Recently we had a DR(Disaster Recovery) testing going on and we had RAC replica at the DR site for DR testing. Device/File not configured. The redo can also contain BWRs. In many cases, simply reinstall the driver is not fix things; you have to clean the old corrupt driver before installing the new. Check compute nodes are up: [root@v1ex1dbadm01 ~]# dcli -g /opt/pportTools/onecommand/dbs_group -l root 'hostname; uptime' v1ex1dbadm01: v1ex1dbadm01: 18:21:55 up 12 min, 1 user, load average: 0.

Now, try to stop the complete cluster from the first node (oel72-rac1). Start and Stop RAC Services –. Both GCS and GES use messages containing information to ensure that the current block image can be located. Note: Not able to stop the newly added node (oel72-rac3).
Nothing seems to work. Block transfer times by the LMS process within RAC can be determined using the formula below with values from V$SYSSTAT or GV$SYSSTAT: (global cache cr block build time +. 6. scroll and click ' Save Settings '. Cache fusion also allows nodes to copy dirty blocks over the interconnect instead of the node having the dirty block writing it to disk and then the requesting node reading it from disk. To start cluster resources of all nodes, run the following command: [root@dbn01 ~]# /u01/app/12. In this real life scenario, the NFS server was taken offline for a relocation without offlining the quorum disk first. Instance B issues a select against a block with SCN 123. Step 3: Instance C initiates IO request to the disk. A global cache element is an Oracle-specific data structure representing a cache fusion resource. This section will list which objects in the database are the busiest in relation to Cache Fusion. Cannot communicate with Cluster Ready Services.
