After the upgrade from vCenter 5.1 GA to release 5.1.0b and moving vCenter to a new server we had a small issue with the vCenter database agent jobs, as we had this error:
Could not find stored procedure 'purge_stat1_proc'. [SQLSTATE 42000] (Error 2812). The step failed.
This caused me to look a little bit more into the database agent jobs.

AIX Reading Passwords
Summary: ALthough AIX is by now on version 7.3 I find these old pages so fascinating I decided to keep them. On this page I'll show you quickly hide passwords from the screen. This page is for AIX 5.3 and AIX 6.1.
Date: Between 2010-2013
Refactor: 21 December 2024: Checked formatting.
If you have a script which requires a password somewhere as input and you don't want to have that password displayed on the screen, this is how you do it:
# Request for the password of the ORACLE_USER printf "Provide password %s user: " $ORACLE_USER # Save the current settings of the terminal session stty_orig=`stty -g` # Change the terminal session settings so it won't display input anymore stty -echo # Read the input from the script operator read ora_secret # Set the terminal back to it's old settings stty $stty_orig
