hello,and thanks for response
yesterday I recreated a database in archivelog mode.previously it was in noarchivelog mode.
today morning i saw some errors in alertlog like this-
ARC0: Beginning to archive log# 1 seq# 1021
Mon Nov 06 11:47:19 2000
Thread 1 cannot allocate new log, sequence 1023
All online logs needed archiving
Current log# 2 seq# 1022 mem# 0: E:\ORACLE\ORADATA\ORTEL\REDO02.LOG
Mon Nov 06 11:47:21 2000
ARC0: Completed archiving log# 1 seq# 1021
ARC0: re-scanning for new log files
ARC0: prodding the archiver
ARC0: STARTING ARCH PROCESSES
ARC1: Failed to archive log# 2 seq# 1022

so on seeing this i changed the parameters in init.ora
as i am not being able to connect as internal -
so i cant do alter database noarchivelog;
restarted the db.

within 5 minutes i got this errors
oracle error during redolog archival ,cannot allocate log
archival needed.
as previuosly stated-
can u get it?hurry pl.

so basically you are still in archivelog, why you cant connect with internal? Do you use passwordfile, if you do you can connect with sys or system with sysdba or sysoper role to startup or shutdown the database.
Is it in UNIX or NT, production or development

also try

alter system archive log start to '/another_directory';
to change the directory of archive logs

or
alter system archive log stop;
this will stop archive process ARCH0 & ARCH1

[siroracle]

U must do

ALTER DATABASE ARCHIVELOG

U cannot just alter the init.ora.

[pando]

I think he cant even do that since he cant connect as internal to startup the database in mount state to change to noarchive log, I guess it´s fasterby stopping the ARCH processes to stop archiving

[siroracle]

but if he wants archiving...he nust do the alter system archivelog thing

I didn't understand why he can't connect as internal?!?!?

[pando]

I think he is in archivelog already, well according to his alert log it seems like the ARCH0 & 1 are trying to archive the logs anyway.

I dont know why he cant connect as internal neither :o May be he is running 9i? :D just kidding

[siroracle]

what's with the 9i? there is not internal there? :)

[pando]

yea I heard internal is gone in 9i, it was supposed to be phase out in 8.1.7 though :)
