I have a 10g R2 on AIX 5.3 with 4G (3800 M actual). I follow one note from Metalink to check the Library Cache Hit Ratio by this query
SELECT SUM(PINS) "EXECUTIONS", SUM(RELOADS) "CACHE MISSES WHILE EXECUTING"
FROM V$LIBRARYCACHE;
and the ratio during the busy hours is around 1.36%. According to the doc, I need to increase the shared_pool_size. How can I achieve that if the system is using the ASMM and my sga_max_size is 1408 and without stop/restart the system? does that mean I need to increase the sga max so ASMM can allocate more to shared_pool? that will cause more in OS swapping ?
