Configuring DB2 pureScale Feature

To introduce DB2® pureScale® Feature to your topology, you must configure the database server and modify the system properties.

Before you begin

You can configure your product for seamless failover with DB2 pureScale Feature only after installing the product and the relevant fix pack. For example, for Maximo® Asset Management customers, a minimum of Maximo Asset Management 7.5.0.1 fix pack must be installed. The product can be installed to a DB2 pureScale Feature environment, but if a failure occurs during the installation process, failover is not possible.

About this task

To allow seamless failover, all member instances on the DB2 pureScale Feature server must have the same user ID and password. For more information about installing IBM® DB2 pureScale Feature, see the Installing or upgrading to the DB2 pureScale Feature section of the DB2 Knowledge Center.

Procedure

  1. In the install_home\maximo\applications\maximo\properties\maximo.properties file, replace the mxe.db.driver property with the following new value: mxe.db.driver=psdi.server.CustomDriverProxy
  2. In the install_home\maximo\applications\maximo\properties\ directory, create a file named customdriver.properties and add the following properties to the file:
    1. To define the name of the database driver, add the following property: realdriverclass=com.ibm.db2.jcc.DB2Driver
    2. To enable seamless failover, add the following property: property.enableSysplexWLB=true
  3. Optional: You can add any additional properties that you want to specify in the JDBC connection in the customdriver.properties file, by adding the prefix property. to the property name. For example, the enableSysplexWLB property is in the customdriver.properties file because it is modified for seamless failover.
  4. Rebuild and deploy the Maximo EAR files.
