Hidden parameters in 10.2.0.4 database

edited Nov 21, 2012 4:37AM in Database Administration (MOSC) 5 commentsAnswered
Hello folks


We have inherited a 10.2.0.4 production database on Windows 2003 X64

There are 2 hidden parameters set in the database

1)    __awr_lush_threshold_metrics

2)    __db_block_cache_protect

 

We would like to know if there is any harm in these being there in the database?

Can we leave these 2 parameters as it or should we remove these from the spfile

We are thinking that since these are hidden parameters, theses must have been set as per oracle’s recommendation and removing these may cause some issues. But in the meantime we also wanted ot know if leaving these in the system wont lead to any problems

Howdy, Stranger!
