In order to enable the Job Messenger to establish a TCP/IP connection, the appropriate DD statements need to be included in the Include object. Otherwise, jobs would switch over to the status ENDED_VANISHED.
The Include object MVS.JOBMD_DEFINITIONS does not have to be adjusted unless the MVS or Language Environment Resolver work incorrectly.
This situation can be avoided by creating an Include object with the name MVS.JOBMD_DEFINITIONS in the system client 0000. In it, you can enter the particular DD statements. The whole statements are found in the started task of the TCP/IP.
Example:
//SYSTCPD DD DSN=TCPIP.SYSTSMS.TCPPARMS(DT20OEDA),DISP=SHR
//PROFILE DD DSN=TCPIP.SYSTSMS.TCPPARMS(DT20VIPA),DISP=SHR
The Include is called in the Header upon the execution of a job. The Header is an object called HEADER.MVS which, by default, is supplied in the system client 0000.
