Redo Log File Error

Hi, I've been getting the following message in by lgwr.trc file:

...

Advanced to log sequence 5815 file /usr/local/oracle/dbs/log1P.dbf Advanced to log sequence 5816 file /usr/local/oracle/dbs/log2P.dbf Mon Jun 15 01:13:04 1992
cannot allocate new log, seq 5817, needs checkpointing Advanced to log sequence 5817 file /usr/local/oracle/dbs/log1P.dbf
...

I imagine that I need to either add another log-file, increase the size of the files, or decrease the log_checkpoint_interval variable. I have the default log-files right now: 2 of 500K. All my log-variables in INIT.ORA are defaults. I've read and mostly understood the chapters regarding Redo Logs in the DBA Manual, but was wondering if anyone else has any friendly words of advice, before I start changing things.

Thanks in advance, please post or email.
