Basic Oracle Concepts and Programming Question:

The sample initialization parameter file provided by Oracle seems to be not working. But we can try to start the new instance with a minimal initialization parameter file (PFile). First you can create another PFile, $ORACLE_HOME/database/initggl_ini_min.ora, as shown below:

db_name=ggl
control_files=("oraclexeoradatagglcontrol.dbf")
undo_management=AUTO

Then start the ggl instance again:

SQL> CONNECT / AS SYSDBA
Connected.

SQL> STARTUP NOMOUNT
PFILE=$ORACLE_HOME/database/initggl_ini_min.ora

ORACLE instance started.
