Install DB2 for z/OS

This section provides information on how to install DB2 for z/OS for use with IBM WebSphere Portal. The following prerequisites must exist separately from the WebSphere Portal installation:

• Configure your DB2 Connect client with the following commands:

  • db2 update dbm cfg using tp_mon_name WAS

  • db2 update dbm cfg using spm_name hostname, where hostname is the host.name for the machine where the DB2 Connect client is installed (same as portal machine).

• Enable extended shared memory usage with the following commands:

  export EXTSHM=ON db2set DB2ENVLIST=EXTSHM db2start
  

  To make the change permanent, add the environment variable by adding the following to the profile.env file:

  DB2ENVLIST='EXTSHM'
  

  in /home/db2inst/sqllib/userprofile add:

  export EXTSHM=ON
  

  The shell must be reopened before restarting DB2 for z/OS.

• Both type 2 and type 4 drivers are supported. If you are using the DB2 Legacy Type 2 JDBC driver, the DB2 Connect client must be installed on the same machine as WebSphere Portal to connect to the remote database.

• The DB2 subsystem must be on a supported z/OS platform.

• Update the BP8K0 catalog bufferpool to add 20,000 buffers before performing database transfer. The SYSIBM.SYSDATABASE table resides in this bufferpool and is used extensively by DB2 for z/OS during database transfer.

To use DB2 for z/OS as the database software for WebSphere Portal, have DB2 for z/OS installed on your z/OS system. Refer to the DB2 for z/OS product documentation for instructions. Refer to the Planning for DB2 for z/OS topic for additional considerations for configuring DB2 for z/OS as the WebSphere Portal database.
