How do I monitor disk usage via munin?

If your system has munin installed, you may review historical disk usage using the web interface:

  • Launch your web browser
  • Browse to your server’s munin directory (where 192.168.1.100 is the IP address of your Linux server): http://192.168.1.100/munin
  • Select your system’s hostname to bring up the detailed monitoring page
  • Select Disk Usage in Percent to view storage utilization trends
Here’s an example screenshot of the output, showing storage usage over time:

How Do I Change the Time on a Linux Server?

The command date -s <date or time string> will set the system time and/or date. Where <date or time string> should be enclosed in double-quotes (“) and describe the date and/or time that you would like to set.

For example:
date -s “31 OCT 2011 13:55:00”
This command needs to be run as root in order for it to work.

Example to set just the time:
date +%T -s 07:54:00

You can also use the plain date command to display the current system date and time.
Note, you must restart the system admin in order the system time change to be reflected in Eclipse.

How do I disable Java heap dumps in AIX?

If your root or /tmp filesystem is filling with Heapdump* files, you may wish to disable the java dump functionality.

Open the /u2/eclipse/modules-conf/jboss.conf file and disable the dump options as shown in the example below:

JAVA_OPTS="-server -Dfile.encoding=ISO-8859-1 -Xdisablejavadump -Xdump:none -Xms1024m -Xmx1024m -XX:MaxPermSize=256m -XX:PermSize=256m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

How do I update my Eclipse credit card service to use the new TSYS domain?

Here are instructions for updating the URL with which your Vital/TSYS credit card service is configured to process transactions. This change is necessary for continued successful integrated credit card processing. After March 31st, 2012, Vital/TSYS is retiring the current domain. For more information, please refer to their bulletin on the subject.

The new domain, ssl1.tsysacquiring.net, is already available. You should adjust your credit card service to use the new domain using the directions below at any point prior to March 31, 2012 to avoid service disruption. If your network infrastructure limits connectivity to specific domains, you must update your network configuration to allow secure connectivity to the new domain.

If you no longer process credit card transactions integrated through Eclipse, or have migrated to the Element solution (or plan to do so before March 31, 2012), these instructions do not apply.

  • Log into the Windows server that runs the credit card service.
  • To open the appropriate configuration file for editing, click Start, select Run, and enter the following path: 
    "C:\Program Files\Eclipse\Eclipse Credit card authorization service\CCService.ini"
  • Change the “URL=” value to: 
    URL=ssl1.tsysacquiring.net/scripts/gateway.dll?Transact

  • Select File and Save before closing the text editor
  • To launch the Management Console’s Services control panel, click Start, select Run, and enter: 
    services.msc
  • Right-click on the Eclipse Credit Card Authorization Service, and select Restart.

 

If you have any questions or issues with these instructions, please enter a Service Request with our Systems team for assistance.

How do I run diagnostics on my Tandberg tape drive?
