Dispatcher problems

[Former Member]

Hi,

I have problems with the initiating the dispatcher+work service. The dispatcher gets to the running state but cannot connect to the message server and after that stops the whole process. The developer trace shows the following error message:

• ERROR => DpShMCreate: ShmCreate SHM_DP_CA_KEY(rc=4) [dpxxca.c 181]

• ERROR => DpIPCInit2: DpShMCreate [dpxxtool2.c 431]

• DP_FATAL_ERROR => DpSapEnvInit: DpIPCInit2

• DISPATCHER EMERGENCY SHUTDOWN ***

What could be the problem?

Thanks.

Hi,

This error is commonly happen in dispatcher log and is due to some shared memory remained.

If you are running unix system, do a cleanipc command and reboot your server.

If you are running windows, do a clean reboot.

Hi,

there are two possibilities

1. a system with the same system number is still running.

2. Another process is attached to the shared memory and it can't be

deleted. Check whether the start service is still running and

stopp it. Then try to restart the system

Please make sure

no disp+work with the same instance-number is running on this box

(it could also bee that there is an old instance of dpmon or MMC

is running).

Now if this is not the case then there can be a kernal problem.Just check the above things and let me know.
