RE: Problems with subversion

If I remember correctly Subversion 1.1 used Berkeley DB (BDB) for various purposes - for example the repository format might be BDB.

BDB relied upon file locking to enforce data consistency.

As I mentioned not all implementations of NFS servers fully implement file locking - this is why you are receiving these errors.

My recommendation is that you should migrate to a newer version of Subversion /and/ to a service based serving of the Subversion data rather than using file:// based access to the repository.

David.

Subject: RE: Problems with subversion
Hello,
I connect to a remote file system through a XVC terminal emulator.
Platform: UNIX linux
Subversion version: 1.1.4
Following my previous e-mail below,
I was able to establish that the problem resides in my repository.
Whenever I issue any subversion command to the repository like:
svnlook tree /altroot/ENGDATA/DeFRAC/defracdev/repository
The problem now I face is the following:
svn: Error opening db lockfile
svn: Can't get shared lock on file 'locks/db.lock': No locks available
It seems a file locking problem...
The output of command:
df -T /altroot/ENGDATA/DeFRAC/defracdev/repository
is the following:
Filesystem Type 1K-blocks Used Available Use% Mounted on
engarchive:/export/engarchive/ENGDATA
nfs 528417056 384972448 138160448 74% /altroot/ENGDATA
Any ideas?
Many thanks

Hello,
I have been using subversion for while now and without problems.
But recently when I was trying to commit my changes (svn commit -m "DeFrac final changes"),
from my local working copy, I got the following error message:
svn: Commit failed (details follow):
svn: Unable to open an ra_local session to URL
svn: Unable to open repository 'file:///ENGDATA/DeFRAC/defracdev/repository/maintv2/trunk<file:///\\ENGDATA\DeFRAC\defracdev\repository\maintv2\trunk>'
svn: Error opening db lockfile
svn: Can't get shared lock on file '/ENGDATA/DeFRAC/defracdev/repository/locks/db.lock': No locks available
I tried to issue the recover subcommand (svnadmin recover /altroot/ENGDATA/DeFRAC/defracdev/repository), but
still I received the following message:
Repository lock acquired.
Please wait; recovering the repository may take some time...
Recovery completed.
svn: Error opening db lockfile
svn: Can't get shared lock on file '/altroot/ENGDATA/DeFRAC/defracdev/repository/locks/db.lock': No locks available
I would appreciate your help.
Many thanks
