disp+work.exe started but then stopped

Dear All,

I have installed SAP on Windows 2003 and database is Oracle 10g with SYSTEM ID 'TST'.

I have taken Oracle EXPORT DUMP from Production system which is on HP-UX (SYSTEM ID 'PRD') and IMPORT in TST database.

Now when I start SAP disp+work.exe started but then stopped.

Is it due to diffrent SYSTEM ID on production and test system?

I have check port no. it is ok.

Thanks in advance,

Nirav
