Failed to retrieve procctx from ht. constr错误
Failed to retrieve procctx from ht. constr错误
给一个客户巡检时发生这样的少见的集群报错:
[ OCRSRV][1220598112]th_select_handler: Failed to retrieve procctx from ht. constr = [-1734303600] retval lht [-27] Signal CV.
遇到这种报错我想到的就是:
1.检查系统防火墙和selinux有没有关闭
2.检查心跳线有没有问题，是直连还是通过交换机？交换机有没有做防火墙设置？
3.是否用了第三方的集群软件
4.确定两边的私网网卡的MTU设置是否一样，是否超过了交换机允许的MTU的最大值？
结果查完后都发现没有问题，只能查询Metalink,结果搜出来一条:
METALINK:crsd.log: th_select_handler message repeated (文档 ID 338693.1)
和我们的RAC描述的一样，ORACLE官方给出的建议如下：
SOLUTION
This message can be ignored as described in unpublished bug 4494370.
Schedule a maintenance window and turn off this messaging as user root on one of the clusternodes:
# crsctl debug log crs OCRSRV:0
Stop and start CRS after changing the tracing level to pick up the change.
