How to increase the size and the number of log files

Question

OS Win2000 BD version Oracle8.0.5
When i Execute a big Transaction, for example: Insert into a table with 100,000 records,
Oracle tell me that archive log require,
but I write log_archive_start =true in init.ora;
I think Maybe the size of log file too small?
Any other suggestion?
Thanks

Hello Long Guohui,
If your Database is running in Archive Log mode and if the Automatic Archiving is not enable then obviously Oracle
will ask that "Archive Log Required".
But if your Database is running with NoArchive Log mode then Oracle should never ask you that "Archive Log Required".
If your Database is running with Archive Log Mode then Oracle always recommends that the Tablespace where
you are going to Insert the 1,00,000 records, make that Tablespace Mode from Logging to Nologging, so that
Archive will not be generated for those entries because Redo does not Generate for that Tablespace as it is
Running in Nologging mode. If Redo generates for those 1,00,000 entries then it may affect the other DML
executing in you Database. So it is always recommended to do like this. But after the Insertion is done
successfully Oracle recommends immediately takes the Back of that Tablespace where you have just
Inserted 1,00,000 Data.
For making a Tablespace Nologging:
ALTER TABLESPACE <TABLESPACE NAME> NOLOGGING;
For Making a Database from NoArchive to Archive:
1)     SHUTDOWN IMMEDIATE
2)     IN THE init<sid>.ora FILE SET THE FOLLOWING PARAMETER WITH VALUE:
LOG_ARCHIVE_START = TRUE
3)     STARTUP MOUNT
4)     ALTER DATABASE ARCHIVE LOG
5)     ALTER DATABASE OPEN
