CPSMCONN

The CPSMCONN parameter specifies whether you want CICS® to invoke the specified CICSPlex® SM component during initialization of the region.

CPSMCONN={NO|CMAS|LMAS|WUI}
You can initialize the region as one of the following:
  • A CICSPlex SM address space (CMAS)
  • A CICSPlex SM local managed application system (MAS)
  • A CICSPlex SM Web User Interface (WUI) server
NO
Do not invoke any CICSPlex SM initialization code in this region.
CMAS
Invoke CICSPlex SM code automatically during CICS initialization to initialize the region as a CMAS. The other information CICSPlex SM needs for a CMAS is taken from the CMAS parameters read from the EYUPARM data set.

Specifying CPSMCONN=CMAS is the recommended alternative to specifying the CICSPlex SM CMAS initialization program in a CICS post-initialization program list table (PLTPI).

Note: If you specify CPSMCONN=CMAS, ensure that your CICS region startup JCL EXEC statement specifies the name of the CICSPlex SM CMAS program, EYU9XECS. For example:
//CMAS    EXEC PGM=EYU9XECS,…,…
LMAS
Invoke CICSPlex SM code automatically during CICS initialization to initialize the region as a local MAS. The other information CICSPlex SM needs for a MAS is taken from the MAS parameters read from the EYUPARM data set.

Specifying CPSMCONN=LMAS is the recommended alternative to specifying the CICSPlex SM MAS initialization program in a CICS post-initialization program list table (PLTPI).

WUI
Invoke CICSPlex SM code automatically during CICS initialization to initialize the region as a CICSPlex SM WUI server. The other information CICSPlex SM needs is taken from the MAS and WUI parameters read from the EYUPARM and EYUWUI data sets respectively.

Specifying CPSMCONN=WUI is the recommended alternative to specifying the CICSPlex SM MAS and WUI initialization and shutdown programs in initialization and shutdown program list tables (PLTPI and PLTSD).

Note: Using the CPSMCONN parameter has the same effect as specifying the relevant CICSPlex SM program in a program list table. This means that MASPLTWAIT and other PLT-related CICSPlex SM parameters are still valid and should be specified as necessary. However, there differences in the way the user ID under which the CICSPlex SM component runs is derived:
  • If the CICSPlex SM component is started by a PLT program, it runs under the authority of the PLTPIUSR. For more information, see PLTPIUSR.
  • If the CICSPlex SM component is started by CPSMCONN, then the ID is derived as follows:
    • If a Program List Table is specified on the PLTPI system initialization parameter, it runs under the authority of the PLTPIUSR. For more information, see PLTPIUSR.
    • If no Program List Table is specified on the PLTPI system initialization parameter, it runs under the authority of the CICS region user ID.

For more information about the user ID under which PLT programs run, see PLT programs.
