Specifying the DRDA port number

Db2 requires that all members of a data sharing group use the same, well-known port number to receive incoming SQL requests.

446 is the recommended DRDA port number. DRDA port numbers are stored in the bootstrap data sets (BSDSs) of members.

Use installation panel DSNTIP5 or the DSNJU003 (change log inventory) utility to specify the DRDA port number (PORT) for each member. Specify the same DRDA port number for all members of the same data sharing group.

The network administrator must also register the DRDA port number with TCP/IP on each member's z/OS® system.
