LMHB (ospid: XXXX): terminating the instance due to error 29770

If you get ” LMHB (ospid: XXXX): terminating the instance due to error 29770 ” error, probably your instance is restarted automatically and I have seen this error on Exadata X7-2 Full Rack.
This Issue is due to Bug 22806698 : GCW1AP CRASH – ORA-29770 LMHB TERMINATES INSTANCE

 

_lm_enable_aff_benefit_stats

To solve this error, you should set the value of the parameter “_lm_enable_aff_benefit_stats” to FALSE in the database.

 

alter system set “_lm_enable_aff_benefit_stats”=FALSE scope=both sid=’*’;

 

 

Or you can apply patch 22806698 for the Bug 22806698 : GCW1AP CRASH – ORA-29770 LMHB TERMINATES INSTANCE

 

 

== OR ==

 

Apply the Bundle Patches where Bug fix included. Please refer following MOS Note:

Bug 22806698 – ORA-29770 due to default value for _lm_enable_aff_benefit_stats (Doc ID 22806698.8)
