Today linux login sqlplus in a test environment, you can not log in normally report: ORA-01033 errors, fiddle for a long time, refer to some online experience, and finally resolved, sum up the experience.
I. First of all: the cause of the problem, this error is because the file under the opt on the public test environment we use / oracle / oradata directory is deleted by mistake, then try to do some file recovery, or does not work.
Second, the phenomenon: SQL * Plus can not connect, the following error: ORA-01033: ORACLE initialization or shutdown in progress
III analysis: Oracle should be after the start, when the user logs you want to program is loaded into the original configuration information, loading encountered in the original file is not found on the specified location, so they reported the error.
Fourth, the resolution process:
a DBA user logs on, the specific command is
sqlplus / NOLOG
> Connect sysdba / sysdba AS sysdba
Tip: Successfully
> shutdown normal
(Such a long time not stopped)
So execution
>shutdown immediate
Tip: The database has been shut down already uninstalled ORACLE database instance shut down
> startup mount
