Hi,
When we want to gather schema statistics which method we should follow and why ?
Please advice.
exec dbms_utility.compile_schema('SHIKHAR');
or
BEGIN
SYS.DBMS_STATS.GATHER_SCHEMA_STATS (
OwnName => 'JACK'
,Granularity => 'DEFAULT'
,Options => 'GATHER'
,Gather_Temp => FALSE
,Estimate_Percent => SYS.DBMS_STATS.AUTO_SAMPLE_SIZE
,Method_Opt => 'FOR ALL COLUMNS SIZE AUTO '
,Degree => 4
,Cascade => TRUE
,No_Invalidate => FALSE);
END;
/
Regards,

My analogy was not correct.
compile_schema compile the objects
gather_statistics gathers statistics
They cannot be compared, they do completly different things. It is like comparing network and CPU.
