Oracle查看控制文件的配置

作者：雨竹清风 要想得到控制文件的全部信息可以使用v$controlfile_record_section数据字典。命令如下：SQL> desc v$controlfile_record_section 名称 是否为空? 类型 ----------------------------------------- -------- ---------------------------- TYPE VARCHAR2(28) RECORD_SIZE NUMBER RECORDS_TOTAL NUMBER RECORDS_USED NUMBER FIRST_INDEX NUMBER LAST_INDEX NUMBER LAST_RECID NUMBER SQL> select TYPE, RECORD_SIZE, RECORDS_TOTAL,RECORDS_USED from v$controlfile_record_section; TYPE RECORD_SIZE RECORDS_TOTAL RECORDS_USED ---------------------------- ----------- ------------- ------------ DATABASE 316 1 1 CKPT PROGRESS 8180 11 0 REDO THREAD 256 8 1 REDO LOG 72 16 3 DATAFILE 428 100 5 FILENAME 524 2298 9 TABLESPACE 68 100 6 TEMPORARY FILENAME 56 100 1 RMAN CONFIGURATION 1108 50 0 LOG HISTORY 56 292 9 OFFLINE RANGE 200 163 0 TYPE RECORD_SIZE RECORDS_TOTAL RECORDS_USED ---------------------------- ----------- ------------- ------------ ARCHIVED LOG 584 28 0 BACKUP SET 40 409 0 BACKUP PIECE 736 200 0 BACKUP DATAFILE 116 282 0 BACKUP REDOLOG 76 215 0 DATAFILE COPY 660 223 1 BACKUP CORRUPTION 44 371 0 COPY CORRUPTION 40 409 0 DELETED OBJECT 20 818 1 PROXY COPY 852 249 0 BACKUP SPFILE 36 454 0 TYPE RECORD_SIZE RECORDS_TOTAL RECORDS_USED ---------------------------- ----------- ------------- ------------ DATABASE INCARNATION 56 292 2 FLASHBACK LOG 84 2048 0 RECOVERY DESTINATION 180 1 1 INSTANCE SPACE RESERVATION 28 1055 1 REMOVABLE RECOVERY FILES 32 1000 0 RMAN STATUS 116 141 0 THREAD INSTANCE NAME MAPPING 80 8 8 MTTR 100 8 1 DATAFILE HISTORY 568 57 0 STANDBY DATABASE MATRIX 400 10 10 GUARANTEED RESTORE POINT 212 2048 0 TYPE RECORD_SIZE RECORDS_TOTAL RECORDS_USED ---------------------------- ----------- ------------- ------------ RESTORE POINT 212 2083 0 已选择34行。 也可以通过where语句进行条件限制。如下所示：SQL> select TYPE, RECORD_SIZE, RECORDS_TOTAL,RECORDS_USED from v$controlfile_record_section where type in('TABLESPACE','DATAFILE','REDO LOG'); TYPE RECORD_SIZE RECORDS_TOTAL RECORDS_USED ---------------------------- ----------- ------------- ------------ REDO LOG 72 16 3 DATAFILE 428 100 5 TABLESPACE 68 100 6 初始化参数文件的路径可以通过两种方式得到：方式一：使用v$parameter数据字典。SQL> desc v$parameter 名称 是否为空? 类型 ----------------------------------------- -------- ---------------------------- NUM NUMBER NAME VARCHAR2(80) TYPE NUMBER VALUE VARCHAR2(512) DISPLAY_VALUE VARCHAR2(512) ISDEFAULT VARCHAR2(9) ISSES_MODIFIABLE VARCHAR2(5) ISSYS_MODIFIABLE VARCHAR2(9) ISINSTANCE_MODIFIABLE VARCHAR2(5) ISMODIFIED VARCHAR2(10) ISADJUSTED VARCHAR2(5) ISDEPRECATED VARCHAR2(5) DESCRIPTION VARCHAR2(255) UPDATE_COMMENT VARCHAR2(255) HASH NUMBER SQL> select value from v$parameter where name='control_files'; VALUE --------------------------------------------------------------------------------D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL01.CTL, D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL02.CTL, D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL03.CTL 方式二：使用v$controlfile数据字典。 SQL> desc v$controlfile 名称 是否为空? 类型 ----------------------------------------- -------- ---------------------------- STATUS VARCHAR2(7) NAME VARCHAR2(513) IS_RECOVERY_DEST_FILE VARCHAR2(3) BLOCK_SIZE NUMBER FILE_SIZE_BLKS NUMBERSQL> select NAME from v$controlfile; NAME --------------------------------------------------------------------------------D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL01.CTL D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL02.CTL D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CONTROL03.CTL
