OGG 手动删除trail文件

1. OGG手动删除trail文件

OGG mgr定期清理trail 文件可参考以下链接
https://www.cndba.cn/leo1990/article/2853

1.1. 查看源端trail文件信息

GGSCI (cndba) 45>  INFO EXTTRAIL *

       Extract Trail: ./dirdat/et
             Extract: EXT1
               Seqno: 0
                 RBA: 0
           File Size: 100M

       Extract Trail: ./dirdat/ex
             Extract: EXT2
               Seqno: 7
                 RBA: 1075
           File Size: 100M

       Extract Trail: ./dirdat/et
             Extract: PUMP1
               Seqno: 0
                 RBA: 0
           File Size: 100M

       Extract Trail: ./dirdat/ex
             Extract: PUMP2
               Seqno: 3
                 RBA: 1279
           File Size: 100M

1.2. 查看目标端trail文件信息

GGSCI (cndba) 46>  INFO RMTTRAIL *

       Extract Trail: ./dirdat/et
             Extract: EXT1
               Seqno: 0
                 RBA: 0
           File Size: 100M

       Extract Trail: ./dirdat/ex
             Extract: EXT2
               Seqno: 7
                 RBA: 1075
           File Size: 100M

       Extract Trail: ./dirdat/et
             Extract: PUMP1
               Seqno: 0
                 RBA: 0
           File Size: 100M

       Extract Trail: ./dirdat/ex
             Extract: PUMP2
               Seqno: 3
                 RBA: 1279
           File Size: 100M

1.3. 删除trail 文件语法

DELETE RMTTRAIL dirdat/et
相对路径或完全路径，包括两个字符前缀。
使用DELETE EXTTRAIL/RMTTRAIL删除与本地或者远程系统上的跟踪关联的检查点记录。 检查点保存在与Oracle GoldenGate目录的dirchk子目录中的组具有相同名称的文件中。
该命令仅从检查点文件中删除对指定路径的引用。 它不会自行删除跟踪文件。 要删除跟踪文件，请使用标准操作系统命令删除文件。
DELETE EXTTRAIL/RMTTRAIL 这两个命令在源端执行即可删除本地和目标端trail文件检查点记录

1.4. 删除本地trail 文件

GGSCI (cndba) 104> DELETE EXTTRAIL ./dirdat/et
Cannot delete extract trail ./dirdat/et, extract EXT1 is running.
Cannot delete extract trail ./dirdat/et, extract PUMP1 is running.
GGSCI (cndba) 105> stop ext1

Sending STOP request to EXTRACT EXT1 ...
Request processed.

GGSCI (cndba) 106> DELETE EXTTRAIL ./dirdat/et
Deleting extract trail ./dirdat/et for extract EXT1
Cannot delete extract trail ./dirdat/et, extract PUMP1 is running.


GGSCI (cndba) 107> stop pump1

Sending STOP request to EXTRACT PUMP1 ...
Request processed.

GGSCI (cndba) 108> DELETE EXTTRAIL ./dirdat/et
Deleting extract trail ./dirdat/et for extract PUMP1

重新添加extract,pump进程trail文件
注意:如果不执行DELETE EXTTRAIL ./dirdat/et文件只是从操作系统级别删除trail文件，重启extract进程，生成的trail文件序列号会从以前删除的最大的trail文件号加1。执行删除trail 文件命令时，再次生成trail文件会重新从0开始。
ADD EXTTRAIL ./dirdat/et, EXTRACT EXT1
ADD RMTTRAIL ./dirdat/et, EXTRACT PUMP1

1.5. 删除目标端trail文件

先执行以下命令DELETE EXTTRAIL ./dirdat/et
在操作系统级别删除trail文件
