在配置OGG的清理老的trail文件的时候,设置了两行配置: PURGEOLDEXTRACTS /ogg/dirdat/horcl/hz*,USECHECKPOINTS,MINKEEPDAYS 2 PURGEOLDEXTRACTS /ogg/dirdat/aorcl/ar*,USECHECKPOINTS,MINKEEPDAYS 2 但是发现第二行不起作用
在配置OGG的清理老的trail文件的时候,设置了两行配置:
PURGEOLDEXTRACTS /ogg/dirdat/horcl/hz*,USECHECKPOINTS,MINKEEPDAYS 2
PURGEOLDEXTRACTS /ogg/dirdat/aorcl/ar*,USECHECKPOINTS,MINKEEPDAYS 2
但是发现第二行不起作用
检查参数文件,发现extract参数文件中配置的参数文件的exttrail配置如下:
EXTTRAIL ./dirdat/aorcl/ar
同时发现e_aorcl这个extract对应了两个exttrail
GGSCI (ncrac1) 8> info exttrail *
Extract Trail: /ogg/dirdat/aorcl/ar
Seqno Length: 6
Flip Seqno Length: yes
Extract: E_AORCL
Seqno: 0
RBA: 0
File Size: 500M
Extract Trail: ./dirdat/aorcl/ar
Seqno Length: 9
Flip Seqno Length: no
Extract: E_AORCL
Seqno: 20
RBA: 136368447
File Size: 500M
停掉extract删除了对于的exttrail
GGSCI (ncrac1) 13> delete exttrail /ogg/dirdat/aorcl/ar extract e_aorcl
Deleting extract trail /ogg/dirdat/aorcl/ar for extract E_AORCL
同时,在mgr中加入了一行, 文件路径与extract参数中对应:
PURGEOLDEXTRACTS ./dirdat/aorcl/ar*,USECHECKPOINTS,MINKEEPDAYS 2
之后refresh mgr之后,工作正常
