Support for IBM DB2 pureScale

IBM DB2 pureScale (version 9.8) is certified for use with Maximo Asset Management 7.5.0.1, but has installation prerequisites and requires additional configuration.

For more information about DB2 pureScale, see http://www-01.ibm.com/software/data/db2/linux-unix-windows/editions-features-purescale.html

Installation prerequisites

If you plan to use IBM DB2 pureScale, you must configure your database server manually, install Maximo Asset Management 7.5 by following the instructions in the Installation Guide to deploy manually reusing existing middleware, and then install the Maximo Asset Management 7.5.0.1 fix pack.

DB2 configuration

All member instances on the DB2 pureScale server must have the same user ID and password so that seamless failovers can occur.

Maximo Asset Management configuration

After you install the 7.5.0.1 fix pack, configure the properties:

1. In the install_home\maximo\applications\maximo\properties\
maximo.properties file, replace the value of the mxe.db.driver property with the new value:

Old: mxe.db.driver=com.ibm.db2.jcc.DB2Driver
New: mxe.db.driver=psdi.server.CustomDriverProxy

2. In the properties folder, create a file named customdriver.properties.

3. In the customdriver.properties file, define the name of the driver by adding the following line:

realdriverclass=com.ibm.db2.jcc.DB2Driver

4. In the customdriver.properties file, enable seamless failover by adding the following line:

property.enableSysplexWLB=true

5. (Optional) In the customdriver.properties file, add additional properties that you want to specify in the JDBC connection by prepending them with the word property and a period, similar to the enableSysplexWLB property.

Failover messages in the log

When a failover occurs, a -30108 exception is thrown to the Maximo Asset Management error log, but processing continues.
