Short term do what you have to of course!
But in my experience Oracle interestingly enough is one of the best behaved

A lot of this depends on the size of the database in the machi

I ended up using the #cp vi vmsg 0 1 method.
Prior to deleting /var, I created the new disk space first. I updated

We have some very large LVM2 filesystems, and have only seen one issue.
As you add PV's to a VG, the time it takes for the utilities (pvscan,
pvs, etc.) to run increases exponentially with the number of volumes.
This is because LVM2 puts metadata on every volume by default, and the
utilities seem

We actually opened an issue with IBM over this. Here's what I got back:

drivers as noted in the man page. It's very typical that for an
gigabit NIC (especially a fiber connection) will not have a valid

I'm confused about how much overhead seems to be involved in creating a
volume group that approaches a terabyte with ECKD devices (A mix of some

That's because, as Mark said, you're attached to a virtual device, and
the "speed" doesn't have much meaning. Any data flowing Linux to
Linux within the same vswitch could flow much faster than a gigabit,
but data flowing out the physical port is limited by the connection on
that port. The virtua

On RHEL5.2 -- we're using mii-tools and seeing that the ethernet interface

something special needs to be done to set it to gigabit speeds.. Using

Hi,
Remember that you have 15 seconds, by default, to enter this command.
I'm not so fast, so I prefer to record my options on PF keys, like this
model of PROFILE.EXEC:
/*/
'CLOSE RDR'
'CP PURGE RDR ALL'
'SWAPGEN B000 1000 (DIAG'
'SWAPGEN B001 500 (DIAG'
"CP SET PF1 #CP
