Shutting down the CSL SCI

Before shutting down the Structured Call Interface (SCI), consider the reasons for shutting down and how shutting down the SCI can impact other IMSplex members. There are multiple ways of shutting down SCI.

Recommendation: Shut down SCI by shutting down the CSL as one unit.

To shut down the SCI, do one of the following:

  • The system operator can use a z/OS® STOP command: 
    P scijobname
    scijobname is the job name of the SCI address space to stop.
  • Issue the CSL SHUTDOWN command.
  • Issue the CSLZSHUT request.

If no clients are connected to SCI, the SCI shuts down. However, if there are registered members on the local z/OS image, message CSL0300I is issued, and SCI does not process any new requests or messages from local members. After all in-flight requests have completed or timed out, the SCI address space terminates.
