Hi, we going to use SAP DB (v7.3.0.18) on a cluster system (HP L1000). The cluster consists of 2 nodes and a common RAID1 array (hardware) which can be accessed from both nodes and which is switched to the active node during operation. Each node has its own local harddrives (for OS etc., also RAID1). Our SAP DB setup is as follows (short discription):
We installed the SAP DB software on the local disks on both nodes. The database instance which should run on this cluster is created on the common RAID array by using the installtion of the DBMS on the active node. In order to switch the instance from one node to the other in case of a failover, one has to provide this other node with the informations about the database instance which are holded in the directory branches of ../indep_data and /var/spool/sql. So we moved these to one disk of the common RAID array and set soft links at former locations of these directory branches. This we did on both nodes. Now my question: How do I have to carry out an update of SAP DB software when using the configuration discribed above? Do I only have to process the update on the active node, then switch over to other node (to be able to access the common RAID array from the other node) and process the update a second time? Any hints would be helpful. Thanks in advance!
