Red Hat Directory Server 8.0 Administrator's Guide

• Maximum LDAP connection(s). Maximum number of LDAP connections that the database

link establishes with the remote server. The default value is 10 connections.

• Maximum bind retries. Number of times a database link attempts to bind to the remote

server. A value of 0 indicates that the database link will try to bind only once. The default

value is 3 attempts.

• Maximum operations per connection. Maximum number of outstanding operations per

LDAP connection. The default value is 2 operations per connection.

• Connection lifetime (sec). How long a connection made between the database link and

remote server remains open. Connections between the database link and the remote

server can be kept open for an unspecified time or closed after a specific period of time. It

is faster to keep the connections open, but it uses more resources. For slow connections, it

may be desirable to limit the connection time. A value of 0 indicates there is no limit. By

default, the value is set to 0.
