請教：log_archive_dest_1

cheungjustin

log_archive_dest_1
log_archive_dest_2
log_archive_dest_3

雖不是這些路徑如果設(shè)置三個(gè)的話，那么redo log 會同時(shí)往這幾個(gè)路徑裡面歸檔啊？

看一下oracle DB的參數(shù)說明你就知道怎么回事了。下面是截取的一段：
The LOG_ARCHIVE_DEST_n  initialization parameter defines up to ten (where n = 1, 2, 3, ... 10) destinations, each of which must specify either the LOCATION or the SERVICE attribute to specify where to archive the redo data. All other attributes are optional. Note that whether you are specifying the LOCATION  attribute or the SERVICE attribute, it must be the first attribute supplied in the list of attributes.

If you choose not to enter any attributes, you can specify a null string by entering the following:

LOG_ARCHIVE_DEST_n=' ';

You set the attributes for the LOG_ARCHIVE_DEST_n initialization parameter to control different aspects of how redo transport services transfer redo data from a production or primary database destination to another (standby) database destination. You can query the V$ARCHIVE_DEST view to see the current attribute settings for each destination (n).

For every LOG_ARCHIVE_DEST_n initialization parameter that you define, you must specify a corresponding LOG_ARCHIVE_DEST_STATE_n parameter. The LOG_ARCHIVE_DEST_STATE_n (where n is an integer from 1 to 10) initialization parameter specifies whether the corresponding destination is currently enabled or disabled.

樓上這段兒，有沒有中文版本？
