PSBCHK

The PSBCHK system initialization parameter specifies whether CICS® is to perform PSB authorization checks for remote terminal users who use transaction routing to initiate a transaction in this CICS region to access an attached IMS system.

Defining PSBCHK

You can define the PSBCHK system initialization parameter in the following ways:
  • In the PARM parameter of the EXEC PGM=DFHSIP statement.
  • In the SYSIN data set of the CICS startup job stream.
  • In the DFHSIT macro.
You cannot define the PSBCHK system initialization parameter through the system console.

Values for PSBCHK

PSBCHK={NO|YES}
Valid values for the PSBCHK system initialization parameter are as follows:
NO
NO is the default value for PSBCHK. The remote link is checked, but no check is made against the remote terminal. This value is the default.
YES
The remote link is checked, and the remote terminal is also checked if RESSEC(YES) is coded in the definition of the transaction in the CSD.
Note: If you require DL/I security checking, you must specify the XPSB system initialization parameter as XPSB=YES or XSPB=name. For further information about the XPSB system initialization parameter, see XPSB.
Restriction: You can specify the PSBCHK parameter in the SIT, PARM, or SYSIN only.
