This topic describes the configuration steps necessary to use S/390®, System i™, and zSeries® database servers within your TP monitor.You must have an operational TP monitor and have DB2 Connect™ installed, as well as have configured and tested a connection to the host or System i database server. To configure DB2 Connect to use S/390, System i, and zSeries database servers within your TP monitor, perform the following steps:
The SPM is a component of DB2 Connect which maps the XA two phase commit protocol into the two phase commit protocol used by host and System i database servers. By default, the DB2 instance has predefined values for the SPM configuration parameters. The most significant parameter is the database manager configuration parameter SPM_NAME. It defaults to a variant of the first seven characters of the TCP/IP hostname.
If you are using TCP/IP to connect to DB2 for OS/390® and z/OS®, then you should not have to change any of the default settings. In this case, there is no SPM configuration required since it is already operational.
