Adding plperlu Language to Greenplum on RHEL5

In order to get plperlu added as a language on our Greenplum 4.0RHEL5 cluster I had to take a couple additional steps. My first unhappy message was

db=# CREATE LANGUAGE plperlu;
ERROR: ¬†could not load library “/usr/local/greenplum-db-”: cannot open shared object file: No such file or directory
db=# CREATE LANGUAGE plperlu;ERROR: ¬†could not load library “/usr/local/greenplum-db-”: cannot open shared object file: No such file or directory

So greenplum can’t find

[gpadmin@mdw ~]$ locate


Looks like it’s on the system so I just need to make it available

[root@mdw ~]# echo “/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE/” > /etc/

[root@mdw ~]# ldconfig

Next I went out and did the same thing on all the nodes using gpssh. Then it’s back to the master and we try to create the language again

db=# CREATE LANGUAGE plperlu;


Time: 892.420 ms

I should note that I tried to install plperl on the SLES11 servers we had and ran into an issue because the version of perl on SLES11 is 5.10 and unfortunately the within Greenplum’s distro is looking for 5.8. I didn’t look for a fix because I knew we were going to jump to Redhat in the near future and it would work there.


Adding Documentation

Doing the most exciting of all tasks, I’m adding documentation to the site.

Greenplum Command references at : GP COMMANDS

Greenplum Documentation at: DOCS

I find myself constantly sharing my latest GP Admin guide with other people so I figured this would be a great spot to drop the pdf documentation that you’ll find in the release packages. It would also be handy to keep a running log the various documentation attached with each release.

Additionally I’m using <command> -? constantly to get the help from the program I want to run. So I put these up on the site too in order to make it easier to get at those outputs.
