Symptoms:




Cannot launch Perl script in Smarts SAM 9.x using standard Perl.
When trying to use Perl script in Smarts SAM 9.x, the following can be seen in the logs:

Environment

VMware Smart Assurance - SMARTS

Cause

In Smarts 7.x and 8.x, the Smarts Perl module was made to be loaded with standard Perl. With 9.x, the module must be loaded using sm_perl. Use of standard  Perl is no longer supported by the Smarts architecture in 9.x, sm_perl must be used.

 

The sm_perl module was designed especially for Smarts and has many additional parameters and configurations that are required to run the Smarts Perl API. To ensure that these required customizations are loaded, you must use sm_perl.

 

The PerlApi depends on two C modules:

• FlowWrapper - For features like encrypted client-server communication, keepalives and so on.
• I18NWrapper - I18N support - proper rendering of error messages etc. This was added in DMT 9.0.

The underlying issue is that the libI18NWrapper.so was compiled and linked against Perl 5.8.8 libraries. It relies on symbol Perl_Tstack_sp_ptr, which is defined in toolbox/perl/lib/5.8.8/x86_64-linux-thread-multi/CORE/libperl.so in a Smarts server installation. This symbol is not defined on some later versions of Perl.

Resolution

If you need to run without sm_perl in Smarts 9.x while using the Smarts Perl API, you need to include the appropriate options on the perl command line. sm_perl includes the following, which can be seen by looking at SM_PREPEND_ARGS in [local/]bin/system/sm_perl.options in a Smarts server installation:

sm_edit bin/system/sm_perl.options

You will need to add some "-I" entries to the SM_PREPEND_ARGS variable as shown in the following:

 

SM_PREPEND_ARGS="-I "$SM_HOME"/local/perl/lib -I "$SM_HOME"/perl/lib -I "$SM_DEFHOME"/local/perl/lib -I "$SM_DEFHOME"/perl/lib -Msm_perl_init -I "$SM_HOME"/local/perl/5.8.8/lib -I "$SM_DEFHOME"/local/perl/5.8.8/lib -I "$SM_HOME"/perl/5.8.8/lib -I "$SM_DEFHOME"/perl/5.8.8/lib -I "$SM_HOME"/local/perl/5.8.8 -I "$SM_DEFHOME"/local/perl/5.8.8 -I "$SM_HOME"/perl/5.8.8 -I "$SM_DEFHOME"/perl/5.8.8 -I "$SM_PERL_BASE"/lib/5.8.8 -I "$SM_DEFHOME"/toolbox/perl/lib/5.8.8 -I "$SM_PERL_BASE"/lib/5.8.8/x86_64-linux-thread-multi -I "$SM_DEFHOME"/toolbox/perl/lib/5.8.8/x86_64-linux-thread-multi "

 

You also need to set your path and/or library path, which is usually handled by runcmd.
 

-I /usr/lib/perl5/vendor_perl/5.8.8/ -I /usr/lib/perl5/site_perl/5.8.8
