semaphore locked
Hi Friends,
ORACLE 10g Linux RHEL 4.6
I issue command # ipcs -a and the following is the result :
[root@prod1 ~]# ipcs -a
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 524288 gdm 600 393216 2 dest
0xf8fdbf50 557057 oracle 660 1075838976 46
------ Semaphore Arrays --------
key semid owner perms nsems
0xcbb4e678 229376 oracle 660 204
------ Message Queues --------
key msqid owner perms used-bytes messages
==================
I noticed that there is 1075838976 used by oracle? Is the the physical memory?
But when I issue TOP commnad , I can see that the used memory is almost 4GB
Mem: 4150328k total, 3922364k used, 227964k free, 28336k buffers
Where are the other memory users? If I shutdown both OracleDB and OracleApps (EBS), The memory held is still 2GB and the ipcs -a commnad does not show any memory holders. Why is the memory being locked-in?
Please help
