DSNR038I csect-name WARNING - THE TCP/IP RESYNCHRONIZATION PORT NUMBER IS CHANGED FROM port_1 TO port_2

Explanation

The TCP/IP resynchronization port number obtained from the DDF record of the BSDS is different than the value specified the last time Db2 started.

Changing the TCP/IP resynchronization port number can cause problems during distributed 2-phase commit processing. The remote DRDA partners record Db2 resynchronization port number in their recovery logs. The resynchronization port number is used to reconnect to the appropriate Db2 member when communication failures occur during 2-phase commit processing. If a Db2 member changes its resynchronization port number, the remote DRDA partners may be unable to resolve indoubt units of work.
port_1
The TCP/IP resynchronization port number that was obtained from the Db2 BSDS during Db2 startup.
port_2
The TCP/IP resynchronization port number that was obtained from the coupling facility during Db2 startup. This is the TCP/IP resynchronization port number that was used the last time this member was started.

System action

Db2 accepts the new TCP/IP resynchronization port number, and Db2 startup continues.

Operator response

Contact the system programmer.

System programmer response

If the Db2 resynchronization port number was changed inadvertently, stop Db2 immediately. Use the change log inventory utility (DSNJU003) to correct the RESPORT value, and restart Db2.

If this message reflects a change that you want to make to the Db2 resynchronization port number, no action is required. The resynchronization port number stored in the coupling facility for this member is updated, and this new port number will be used when Db2 validates the resynchronization port number for other Db2 members.
