Error:

On checking the logfile, it is understood that the issue is with PERL Paths in the context file.

Reason:

The environment is created as shared storage multi node. The second node was cloned from the first, but in the context file, the PERL related paths were not identical to that in first node

The paths in failed node

<ADPERLPRG oa_var="s_adperlprg" osd="unix">/usr/bin/perl</ADPERLPRG>

<PERL5LIB oa_var="s_perl5lib" osd="LINUX_X86-64">/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi:/usr/lib/perl5/site_perl/5.8.8:/usr/lib/perl5/site_perl:/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi:/usr/lib/perl5/vendor_perl/5.8.8:/usr/lib/perl5/vendor_perl:/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi:/usr/lib/perl5/5.8.8:.:/u01/E-BIZ/apps/apps_st/appl/au/12.0.0/perl:/u01/E-BIZ/apps/apps_st/appl/au/12.0.0/perl</PERL5LIB>

Fix:

Edited the perl paths (ADPERLPRG  and PERL5LIB) in the context file and made it identical to that in first node and restarted the services.

Paths after editing:

<ADPERLPRG oa_var="s_adperlprg" osd="unix">/u01/E-BIZ/apps/tech_st/10.1.3/perl/bin/perl</ADPERLPRG>

<PERL5LIB oa_var="s_perl5lib" osd="LINUX_X86-64">/u01/E-BIZ/apps/tech_st/10.1.3/perl/lib/5.8.3:/u01/E-BIZ/apps/tech_st/10.1.3/perl/lib/site_perl/5.8.3:/u01/E-BIZ/apps/apps_st/appl/au/12.0.0/perl:/u01/E-BIZ/apps/tech_st/10.1.3/Apache/Apache/mod_perl/lib/site_perl/5.8.3/i686-linux-thread-multi</PERL5LIB>

Restart service in second node after this.
