Hi ,
I have a SqlServer 2008 r2 under DPA
in the RESOURCE TAB
DPA give me an ALERT about Procedure Cache Hit Ratio
Lookin on on online help i 've seen :
Percentage of time when SQL
Server looks for an execution plan in the procedure cache and finds it for this instance.
If this is low, try to write more reusable code and/or consider increasing the size of the
procedure cache
To see current metrics for
the procedure cache, run the query:
select * from
master..sysperfinfo where object_name like '%Plan
Cache%';
But i cant' t find how increase this value , it seems is an automatic parameter
