OGG的PURGEOLDEXTRACTS不能工作问题的解决

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
