前言

最近客户反应，DG的逻辑备库无法同步数据，经过排查发现，逻辑备库表空间不足导致 报错如下： ORA-01658: unable to create INITIAL extent for segment in tablespace LOGMNRTBS

2.处理步骤

2.1 主库LOGMNRTBS表空间新增数据文件或改为自动扩展

SYS@PROD> ALTER DATABASE DATAFILE '/u01/app/oracle/oradata/PROD/logmnrtbs1.dbf' AUTOEXTEND ON;

2.2 查询表空间

SELECT SUM(bytes) / (1024 * 1024) AS free_space, tablespace_name 
FROM dba_free_space 
GROUP BY tablespace_name; 
SELECT a.tablespace_name, 
a.bytes total, 
b.bytes used, 
c.bytes free, 
(b.bytes * 100) / a.bytes "% USED ", 
(c.bytes * 100) / a.bytes "% FREE " 
FROM sys.sm$ts_avail a, sys.sm$ts_used b, sys.sm$ts_free c 
WHERE a.tablespace_name = b.tablespace_name 
AND a.tablespace_name = c.tablespace_name; 

2.3 备库LOGMNRTBS表空间新增数据文件或改为自动扩展

SYS@PRODDG> ALTER DATABASE DATAFILE '/u01/app/oracle/oradata/PRODDG/logmnrtbs1.dbf' AUTOEXTEND ON;

SELECT SUM(bytes) / (1024 * 1024) AS free_space, tablespace_name 
FROM dba_free_space 
GROUP BY tablespace_name; 
SELECT a.tablespace_name, 
a.bytes total, 
b.bytes used, 
c.bytes free, 
(b.bytes * 100) / a.bytes "% USED ", 
(c.bytes * 100) / a.bytes "% FREE " 
FROM sys.sm$ts_avail a, sys.sm$ts_used b, sys.sm$ts_free c 
WHERE a.tablespace_name = b.tablespace_name 
AND a.tablespace_name = c.tablespace_name; 

2.4 备库启用SQL应用

SYS@PRODDG> alter database start logical standby apply immediate;

3 确认数据同步

3.1 主库创建表

3.2 备库确认信息
