2、查看tablespace信息
SYS@ TestDB12>select file_id,file_name,tablespace_name,bytes/1024/1024 from dba_data_files; FILE_ID FILE_NAME TABLESPACE_NAME BYTES/1024/1024 ---------- -------------------------------------------------- ------------------------------ --------------- 4 /u01/app/oracle/oradata/TestDB12/users01.dbf USERS 5 3 /u01/app/oracle/oradata/TestDB12/undotbs01.dbf UNDOTBS1 115 2 /u01/app/oracle/oradata/TestDB12/sysaux01.dbf SYSAUX 570 1 /u01/app/oracle/oradata/TestDB12/system01.dbf SYSTEM 730 5 /u01/app/oracle/oradata/TestDB12/example01.dbf EXAMPLE 345.625 6 /u01/app/oracle/oradata/TestDB12/logmnrtbs01.dbf LOGMNRTBS 100 6 rows selected.
--作为logminer的应用表空间，“LOGMNRTBS"初始只分配了100M的size，估计在做sql apply时，空间不足，而不能分配extent。
三、解决方法
1、扩展“LOGMNRTBS" size
SYS@ TestDB12>alter database datafile 6 resize 500m; Database altered. SYS@ TestDB12>select file_id,file_name,tablespace_name,bytes/1024/1024 from dba_data_files; FILE_ID FILE_NAME TABLESPACE_NAME BYTES/1024/1024 ---------- -------------------------------------------------- ------------------------------ --------------- 4 /u01/app/oracle/oradata/TestDB12/users01.dbf USERS 5 3 /u01/app/oracle/oradata/TestDB12/undotbs01.dbf UNDOTBS1 115 2 /u01/app/oracle/oradata/TestDB12/sysaux01.dbf SYSAUX 570 1 /u01/app/oracle/oradata/TestDB12/system01.dbf SYSTEM 730 5 /u01/app/oracle/oradata/TestDB12/example01.dbf EXAMPLE 345.625 6 /u01/app/oracle/oradata/TestDB12/logmnrtbs01.dbf LOGMNRTBS 500 6 rows selected.
四、在备库上做SQL APPLY
SYS@ TestDB12>alter database start logical standby apply immediate;
Database altered.
1、查看logmnr视图：
SYS@ TestDB12>select *from v$logstdby_stats; NAME VALUE ---------------------------------------------------------------- ---------------------------------------------------------------- logminer session id 1 number of preparers 1 number of appliers 5 server processes in use 9 maximum SGA for LCR cache (MB) 30 maximum events recorded 10000 preserve commit order TRUE transaction consistency FULL record skipped errors Y record skipped DDLs Y record applied DDLs N record unsupported operations N realtime apply Y apply delay (minutes) 0 peak apply rate (bytes/sec) 15148888 coordinator state IDLE coordinator startup time 12-MAR-15 coordinator uptime (seconds) 96 txns received from logminer 1523 txns assigned to apply 1523 txns applied 1523 txns discarded during restart 0 large txns waiting to be assigned 0 session restart SCN 1332344 rolled back txns mined 501 DDL txns mined 11 CTAS txns mined 0 bytes of redo mined 72757172 bytes paged out 0 pageout time (seconds) 0 bytes checkpointed 133310 checkpoint time (seconds) 0 system idle time (seconds) 0 standby redo logs mined 0 archived logs mined 15 gap fetched logs mined 7 standby redo log reuse detected 0 logfile open failures 0 current logfile wait (seconds) 0 total logfile wait (seconds) 0 thread enable mined 0 thread disable mined 0 distinct txns in queue 0 43 rows selected.

五、查看数据库同步信息
主库：
sys@TESTDB12>select count(*) from scott.emp1;
COUNT(*)
----------
120
备库：
SYS@ TestDB12>select count(*) from scott.emp1;
COUNT(*)
----------
120
此时主库和备库数据已经同步！
