ORA-27106: system pages not available to allocate memory

Run the IPCS command to list Interprocess Communication (IPC) status as follows.

[root@node1 ~]# ipcs -a

Now find the process of destroyed process using their shmid as follows.

[root@node1 ~]# lsof | grep 399835141

oracle_19 194509 oracle DEL REG 0,15 399835141 /SYSV00000000

oracle_24 247335 oracle DEL REG 0,15 399835141 /SYSV00000000

[root@node1 ~]#

Now kill these process :

[root@node1 ~]# kill -9 194509 247335

[root@node1 ~]# [root@node1 ~]# [root@node1 ~]# lsof | grep 399835141

[root@node1 ~]# [root@node1 ~]# ipcs -a

Now our memory space released, we can startup the database.
