Finding and deleting old log files

Occassionally you need to clean up some disk space. The quickest and easiest thing to do is often to look for log files that have been rolled by some other process.

For Example:

find . -name *.log.5 -exec /bin/rm '{}' \;

Of course, you need to understand the naming convention of your logs.  Here's a quick example of finding and removing files with a date appended to the original log name.  This command will remove all the log files for the first 9 days of August 2011.

find . -name *.log.2011-08-0* -exec /bin/rm '{}' \;

Jython Snippet - Max Heap or All appServers on Node XYZ

myNode='mw-node-001'
serverList = AdminServerManagement.listServers("",myNode)
for server in serverList:
   serverName=AdminConfig.showAttribute(server,'name')
   maxHeapL=AdminServerManagement.listJVMProperties(myNode,serverName,'maximumHeapSize')
   maxHeap=str(maxHeapL)
   print serverName + " " + maxHeap

Complete Idiot's Guide To Jython for Noob Dummies

It's been a long time since I have jython'ed.  Here's a tip...

if you try something like this:

cntr=1
print "counter is " +cntr

you're going to get an error similar to:

TypeError: __add__ nor __radd__ defined for these operands

So how do you do this?  It's almost too easy:

cntr=1
print "counter is " +cntr.toString()
