Oracle 12c 初期化パラメータの確認方法

Posted at

Oracle 12cR2での、初期化パラメータの確認方法です。

sqlplusでDBに接続し、
v$parameterからSELECTすることで確認できます。

$ sqlplus user/passwd
SQL> SELECT name, value FROM v$parameter;

NAME                           VALUE
------------------------------ --------------------
lock_name_space
processes                      300
sessions                       472
timed_statistics               TRUE
timed_os_statistics            0
resource_limit                 TRUE
license_max_sessions           0
license_sessions_warning       0
long_module_action             TRUE
standby_db_preserve_states     NONE

「pool」を含むパラメータを検索したいなど、
特定の文字列を含むパラメータを検索する場合には、LIKE句を使います。

$ sqlplus user/passwd
SQL> SELECT name, value FROM v$parameter
  2  WHERE name LIKE '%pool%';

NAME                           VALUE
------------------------------ --------------------
shared_pool_size               0
large_pool_size                0
java_pool_size                 0
streams_pool_size              0
shared_pool_reserved_size      15309209
buffer_pool_keep
buffer_pool_recycle
olap_page_pool_size            0
