Solve connect to Idle instance problem
First step
View Oracle_sid.
[Oracle@linuxserver ~]$ Echo $ORACLE _sid
Cjdl
The SID here is the same as initializing the file Spfilecjdl.ora.
[Oracle@linuxserver ~]$ CD $ORACLE _home
[Oracle@linuxserver 11.2.0]$ CD DBS
[Oracle@linuxserver dbs]$ ls
Hc_cjdl.dat hc_dbua0.dat Init.ora lkcjdl orapwcjdl Spfilecjdl.ora
In most cases, it's because there's a problem.
Second Step
[Oracle@linuxserver dbs]$ Export ORACL
