Hey fellas. As you know from previous article, I’ve got the error around ASM block header. Which I also tried to solve with scrubbing mechanism which has appeared in 12c Oracle. You know this mechanism is working well, but only one’s you need to know, you must have at least one type of block (primary or mirror) in correct state, and then the scrubbing mechanism can afford to save your data. But not in my situation which I’ve described in previous article.
In a nut shell. I have two disk shelves with 15 disk by 4Tb each. And I want to create one big diskgroup which will have normal redundancy for database files, and backup files.
So I’ve created it. One diskgroup equal 60Tb size for database files, and backup files which will placed inside ADVM volume. And the problem has appeared only when I’ve tried to create backup through RMAN within one diskgroup. Again 🙂 If you will have TWO diskgroups, one for database files, and another with ADVM volume, and ACFS filesystem for backup files it would work well. But, if you will have ONE diskgroup for database files, and the same diskgroup for ADVM volume, and ACFS filesystem for backup files, you will stumble on the pitfall.
After couple weeks of investigations, and tests I’ve found the solution, which is easy. You just need to install Patch Set Update : 220.127.116.11.160119. In my environment I have this patches
