Exadata Lab 1: How To Change FlashCache Mode - WriteBack to WriteTrought

WriteBack to WriteTrought

1. First of all, we have to stop Cluster in All Database Node.
/u01/app/12.1.0.2/grid/bin/crsctl stop cluster -all

2. Execute commands in Cell Node

dcli -g mycells cellcli -e list cell attributes flashcachemode

dcli -g mycells cellcli -e drop flashcache

dcli -g mycells cellcli -e alter cell flashcachemode=WriteBack

dcli -g mycells cellcli -e alter cell startup services cellsrv

dcli -g mycells cellcli -e list cell attributes flashcachemode

dcli -g mycells cellcli -e create  flashcache all

dcli -g mycells cellcli -e list metriccurrent FC_BY_DIRTY



3. Now, We can start Cluster service in Database Node
/u01/app/12.1.0.2/grid/bin/crsctl start cluster -all
/u01/app/12.1.0.2/grid/bin/srvctl status database -d dbm

4. In CELL NODE
dcli -g mycells cellcli -e list metriccurrent FC_BY_DIRTY
