ssh Authorized Setup

If you want to run scripts from one server to the next or possibly a central server where you run clones and backups from you'll want to authorize the server on each of the servers you wan tto connect to.

First thing you need to do is generate a public and private key. Remember to keep the password black, I also use the defaults as you can see below.
ssh-keygen

Using ssh copy keys to target server or a shared directory like below that all the environments see
cp $HOME/.ssh/id_rsa.pub /nfs_share/tmp/id_rsa.pub

Check if the ssh directory exists on the target server, if not create it
mkdir -p ~/.ssh
touch ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys


Copy the public keys into the authorized_keys
cat /nfs_share/tmp/id_rsa.pub >> ~/.ssh/authorized_keys

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

Creating new WLS domain ends with exit code 255

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.

Error during rapid clone on pasteBinary.sh, exit code 255

I needed to run a clone and was running into a really head scratcher. As is Oracle\'s way they sometimes enjoy giving us DBA's a bit of detective work to do. As usual I kept knocking my head into various brick walls instead of tracking back through the logs. Eventually I came up with the problem Start to configure the run filesystem. You can do a dualfs from AD-TXK Delta 7 but for now I just needed to get this up and running: perl adcfgclone.pl appsTier START: Creating FMW Home.
