server.shutdown not working

Hm, actually the process disappeared after 5-10min...

Hi,

Although I have stopped the server by ./server.shutdown, ps -ax says
Jazz server is still running; next ./server.shutdown leads to an exception
(the connection refused) and it is not possible to connect to the server.

I'm afraid if I kill the process the data will be lost.

What is wrong?

Hi Roman,

It is good news that the server eventually stopped. That said, we want to
ensure that shutdown is responsive, and there have been prior reports about
the server failing to shutdown completely. If you find that you have to
kill the process, the only potential for data lost would be a user or
background transaction that has not yet completed. The system should be
able to recover fine on restart.

If this happens again, we can help diagnose the problem if you can capture a
Java trace and attach it to a new work item, assigned to the Repository
component.

To capture the trace, on Windows type CTRL+BREAK at the console window; on
Linux run "kill -3 <pid>".

Thanks Ritchie, when it comes to Derby DB, do you see any potential risk
there?

Recently I had a discussion with a colleague of mine who pointed to a Derby
datafile corruption they experienced even in case of regular shutdown. Have
you heard about/experienced it?

Roman

Roman,

A quick search of our bug database turned up the following reports:

Team Concert crash make the database(derby) inconsistant (29378) (web)
Invalid checksum on Page Page(0,Container(0, 11057)), expected=135?296?395,
on-disk version=644?144?805 (40866) (web)

The first turned out to be a different problem, and in the second case, we
are not sure if an ungraceful shutdown was the cause. Generally we'd hope
that derby would be crash tolerant, but as with a commercial db, it's wise
to take nightly backups.

I can tell you that before the Jazz team scaled up to db2 we used to host
our own development on derby and we never experienced data corruption, even
though we had our share of server crashes :-(. We also stopped the server
nightly for backups.

Ok, so to get the backup you stopped the server and copied db files and then
started server again - is this correct?
