发表于 2017 年 6 月 11 日 由 惜分飞

在redhat 7.3版本中安装oracle rac 12.2的过程中,执行root.sh脚本的第14步的时候报如下错误,导致无法继续

查询mos发下:ACFS Drivers Install reports CLSRSC-400: A system reboot is required to continue installing (Doc ID 2025056.1),主要是由于12c gi开始，acfs默认是安装的，由于acfs在redhat 7.3中不支持导致上述的错误信息.

处理方法
停掉crs,kill 进程(如果有不能停掉的，通过kill处理),执行root.sh

对于11g的版本可以通过_optimizer_null_aware_antijoin参数开启NULL-aware Anti join特性来提高not in的效率,对于11g以下版本可以通过not exists来提高效率

file$ 删除记录恢复(delete file$ recovery)

发表于 2017 年 6 月 3 日 由 惜分飞

最近遭遇几次有人因为对oracle不太理解，由于各种情况下，删除了file$中的部分记录，从而使得该文件之后的文件都丢失，使得数据库出现各种异常情况。这里演示了可以重启数据库的情况下两种常见的删除file$中记录的恢复

创建表空间和表

这里报错明显，由于file$.file#=5被删除，重建控制文件之后，file#在5之后的数据文件全部从控制文件中删除，类似提示File #5 in the controlfile not found in data dictionary. Removing file from controlfile.

WARNING: The following temporary tablespaces contain no files.
         This condition can occur when a backup controlfile has
         been restored.  It may be necessary to add files to these
         tablespaces.  That can be done using the SQL statement:
 
         ALTER TABLESPACE <tablespace_name> ADD TEMPFILE
 
         Alternatively, if these temporary tablespaces are no longer
         needed, then they can be dropped.

WARNING: Files may exists in db_recovery_file_dest
that are not known to the database. Use the RMAN command
CATALOG RECOVERY AREA to re-catalog any such files.
If files cannot be cataloged, then manually delete them

One of the following events caused this:
1. A backup controlfile was restored.
2. A standby controlfile was restored.
3. The controlfile was re-created.
4. db_recovery_file_dest had previously been enabled and
   then disabled.

通过插入删除记录,重建控制文件,数据库恢复正常,而且相关记录也可以查询。

结论总结
1. 如果删除file$中的记录,而且控制文件未重建,数据库可以正常启动,而且可以查询数据
2. 如果删除file$中的记录,而且控制文件被重建,在数据库启动过程中,从被删除文件之后的所有文件记录从控制文件中删除(类似:File N in the controlfile not found in data dictionary. Removing file from controlfile.).可以在数据库open之后,插入被删除的记录,重建控制文件,数据会被恢复回来.如果数据库无法启动,需要通过其他方式进行恢复被删除记录
