Hi,
Is your perl question still valid ?
Perl is shipped with the 9i/10g RDBMS and with Apps iAS and used for a multitude of things inc. cloning scripts and db interrogation scripts.
I've just upgraded Apps with 3480000 (11.5.10.2), HRMS K et al, but did not necessiate a perl upgrade. Did require some config on DB tier (set ADPERLPRG and PERL5LIB) as not set in context file. This was required to AutoConfig enable RDBMS OracleHome.
Any specific area of perl use you need info on?
