Interval = 3, Count=5 Logon= @ ORACLE 10.2.0.2.0 Streams Pool Size = 152M LOG : NET: Cxxx: MEM : % PRxx: Qx : PSxx: Axxx: : flow control in effect : potential bottleneck AR: apply reader AS(n): n number of apply server : xx->: database instance name 2. metalink还提供了一个stream环境的check脚本, Health Check Script 详情请参看ID 273674.1 脚本可以在metalink下载,这个脚本可以生成一个html的报表,报表包含了stream环境的性能数据。 ################################################################ 第三部分 stream环境归档日志的管理 对于stream复制环境的源数据库一端,对归档日志的清理需要注意一些问题,不是所有的归档都可以随意删除,如果误删了capture进程还需要读取的归档日志就会出现capture虽然能正常启动 status也是enable状态, 但是数据缺无法复制。这里需要注意一个capture进程的参数REQUIRED_CHECKPOINT_SCN这个参数表示capture进程重新启动时需要scan的最小scn号,可以通过这个参数找到需要为capture进程保留的归档日志。这里还需 要讲的一个参数是capture进程的_CHEKPOINT_FREQUENCY参数这个参数的表示logminer做一次checkpoint需要挖掘的日志大小,这个参数的单位是M,ORACLE官方建议设置为500M,也就是说当logminer处理了500M大小的 redo的时候会做一次logminer的checkpoint,checkpoint之后REQUIRED_CHECKPOINT_SCN被更新,所以通过设_CHEKPOINT_FREQUENCY的大小,可以控制需要保留的归档的大小,可以使用dbms_capture_adm.set_parameter过程 修改_CHEKPOINT_FREQUENCY参数 下边的查询可以查出capture如果重启所需要读取的redo COLUMN CONSUMER_NAME HEADING 'Capture|Process|Name' FORMAT A15 COLUMN SOURCE_DATABASE HEADING 'Source|Database' FORMAT A10 COLUMN SEQUENCE# HEADING 'Sequence|Number' FORMAT 99999 COLUMN NAME HEADING 'Required|Archived Redo Log|File Name' FORMAT A40 SELECT r.CONSUMER_NAME, r.SOURCE_DATABASE, r.SEQUENCE#, r.NAME FROM DBA_REGISTERED_ARCHIVED_LOG r, DBA_CAPTURE c WHERE r.CONSUMER_NAME = c.CAPTURE_NAME AND r.NEXT_SCN >= c.REQUIRED_CHECKPOINT_SCN;
