srdf high availability for sap java and oracle db
Hello,
I am new to EMC srdf. I am an SAP Basis administrator. Currently planning to move SAP Java-only Portal from Windows to Solaris. New design has 2 HA nodes at 2 geographically close datacenters. Design includes Veritas Cluster and EMC srdf. Is there a document that clearly explains how to setup filesystems, clustering and srdf to acheive high availability? Is this design valid - can HA be acheived?
Thanks in advance for replies,
Tamara

Hi,
That is very useful info. One thing I am missing is to know what requires SRDF. For SAP HA, an enqueue replication process must run on the passive node. This filesystem obviously should not be replicated. It is unclear if Oracle executable filesystems should be implemented with SRDF. I am always comparing how the current system is implemented on Windows MSCS, there sqlsvr executables are installed on both nodes. But this setup is different (Solaris x86,VCS,EMC VMax SRDF) - it seems that Oracle executables as well as Oracle db files should be replicated. The storage administrators have designated all of the filesystems to to SRDF. Is it possible to have all storage SRDF but not use it? Is it possible to have some Luns on the server non-srdf and some srdf? So many questions!
Thanks in advance for replies,
Tamara
