+==== 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:
+) Use the 64-bit module
+) export LDR_CNTRL=MAXDATA=0x80000000@DSA
+) 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
+</cli>
