Clear archives or any other file using crontab

There are lots of logs created in a system and like cleaning the house over the weekend you also need to keep the system clean. Sometimes this can free up quite a bit of space in the storage. crontab is my preferred method of doing this sort of scheduled cleanup although it can be niggly at times.

# Minute  Hour    Day of Month   Month    Day of Week   Command
# (0-59)  (0-23)  (1-31)         (1-12)   (0-6)

30   11   *   *   6   find /u01/archive/*.dbf -mtime +7 -exec rm {} \;

So this means that I want the script to run once a week on a Saturday as 11:30 in the morning. It will find all the archives (*.dbf) that are older that 7 days and remove them. Really powerful so you also need to becareful how to use this command.
Great information of the power of crontab

Cancel or abort adop session

ADOP is in my opinion still pretty half baked. This is a critical tool that just isn't as intuitive as the old adpatch was. However we move with the times and get the hang of the new way of doing things. Along the way you might want to abort or cancel a patching cycling. With the two file systems and db editioning this can be a bit more to manage. I have learnt the hard way so you need to use the full cleanup after aborting a session.
adop phase=abort
adop phase=cleanup cleanup_mode=full

Cloning the instance I ran into this weird error. Was not sure what to do but after learning my lesson I dug through the error logs after seeing this in the adcfgclone log file.

Failed to initialize the application 'EBSDataSource' due to error weblogic.application.ModuleException after FNDCPASS apps change

Started testing password changes in our clone environments. Weblogic seems to love throwing you curve balls and when I changes the apps password with the below:
FNDCPASS apps/$APPS_PASS 0 Y system/system SYSTEM APPLSYS $APPS_PASS
I was not able to start the weblogic managed servers. A look in the log an I found this:
