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
- 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
- In the install_home\maximo\applications\maximo\properties\ directory,
create a file named customdriver.properties and
add the following properties to the file:
- To define the name of the database driver, add the following
property: realdriverclass=com.ibm.db2.jcc.DB2Driver
- To enable seamless failover, add the following property: property.enableSysplexWLB=true
- 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.
- Rebuild and deploy the Maximo EAR files.
