When ASM rebalancing stops...!!!!
Was adding disks to ASM diskgroups few days back as a part of weekly space addition. Added one disk to each of the ASM diskgorup (CDBP and CDBP2). The disk space got reflected in both the diskgroups, but lot of interesting things were waiting for me. I was able to use space the space in CDBP2 diskgroup for tablespaces but CDBP diskgroup space got jammed…., [...]

Reducing Downtime during database movement and migrations
There are lot of strategies possible for moving a database from one server to another. The things are to be planned in a much better way when we have to do multiple things in a single window.

root.sh - Oracle CRS stack is already configured and will be running under init(1M)
Recently got an issue in RAC when i lost my voting disk...No mirroring ..No backups..Why? It was a test environment...The only solution to recover was to reinstall the clusterware and then register the resources.
I did a cleanup as per metalink note 239998.1 (How to Clean Up After a Failed Oracle Clusterware (CRS) Installation) for Linux. Everything went smooth until the installation prompted for root.sh execution.
[root@rac1 crs]# mv /etc/oracle/ocr.loc /etc/oracle/ocr.loc.old
[root@rac1 crs]# ./root.sh

oops....!!!!
Thought i forgot to do cleanup of ocr and voting disk raw devices, although this was not case...I did zeroing of ocr and voting disk rawdevices again...and tried again..no luck...!!!!
Again checked the metalink note...and realised that i forgot to delete /etc/oracle/ocr.loc. This is file which is created by root.sh and since it was already present, so root.sh was failing.
Removed the file and it worked...Same thing was done for 2nd node of RAC before running root.sh
