IMSPLEX statement

The optional IMSPLEX statement registers IMS Connect as a member of an IMSplex and enables both IMS type-2 command support for IMS Connect and communications between IMS Connect and other members of the IMSplex.

An IMSplex is built on the IMS Common Service Layer (CSL). Communications in an IMSplex are managed by the CSL Structured Call Interface (SCI). IMS type-2 commands are processed by the CSL Operations Manager (OM). After an IMS Connect instance registers with SCI in an IMSplex, the IMS Connect instance supports IMS type-2 commands and can communicate with other members of the IMSplex.

IMS Connect must be registered with SCI in the IMSplex to provide the following support:
  • TCP/IP support for Intersystem Communication (ISC) TCP/IP links between IMS and CICS® IBM® CICS Transaction Server for z/OS®
  • TCP/IP support for Multiple Systems Coupling (MSC) links between MSC-enabled IMS systems
  • TCP/IP access to IMS databases through the CSL Open Database Manager (ODBM)
  • IMS type-2 command support

You can join an IMS Connect instance to more than one IMSplex by specifying multiple IMSPLEX statements.

Certain other configuration statements in the HWSCFGxx member include an IMSPLEX substatement that can be used instead of the IMSPLEX statement. The IMSPLEX substatements allow IMS Connect to join an IMSplex for a specific purpose. The following configuration statements include an IMSPLEX substatement:
  • The ISC statement for ISC support
  • The MSC statement for MSC support
  • The ODACCESS statement for communications with CSL ODBM
Note: An IMS Connect instance can register only a single name in an IMSplex. If the IMSPLEX statement and the IMSPLEX parameter on another configuration statement in the HWSCFGxx member of the IMS PROCLIB data set both specify the same IMSplex name on TMEMBER parameter, they must also specify the same IMS Connect name on the MEMBER parameter.

IMSPLEX statement parameters

MEMBER=
A 1- to 8-character alphanumeric name that identifies IMS Connect in the IMSplex that is specified on the TMEMBER parameter of this IMSPLEX statement. The name must start with an alphabetic character.IMS Connect registers this name with SCI. SCI uses the name to manage communications between IMS Connect and the other members of the IMSplex.
TMEMBER=
The name of the IMSplex that IMS Connect is joining, as specified on the IMSPLEX(NAME= ) statement of the CSLSIxxx member of the IMS PROCLIB data set of the SCI instance that is managing communications between IMS Connect and the IMSplex.
Restriction: The name specified on the TMEMBER parameter cannot be the same as the name specified on the ID parameter of any DATASTORE statement or substatement in the HWSCFGxx member of the IMS PROCLIB data set.
