FREQUENT RESIZE OF SGA
 
Applies to:
Oracle Server Enterprise Edition - Version: 10.2.0.1 to 11.1.0.7
This problem can occur on any platform.
Oracle Server - Enterprise Edition - Version: 10.2.0.1 to 11.1.0.7
10.2.X TO 11.1.0.6.0
 
Typically you will see a small spike in cursor: pin S wait on X or library cache lock waits.This can happen more often in OLTP envoriment.  shared pool and buffer cache is in demand.Problem will happen randomly and intermittently.
 
SELECT COMPONENT ,OPER_TYPE,FINAL_SIZE Final,to_char(start_time,'dd-mon hh24:mi:ss') STARTED FROM V$SGA_RESIZE_OPS;
 
V$SGA_RESIZE_OPS displays information about the last 800 completed SGA resize operations. 
This does not include in-progress operations.
 
select * from v$sgastat
where name = 'KGH: NO ACCESS';
 
KGH: NO ACCESS chunks are owned by the buffer cache and indicate
a partial transfer between buffer cache and shared pool.
