Thanks to all your input. We were able to complete the installation, as follows:
- After primary RAC nodes are installed; srvctl stop database; srvctl stop diskgroups (replicated LUNs).
- SA mount the LUNs on standby site (split mirror), then, we installed Grid Home and RDBMS Home.
- We were able to mount the LUNs on standby ASM. ASM automatically recognized the LUNs as MEMBER.
Afterward, we have to run these 2 commands to register database and service:
srvctl add database -d xxx -o $OHOME -p +DATA/xxx/spfilepocsim.ora -n xxx -c RACONENODE -e snode1,snode2 -i xxx -a "DATA,FRA,ARCH,REDO1,REDO2"
srvctl add service -s SERVICE_NAME -d xxx -P BASIC
(I found the above 2 commands from DB creation scripts automatically generated by DBCA; the trick is that we have to add REDO1,REDO2 to the -a option, as the generated commands by DBCA did not include REDO1/REDO2. Make sure you have all replicated diskgroups in the srvctl add database -a dg_list.)
I will bring up the issue to our architect when primary SAN crashes and last DB block is not replicated.
hi, we have a similar scenario.
From our Data Center we have a 2 node RAC and from our DR site we have a AIX server that also replicate the storage of our RAC from the data center. scenario will be, We will Install A single Instance and used the Replicate Copy of the storage of RAC as storage. Can you give me some advice on how can i make use of the replicate storage as the storage of the single instance? Is installing the Grid infrastructure and the RDBMS and copy the PFILE from the PRIMARY rac can make our Single Instance up?
Thanks in advance.
