Update database tier nodes with the Oracle E-Business Suite Release 12.1.3 code level.
After upgraded to Oracle E-Business Suite Release 12.1.3, perform the following post-update steps to update all database tier nodes with the code level, provided by Oracle E-Business Suite Release 12.1.3:
Application tier:
As the APPLMGR user, run the environment file for the current APPL_TOP.
. .$APPL_TOP/APPS$CONTEXT_NAME.env
Run AutoConfig on the APPL_TOP.
Run the admkappsutil.pl utility to create the file appsutil.zip in the $INST_TOP/admin/out directory.
perl $AD_TOP/bin/admkappsutil.pl
Database tier:
As the ORACLE user, run the environment file for the current ORACLE_HOME.
cd [RDBMS ORACLE_HOME]
. ./[RDBMS ORACLE_HOME]/$CONTEXT_NAME.env
. ./[RDBMS ORACLE_HOME]/$CONTEXT_NAME.env
Copy or FTP the appsutil.zip file to the [RDBMS ORACLE_HOME].
Uncompress appsutil.zip under the [RDBMS ORACLE_HOME].
cd [ORACLE_HOME]
unzip -o appsutil.zip
unzip -o appsutil.zip
Run AutoConfig on the [RDBMS ORACLE_HOME]
Re-run adpreclone.pl on the database tier and the application tier.
Since updates included in Oracle E-Business Suite Release 12.1.3 were applied to the system, adpreclone must be run again to apply the updates to the clone directory structures that were used during cloning.
perl adpreclone.pl dbTier
perl adpreclone.pl appsTier
perl adpreclone.pl appsTier
Disable Maintenance mode
adadmin menu_option=DISABLE_MAINT_MODE workers=4 defaultsfile=$APPL_TOP/admin/$TWO_TASK/adalldefaults.txt logfile=adadmin_DISABLE_MAINT_MODE.log
Remove the fast validation for PL/SQL recompilations from init parameter and restarted the database.
Restarted the application Tiers
Cheers!!!
