一个客户的AIX系统中,启动数据库报错ORA-27504

这个错误的描述为:

ORA-27504: IPC error creating OSD context
Cause: This is an operating system/cluster interconnect error.
Action: Check the value of errno and contact Oracle Support Services.

从字面上看,似乎错误和CLUSTER有关,但是实际上是AIX上没有打开用户网络参数的限制。

执行下面的设置后,重新尝试启动数据库,问题消失:

/usr/sbin/no -o udp_sendspace=65536
/usr/sbin/no -o udp_recvspace=655360
/usr/sbin/no -o tcp_sendspace=65536
/usr/sbin/no -o tcp_recvspace=65536
/usr/sbin/no -o rfc1323=1
/usr/sbin/no -o sb_max=1310720
/usr/sbin/no -r -o ipqmaxlen=512

将这些修改添加到系统启动脚本中,避免重启后出现同样的错误。
