We have a windows service written in VB.NET.
This service is used to trigger applications. The functionality of the service can be briefly explained as

1. The Service accesses the Oracle database.
2. Checks the status of certain table entries.
3. Depending on the table entries processes are triggered.
4. The Service is a perpeterating one with a periodicity of 2 minutes.

Issue:

1. The service is installed and is started. It is functioning as expected. Now the Database is brought down (say for backup) and is brought up again.
When the Database is brought down the service is not able to access the database which is expected.
Now when the database is brought up the service still persists with the error.

ERROR from the service:
--------------------------------
ERROR MESSAGE : ORA-01034: ORACLE not available

ORA-27101: shared memory realm does not exist

SVR4 Error: 2: No such file or directory
--------------------------------
A manual restart of the service is required to make the service functional again.

Software Details
-------
Oracle Version : Oracle 9i Enterprise Edition,
                            Release 9.2.0.4.0
.NET Framework: Microsoft .NET 2003, v1.1.4322
------

The service works well on Windows 2003 server but this issue comes in Windows 2000 server SP4.

Any inputs on this will be of help
