Help About Instance Manager memory

netbeta

OS:Redhat AS4 (Kernel2.6)
DB2 level: 8.2 fixpack 10

kernel.shxmax = 2147483648  (2G,物理内存4G，虚拟内存4G)

当前instance dbm 的instance memory配置为INSTANCE_MEMORY 262144  (1G)
db2start时提示"SQL1220N The database manager shared memory set can not be allocated" error

另外一个instance 可以正常启动


求助！！！

I hit this problem before also but the next day this problem does not occur anymore....
So far still dont know what is the root caused.

最后实在没办法，drop掉该instance，重新db2icrt，本地添加数据库解决，但很奇怪。db2dump log记录调用了一个非法的系统功能，提示os error。

if you don't mind, can you please post the error message to here so that we can discuss together.
