OPatch on AIX: Unhandled exception (Segmentation error)

One thing that you don’t want to see while performing an update of a database with the OPatch utility is a SEGFAULT. In my scenario, I simply wanted to list all the installed patches for an ORACLE_HOME and therefore issued opatch lsinventory:

$ cd $ORACLE_HOME/OPatch
$ ./opatch lsinventory
Oracle Interim Patch Installer version

Unhandled exception
Type=Segmentation error vmState=0x00060000

PuTTY customisation

One of the first things I do when I install PuTTY on a new machine, is to change the default color settings to something that is easier to read. This is a problem I have noticed on Red Hat machines, where the terminal color settings are not that great.

When you do an “ls” for example and the output contains folders, these are shown in a dark blue color, which makes it very hard to read on a black background. See the first picture in the gallery below.

BASH Setup in Solaris 10

Coming from Linux distributions where BASH is usually already set up and configured, I had to find my way around in a UNIX environment first. So here I present the files necessary for a proper installation of BASH under Solaris 10 (yes, I know Solaris 11 Express is out :)).

So after installing the BASH package (see my other post on setting up Solaris), you might find your new shell to be kinda boring. Also, it simply shows up as bash-3.00#, which by itself does not tell you a lot. So lets improve it a bit.

ZFS vs. Hardware RAID (RAID 10)

As I am currently fiddling around with Oracle Solaris and the related technologies, I wanted to see how the ZFS file system compares to a hardware RAID Controller. The ZFS file system allows you to configure different RAID levels such as RAID 0, 1, 10, 5, 6. In this post, I want to test the RAID 10 performance of ZFS against the performance with the HP RAID Controller (also in a RAID 10 configuration) over 4 disks.

First steps in Solaris 10

Although I already have some experience with Linux (Debian, Red Hat), the first steps with my brand new Solaris 10 installation turned out to be a little bit harder than expected. This was due to the minimalistic shell (SH) and problems while installing the SSH server. So here are my notes for those trying to get into Solaris. The first part includes the steps necessary to install the BASH shell. In the second part, installation of the SSH daemon is shown.

Setup: Solaris 10 Update 9, No remote services enabled, POSIX C locale, Core System Installation
