R12 AppsLocalLogin shows blank page

This issue has already been reported to me twice, so I am documenting this for future:

R12 AppsLocalLogin shows blank page

A check of logs shows this:

cd $LOG_HOME/ora/10.1.3/j2ee/oacore/oacore_default_group_1
vi application.log

If you open two unix sessions side by side:

First session: connect to sqlplus as apps and execute
select fnd_web_sec.validate_login('GUEST','ORACLE') FROM DUAL;

Second session: tail Database alert log

You'll notice that whenever this sql is executed in first session, the alert log will immediately log an ORA-07445 error.

This is an 11.2.0.2 bug. The workaround is to bounce the database and listener. Once I learn more about this bug, I'll update this post.

Can't locate strict.pm in @INC

On running adcfgclone.pl on 11.2.0.2 RDBMS ORACLE_HOME, the following error occurred.

$ perl adcfgclone.pl dbTechStack
Can't locate strict.pm in @INC (@INC contains: /erpR1213/oracle/11.2.0/perl/lib/5.8.3 /erpR1213/oracle/11.2.0/perl/lib/site_perl/5.8.3 /erpR1213/oracle/11.2.0/appsutil/perl ../lib/5.10.0/sun4-solaris-thread-multi-64 ../lib/5.10.0 ../lib/site_perl/5.10.0/sun4-solaris-thread-multi-64 ../lib/site_perl/5.10.0 ../lib/5.10.0 ../lib/5.10.0/sun4-solaris-thread-multi-64 ../lib/site_perl .) at adcfgclone.pl line 27.

This is a known issue and now documented in My Oracle Support Article ADPreclone Fails When Can't Find Strict.PM Following Database Upgrade to 11gR2 [ID 1139403.1].

11.2.0.2 ships with perl 5.10.0. So you need to change the values of context variables pointing to PERL5LIB and ADPERLPRG inside the context file.

vi $CONTEXT_FILE
Global replace 5.8.3 with 5.10.0
Save
cd $ORACLE_HOME/appsutil/template
vi adxdbctx.tmp
Global replace 5.8.3 with 5.10.0

Run adcfgclone.pl, or adconfig or adpreclone.pl and it will work now.
