OCR Backups Filling Up CRS_HOME Space

While checking my OCR backup I wondered why Oracle keep creating OCR backup without deleting the old ones. Should I delete them by my own?.. it sounds unkind!!.

I start searching on Google and metaling.. Guess what??? It’s a BUG.

That simply means, if you have dozens of OCR backups you may facing the same bug. Since the OCR backups should consist of 7 files as follow:

#ls -ltr u02/app/11.2.0/grid/cdata/feco-cluster/day* week* backup0*

-rw-------    1 root     system      7028736 May 22 2011  backup02.ocr

-rw-------    1 root     system      7028736 May 22 2011  backup01.ocr

-rw-------    1 root     system      7028736 May 22 2011  backup00.ocr

-rw-------    1 root     system      6979584 May 22 2011  week.ocr

-rw-------    1 root     system      7028736 May 22 2011  day_.ocr

-rw-------    1 root     system      7028736 May 22 2011  day.ocr

presenting the result of :

# ./ocrconfig -showbackup auto

feco04     2014/05/24 12:31:09     /u02/app/11.2.0/grid/cdata/feco-cluster/backup00.ocr

feco04     2014/05/24 08:31:07     /u02/app/11.2.0/grid/cdata/feco-cluster/backup01.ocr

feco04     2014/05/24 04:31:06     /u02/app/11.2.0/grid/cdata/feco-cluster/backup02.ocr

feco04     2014/05/23 04:31:00     /u02/app/11.2.0/grid/cdata/feco-cluster/day.ocr

feco04     2014/05/14 04:29:51     /u02/app/11.2.0/grid/cdata/feco-cluster/week.ocr

My current ocr backup look like:

-rw-------    1 root     system      7221248 Jun 24 2013  13458777.ocr

-rw-------    1 root     system      7221248 Jun 24 2013  14872007.ocr

-rw-------    1 root     system      7221248 Jun 24 2013  28713517.ocr

-rw-------    1 root     system      7221248 Jun 25 2013  39937824.ocr

-rw-------    1 root     system      7221248 Jun 25 2013  56169871.ocr

-rw-------    1 root     system      7221248 Jun 25 2013  58569011.ocr

-rw-------    1 root     system      7221248 Jun 27 2013  21069301.ocr

-rw-------    1 root     system      7221248 Jun 27 2013  11741111.ocr

-rw-------    1 root     system      7221248 Jun 27 2013  29616835.ocr

-rw-------    1 root     system      7221248 Jun 27 2013  19887106.ocr

-rw-------    1 root     system      7221248 Jun 28 2013  27246017.ocr

And crsd.log showing this error:

OCRSRV][9521]Failure in renaming file [/u02/app/11.2.0/grid/cdata/feco-cluster/25677603.ocr] to [/u02/app/11.2.0/grid/cdata/feco-cluster/backup00.ocr]

How to solve that???

According to (Doc ID 1191067.1) "change all 7 automatic backup files to be owned  by root:root with permission "-rw-------""

The current privilege of the 7 files are:

-rw-r--r--    1 grid     oinstall      7028736 May 22 2011  backup02.ocr

-rw-r--r--    1 grid     oinstall      7028736 May 22 2011  backup01.ocr

-rw-r--r--    1 grid     oinstall      7028736 May 22 2011  backup00.ocr

-rw-r--r--    1 grid     oinstall      6979584 May 22 2011  week.ocr

-rw-r--r--    1 grid     oinstall      7028736 May 22 2011  day_.ocr

-rw-r--r--    1 grid     oinstall      7028736 May 22 2011  day.ocr 

Just change them to:

chown root:system week*

chown root:system day*

chown root:system backup0*

chmod 600 week*

chmod 600 day*

chmod 600 backup0*
