RE: How to know Oracle Down ?

For a small nominal fee I'm sure that someone can come up with a discarded pc that will run UNIX (Linux or Solaris) that will monitor your NT servers. OR
 How about using the Win scheduler to run a script to connect to the Oracle DB and select sysdate from dual.
If you can't then the DB is down.

Works great and you don't have to reinvent the wheel just for NT.

You can easily check if you can make a connection. The rest ???/ well, I am not sure. I use a real OS..... (Ok, so I am a Unix Biggot).

Are you sure you can do that with NT? NT makes Oracle one large process called "Oracle.exe", I know there are programs that will let you see the individual processes though.

        For me the easiest way is to just try and log on to the db, if you can't,
it's gone:)

1. Your users complain loudly .....
2. First check to see if your smon processes are running. If it is not then you know oracle is down. If it is up then check a query against the catalog. If you get what you expect then Oracle is up. From this information you can then either set a value on a web page or e-mail someone if you have problems or whatever.

Hi Xperts,

Platform is Windows NT Server SP-6 , Oracle Enterprise Edition 8.1.6

Question:

1. How do I know before someone tells me that Oracle is down ( e.g. in Unix we check dbw process )
2. If Oracle is Down , Why ? means which file should be looked for the possible causes.

Thanks,
Harsh
