Changes to the Status of the Operation
The operation with the NVxx workstation goes through several status changes as the request defined in the operator text is processed.
The initial trigger is one of three status changes. When the operation moves to the A (arrival), R (ready), or * (ready with non-reporting predecessor) status, the TWS Automation function in the EQQUX007 exit is triggered. The exit then examines the request. If the request is valid, the exit transfers it to the target NetView.
If any definition problems are determined, TWS Automation updates the status to E with an error code of Uxxx. See IBM Z® System Automation Messages and Codes. TWS Automation takes no further action. The user is then responsible for correcting the error and restarting the application at the failed operation.
If TWS Automation encounters a connectivity problem, it marks the operation with a status of E (error) and an error code of Sxxx. If this happens, TWS Automation automatically restarts the operation once the connectivity problem is resolved. However, if the operation status is changed manually, the automatic restart is suppressed.
After TWS Automation resolves the request and verifies it, the status is updated to S (started) before TWS Automation submits it. Once the request is submitted and action is requested, TWS Automation updates the status to C (completed).
If the desired result did not occur within the time period specified, the operation ends with an E status and a Uxxx code, indicating that user intervention is required.
