Virtual Oracle database in VMware vSphere 4.0

There's a big discussion going on at my workplace about virtualizing Oracle databases. It used to be not done because of performance, but it offers many really useful features such as hardware independence, fail-over, VMotion and cloning, vmdk copies, etc.

Oracle had previously told us they supported Oracle in VMs. When they announced Oracle VM Server based on Xen, they retracted this statement. We weren't impressed. Microsoft tried to do the same things while they were working on Hyper-V and so on. Eventually, anti-monopoly laws forced them to support competitors in the same way as they support their own virtualization flavor. So I expect Oracle to do the same. In the mean time... we're playing with Oracle Xen thingy as well as investigating virtual databases running on VMware 4.0 aka vSphere.

Preventing PuTTY timeouts

Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.

Removing VGs or LVs from LVM

While are many excellent tutorials about creating and using LVM on Linux, not may show you how you can remove disks from LVM Volume Groups (VG) and reclaim storage or how to remove a Logical Volume (LV) from your LVM set-up. Here is what I did: Use -t to TEST ANY LVM action first! We are going to release 1 TB from LVM. The Volume group was extended with 1 TB storage to serve as a cheap NFS/CIFS file server when setting up our data center. It is now deprecated and replaced by a NAS so it's no longer needed. 1) check LVM; note the four 256 GB LUNs [root@server ~]# pvscan -v Wiping cache of LVM-capable devices Wiping internal VG cache Walking through all physical volumes PV /dev/sdb1 VG vgdata lvm2 [50.00 GB / 0 free] PV /dev/sdc1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sdd1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sde1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sdf1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sdg ...

Tuning the nscd name cache daemon

I've been playing a bit with the nscd now and want to share some tips related to tuning the nscd.conf file. To see how the DNS cache is doing, use nscd -g. nscd configuration: 0 server debug level 26m 57s server runtime 5 current number of threads 32 maximum number of threads 0 number of times clients had to wait yes paranoia mode enabled 3600 restart internal passwd cache: no cache is enabled [other zero output removed] group cache: no cache is enabled [other zero output removed] hosts cache: yes cache is enabled yes cache is persistent yes cache is shared 211 suggested size 216064 total data pool size 1144 used data pool size 3600 seconds time to live for positive entries 20 seconds time to live for negative entries 66254 cache hi...
