SYSPLEX permits DB2 Connect to seamlessly transfer an incoming connection from one remote database server to a designated backup server in the event that the first server fails. DB2 Connect support for SYSPLEX is enabled by default, however each DCS database catalog entry must be configured to enable SYSPLEX support.
| Note: | If the DB2 Connect concentrator is not active, then active connections are not transferred between hosts in the event of server failure; if a server fails all existing connections to that server are lost. If the concentrator is active, then only connections with inflight transactions to the particular SYSPLEX member that goes down will be lost. Other connections will be maintained and the next transaction will be sent to a remaining member. |
