#ENQUEUE REPLICATION SERVER INSTALL#
Use the sapstartsrv.exe command to create an SAP Windows Service for the Enqueue Replication Server instance. As per my understanding, we can install en enqueue replication server (ERS) in other host (B), but in case of fail over, the sap instance needs to be started in. It is essential that the binaries from (A)SCS and ERS instance are from the same binary set. If the (A)SCS instance has not configured DIR_CT_RUN in its profiles, take the value specified for DIR_EXECUTABLE from the (A)SCS instance profile. Start_Program_02 = local $(_ER) pf=$(_PFL) NR=$(SCSID)įor DIR_CT_RUN in this ERS profile, take the value DIR_CT_RUN from the (A)SCS instance profile. _ER = $(DIR_EXECUTABLE)\enrepserver$(FT_EXE) For a detailed description of relationships and their properties, see System Automation for Multiplatforms Administrator's and User's Guide. # standalone enqueue details from (A)SCS instance Relationships between the Enqueue and Message Servers and the Enqueue Replication Server A set of example scenarios explain the functions of these relationships. # Settings for enqueue monitoring tools (enqt, ensmon) Start_Program_01 = immediate $(DIR_CT_RUN)\sapcpe$(FT_EXE) pf=$(_PF) _PF = $(DIR_PROFILE)\PLL_ERS11_sapershost SAPSYSTEMNAME = PLLĭIR_CT_RUN = $(DIR_EXE_ROOT)\$(OS_UNICODE)\NTAMD64ĭIR_INSTANCE = :\usr\sap\$(SAPSYSTEMNAME)\$(INSTANCE_NAME) failover cluster, mscs, ers, ascs, scs, enqueue replication server, 11114, KBA, BC-OP-NT, Windows, BC-CST-EQ, Enqueue, Problem About this page This is a preview of a SAP Knowledge Base Article. Create a new ERS instance profile in drive:\usr\sap\PLL\SYS\profile. Copy all the binaries from (A)SCS instance exe directory into the ERS instance exe directory. The same cluster shared disk drive S is shared between them. • On one of the physical hosts ( host A or host B) perform the following steps as user sidadm or domain administrator:Ĭreate the directory structure as follows: With Enqueue server replication 1 architecture: The same is used to access the SAP message and enqueue server processes, and the SAP global host files via the sapmnt file share. You can view the logs in the VCS engine log, engine_A.log. The preonline script is now configured to facilitate Enqueue and Enqueue Replication server behavior.
