DFS3606I wwww EXTERNAL SUBSYSTEM INITIALIZATION FAILED, FC = xxxx, RC = yy, JOBNAME = zzzzzzzz

Explanation

Initialization exit processing was unsuccessful for the external subsystem (wwww). The external subsystem returned a nonzero return code. The function code, xxxx, indicates the module that detected the error. This module can be an IMS or external subsystem exit module. For the function code value and the module name that detected the error, see the IMS return codes and function codes information. The return code yy, set by the detecting module, indicates the function that failed in the detecting module.

To distinguish one region from another, JOBNAME = zzzzzzzz is also provided. This information is necessary because all the supported regions must do initialization processing.

For the function code values defined in IMS DSECT DFSESFC, see the IMS return code and function code information.

System action

IMS initialization continues. Subsystem connections are not established. In the IMS control region, when the initialization exit processing fails in this manner, the TCB representing the external subsystem connection is terminated without an abend.

In the dependent region case, the following list of return codes indicates the IMS action:
yy = 08
Initialization unsuccessful - IMS does not initiate a connection to the subsystem for the life of this IMS-dependent region execution.
yy = 20
The external subsystem supplied exit has encountered an invalid condition while processing the request. If an application is involved, it terminates with a 3044 abend.
yy = ??
Unsupported return code received from the initialization exit. If an application is involved, it terminates with a 3049 abend.

Operator response

Notify the proper installation personnel about the receipt of this message, then follow the installation action.

Programmer response

Correct the indicated problem, and restart the failing external subsystem connection using the IMS /START SUBSYS command, or, if an application program was involved, restart the application using /START TRAN, UPDATE TRAN START(Q,SCHD), and /START PROGRAM commands.
yy = 08
The error was encountered by the external subsystem initialization exit; see the external subsystem documentation for the action to take.
yy = 20
The error was encountered by the external subsystem initialization exit; see the external subsystem documentation for the action to take.
yy = ??
The error was encountered by the external subsystem initialization exit; see the external subsystem documentation for the action to take.
