For us, on 8.1.7.1 with 90MB redologs and about 120-150 connections (100-150
avg TPM), we get log switches every two hours during the day and about every
10-15 minutes during the nightly processing.  I guess ideal is to switch
every 30 minutes or so, but we needed to compromise because of the nightly
batches, so I went with a 90MB redo.

Good luck!

100mb for redo log file is not that big?  Not big if your environment is
heavy in OLTP.

Friends :

I am installing the database Oracle 9i.
And it have suggested a parameter value 100mb for redo log file.

I am confused with this value, i think it is too big.

The blocksize is 8192
Connections simultaneous is 100

Where am I doing any mistake ?
