# Error:

dbsrvr1:/home/oracle>srvctl start database -d mydb
PRCR-1079 : Failed to start resource ora.mydb.db
CRS-5017: The resource action "ora.mydb.db start" encountered the following error:
ORA-27154: post/wait create failed
ORA-27300: OS system dependent operation:semget failed with status: 28
ORA-27301: OS failure message: No space left on device
ORA-27302: failure occurred at: sskgpcreates
. For details refer to "(:CLSN00107:)" in "/grid/product/11.2.0.4/log/dbsrvr2/agent/crsd/oraagent_oracle/oraagent_oracle.log".
CRS-2674: Start of 'ora.mydb.db' on 'dbsrvr2' failed
CRS-2632: There are no more servers to try to place resource 'ora.mydb.db' on that would satisfy its placement policy

Seems the weeror is happening on dbsrvr2, right?
The doc below talks more about the error and the semaphores calculation:
Database Startup Fails with ORA-27300: OS system dependent operation:semget failed with status: 28 (Doc ID 949468.1)

Let’s make an adjust here:

[root@dbsrvr2 ~]# cat /etc/sysctl.conf |grep sem
kernel.sem = 250 32000 100 142
[root@dbsrvr2 ~]# vi /etc/sysctl.conf
[root@dbsrvr2 ~]# cat /etc/sysctl.conf |grep sem
kernel.sem = 250 32000 100 256
[root@dbsrvr2 ~]# sysctl -p

And try again:

dbsrvr1:/home/oracle>srvctl start database -d mydb
dbsrvr1:/home/oracle>

Well done! 😀
