Procedure to change the port number of an existing Shareplex replication.
설명
By default Shareplex uses port 2100 for TCP and UDP. There are times when one needs to change this default port #. The following are examples of such situations:
1. A port in the server is hung and trying to start sp_cop on such port results in errors. 2. The port number needs to conform to a new standard requiring renumbering of port #. 3. A port # has been erroneously set differently either on source or on target, requiring it to be amended on one server so as to match with the other server.
원인
Port number of a replication environment needs to be changed.
해결 방안
Changing the port # for a replicating environment is very simple and does not cause any damage to the replication environment, queues, etc. One needs to do the following on both source and target:
1. shutdown Shareplex gracefully (normal) 2. Change the environment variable SP_COP_TPORT and SP_COP_UPORT to the new port # either at the environment level or in paramdb, while making sure that it does not conflict with a port already used by some application (Shareplex or otherwise). 3. Restart Shareplex.
