處理Oracle 11gR2 RAC資料庫資源不能自動啟動的問題

In 11gR2 grid infrastructure installations certain resources may have auto start set to never and restore. This was observed both on environments where clusterware was upgraded to 11.2 as well as newly installed environments. Depending on the situation these may not be desirable. Auto start attribute setting could be changed as follows.

1. Check the current auto start values

# crsctl stat res -p
NAME=ora.FLASH.dg
TYPE=ora.diskgroup.type
ACL=owner:oracle:rwx,pgrp:oinstall:rwx,other::r--
ACTION_FAILURE_TEMPLATE=
ACTION_SCRIPT=
AGENT_FILENAME=%CRS_HOME%/bin/oraagent%CRS_EXE_SUFFIX%
ALIAS_NAME=
AUTO_START=never      

NAME=ora.DATA.dg
TYPE=ora.diskgroup.type
ACL=owner:oracle:rwx,pgrp:oinstall:rwx,other::r--
ACTION_FAILURE_TEMPLATE=
ACTION_SCRIPT=
AGENT_FILENAME=%CRS_HOME%/bin/oraagent%CRS_EXE_SUFFIX%
ALIAS_NAME=
AUTO_START=never     

NAME=ora.clusdb.db
TYPE=ora.database.type
ACL=owner:oracle:rwx,pgrp:oinstall:rwx,other::r--
ACTION_FAILURE_TEMPLATE=
ACTION_SCRIPT=
ACTIVE_PLACEMENT=1
AGENT_FILENAME=%CRS_HOME%/bin/oraagent%CRS_EXE_SUFFIX%
AUTO_START=restore

2. Since ASM diskgroup that database depend on will never auto start database will also be unavailable.

3. Change the resource start attribute with

# crsctl modify resource "ora.FLASH.dg" -attr "AUTO_START=always"
# crsctl modify resource "ora.DATA.dg" -attr "AUTO_START=always"
# crsctl modify resource ora.clusdb.db -attr "AUTO_START=always"

Auto start must be upper case if not command will fail

crsctl modify resource ora.clusdb.db -attr "auto_start=always"
CRS-0160: The attribute 'auto_start' is not supported in this resource type.
CRS-4000: Command Modify failed, or completed with errors.

4. Verify the status change with

# crsctl stat res -p
NAME=ora.clusdb.db
TYPE=ora.database.type
ACL=owner:oracle:rwx,pgrp:oinstall:rwx,other::r--
ACTION_FAILURE_TEMPLATE=
ACTION_SCRIPT=
ACTIVE_PLACEMENT=1
AGENT_FILENAME=%CRS_HOME%/bin/oraagent%CRS_EXE_SUFFIX%
AUTO_START=always
