Data Guard and Oracle Restart, aka relink always !!!

During my early years with PC I love to play "Leisure Suit Larry" (especially part 1 to 3 which has running on CGA or Hercules graphics card). Author of this games, Al Lowe had a good sense of humor and every time you failed your mission or stuck in a place - there was an pop up on the screen "Al says: save early, save often". After today fight with Oracle I should remember a next saying - "Relink after, relink always".

Let me explain what what happen today.

UKOUG post conference geek update part 1 – ACFS for Oracle databases

One of the many interesting things I heard at the conference this time around was that Oracle’s future direction includes the use of database files on ACFS. When ACFS came out this was strictly ruled out, but has been possible for a little while now, I believe with 12.1.0.1.0. With the Oracle Database Appliance (ODA) using this deployment option and hearing about it at the conference, a little further investigation was in order. During one of the presentation @OracleRACPM Markus Michalewicz had a reference to a script that I didn’t know on his slides. The script is called gDBClone, and I wanted to see how it works. The idea is that the script can be used to create a snap-clone of a database if the source is on ACFS and in archivelog mode.

As it turned out there were a few hurdles along the way and I will point them out so you don’t run into the same issues.
