I will note that if you are going to use slowaris, I highly advise you set
a memory key rather than using on disk cache for BDB if your DB is any size over about 4 GB. Other than that, you'll generally just have to deal with the fact it will be significantly slower than Linux.
Actually, you should always use a shared memory key on Solaris. Using mmap'd files is just too slow on that OS.
Incidentlly, What is the uniqueness of a shared memory key, is it unique amoung all instances on a single server ?
I have personally only ever needed a shared memory key on one of a group of ldap servers.
But i noticed that the bdb logs are not written to disk when shared memory is configured, is this a good or bad thing ?
If the power is lost, without bdb logs, could this leave bdb in an unrecoverable state ?
