RESYNC PORT field
The value of the RESYNC PORT field specifies the TCP/IP port number that is to be used to process requests for two-phase commit resynchronization.
| Acceptable values: | 1–65534 |
|---|---|

This value must be different than the values that are specified for TCP/IP PORT and SECURE PORT. If you are enabling data sharing, each member must have a unique resynchronization port. Leaving this field blank means that you are not using TCP/IP. A blank field is equivalent to using 0 in the change log inventory (DSNJU003) utility.
Db2 uses the resync port only for transaction completion states after failures, so no user data or authentication protocols are ever exchanged on the resync port. You can enable SSL security for the resync port by defining a network policy on all Db2 requesters and Db2 servers.
