The values of initialization parameters in another session can be changed using procedures SET_BOOL_PARAM_IN_SESSION and SET_INT_PARAM_IN_SESSION provided in DBMS_SYSTEM package.
Let’s demonstrate:
SQL>conn / as sysdba
SYS> grant dba to hr;
– Currently parameter HASH_AREA_SIZE is set to 131073 in HR session
HR>> sho parameter hash_area_size
NAME TYPE VALUE
———————————— ———– ——————————
hash_area_size integer 131073
– Find out SID, SERIAL# for HR session
SYS> select sid, serial#, username from v$session where username=’HR’;
SID SERIAL# USERNAME
———- ———- ——————————
54 313 HR
– Set value of parameter HASH_AREA_SIZE to 131072 in HR session
SYS> exec dbms_system.SET_INT_PARAM_IN_SESSION(54, 313, ‘HASH_AREA_SIZE’,131072);
– Verify that the value of parameter HASH_AREA_SIZE has been changed in HR session
HR> sho parameter hash_area_size
NAME TYPE VALUE
———————————— ———– ——————————
hash_area_size integer 131072
Similary Boolean initialization parameters can be modified using dbms_system.SET_BOOL_PARAM_IN_SESSION.
– Let’s find out the value of parameter SKIP_UNUSABLE_INDEXES in HR session
HR> sho parameter skip_unusable indexes
NAME TYPE VALUE
———————————— ———– ——————————
skip_unusable_indexes boolean TRUE
– Modify the value of parameter SKIP_UNUSABLE_INDEXES to FALSE in HR session
SYS> exec dbms_system.SET_BOOL_PARAM_IN_SESSION(54, 313, ‘skip_unusable_indexes’,FALSE);
– Verify that the value of parameter SKIP_UNUSABLE_INDEXES has been changed to FALSE in HR session
HR> sho parameter skip_unusable indexes
NAME TYPE VALUE
———————————— ———– ——————————
skip_unusable_indexes boolean FALSE
