RMAN-03002 RMAN-06091，9i

寫了一個備份腳本：其中備份完之後，刪除過期備份，保證空間可用。

 

點擊(此處)摺疊或打開

run{
 allocate channel d1 device type disk;
 allocate channel d2 device type disk;
 backup as compressed
backupset DATABASE include CURRENT controlfile;
 delete noprompt
obsolete redundancy 1;
 release channel
d1;
 release channel
d2;
}

原本 在 oracle 10g下運行良好。
可是在9i  中運行報錯
    
 RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of delete command at 12/30/2013 13:51:36
RMAN-06091: no channel allocated for maintenance (of an appropriate type)

沒有可用的維護通道，於是加入 ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE disk;
總是提示：
RMAN-00558: error encountered while parsing input commands
RMAN-01005: syntax error: found "for": expecting one of: "channel_id, double-quoted-string, identifier, single-quoted-string"
RMAN-01007: at line 5 column 18 file: standard input

查詢官方文檔明確指出： ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE disk; 是不包含在RUN塊中的

• Execute this command only at the RMAN prompt. This command cannot be used within a RUN block.

但是又不想寫2個腳本。多次嘗試，
ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE disk; 這個放在RUN塊之外，最底層，問題解決了

正確的腳本：

點擊(此處)摺疊或打開

ALLOCATE CHANNEL FOR MAINTENANCE
DEVICE TYPE disk;
run{
 allocate channel d1 device type disk;
 allocate channel d2 device type disk;
 backup as compressed
backupset DATABASE include CURRENT controlfile;
 delete noprompt
obsolete redundancy 1;
 release channel
d1;
 release channel
d2;
}
