VMware Linux VM error “no valid devices were found”

Posted by: Andrei in Oracle

Note! this is applicable at least for OEL, RedHat, Fedora, but probably to all recent linux flavors.

oel5I had a strange error today when trying to install an Oracle Enterprise Linux 5 on a brand new VM made with VMware server 1.0.5:
When I tried to create linux partitions inside the VM, I’ve got: “no valid devices were found on which to create new filesystems“… like the kernel didn’t see the VM disks.

After less than a minute of google-ing this, I found that the “Typical” configuration inside the VMware Server is creating a SCSI disk with BusLogic controller which is not supported anymore by the Linux kernel.

To overcome this, you must create either a IDE disk either a SCSI disk with a LsiLogic controller.

Good luck!

Install Oracle Database Vault on patched 11g database (11.1.0.7) on Windows

Posted by: Andrei in Database, Oracle

oracle_11g_database1. Introduction
============
First, you need to make sure that you have enough space. As space was never a big concern for Oracle (but performance yes), make sure that you have at least 10 GB free disk space.
Second, make sure that you have the latest Windows SP and loopback adapter installed and configured if you are using DHCP. How? See this.

Download the latest 11g release (11.1.0.6 now) and don’t be scared about the size 🙂
If you have a Metalink account, you can also download the last update (11.1.0.7 now, patchset 6890831) and don’t be scared about the size 🙂
