1 00446

OGG 的一些錯誤編號，包含了不少種不一樣的緣由。00446 就是這樣的一種，不一樣的緣由有不一樣的提示。本文包含兩種：

Missing filename opening checkpoint file
could not find archived log

下面看分析與解決方法。css

1.1 Missing filename opening checkpoint file

1.1.1 錯誤信息

2019-07-02T23:26:17.998+0800  ERROR   OGG-00446  Oracle GoldenGate Delivery, xmsys.prm:  Missing filename opening checkpoint file.
2019-07-02T23:26:17.999+0800  ERROR   OGG-01668  Oracle GoldenGate Delivery, xmsys.prm:  PROCESS ABENDING.

1.1.2 分析

出現此錯誤，緣由是參數配置與命令不匹配。好比from file方式的數據應用進程,若是使用ggsci命令start命令來啓動, 則會出現這種錯誤。下面是兩則安全，根本緣由都是命令與參數配置不匹配，一種是初始化，一種是實時應用。html

案例1->初始化

參數配置 如下配置爲一例 ogg for kafka 的 From File 方式初始化應用進程的配置。 java

  SPECIALRUN    -- 此行爲重點
END RUNTIME
SETENV(nls_lang="AMERICAN_AMERICA.ZHS16GBK")
targetdb libfile libggjava.so set property=dirprm/xmins.props
EXTFILE dirdat/ii
reportcount every 1 minutes , rate
grouptransops 10000

啓動命令python
```
start initsp
```

解決經過操做系統命令 replicat 執行初始化:shell
```
$OGG_HOME/replicat paramfile $OGG_HOME/dirprm/xmsys.prm
```

案例2->實時抽取

參數配置 api

  passthru
rmthost 192.168.153.129, mgrport 7809
rmttrail /u02/ggs/dirdat/td
gettruncates
table scott.*;
sequence scott.*;

分析第一行應爲:sass
```
extract test
```

1.2 could not find archived log

1.2.1 錯誤信息

在ggserr.log 中發現以下錯誤:安全

1.2.2 分析

從錯誤信息提示來看，是歸檔日誌找不到引發的中斷。經查看歸檔日誌確實不存在。已被物理刪除。且沒有備份。ruby

數據不重要

此時能夠修改extract 的起始值,跳過缺失的歸檔文件，這在測試和開發環境中應用較多。首先查看可用歸檔:

select sequence# ,first_change#, next_change# ,deleted,applied,status from v$archived_log;

 sequence# first_change# next_change# del applied   s
---------- ------------- ------------ --- --------- -
      3759      16360310     16401138 yes no        a
      3760      16401138     16419033 no  no        a

從上面的查詢結果來看，3759號歸檔已被刪除，最新可用歸檔是3760. 對應最先的 scn號是16401138. 將extract 進程的scn 值調整至16401138:

alter extrace extxmdev, scn 16401138
start ext extxmdev

數據重要

此時須要從備份中恢復相應的歸檔文件
