IMS Connect support for IMSplex

TheIMS Connect support for IMSplex enables access to an OM in an IMSplex fromIBM® Management Console for IMS and Db2 for z/OS® (Management Console) or other OM command client through TCP/IP.

The IMSplex support accesses OM through the IMS SCI. The IMSplex statement in the IMS Connect configuration file (HWSCFGxx) defines IMS Connect for IMSplex support. If the IMSplex statement is omitted, then IMSplex support is not available.

IMSplex support sends IMS command string messages directly for a client (for example, the Management Console) to a selected OM within an IMSplex. One or more IMSplexes can be defined to IMS Connect to receive Management Console command messages. SCI is used to communicate between IMS Connect and the IMSplex. To gain access to the selected OM, include the IMSPLEX configuration statement in the IMS Connect configuration member in the IMS.PROCLIB data set.

The same security method (authentication of the userid, groupid, and password; or authentication of the userid, groupid, userid application name, and pass ticket) used for accessing data stores also applies to IMSplex support. An IMS Connect command message exit performs similar functions as an IMS Connect user message exit.

The OM command client exit routines (HWSCSLO0 and HWSCSLO1) are designed specifically for IMSplex support. The HWSCSLO0 and HWSCSLO1 exit routines are similar to the other user message exit routines provided by IMS Connect for client access to the data store. The HWSCSLO0 and HWSCSLO1 message exits are designed to be used only by OM command clients and cannot be used by any client that sends messages to a data store. The HWSCSLO0 and HWSCSLO1 exit routines process only command string messages from OM command clients and are delivered as object code only.
