一个朋友新装的一套oracle 11.2.0.4版本的RAC发现节点一的实例状态为unknown，在启动集群资源的时候发现instance没有被集群带起来。

crsd.log中报错信息如下：

Could not forward message [RESOURCE_CLEAN[ora.testdb.db 1 1] ID 4100:6053] to agent. /opt/app/11.2.0/grid/bin/oraagent_oracle is not running

两个节点的oraagent的状态不一样：

节点二：ps -ef | grep oraagent grid 3211 1 0 12:04:45 ? 0:50 /opt/app/11.2.0/grid/bin/oraagent.bin grid 3830 1 0 12:05:50 ? 0:24 /opt/app/11.2.0/grid/bin/oraagent.bin oracle 6046 1 0 12:12:42 ? 0:57 /opt/app/11.2.0/grid/bin/oraagent.bin grid 3204 26634 1 13:39:21 pts/4 0:00 grep oraagent

节点一： RAC01:/home/grid> ps -ef | grep oraagent grid 5077 1 0 11:46:17 ? 1:05 /opt/app/11.2.0/grid/oraagent.bin grid 5938 1 0 11:47:41 ? 0:35 /opt/app/11.2.0/grid/bin/oraagent.bin grid 29140 19598 0 13:39:15 pts/2 0:00 grep oraagent

处理方法是按照如下文档建立相关目录并赋予相关权限。

根据metalink文档1935758.1

Symptoms

SRVCTL cannot STOP or START database on one node.

SQLPLUS can start the database.

[oracle@rac-node1~]$ srvctl start instance -d ints -i INTS1

PRCR-1013 : Failed to start resource ora.ints.db

PRCR-1064 : Failed to start resource ora.ints.db on node rac-node1

CRS-2680: Clean of 'ora.ints.db' on 'rac-node1' failed

CRS-5802: Unable to start the agent process

crsctl status resource -t

..

ora.ints.db

1 ONLINE UNKNOWN rac-node1

2 ONLINE ONLINE rac-node2 Open,Readonly

Cause

Couldn't start the agent process.

Issue with folder permissions, the sticky bit on agent folder is missing :

[oracle@rac-node1]$ ls -ld $ORACLE_HOME/log/rac-node1/agent/crsd/oraagent_oracle

drwxrwxrwx. 2 oracle oinstall 4096 Aug 22 10:52 /407/apps/u01/oragi/11.2.0/grid/log/rac-node1/agent/crsd/oraagent_oracle

Solution

Setting the sticky bit fixed the problem.

[oracle@rac-node1~]$  ls -ld /407/apps/u01/oragi/11.2.0/grid/log/rac-node1/agent/crsd/oraagent_oracle

drwxrwxrwt. 2 oracle oinstall 4096 Aug 22 10:52 /407/apps/u01/oragi/11.2.0/grid/log/rac-node1/agent/crsd/oraagent_oracle
