Anton,
The folks here that evaluated Open Source database systems seemed to
find PostgreSQL to be a much more robust solution. They've been using
it here in production for at least 3 years on zLinux. The database is
small ( 100GB) but is quite active. The application is written in Perl
and it
We've been running a WebSphere application for a few years on 4-WAS V5.0
app servers on separate zLinux-SLE8-31bit z/VM guests. The virtual
memory size of each guest was 1GB and the maximum heap size in the JVM
was set to 768MB. These systems do little or no swapping and can run
for days and

Hello,
We have a filesystem which is shared by 4 Linux guests via NFS. We have
been using this setup for quite some time. Recently we've seen 2 cases
where access to the NFS file on 1 or more of the non-owning guests began
to slow down. A df command on the effected system would stop before

- No changes have been made to z/VM.
- These are 1G WebSphere guests, each with 768MB java heap size.
- All other commands work fine on all 4 servers. Only commands going
against the NFS, e.g. df, ls, on the effected system(s) run slowly
until that system is bounced.
- z/VM has 17GB
Alan,
I will try those commands the next time we see the problem. The df and
ls commands against the NFS do eventually return, after 10 to 20
seconds, so data is actually moving, albeit slowly.
Thanks,
Hank

On occasion, the DB2 work will slow to a crawl for several minutes and a

Hello,
I have twice experienced a problem where at boot time fsck determined that the
root filesystem (ext3) was broken. fsck was run at boot time because the
system determined that root has been mounted 26 times without being checked.
The system was up and running minutes previous to this
