操作系统:AIX6.1 数据库:Oracle10.2.0.5 RAC
2个节点。其中一个节点正常,另外一个节点的instance的状态是offline的,手工去启动的时候报错:
ORA: IPC error creating OSD context ORA: OS system dependent operation:sendmsg failed ORA: OS failure message: Message too long ORA: failure occurred at: sskgxpsnd1 ORA: additional information: MTU verification failed to send msg.
问题原因 :节点间 udp_sendspace、udp_recvspace 参数不一致
解决办法:
no -p -o udp_sendspace=65535
no -p -o udp_recvspace=655350
