大家好，这里是 DBA 学习之路，专注于提升数据库运维效率。

目录

前言

最近有朋友问，如何查看 Oracle 数据库当前安装了哪些功能组件，以及这些功能的特性是否被实际使用了？乍一听，这个问题不简单。于是我在 MOS 上查找了一些资料，整理出一套完整的方法，希望对大家有所帮助。

作为DBA，您是否遇到过这些困惑：

  • 数据库安装了哪些功能组件？
  • 这些组件是否真的被业务使用？
  • 如何避免为未使用的功能支付不必要的许可证费用？

本文将带您全面掌握 Oracle 功能组件的检查方法，助你实现：

  • ✅ 精准掌握组件安装状态
  • ✅ 深度分析功能使用情况
  • ✅ 合规规避许可证风险
  • ✅ 优化数据库性能配置

这些方法可以帮助 DBA 全面了解 Oracle 数据库中功能组件的安装及使用情况，尤其在许可证合规性检查中非常有用。

数据库版本确认

检查数据库版本：

SQL> select banner from v$version;

BANNER
--------------------------------------------------------------------------------
Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production

企业版与标准版功能差异显著，建议先确认版本：

  • 企业版：包含全部高级功能（OLAP、Data Guard 等）
  • 标准版：功能受限（无分区表、高级压缩等）

📌 官方文档参考：Database Licensing Information

组件安装状态检查

查看已安装组件

可以通过 DBA_REGISTRY 视图查看当前数据库中已安装的功能组件：

  • VALID：组件已安装且正常；
  • INVALID：组件异常需修复；
  • OPTION OFF：组件已禁用；

参考如下查询结果：

COL comp_id FORMAT A12
COL version FORMAT A10
COL comp_name FORMAT A40
COL status FORMAT A10
SET pages 30
SELECT SUBSTR(comp_id,1,12) AS comp_id,
       status,
       SUBSTR(version,1,10) AS version,
       SUBSTR(comp_name,1,40) AS comp_name
FROM dba_registry
ORDER BY 1, 2;

COMP_ID      STATUS     VERSION    COMP_NAME
------------ ---------- ---------- ----------------------------------------
APS          VALID      19.0.0.0.0 OLAP Analytic Workspace
CATALOG      VALID      19.0.0.0.0 Oracle Database Catalog Views
CATJAVA      VALID      19.0.0.0.0 Oracle Database Java Packages
CATPROC      VALID      19.0.0.0.0 Oracle Database Packages and Types
CONTEXT      VALID      19.0.0.0.0 Oracle Text
DV           VALID      19.0.0.0.0 Oracle Database Vault
JAVAVM       VALID      19.0.0.0.0 JServer JAVA Virtual Machine
OLS          VALID      19.0.0.0.0 Oracle Label Security
ORDIM        VALID      19.0.0.0.0 Oracle Multimedia
OWM          VALID      19.0.0.0.0 Oracle Workspace Manager
RAC          OPTION OFF 19.0.0.0.0 Oracle Real Application Clusters
SDO          VALID      19.0.0.0.0 Spatial
XDB          VALID      19.0.0.0.0 Oracle XML Database
XML          VALID      19.0.0.0.0 Oracle XDK
XOQ          VALID      19.0.0.0.0 Oracle OLAP API

这些组件是在数据库安装之初进行选择安装的，无法禁用，与是否使用也无关，非必要情况下也不建议去卸载。

功能使用情况监控

DBA_FEATURE_USAGE_STATISTICS

DBA_FEATURE_USAGE_STATISTICS 是 Oracle 提供的关键数据字典视图，用于跟踪数据库功能使用情况（从数据库上次启动开始，每 7 天采样一次），非常适用于许可证合规性管理和容量规划。

一键查看当前已启用特性：

SQL> ALTER SESSION SET nls_date_format = 'dd-mon-yy hh24:mi:ss';
SET lines 2222 pages 1000
COL name FOR a60
COL currently_used FOR a5
COL last_usage_date FOR a20

SELECT name, currently_used, last_usage_date, description
FROM dba_feature_usage_statistics
WHERE currently_used = 'TRUE';

这个视图的数据更新机制如下：

  • 自动采样：由 MMON 进程每周自动采样；
  • 手动刷新：可调用 DBMS_FEATURE_USAGE_INTERNAL 包进行强制刷新；
  • 数据保留：一般保留约一年；
  • 注意延迟：新启用的功能可能需要数日才会出现在视图中；

MMON 的采样机制解析

可通过以下方式 Trace MMON 的行为，深入了解 Oracle 的采样逻辑：

SQL> BEGIN
  dbms_monitor.serv_mod_act_trace_enable(
    service_name => 'SYS$BACKGROUND',
    module_name  => 'MMON_SLAVE',
    action_name  => 'Auto-DBFUS Action');
END;
/

SQL> ALTER SESSION SET "_swrf_test_action" = 28;

SQL> ALTER SESSION SET EVENTS 'immediate trace name mmon_test level 6';

然后通过命令提取 trace 文件中的 SQL：

grep -A 1 "sqlid='" $ORACLE_BASE/diag/rdbms/<db_name>/<instance>/trace/<file>.trc | grep -v "sqlid='"

Trace 中会显示大量底层采样 SQL，例如：

SELECT name, inst_chk_method, inst_chk_logic, usg_det_method, usg_det_logic
FROM wri$_dbu_feature_metadata mt, wri$_dbu_feature_usage fu
WHERE mt.name = fu.name
  AND fu.dbid = :dbid
  AND fu.version = :version;

通过这些采样 SQL，Oracle 能够自动判断哪些功能被使用，例如：

  • Data Guard 是否启用
  • 是否使用 SecureFiles
  • 是否进行过表恢复、跨平台迁移等 RMAN 操作
  • 分区表是否存在
  • 是否使用并行执行、Adaptive Plan 等

上述这些组件的收费情况可以参考文章：

Oracle授权如何购买？多少钱？如何计算？

比如其中部分功能特性的收费情况：

大家可以根据自己的数据库版本以及功能特性使用情况，完全可以大致预估出来费用了。

组件使用分析

很多人关心数据库组件的使用情况，通过上述方式可能无法精确查询，针对这个问题，我也整理了一些检查组件是否被使用的方法。

Oracle Text

检查当前数据库是否使用 Text 组件：

SQL> SET pages 999 lines 120 trimout ON trimspool ON
COL objdep format a55 hea "Object Name (Type)"
COL refr format a35 hea "Object Reference (Type)"

SELECT OWNER||'.'||name||' ('||decode(TYPE, 'MATERIALIZED VIEW', 'MV', 'DIMENSION', 'DIM', 'EVALUATION CONTXT', 'EVALCTXT', 'PACKAGE BODY', 'PKGBDY', 'CUBE.DIMENSION', 'CUBE.DIM', TYPE)||')' objdep,
       referenced_owner||'.'||referenced_name||' ('||decode(referenced_type, 'EVALUATION CONTXT', 'EVALCTXT', 'NON-EXISTENT CONTXT', 'NO-EXIST', 'PACKAGE BODY', 'PKGBDY', 'CUBE.DIMENSION', 'CUBE.DIM', referenced_type)||')' refr
FROM dba_dependencies
WHERE referenced_OWNER ='CTXSYS'
  AND OWNER NOT IN ('PUBLIC', 'CTXSYS', 'SYS')
ORDER BY 1;

如果需要卸载 Oracle Text，可以参考下方步骤：

conn / as sysdba
@?/ctx/admin/catnoctx.sql
drop procedure sys.validate_context;

