SAP basis随手记

1、RZ03 启动停止单个instance

2、临时调整Memory大小，重启后失效SE38-->RSMEMORY

3、更改oracle数据文件名

在backup中发现

错误File name not unique Backup verification not possible

类似于：BR0069E File name /oracle/DEV/sapdata3/sr3_10/sr3.data10 not unique - backup/ver ification not possible

解决方法：修改datafile name。  note 17163 - BRARCHIVE/BRBACKUP messages and codes

User action:  Stop the database. Rename the file at operating system level. Use the SYRMGR commands to rename the file on the database.

a)连接数据库，shutdown immediate

b)在os层面直接修改datefile name

c)数据库 startup mount

d)数据库命令：alter database rename file '<file name>' to '<file name>';

e)alter database open

f)重新backup
