SAP does not start

Question

Hi All,
I was experimenting with my SAP IDES and unfortunately it is not working now.
Here is the problem.
When I start the server, the dispwork.exe starts, but fails to connect to the message server. But message server runs successfully. Ultimately dispwork.exe stops.
Here is what I did and what I think the problem is..
I went to RZ11, and added a new parameter in the Instance server
i.e msg_server port = 2000.
Before doing that there was no parameter msg_server in RZ11.
Here is what trace file dev_ms says
trc file: "dev_ms", trc level: 1, release: "620"
[Thr 2680] Wed Mar 21 16:45:42 2007

[Thr 2680] *** ERROR => MsSCheckConnections: no response from client C0 (10.0.0.22) after 300 secs received [msxxserv.c   2885]
[Thr 2680] *** ERROR => MsSCheckConnections: disconnect now [10.0.0.22] [msxxserv.c   2889]
As you can see it is listening to port 2000, which I do not think works.
Please help me.
Thanks

Hello goel,
there could be many reason when SAP doesn't start specially (Disp+Work) Please check the following setting ....
1. Check Virtual Memory settings ...Change it upto 4096kb.
2. Check ur Environmental Variables : User Variables (JAVA_HOME) & System Variables(PATH) ... Check hav u mentioned JAVA path Correctly or not ? do compile JAVAC at c:\ ... in ur command prompt to check java set correctly or not.
3. Please make sure your windows 2003 server is DNS configured.If not you have to install and configure Microsoft Loop Back adaper (It would at least loop back to the same server like virtual DNS). You also enter c:/windows/system32/drivers/etc/hosts
<Your ipaddress> < Your hostname>
4. Check Your STARTUP Profile (Path : usr\sap\sid\sys\profile\START_DVEBMGS00) where in that profile check the bottom _DW=dispwork.exe line.... if u find #* before _DW then also your dispwork.exe won't run. #* means disable. so please check this file.
5. Lastly Check your Database... if its oracle .. check weather its in open mode or not. if database won't respond then also same prob will raise.
6. Check ur services...         
I hope this will help to solve your problem. If it's still exist please let us know.
