1. 启动时报：SYSTEM ERROR: Wrong dbkey in block. Found 0, should be 6342528 in area 36.
(439) ** Save file named core for analysis by Progress Software Corporation.
原因：查看数据库.lg日志文件，确认是数据库没有还原成功（注：.lg文件盒数据库文件在同一目录
[2015/12/07@00:19:18.579+0800] P-31305 T-14415552 I : (12854) Restoring database from XXXXXXXXXX.db.

2. 重新还原时，报
Start of extending target DB to needed size... (9432)
Unable to extend before-image files enough to proceed. (6743)
Check for fixed length extents. (6744)
Restore failed. (1618)
!!! ERROR - Database restore utility FAILED !!! (8564)
查找之后发现是源数据库的BI文件又两个，而目标数据库的BI文件只有一个
3. 尝试给目标数据库加BI:prostrct add mfgtrain mfgtrain-add.st
You must remove the variable length BI extent before adding
additional BI extent(s). (8225)
prostrct add FAILED. (12867)
确认不好加，所以就想把源数据库的BI删掉，再重新生成一个，也可以释放一点空间。
4. 重新生成BI, 步骤如下：
1) prostrct remove mfgprod bi 执行，提示XXXXXXXXXXX.b2 成功删除
2) prostrct remove mfgpord bi 执行，提示XXXXXXXXXXX.b1 成功删除
3) 创建mfgprod-add.st。 内容：b /qad/qad2010/db/mfgprod.b1
执行 prostrct add mfgprod mfgprod-add.st
5. 备份还原
probkup XXXXXXXXmfgprod XXXXXmfgprod.bak 备份
prorest XXXXXXXXmfgdemo XXXXXmfgprod.bak 还原
