communication error during CC/RTC sync

Gary Dang (593●2●87●55) | asked Jul 10 '08, 12:29 a.m.
When trying to import 1GB of data from ClearCase to RTC, sync failed after 167 minutes. It seems to be a connection issue. Any comment on how to avoid such errors? Thanks.

You are right about the connection problem. It looks like you are losing your connection to the DB2 server that you are using to hold your Jazz data.

Have you checked the DB2 logs to see if there is anything wrong with the DB2 server?

Hi Gary,

When you say 1GB of data, was this one big (1GB) file, or lots of files
that added up to 1GB of content?

Cheers,
Geoff

There are about 1500 files on over 200 folders/sub-folders. Some of the folders and files had been successfully imported before the failure.

Thanks, Matt.

Which log files on DB2 side should we look at? Thanks.

Unfortunately, I don't know much about diagnosing DB2 errors. Perhaps
the DB2 documentation could point you at the log files, or somebody else
on the forum could help diagnose the problem.

You can try looking at db2diag output around the time of the disconnect
to see what the DB2 server was doing.
