今天處理別的問題查看告警日志偶然發(fā)現(xiàn)大量的報錯,無法擴展SYSAUX表空間,于是登錄系統(tǒng),查看系統(tǒng)表空間使用情況,發(fā)現(xiàn)SYSAUX表空間用滿了,所以本文給大家介紹了Oracle 12.2處理sysaux空間占滿問題,需要的朋友可以參考下

基本環(huán)境

數(shù)據(jù)庫：oracle 12.2 RAC

操作系統(tǒng)：unix&solaris 11.3

報錯現(xiàn)像

今天處理別的問題查看告警日志偶然發(fā)現(xiàn)大量的報錯，無法擴展SYSAUX表空間

于是登錄系統(tǒng)，查看系統(tǒng)表空間使用情況，發(fā)現(xiàn)SYSAUX表空間用滿了

查看SYSAUX表空間情況

使用SQL檢查一下占用，

SELECT occupant_name"Item",round(space_usage_kbytes/1024/1024,3)"Space Used (GB)",schema_name "Schema",move_procedure "MoveProcedure"
FROM v$sysaux_occupants
ORDER BY 2 Desc;

返回如下：

再檢查segment_names查看

select * from (
select segment_name,sum(bytes)/1024/1024 total_mb,tablespace_name from dba_segments where tablespace_name in
('SYSTEM','SYSAUX') group by segment_name,tablespace_name order by 2 desc)
where rownum <=20;

返回如下：

釋放表空間AUD$UNIFIED

需要用到Dbms包來處理

BEGIN
DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL(
audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_UNIFIED,
container => DBMS_AUDIT_MGMT.CONTAINER_CURRENT,
use_last_arch_timestamp => FALSE);
END;
/

use_last_arch_timestamp這個地方有兩個選項：

USE_LAST_ARCH_TIMESTAMP: Enter either of the following settings:
- TRUE: Deletes audit records created before the last archive timestamp. To set the archive timestamp, see Step 3: Optionally, Set an Archive Timestamp for Audit Records. The default (and recommended) value is . Oracle recommends that you set to . TRUEUSE_LAST_ARCH_TIMESTAMPTRUE
- FALSE: Deletes all audit records without considering last archive timestamp. Be careful about using this setting, in case you inadvertently delete audit records that should not have been deleted.

處理完再次查看

清理之后會留下清理記錄，可通過SQL查看

select * from UNIFIED_AUDIT_TRAIL where OBJECT_NAME='DBMS_AUDIT_MGMT' and OBJECT_SCHEMA='SYS' AND SQL_TEXT LIKE '%DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL%';