Oracle Workspace Manager

检查当前数据库是否使用 Workspace Manager：

SQL> REM srdc_owm_usage.sql - collect Oracle Workspace Manager usage
define SRDCNAME='OWM_USAGE'
SET MARKUP HTML ON PREFORMAT ON
set TERMOUT off FEEDBACK off VERIFY off TRIMSPOOL on HEADING off
COLUMN SRDCSPOOLNAME NOPRINT NEW_VALUE SRDCSPOOLNAME
select 'SRDC_'||upper('&&SRDCNAME')||'_'||upper(instance_name)||'_'||
        to_char(sysdate,'YYYYMMDD_HH24MISS') SRDCSPOOLNAME from v$instance;
set TERMOUT on MARKUP html preformat on
REM
spool &&SRDCSPOOLNAME..htm
select '+----------------------------------------------------+' from dual
union all
select '| Diagnostic-Name: '||'&&SRDCNAME' from dual
union all
select '| Timestamp:       '||
        to_char(systimestamp,'YYYY-MM-DD HH24:MI:SS TZH:TZM') from dual
union all
select '| Machine:         '||host_name from v$instance
union all
select '| Version:         '||version from v$instance
union all
select '| DBName:          '||name from v$database
union all
select '| Instance:        '||instance_name from v$instance
union all
select '+----------------------------------------------------+' from dual
/
set HEADING on MARKUP html preformat off
REM === -- end of standard header -- ===
select comp_name,version,status from dba_registry where comp_id = 'OWM' ;
select table_name,owner,state from DBA_WM_VERSIONED_TABLES;

select workspace, parent_workspace, owner, freeze_status, resolve_status  from dba_workspaces;
select version, parent_version, workspace from ALL_VERSION_HVIEW;
spool off;
exit

执行结果：

如果是安装未使用则显示以上结果。

卸载 Workspace Manager 组件：

-- sys 用户执行
SQL> @$ORACLE_HOME/rdbms/admin/owmuinst.plb

Spatial

检查当前数据库是否使用 Spatial：

SQL> col owner format a12
col table_name format a35
col column_name format a25
select owner, table_name, column_name
from dba_tab_columns
where data_type = 'SDO_GEOMETRY'
and owner != 'MDSYS';

no rows selected

如果数据库中不存在包含 SDO_GEOMETRY 列的表，则表示该数据库未使用 Spatial 功能。

卸载 Spatial 的步骤如下：

conn / as sysdba

-- 检查组件是否被使用
set pages 200
col owner for a20
col table_name for a30
col column_name for a25
select owner, table_name, column_name
from dba_tab_columns
where data_type = 'SDO_GEOMETRY'
and owner != 'MDSYS'
order by 1,2,3;

-- 如果被使用，则需要先清理对象
-- drop Spatial indexes
set pagesize 0
spool DropIndexes.sql
select 'drop index ' || owner || '.' || index_name ||';'
from dba_indexes where ityp_name = 'SPATIAL_INDEX';
spool off

@DropIndexes.sql

-- drop Spatial tables
set pagesize 0
spool DropTables.sql
select 'drop table '|| owner ||'.'|| table_name||';'
from dba_tab_columns
where data_type = 'SDO_GEOMETRY'
and owner != 'MDSYS';
spool off

@DropTables.sql

-- 清空回收站
purge dba_recyclebin;

-- remove Semantic support
@?/md/admin/semremov.sql

-- drop MDSYS user
drop user MDSYS cascade;

-- 一键卸载(多租户环境下也可以)，oracle 用户下执行，不在 sqlplus 执行：
[oracle@emcc:/home/oracle]$ $ORACLE_HOME/perl/bin/perl $ORACLE_HOME/rdbms/admin/catcon.pl -e -u SYS -r -b SDO_deinst -d $ORACLE_HOME/md/admin deinssdo.sql
catcon::set_log_file_base_path: ALL catcon-related output will be written to [/home/oracle/SDO_deinst_catcon_2719568.lst]

catcon::set_log_file_base_path: catcon: See [/home/oracle/SDO_deinst*.log] files for output generated by scripts

catcon::set_log_file_base_path: catcon: See [/home/oracle/SDO_deinst_*.lst] files for spool files, if any

Enter Password: 
catcon.pl: completed successfully

-- drop all remaining public synonyms created for Spatial
set pagesize 0
set feed off lines 120 trimout on trimspool on
spool dropsyn.sql
select 'drop public synonym "' || synonym_name || '";' from dba_synonyms where table_owner='MDSYS';
spool off;
@dropsyn.sql

-- drop related user
drop user mddata cascade;
-- Only created as of release 11g:
drop user spatial_csw_admin_usr cascade;
drop user spatial_wfs_admin_usr cascade;

