How the system runs an ObjectConnect command

When an ObjectConnect command is issued on source system, a connection is established between the source system and the target system. The correspondent save command runs on the source system and the saved data is sent to the target system. The correspondent restore command runs on the target system and the received data is restored to the target system.

ObjectConnect over IP

ObjectConnect over IP receiver job QOBJCRCV is started on target system during the ObjectConnect server start-up. The receiver job listens on port 9841 to accept connection requests. Multiple ObjectConnect server jobs QOBJCSVR are started by the ObjectConnect receiver job to service the ObjectConnect operations. When the ObjectConnect command is called to run over IP, the connections are established over the IP network. Figure 1 shows the flow of the job. You can view the ObjectConnect jobs by working with the job name QOBJCRCV and QOBJCSVR. Type WRKACTJOB JOB(QOBJC*). You are shown the Work with Active Jobs display:

ObjectConnect over SNA

When you issue an ObjectConnect command to run over SNA, an ObjectConnect job is started on the target system and establishes a conversation with the target system. Figure 1 shows the flow of the job. You can view the ObjectConnect job by working with the subsystem. Type WRKACTJOB SBS(QCMN) if your systems are linked with communications support. Type WRKACTJOB SBS(QSOC) if your systems are linked with OptiConnect. You are shown the Work with Active Jobs display:

ObjectConnect for Db2 Mirror

ObjectConnect for DB2® Mirror receiver job QOBJCMRRCV is started when the System Object Replicate NRG becomes active. The receiver job listens on port 950 to accept connection requests. Multiple ObjectConnect server jobs QOBJCMRSVR are started by the ObjectConnect receiver job to service the ObjectConnect operations. When the ObjectConnect command are called to run for Db2 Mirror, the connections are established over System Object Replication Network Redundancy Group (NRG). Figure 1 shows the flow of the job. You can view the ObjectConnect jobs by working with the job name QOBJCMRRCV and QOBJCMRSVR. Type WRKACTJOB JOB(QOBJC*). You are shown the Work with Active Jobs display:
