用BBED修复坏块

笔记本上安装的 oracle 9208数据库在演示RMAN备份时发现system01.dbf有一坏块,用dbv检查如下:
C:\Documents and Settings\bwen>dbv file=D:\ oracle \oradata\bright\system01.dbf blocksize=8192

项目介绍:一客户MES系统升级

一客户MES系统目前运行情况如下:

从上图可以看出CPU已经无法满足需求,因此客户决定对系统进行升级改造。

CRS无法启动的解决过程

一客户报RAC一节点的CRS无法启动,通过VPN远端连过去检查crs,如下:
# crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM 
检查crs进程:
# ps -ef | grep css

Oracle CRS log

oracle RAC出问题时我们往往需要查看其log和trace文件,那么这些log及trace存在哪里呢?下图就是一个log目录结构示意图,较直观的显示了log存放的地方:

ORA-12545:Connect failed because target host or object does not exist

客户环境:Linux+ oracle 10.2.0.2+RAC
现象:客户端用sqlplus连接统一服务名时报ORA-12545错误。
-------------------------------------------
我们先看ORA-12545错误是什么:
[ oracle @orac1 udump]$ oerr ora 12545
12545, 00000, “Connect failed because target host or object does not exist”
// *Cause: The address specified is not valid, or the program being
// connected to does not exist.
// *Action: Ensure the ADDRESS parameters have been entered correctly; the
// most likely incorrect parameter is the node name. [...]

2007年数据库市场分析报告
