Static DHCP IPs with KVM Virtualization

When building a virtualization lab system, I’ve found that I want static IPs assigned to my guests. You could just assign static IPs in the guest OS, but then you should document what IPs are in use for what hosts. It would be easier to just assign static IP entries in the DHCP server. There doesn’t seem to be a straight-forward way to get this done.

What I’ve found works is to destroy the network, edit it directly, and then restart it.

TSM Windows Client OS Level Demystified

The client OS level field in TSM for most operating systems is pretty straightforward. On Linux, it’s the kernel version, HP-UX and AIX show a recognizable OS level. For windows the OS level is more cryptic. Here is a list of the OS levels:

Operating System Client OS Level
Windows 95 4.00
Windows 98 4.10
Windows ME 4.90
Windows NT 4.0 4.00
Windows 2000 5.00
Windows XP 5.01
Windows Server 2003 5.02
Windows Vista 6.00
Windows Server 2008 6.00

CODBL0004W in IBM License Metric Tool

After installing the IBM License Metric Tool, you might see:
Essential periodic calculations did not occur when expected. The last day processed is Apr 25, 2011 while it should be Apr 29, 2011.

By default the tool processes the data collected 2 days prior, so you’ll see the specified dates are a few days old. IBM wants you to collect a bunch of data, and open a ticket, but you may be able to correct this yourself. In CODIF8140E Essential periodic calculations did not occur when expected IBM tells you that it’s probable that the TLMSRV user doesn’t have the correct privileges to the database, and to turn on debugging and send the logs to IBM. At the bottom of the page, it tells you what is actually needed:
Direct CREATETAB authority = YES 
Direct BINDADD authority = YES 
Direct CONNECT authority = YES

Encrypting A Default Username For

By default ILMT, and WebSphere in general, asks you for a password when running if security is enabled. That’s nice if you don’t trust your users. But, if you have a secured system you may not want to have to lookup the userid the once or twice a year you bring down WebSphere.

On a new install of ILMT, with the bundled WebSphere server, all you have to do is edit the soap.client.props file:

vi /opt/IBM/LMT/eWAS/profiles/AppSrv01/properties/soap.client.props
