For more information on database transaction logging, see chapter 12,
“Monitoring Server and Database Activity,” in the Red Hat Directory Server
Administrator’s Guide.
nsslapd-db-transaction-logging
Specifies whether transaction logging is on or off. Turning transaction logging off
can considerably improve Directory Server performance but at the risk of data
loss and/or database corruption in the event of a system crash. If turned off, it
would be necessary to set up other database recovery procedures.
nsslapd-db-trickle-percentage
Ensures that at least the specified percentage of pages in the shared-memory pool
are clean by writing dirty pages to their backing files. This is to ensure that a page
is always available for reading in new information without having to wait for a
write.
