下面是OnBar活动日志的摘录,展示了顺序恢复与并行恢复之间的不同之处。
The difference between a sequential and a parallel restore is shown by the following excerpts from the OnBar activity log.
根据Informix的说法,onbar具有比ontape更好的功能;它可以执行并行备份和恢复,将对整体性能有益。
Well, according to Informix, onbar has a better functionality than ontape; it can perform parallel backup and restore and that would be beneficial to overall performance.
并行物理恢复('OnBar -r-p')
IDS现在可以对备份和恢复过程中dbspace的排序做出明智的决策,以取得最大的并行度,从而减少备份和恢复所需的时间。
IDS now makes intelligent decisions regarding the ordering of dbspaces during backup and restore processes to achieve maximum parallelism, thus reducing the backup and restore time necessary.
在恢复根dbspace之后,onbar派生出一些附加的OnBar进程,其他的dbspaces将被并行地处理(基于BAR_MAX_BACKUP)。
After restoring the root dbspace, OnBar forks additional OnBar processes and the remaining dbspaces are processed in parallel mode (up to BAR_MAX_BACKUP).
