srvctl和crs_start命令无法启动oracle RAC实例, 但sqlplus可以启动

今天遇到一个奇怪问题，发现srvctl和crs_start命令无法启动Oracle RAC实例，但用sqlplus却可以正常启动。最终发现原因是在OCR中数据库的状态变成了disable，将此状态更改为enable后恢复正常。

以下是一个模拟示例：

oracle@his00mlcdrc02:~ $> crs_stat -t
Name           Type           Target    State     Host

oracle@his00mlcdrc02:~ $> ps -ef | grep ora_
  oracle 23001 16923   0 16:31:27 pts/1       0:00 grep ora_

oracle@his00mlcdrc02:~ $> crs_start ora.hisdrcdb.hisdrcdb2.inst
Attempting to start `ora.hisdrcdb.hisdrcdb2.inst` on member `his00mlcdrc02`
Start of `ora.hisdrcdb.hisdrcdb2.inst` on member `his00mlcdrc02` failed.    (在节点his00mlcdrc02上启动失败）
his00mlcdrc01 : CRS-1019: Resource ora.hisdrcdb.hisdrcdb2.inst (application) cannot run on his00mlcdrc01
(对于象VIP这类可以failover到其它节点的资源，如果在原节点上启动不成功，则Oracle会试图在其它节点上启动。而实例是不能failover的资源，此处提示实例2不能在节点1上启动)
CRS-0215: Could not start resource 'ora.hisdrcdb.hisdrcdb2.inst'.

oracle@his00mlcdrc02:~ $> crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....SM1.asm application    ONLINE    ONLINE    his0...rc01
ora....01.lsnr application    ONLINE    ONLINE    his0...rc01
ora....c01.gsd application    ONLINE    ONLINE    his0...rc01
ora....c01.ons application    ONLINE    ONLINE    his0...rc01
ora....c01.vip application    ONLINE    ONLINE    his0...rc01
ora....SM2.asm application    ONLINE    ONLINE    his0...rc02

ora....rcdb.db application    OFFLINE   OFFLINE
ora....b1.inst application    OFFLINE   OFFLINE
ora....b2.inst application    ONLINE    OFFLINE
此时可以看到实例2启动并未成功。

oracle@his00mlcdrc02:~ $> srvctl start instance -d hisdrcdb -i hisdrcdb2
用srvctl命令尝试启动实例2，命令很快就返回了。

oracle@his00mlcdrc02:~ $> crs_stat -t

ora....b1.inst application    OFFLINE   OFFLINE
ora....b2.inst application    ONLINE    OFFLINE
srvctl命令启动也不成功。

先把实例2停止。

oracle@his00mlcdrc02:~ $> ocrdump

查看OCRDUMPFILE

......
OCR中显示数据库DATABASE.DATABASES.hisdrcdb.ENABLED属性为false，DATABASE.DATABASES.hisdrcdb.POLICY为manual,而在别的数据库上可以看到这两个属性应为true和automatic.

oracle@his00mlcdrc02:~ $> srvctl status database -d hisdrcdb -f
Instance hisdrcdb1 is disabled
Instance hisdrcdb1 is not running on node his00mlcdrc01
Instance hisdrcdb2 is disabled
Instance hisdrcdb2 is not running on node his00mlcdrc02
srvctl状态表明数据库被disable了。

oracle@his00mlcdrc02:~ $> srvctl enable database -d hisdrcdb
oracle@his00mlcdrc02:~ $> srvctl status database -d hisdrcdb -f
Instance hisdrcdb1 is not running on node his00mlcdrc01
Instance hisdrcdb2 is not running on node his00mlcdrc02
用srvctl命令enable database

oracle@his00mlcdrc02:~ $> ocrdump ocr1
查看ocr1:
......
[DATABASE.DATABASES.hisdrcdb.ENABLED]
ORATEXT : true

ORATEXT : AUTOMATIC
SECURITY : {USER_PERMISSION : PROCR_ALL_ACCESS, GROUP_PERMISSION : PROCR_WRITE, OTHER_PERMISSION : PROCR_READ, USER_NAME : oracle, GROUP_NAME : dba}

此时这两个属性恢复为true和automatic.

再次用crs_start命令则能够正常启动实例。

附：srvctl disable disables target, meaning CRS will not consider it for automatic startup, failover, or restart. This option is useful to ensure an object that is down for maintenance is not accidentally automatically restarted.

srvctl enable reenables the specified object.
