SAP PI7.11 sap instance is not srarting after the restart

[Former Member]

Hi

I restarted PI7.11 system and it is not coming up, even there no log files writing on to the work directory.

I can see very few log files, where I can’t fine the exact reason for that,  As this physical server is running with 2 other instances, I initially

suspected it as a memory issue or page file issue. I tried testing like shutting down the other 2 instances and try to start the PI instance

only, however the it is still failing to start.

Please find the attached log files, that to the files in the work directory are not normal, I can only se 2 logs files as dev_ms.new  and

dev_disp.new, which is not normal.

Rest of the log file are missing from the work directory..(dev_dw0….. ,dev_dispatcher,dev_server0…etc)

from the start up log files it says that SAP Instance was started.  when i try R3trans -d it returns with -0000, and says every thing is fine.

Please find the error messages on the work directory.

dev_ms.new:

Hi Phaneedra,

Follow the steps:

1. Stop the sap system

    stopsap

2. Kill all the process if running.

   ps -ef|grep <sid>adm

   In case of windows goto the task manager.

3. Then clear the ipc if (Linux system) or take a reboot of the server in case of windows

    cleanipc <$$> remove where $$ is the instance number

Kindly update.

With Regards

Hi Ashutosh

Got resolved , after rebooting the whole server , seems it was  memory issue. DIsplatcher faield to start.

Thanks for the response.

Hi Phaneendra,

It was a problem with semaphore which was holding the sap process as a result log file with new extention was generating.
