The Oracle instance can't start up.
After you login using SQLPlus you see this message:
c:\> sqlplus /nologSQL> conn sys as sysdba
SQL> Connected to an idle instance.
if you type the command "startup" you get this message:
ORA-00401: the value for parameter compatible is not supported by this release
If the customer has run this command:
SQL> ALTER SYSTEM SET COMPATIBLE = '10.2.0.4.0' SCOPE=SPFILE;
before to upgrade the Database from 10.2.0.3 to 10.2.0.4; he has to reverte back the changes to be able to run the upgrade again, following carefully the documentation.
Here the steps to reverte back the changes:
- create a new file newpfile.ora on the Oracle server and add the following line:
- open a Command prompt from the same folder of the file newpfile.ora and login in SQLPLUS using "sys as sysdba" and run this command:
SQL > startup pfile=newpfile.ora
- the Oracle instance will start
- run this command to reverte back the changes:
SQL> ALTER SYSTEM SET COMPATIBLE = '10.2.0.3.0' SCOPE=SPFILE;
