Oracle启动错误

Oracle启动错误

    key words: "  shared memory realm does not exist"  Oracle10g启动错误

上次安装的Oracle10g启动出现了问题，提示:

ORACLE not available
ORA- 27101 : shared memory realm does not exist
Linux Error:  2 : No such file or directory

google了一下，有人有如下提议:
make sure that both ORACLE_HOME and ORACLE_SID are written correctly.
In past, I've got same error because ORACLE_HOME in init script was
/opt/oracle/9iR1/ but the real ORACLE_HOME was /opt/oracle/9iR1 without ending slash.
Yes, a simple slash implies two different installation.
If in your scritps/programs you use sometime /opt/oracle/9iR1 and sometime /opt/oracle/9iR1/
(with ending slash) you'll fall in troubble!.
When u got "shared memory realm does not exist " at first check du a "ps -fe | grep ora"
in order to make sure if the instance is running.
also, if you want see that "shared memory realm" you can type "ipcs". If oracle is alive you can see a
huge segment of memory (aslo know as SGA)


最后检查结果好像也不是这个，是配置文件出错,即服务名不一致:

其中SERVICE_NAME与SID_NAME一定要和.bash_profile中的ORACLE_SID相一致，否则无法启动