IMPORTANT NOTE: Spatial will still appear in V$OPTION but this is expected behavior as explained in Note:273573.1 - Removed Spatial Option But Spatial Still Appears In V$Option

XML Database (XDB)

检查当前数据库是否使用 XDB：

SQL> define SRDCNAME='XDB_USAGE_CHECK'
set pagesize 200 verify off sqlprompt "" term off entmap off echo off
set markup html on spool on
COLUMN SRDCSPOOLNAME NOPRINT NEW_VALUE SRDCSPOOLNAME
select 'SRDC_'||upper('&&SRDCNAME')||'_'||upper(instance_name)||'_'||
       to_char(sysdate,'YYYYMMDD_HH24MISS') SRDCSPOOLNAME from v$instance;
spool &&SRDCSPOOLNAME..htm
select 'Diagnostic-Name: ' || '&&SRDCNAME'  as "SRDC COLLECTION HEADER"  from dual
union all
select 'Time: ' || to_char(systimestamp, 'YYYY-MM-DD HH24MISS TZHTZM' ) from dual
union all
select 'Machine: ' || host_name from v$instance
union all
select 'Version: '|| version from v$instance
union all
select 'DBName: '||name from v$database
union all
select 'Instance: '||instance_name from v$instance
/
set serveroutput on
alter session set nls_date_format = 'DD-MON-YYYY HH24:MI:SS'

从 Oracle 12.1 版本开始，XDB 组件已经无法卸载，是必备组件。

OLAP

检查当前数据库是否使用 OLAP：

SQL> select VALUE from v$OPTION where PARAMETER = 'OLAP';

VALUE
----------------------------------------------------------------
TRUE

SQL> col owner format a10

SQL> col aw_name format a20

SQL> select owner, aw_name from dba_aws;

OWNER                AW_NAME
-------------------- ------------------------------
SYS                  AWREPORT
SYS                  AWXML
SYS                  AWMD
SYS                  AWCREATE10G
SYS                  EXPRESS
SYS                  AWCREATE

如果都是 SYS 用户的对象，就说明没有使用 OLAP 组件。

卸载 OLAP：

[oracle@emcc:/home/oracle]$ chopt disable olap

Writing to /u01/app/oracle/product/19.3.0/db/install/disable_olap_2025-06-04_16-11-48PM.log...
/usr/bin/make -f /u01/app/oracle/product/19.3.0/db/rdbms/lib/ins_rdbms.mk olap_off ORACLE_HOME=/u01/app/oracle/product/19.3.0/db
/usr/bin/make -f /u01/app/oracle/product/19.3.0/db/rdbms/lib/ins_rdbms.mk ioracle ORACLE_HOME=/u01/app/oracle/product/19.3.0/db

删除 OLAPSYS 用户：

SQL> drop user OLAPSYS cascade;
@?/rdbms/admin/utlrp.sql

OJVM

检查当前数据库是否使用 OJVM：

SQL> SELECT version, status FROM dba_registry WHERE comp_id='JAVAVM';

VERSION                        STATUS
------------------------------ --------------------------------------------
19.0.0.0.0                     VALID

SQL> select * from gv$java_patching_status;

no rows selected

SQL> select count(*) from x$kglob where KGLOBTYP = 29 OR KGLOBTYP = 56;

  COUNT(*)
----------
      1313

SQL> select inst_id, name, con_id from gv$java_services order by name, con_id, inst_id;

no rows selected

SQL> col service_name format a20
col username format a20
col program format a20
set num 8
select sess.service_name, sess.username,sess.program, count(*)
from
v$session sess,
dba_users usr,
x$kgllk lk,
x$kglob
where kgllkuse=saddr
and kgllkhdl=kglhdadr
and kglobtyp in (29,56)
and sess.user# = usr.user_id
and usr.oracle_maintained = 'N'
group by sess.service_name, sess.username, sess.program
order by sess.service_name, sess.username, sess.program;

no rows selected

APEX

检查当前数据库是否使用 APEX：

SQL> select workspace, workspace_id from apex_workspaces;
select workspace, view_date, seconds_ago from apex_workspace_activity_log
