Hi All,

My Oracle version is 11.2.0.4 64 Bit

And Linux version is : SUSE Linux Enterprise Server 11 SP3  (x86_64).

Memory utilization in the server is too high.

Memory setting in the oracle is :

SQL> select decode(pool,null,name,pool),round(sum(bytes)/1024/1024,4) MB from v$sgastat group by decode(pool,null,name,pool) order by 2 desc;

DECODE(POOL,NULL,NAME,POOL         MB

-------------------------- ----------

buffer_cache                    15360

shared pool                     13952

java pool                         448

log_buffer                    56.9688

fixed_sga                      2.1634

Please suggest if the memory needs to be increased and also i can see dynamic memory management is not enable in the server.

SQL> show parameter sga_target

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

sga_target                           big integer 0

SQL> show parameter memory_target

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

memory_target                        big integer 0

SQL>

SQL> show parameter sga_max_size

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

sga_max_size                         big integer 29952M

SQL>

Please suggest.

Thanks before you act.

Regards

Monoj
