DSNJ251E csect-name DATA SET dsname FAILS TO MEET THE MINIMUM REQUIRED SHAREOPTIONS FOR DATA SHARING.

Explanation

The share options defined for the data set named in the message are too low to permit the data set to participate in a Db2 data sharing group. All active log data sets must be defined with SHAREOPTIONS(2 3) or higher in order to participate in a data sharing group.

System action

The Db2 subsystem detecting this error is terminated.

System programmer response

Using IDCAMS LISTCAT or TSO LISTCAT, display the share options of all of the active log data sets of all of the members in the data sharing group. For any active log data set that is defined with less than SHAREOPTIONS(2 3), use IDCAMS ALTER or TSO ALTER to alter the data set definitions to SHAREOPTIONS(2 3) or higher.

Problem determination

If you suspect an error in Db2, you might need to report the problem. For information about identifying and reporting the problem, see Collecting diagnostic data.

Collect the following diagnostic items:
  • Console output from the system on which the job was run, and a listing of the SYSLOG data set for the period of time that spans the failure.
  • Dynamic dump, taken to SYS1.DUMPxx data set, by Db2 (04E and 04F abends).
  • A listing of the SYS1.LOGREC data set, obtained by executing IFCEREP1.
  • IDCAMS LISTCAT output that shows the attributes of all active log data sets for the Db2 member that failed.
