”SID_WEBOH__masked_oracle_home_tech_st_10_1_3″ LOC=”[masked_oracle_home]/tech_st/10.1.3″ TYPE=”O” IDX=”2″/>
</HOME_LIST>
</INVENTORY>
Save the file.
Now you retry the same command it should go through.
If you dont want to update your inventory.xml which is under the global inventory location, you can pass a parameter to the opatch utility to use a different inventory location provided that inventory has information about this oracle home.
opatch -invPtrLoc [New .loc file location]
Happy troubleshooting !!!!
cheers,
OraclePitStop.
