OPNDLIM

The OPNDLIM system initialization parameter specifies the open destination and close destination request limit. (Not required for currently supported releases of z/OS® Communications Server.)

Defining OPNDLIM

You can define the OPNDLIM system initialization parameter in the following ways:
  • On the PARM parameter of the EXEC PGM=DFHSIP statement
  • In the SYSIN data set of the CICS® start up job stream
  • Through the system console
  • In the DFHSIT macro

Values for OPNDLIM

Valid values for the OPNDLIM system initialization parameter are as follows:

OPNDLIM={10|number}
10 is the default value for OPNDLIM. This limit is used to restrict the number of concurrent OPNDSTs and CLSDSTs to prevent the z/OS Communications Server from running out of space in the CICS region. The limit may be any value in the range 0 through 999. When large values are used for OPNDLIM, the value on the EDSALIM system initialization parameter and the value on the z/OS REGION parameter may need to be adjusted to ensure that enough operating system storage is available.
