DBA in the Trenches

During the last upgrade I had to upgrade the database but also prepare the database for R12.2 so there were a few db patches that needed to be applied. Normally with two or three patches this is not a problem. However with twenty patches this makes things a bit more monotanous. My boss came to the rescue with this little jewel. First unzip ALL patches to $PATCH_TOP on DB tier unzip "p*.zip" -d $PATCH_TOP Add opatch to PATH in the $HOME/.bash_profile if not already in PATH export PATH=$PATH:$ORACLE_HOME/Opatch Check opatch is working opatch lsinventory  Apply all patches in a single command (one line) opatch napply -silent $PATCH_TOP -id 18485835,18689530,18893947,18966843,19291380,19393542,19472320,19627012,19649152,19779059,19835133,19896336,20093776,20177858,20181016,20204035,20294666,20476776,20830911,20994102,21091055 Now all I need is to figure out how to use this in non interactive mode so that I don't have to also answer the questions in between.

In accessing R12 applications, it throws the security warning message "The application's digital signature cannot be verified" In some of the client machine once this warning message pops-up, their IE session is getting hanged. Only option is to kill the session from task manager. This is creating problems with application users and hence provide us a solution to get rid of this warning message.  Solution Control panel > Java > Advanced > Security > Disable verification Reference:  Bug 11847386 : NEED TO SUPRESS R12 HANGING WARNING MESSAGE

Often I get a new server to clone an instance. This is the way I setup the user so that I don't have to do any change ownership to the files being cloned as they get the same id as the PROD system. This obviously will only work with single instances on a server. groupmod -g 500 dba useradd -gdba -s/bin/bash -poratest -d/home/oratest -m oratest usermod -u 500 oratest
