手 头 也 有 一 个 ORACLE DB, 也 是 用 FLASHCOPY的 方 法 , STORAGE也 是 IBM的 。
这 个 的 PROCEDURE如 下 :
1) From backup server, remote issue command to the db server to put Oracle DB in backup mode
2) Issue command to the storage server to take the flashcopy of all the storage(File systems) for Oracle data files
3) Issue command to the db server to pull db out of backup mode
4) Issue command to the db server to archive all the redo logs
5) Issue command to the storage server to take take flashcopy of the storage (file system) for Oracle archived logs
Up to this point, the db backup completes. Then from the backup server, send the flashcopied-image to the tape library
跟 DB2不 同 的 是 , 因 为 ORACLE在 BACKUP MODE时 还 可 以 接 受 TRANSACTION, 这 整 个 过 程 不 会 有 TRANSACTION ERROR。 |
