check $perl -v
check $which perl

if you have something different than: Perl Version v5.10.0 then set the $PERL5LIB and $PATH to the correct perl
The error probably comes from mismatch between the perl of some old $ORACLE_HOME before upgrade to 11.2.0

export ORACLE_HOME=/u01/saudi_arabia_ar/db/tech_st/11.2.0
export PERL5LIB=$ORACLE_HOME/perl/lib/5.10.0:$ORACLE_HOME/perl/site_perl/5.10.0:$ORACLE_HOME/appsutil/perl
export PATH=$ORACLE_HOME/perl:$ORACLE_HOME/perl/lib:$ORACLE_HOME/perl/bin:$PATH
check again perl version
$ perl -v
This is perl, v5.10.0 built for x86_64-linux-thread-multi
