PERC H800 in non-Dell PowerEdge system

Posted 08-22-2016 at 10:31 AM by MensaWater

We had a PERC H800 MegaRaid adapter in one of our Dell PowerEdge R910 systems. We had a Dell MD1220 array attached to that.

We bought a new SuperMicro based system and initially put the PERC H800 in this server in the top slot of the middle riser. It was dead as a door nail there. Original documentation for the PERC H800 indicated it only worked in certain Dell PowerEdge models so I didn't know if it should work in this new system.

I came across this thread discussing...

Migrating SAN storage from RHEL 5.9 to RHEL 6.8

Posted 07-25-2016 at 01:12 PM by MensaWater

I've had to migrate multiple Oracle instances from RHEL 5.9 to RHEL 6.8 because we're replacing an old server. This is Oracle 11gR2 using ext4 filesystems (not RAC/GRID, not using ASM).

Just wanted to share the steps. Presumably this would work for most (Redhat derived at least including CentOS and Fedora) Linux flavors so I only specify the source and target distro/versions for completeness.

We use a Hitachi VSP disk array and with full fiber...

RHEL5 won't support TLSv1.1 or higher

Posted 03-19-2016 at 10:59 AM by MensaWater
Updated 09-06-2016 at 04:00 PM by MensaWater (Adding note about ciphers)

We found the version of curl provided for RHEL5 does not include the flags "--tlsv1.1" or "--tlsv1.2" provided by later versions of curl.

This means CentOS5 curl does not include/support the flags "--tlsv1.1" or "--tlsv1.2".

RHEL7 and RHEL6 versions do support TLSv1.1 and TLSv1.2 and work when using them. One might need to run yum update for curl and/or openssl to have the versions with the support. On my RHEL6 systems I had...

It runs from command line but not from cron or init script

This question has been posted many times over the years both here at LQ and other sites. Accordingly I'm making this a blog post in the hopes people will find it useful.

When one run things at command line they inherit the environment of the user running them as set by things such as /etc/profile, $HOME/.bashrc, $HOME/.profile and/or $HOME/.bash_profile.

There are many environment variables that can impact a script. You can see all the environment variables you...

CLI to get Oracle Supply Network email attachments

Posted 10-06-2015 at 03:37 PM by MensaWater
Updated 11-12-2015 at 08:05 AM by MensaWater

I'm writing this up because I've often seen the question "How do I extract email attachments at command line?". I had to figure out how to use various tools to do this recently and figured I'd share what I did.

EDIT 11-Nov-2015:
While what is written below certainly works for extracting email attachments including those sent by OSN it turns out Oracle does NOT include all fields in the email they send so we ultimately abandoned this setup for OSN and are instead...
