Getting rid of annoying, repetitive messages in /var/log/messages

The primary source of information regarding any change or issue on a linux system is the /var/log/messages file. I am often annoyed when a linux system is setup in such a way that certain messages are written to syslog with a high frequency swamping the messages file with information that is not important. The reason for my annoyance is that this makes it very hard to actually spot important information because you have to skip through a lot of lines before you find the important information, especially if you do not know for sure if there a message in the first place.

Please mind this blogpost is created on a Centos 7 server which uses rsyslog.

There are a couple of ways to manage this. The standard syslog way of managing this is the following, which can be found in /etc/rsyslog.conf:

Oracle Linux : Frequently Asked Questions (FAQs)…

I mentioned in a previous post that my company were planning to move all of our middle tier infrastructure and some of our Oracle databases to Oracle Linux running on a virtual infrastructure. That process is now underway.

Persuading the company to ditch Red Hat Enterprise Linux (RHEL) in favor of Oracle Linux took a bit of effort, partly due to some Fear, Uncertainty and Doubt (FUD) spread by one of the vendors we use. In the process of trying to counter the FUD I put together an Oracle Linux FAQ document. I thought it might come in handy for anyone else in a similar position, so I thought I would make it available on my site.

Oracle Linux 5 Update 7 Available…

Over the weekend Oracle Linux 5.7 was released, as noted here.

Upgrades follow the normal path. Do one of the following:

  • Boot from the DVD and upgrade that way.
  • Replace the “/etc/yum.repos.d/public-yum-el5.repo” file with the new version here, remembering to enable the appropriate entries.
  • Amend your existing “/etc/yum.repos.d/public-yum-el5.repo”, adding the following new entry.
    [ol5_u7_base]
    name=Oracle Linux $releasever - U7 - $basearch - base
    baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL5/7/base/$basearch/
    gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5
    gpgcheck=1
    enabled=1

If you picked either of the last two options, you can upgrade by issuing the “yum update” command when logged in as root.

I’ve upgraded a couple of VMs running Oracle and everything seems fine so far.

Cheers
