1.6.1 Handling of cluster systems
Since JP1/AJS3 for EAP has no information to take over at the time of failover, cluster resource registration is unnecessary. To install JP1/AJS3 for EAP in a cluster system, install it on each of the physical nodes of the cluster system.
- Important
-
If you fail over JP1/AJS3 in a cluster environment, and then re-execute any SAP linkage jobs that were being executed when JP1/AJS3 was failed over, the same SAP linkage job is sometimes executed multiple times on the SAP system. Before re-executing SAP linkage jobs from JP1/AJS3 after a failover, check the statuses of the jobs on the SAP system side, and verify that no problems occur when you re-execute the jobs.
