host_a 正在運行的數(shù)據(jù)庫

host_b 用于恢復(fù)

操作步驟：

◆1.新建host_b機，安裝操作系統(tǒng)，安裝數(shù)據(jù)軟件，只需要配置一下實例名就可以了，不需要初始化，把數(shù)據(jù)文件建立的和host_a機一樣。

配置cfg文件的時候，把實例名做相應(yīng)的更改即可。

◆2.host_b機安裝rsh服務(wù)器軟件，啟動rsh服務(wù)。

◆3.配置host_b機信任host_a機。

◆4.在host_a上執(zhí)行：

ontape -s -L 0 -F | rsh host_b "ontape -p"

實際執(zhí)行的時候運行：

ontape -s -L 0 -F | rsh tonykorn9710 "ontape -p"

Please mount tape 1 on /dev/null and PRess Return to continue ...

Program over.

Physical restore failed - function read archive backup failed code 1 errno 0

或者：

ontape -s -L 0 | rsh tonykorn9710 "ontape -p"

Your evaluation license will expire on 2008-01-15 00:00:00

Please mount tape 1 on /dev/null and press Return to continue ...

Program over.

Physical restore failed - function read archive backup failed code 1 errno 0

informix@tonykorn97:~/etc>

◆5.需要把指使ontape 備份到標準輸出：

ontape -s -L 0 -t STDIO | rsh tonykorn9710 "ontape -p -t STDIO"

用上面語句備份報錯:

informix@tonykorn97:~/etc> ontape -s -L 0 -t STDIO -F| rsh tonykorn9710 "ontape -p -t STDIO"

Your evaluation license will expire on 2008-01-15 00:00:00

Backup data version is not compatible with Online version:

IBM Informix Dynamic Server Version 10.00.UC4

Physical restore failed - function Invalid archive tape failed code -1 errno 0

日志顯示:

10:06:52 Maximum server connections 1

10:06:52 Level 0 Archive started on rootdbs, plogdbs, llogdbs, datadbs

10:06:53 Archive on rootdbs, plogdbs, llogdbs, datadbs ABORTED.

10:06:53 Aborted by client.

◆6.修改兩臺服務(wù)器的cfg文件，把TAPEDEV和LTAPEDEV都修改為：STDIO

重啟host_a數(shù)據(jù)庫。執(zhí)行：

ontape -s -L 0 | rsh tonykorn9710 "ontape -p"

效果還是一樣的。

◆7.經(jīng)提示是rlogin服務(wù)沒有起，啟動rlogin服務(wù)。執(zhí)行

informix@tonykorn97:~> ontape -s -L 0 | rsh tonykorn9710 "ontape -p"

Your evaluation license will expire on 2008-01-15 00:00:00

Backup data version is not compatible with Online version:

IBM Informix Dynamic Server Version 10.00.UC4

Physical restore failed - function Invalid archive tape failed code -1 errno 0

◆8.此時發(fā)現(xiàn)版本不一致，重新調(diào)整版本！

第一次執(zhí)行：

informix@tonykorn97:~> ontape -s -L 0 | rsh tonykorn9710 "ontape -p"

Physical restore failed - Bad READ/WRITE permissions: '/informix.links/rootdbs'.

◆9.權(quán)限不對，重新執(zhí)行：

ontape -s -L 0 | rsh tonykorn9710 "ontape -p"

成功!

◆10.host_b數(shù)據(jù)庫一直在CKPT.沒有辦法殺掉進程。

[informix@Oracle10 ~]$ onstat -m

IBM Informix Dynamic Server Version 10.00.UC4 -- Fast Recovery (CKPT REQ) -- Up 07:21:33 -- 28024 Kbytes

Blocked:CKPT

◆11.重新執(zhí)行

ontape -s -L 0 -F | rsh oracle10 "ontape -p"

7個小時后host_b機還是一直CKPT

IBM Informix Dynamic Server Version 10.00.UC4 -- Fast Recovery (CKPT REQ) -- Up 07:16:36 -- 28024 Kbytes

Blocked:CKPT

◆12.在host_b服務(wù)器上把數(shù)據(jù)庫重啟即可。
