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

Launching a Concurrent with Form Personalization on EBS 11i

There are two methods when it comes to running a concurrent from a Form Personalization in Oracle. The thing you need to do in either case is create a menu option for the form in question. This is generally done on a WHEN-NEW-FORM-INSTANCE Trigger Event. If you already have an event like this then you can add it there. I personally like to group my customizations together so there is not much overlap. Whichever catches your fancy will work. Setup the menu with the name: You now have a menu item for the launching of the concurrent program. This is where the two methods separate and you may choose which ever is more appropriate to you. Launch FNDRSRUN (Submit Request) This will use the zoom feature of Oracle Form Personalization to open the Submit Request Form, and pass the parameters to it. This involves personalization in two forms. The sending form needs to call the Form Function and pass the parameters and the Submit Request form needs to receive and process those parameters....

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.
