DSNL042E csect-name DB2 SYSPLEX TP WAS INVOKED BY LU lu, BUT REQUIRED MVS LEVEL IS NOT INSTALLED

Explanation

A request for the Db2 sysplex transaction program (TP) was received by a Db2 server that is a member of a data sharing group. The Db2 sysplex TP is used by the requesting systems to determine which Db2 systems within the group are currently available for DDF conversations.

The Db2 sysplex TP uses Workload Manager (WLM) functions in MVS Version 5 Release 2 or a later release to balance distributed workload among the Db2 systems in the group. Because the required MVS release is not installed or Db2 is not registered with WLM, the Db2 sysplex TP is not able to provide the requested information.

The name of the LU in the network that invoked the Db2 sysplex TP

System action

The Db2 sysplex TP returns the NETID.LUNAME of the local Db2 system as the only available Db2 server in the group. The requester is not provided the names of other Db2 systems in the group, so all sessions from the requester are routed to the local Db2 server.

System programmer response

Install MVS Version 5 Release 2 or a later release if you want to have the Db2 sysplex TP return multiple NETID.LUNAME values to the requester or refer to the DSNL044I on why Db2 could not register with WLM.
