I am a retired developer, not a DBA, with a home computer (Windows Vista Home Basic) that has had an Oracle 11g Enterprise Edition database running on it without problems. I accidentally ran a script that I should not have run and now I cannot login. I am hoping that someone can help me fix it. I have poked around somewhat, but am hoping that someone will just provide a quick spoonfeed, so I can get it up and running again.

This is the script that I ran, with settings that do not correspond to my system and apparently with obsolete parameters:

set echo on
connect sys/orcl as sysdba 
alter system set log_archive_start=true scope=spfile;
alter system set log_archive_dest='/tmp/' scope=spfile;
shutdown immediate;
startup pfile=init.ora mount
alter database archivelog;
alter database open;


I have tried shutting down my laptop computer and re-starting it. The Oracle services all show started and automatic, but when I try to login through SQL*Plus I get:

SQL*Plus: Release 11.1.0.6.0 - Production on Mon Apr 7 21:55:22 2008

I don't know what the correct pfile or spfile was or how to find it or how to fix the archive log mess. Please help me.

log_archive_start has been deprecated. please don't use it.
setting log_archive_dest='/tmp/' is ok but I think you don't have /tmp location in your computer. As you are in windows edition . So locate like 'C:\'.

By the way you can run your database now with another newly created pfile only by putting the entry of right control_files parameter in it.

The problem has been solved, thanks to some quick PM's from anacedent. Here is what fixed it, in case anyone else ends up in a similar situation.

By doing:

create pfile from spfile;

it created a new pfile with today's date.

So, by doing:

dir init*.ora/s/p

I was able to locate the new pfile, edit it, remove the two lines that said:

*.log_archive_dest='/tmp/'
*.log_archive_start=TRUE

then startup using the new pfile with the directory path.

Thanks a millions to anacedent!

Assuming you previously were in noarchivelog mode, you can use:
startup mount;
alter system reset log_archive_start scope=spfile sid='*';
alter system reset log_archive_dest scope=spfile sid='*';
alter database noarchivelog;
shutdown
startup

If this does not work, you can:
startup nomount;
create pfile from spfile;
-- here, remove the 2 lines from pfile in notepad
create spfile from pfile;
alter database mount;
alter database noarchivelog;
shutdown
startup

Michel

Arju,
If you want to promote your site do it in Marketplace forum.

It is annoying to see you repeating the same things that are in the topics to promote your new pages.
You do it, good, don't promote it in the topics.

Regards
Michel
