The enqueue server keeps critical data (that is, all locks currently in use by users in the system) in the lock table in the main memory. If the host fails, this data is lost and cannot be restored even when the enqueue server is restarted. All transactions that have held locks must therefore be reset.
For this reason, the enqueue replication server (ERS) is started on another machine which together with the standalone enqueue server (SCS) provides a high availability solution.
Note:
Enqueue Server run on MAIN MEMORY
ERS runs on SHARED MEMORY
tags: sap, en, ms, ers, rep, server, ha, replication,
