EMI 3 APEL

The APEL client has been rewritten.

APEL Parsers

There is now one package for all the APEL parsers - you need to configure which type of batch system you are using. You will need to install:

• apellib
• apelparsers

The dependencies are MySQL-python and python-ldap, which are both in the SL repositories. The parsers will connect to a mysql database on an emi-apel machine, which must also be the EMI3 version.

Configuration is in /etc/apel/parser.cfg. The parser will typically run from a cron job.

Upgrade installation

If necessary, it should be simple to upgrade APEL Parsers from an older version. However, the EMI-3 version will only work with the EMI-3 version of APEL Publisher (4.0.0).

yum remove glite-apel-core glite-apel-<type>   # <type> is pbs, sge or lsf
rm /etc/cron.d/glite-apel-<type>-parser        # if present 
yum install apel-parsers                       # note that now there is one package for all parsers

You can then follow the standard installation instructions.

APEL Publisher

Only install the EMI-3 version of APEL Publisher if you are also planning to install EMI-3 versions of the APEL Parsers.

You need to install:

• apellib
• apelclient
• apelssm

You will need to install a new mysql database.

The dependencies are:

• stomppy
• python-ldap
• mysql-server
• mysql
• python-dirq
• python-daemon

All of these are either in the SL or EPEL repositories.

Upgrade installation

It is not sensible to try an upgrade installation, because everything has changed - the packages, and the database schema. You should install the APEL Publisher on a new machine.
