I have a sde connection problem as "arcgis server service on local computer started and then stopped". I am using Oracle 11 g and ArcSde 10.0 on windows 7. I shut down the ArcSDE by command prompt (sdemon -o shutdown) but after that sde service is not working. I tried to start SDE service by manual but it is not working.
Unfortunately, I don't think you'll be able to resolve your issue. Some comments:
I recommend that you upgrade to a more recent ArcGIS release.
Hope this helps,
