ORA-011033: ORACLE initialization or shutdown in progress

It may be the case, the database did not stop correctly.

Try out following.

Open Dos command Prompt

c:> sqlplus /nolog

sql> connect sys/manager as sysdba

sql>shutdown immediate

sql> startup

sql> exit

While startup it may show error message like some of the parameter is missing. Note down that parameter and update in initSID.ora file.

or 

fter some googling I found the advice to do the following:

> sqlplus /nolog

> SQL> connect / as sysdba

Connected.

> SQL> shutdown abort

ORACLE Instance shut down.

> SQL> startup nomount

ORACLE Instance started

> SQL> alter database mount;

> SQL> alter database open;

Which still gave the error:

ORA-00600: internal error code, arguments: [kcratr1_lostwrt]

I then found the advice to do the following:

> SQL> startup mount

ORACLE Instance started

> SQL> recover database

Media recovery complete

> SQL> alter database open

Database altered
