JCMON Error: Can't open shared memory administration (rc=-107)

[Former Member]

Hello:

After apply a new Framework (patch SPS18), although the J2EE starts without problem (3 jlaunch in running status), the jmon doesn't work. The following message is displayed:

Can't open shared memory administration (rc=-107)

Command to start: ./jcmon pf=/usr/sap/MIP/SYS/profile/MIP_DVEBMGS00_cfmobint

Any idea of what could be happening?

Is this UNix or Windows ?

If it is Unix, shut down JAVA again , do cleanipc and make sure to kill any of the java processes before starting java again.

Thanks!

Hello Sean:

Thanks for you reply....

No, the java is started, in dev_dispatcher and dev_server0 the process appears on running state, and the URLs are working. J2EE is working without problems.

Hi,

Can you check the profile file you are passing as parameter.Is it the correct one?

It should be <SAPSID>_<INSTANCE_ID>_<HOST>.

Thanks & Regards,

Hi there,

The message thrown by is usually displayed when java stack is down. Did you try checking logs under \usr\sap\SID\DVEBMGSxx\j2ee\cluster\ and java homepage?

regards, Sean.
