Red Hat Directory Server 8.0 Administrator's Guide

Attribute Name Description
nsConcurrentOperationsLimit Maximum number of outstanding operations
per LDAP connection. The default value is 2
operations per connection.
nsConcurrentBindLimit Maximum number of outstanding bind
operations per TCP connection. The default
value is 10 outstanding bind operations.
nsBindRetryLimit Number of times a database link attempts to
bind to the remote server. A value of zero (0)
indicates that the database link will try to bind
only once. The default value is 3 attempts.
nsConnectionLife Connection lifetime, in seconds. 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 example, it may be
wise to limit the connection time for a slow
connection. A value of 0 indicates there is no
limit. By default, the value is set to 0. When
the value is 0 and there is a list of failover
servers in the nsFarmServerURL attribute, the
first server is never contacted after failover to
the alternate server. The default value is 0
seconds.
nsBindTimeout Amount of time, in seconds, before the bind
attempt times out. The default value is 15
seconds.
nsAbandonedSearchCheckInterval Number of seconds that pass before the
server checks for abandoned operations. The
default value is 1 seconds.
Table 3.5. Database Link Connection Management Attributes
For the list of database link configuration attributes, see Table 3.4, “Database Link Configuration
Attributes”.
3.6.2. Detecting Errors During Normal Processing
Protect server performance by detecting errors during the normal chaining operation between
the database link and the remote server. The database link has two attributes —
nsMaxResponseDelay and nsMaxTestResponseDelay — which work together to determine if
the remote server is no longer responding.
