 +==== CPAN coredumps on AIX ====
 +
 +Answer
 +
 +AIX does not set maxdata because it causes issues for AIX Perl-based commands.
 +
 +One of the following solutions can usually resolve the issue:
 +
 +1) Use the 64-bit module
 +
 +2) export LDR_CNTRL=MAXDATA=0x80000000@DSA
 +
 +3) Use a perl.rpm version (which is recommended for reasons that are listed in the AIX Perl Updates and Support for perl.rte technote), then use ldedit to permanently set the maxdata value
 +
 +  # ldedit -b maxdata=0x80000000 "path to perl.rpm Perl binary" ​
 +
 +==== CPAN install modules offline ====
 +
 +Download Perl module
 +
 +Go to CPAN Search website and search for the module that you wish to download. In this example, let us search, download and install XML::Parser Perl module. I have downloaded the XML-Parser-2.36.tar.gz to /​home/​download
 +<cli prompt='#'>​
 +# cd /​home/​download
 +# gzip -d XML-Parser-2.36.tar.gz
 +# tar xvf XML-Parser-2.36.tar
 +# cd XML-Parser-2.36
 +</​cli>​
 +<cli prompt='#'>​
 +# perl Makefile.PL
 +Checking if your kit is complete...
 +Looks good
 +Writing Makefile for XML::​Parser::​Expat
 +Writing Makefile for XML::Parser
 +# make
 +# make test
 +# make install
