實驗-修改trail文件的大小
先看原文檔:
Changing the size of trail files
更改trail 文件的大小
You can change the size of trail files with the MEGABYTES option of either the ALTER EXTTRAIL
or ALTER RMTTRAIL command, depending on whether the trail is local or remote. To change
the file size, follow this procedure.
你可以通過alter 命令調整MEGABYTES 參數的值來改變trail 文件的大小,是使用ALTER EXTTRAIL
或者 ALTER RMTTRAIL要看trail 文件是在本地還是在其它地方
1. Issue one of the following commands, depending on the location of the trail,to view the
path name of the trail you want to alter and the name of the associated Extract group.
Use a wildcard to view all trails.
使用下面的命令獲得你想修改trail 文件的存放地址,你的trail文件所屬的組
(Remote trail)
INFO RMTTRAIL *
(Local trail)
INFO EXTTRAIL *
2. Issue one of the following commands, depending on the locationof the trail, to change
the file size.
(Remote trail)
ALTER RMTTRAIL <trail name>, EXTRACT <group name>, MEGABYTES <n>
(Local trail)
ALTER EXTTRAIL <trail name>, EXTRACT <group name>, MEGABYTES <n>
3. Issue the following command tocause Extract to switch to the next file in the trail.
SEND EXTRACT <group name>, ROLLOVER
