some quick linux tips and tricks

in playing with our new library system, I got distracted by questions from customers. This did side track me as well as attending the Spatial Users Group in San Antonio. Spatial is an interesting technology that looks like it will be fun to play with. Unfortunately, I don’t see how to integrate it into a library checkout demo since we are just starting with one library.

A couple of simple notes for myself…..

to list Oracle packages on a Linux box………. rpm -qa | grep -i oracle
to remove a package on a Linux box ………… rpm -e oracle-xe-10.2.0.1-1.0

these are simple examples on how to find and remove the XE version of the database so that we can add more.

to mount a usb disk on my windows laptop/desktop

1) share the disk from windows
2) on the hosted linux box, make sure I can see the ipaddress of my laptop. This might require to reconfigure the network and edit host entries.
3) mkdir /mnt/f
4) mount -t smbfs //my-laptop/f  /mnt/f

This allows me to look at the CD and DVD images of our software, the Linux ISOs, and tutorials/documents associated with the installations.

When removing software from a vmware image, the size of the disk and disk partitions that have been created and populated does not shrink. For example, if we install 2G of software on top of the 1.5G OS installation, the vmware image will be 3.5G in size. If we delete the 2G of software, the vmware image does not shrink.
