11gR2 Database with EBS R12 Perl lib version doesn't match executable version

Error:
While dbTechStack

RC-00110: Fatal: Error occurred while relinking of ApplyDBTechStack

Perl lib version (v5.8.4) doesn't match executable version (v5.10.0)
( Or )
Perl lib version (v5.8.8) doesn't match executable version (v5.10.0) at /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/Config.pm line 46.
Compilation failed in require at /d02/oracle/uatdb/11.2.0.3/appsutil/clone/ouicli.pl line 35.

Solution :

Setting the PERL5LIB environment variable on the Database tier

By default, the PERL5LIB environment variable is set to the following on the Database tier:

/perl/lib/5.8.3:/perl/site_perl/5.8.3:/appsutil/perl

But for an instance with 11gR2 Database, the perl version on the database tier is '5.10.0'. So the variable 'PERL5LIB' on the 11gR2 database tier needs to be set as follows:

export PERL5LIB=/perl/lib/5.10.0:/perl/site_perl/5.10.0:/appsutil/perl

Change PERL5LIB path in db context file and run adcfgclone again.
