Example of group access configuration

Applications that use group access use the group's Db2 location name (DB2A) to direct connection requests to the group.

The configuration in the figure below is an example of group access that uses DNS network addressing
Figure 1. Example TCP/IP network configuration (DNS network addressing)
Begin figure summary. A domain name server is configured with the IP addresses of the members in the data sharing group. Detailed description available.
Note: When a Db2 for z/OS® system is a member of a data sharing group, Db2 cannot be used as a DRDA XA server. As a result, the XA Transaction Manager cannot directly access the Db2 for z/OS DRDA server. Instead, you must configure the DRDA requester system in such a way that it insulates the Db2 for z/OS DRDA server from receiving XA calls from the XA Transaction Manager.
