Upgrading Your DB2 Software
Upgrades: All upgrades.
Environments: Development environment only.
Before you upgrade, use the Certifications tab on My Oracle Support to verify that you are using currently supported versions of the following DB2 software:
DB2 for z/OS. If you are using an earlier version of DB2 for z/OS than the versions currently supported, you must migrate to a supported version before you upgrade to the current release of Siebel CRM.
DB2 Connect. Siebel Developer Web Client (Siebel Mobile Web Client in connected mode) and Siebel Servers communicate with DB2 for z/OS through DB2 Connect middleware. Verify that you are using the version of DB2 Connect supported for the current release of Siebel CRM.
