All OS Agents have a Job Messenger that can be used to run and monitor jobs. You call it in the HEADER and TRAILER of Include objects. These specific Include objects are available in the system client 0000. For more information, see Include Objects in Headers and Trailers.
A sample excerpt of the Include object HEADER.MVS:
//JMLDS EXEC PGM=&UC_JOBMD,
// PARM='JNR=&UC_REALNR MNR=&UC_CLIENT PNR=&UC_IP_PORT IPA=&UC_IP_ADR
// TYP=S TXT=" Job started" 2>&1'
A sample excerpt of the Include object TRAILER.MVS:
//JMLDE EXEC PGM=&UC_JOBMD,COND=EVEN,
// PARM='JNR=&UC_REALNR MNR=&UC_CLIENT PNR=&UC_IP_PORT IPA=&UC_IP_ADR
// TYP=E STP=&UC_REPORT_STEPS RET=&RETCODE 2>&1'
