cn=config
27
Parameter Description
Syntax DirectoryString
Example nsslapd-config: cn=config
2.3.1.38. nsslapd-conntablesize
This attribute sets the connection table size, which determines the total number of connections
supported by the server.
The server has to be restarted for changes to this attribute to go into effect.
Parameter Description
Entry DN cn=config
Valid Values Operating-system dependent
Default Value The default value is the system's max
descriptors, which can be configured using
the
Section 2.3.1.77, “nsslapd-maxdescriptors
(Maximum File Descriptors)”
attribute.
Syntax Integer
Example nsslapd-conntablesize: 4093
Increase the value of this attribute if Directory Server is refusing connections because it is out of
connection slots. When this occurs, the Directory Server's error log file records the message
Not
listening for new connections -- too many fds open
.
A server restart is required for the change to take effect.
It may be necessary to increase the operating system limits for the number of open files and number
of open files per process, and it may be necessary to increase the
ulimit
for the number of open
files (
ulimit -n
) in the shell that starts the Directory Server. See
Section 2.3.1.77, “nsslapd-
maxdescriptors (Maximum File Descriptors)”
for more information.
2.3.1.39. nsslapd-counters
The
nsslapd-counters
attribute enables and disables Directory Server database and server
performance counters.
There can be a performance impact by keeping track of the larger counters. Turning off 64-bit integers
for counters can have a minimal improvement on performance, although it negatively affects long term
statistics tracking.
This parameter is enabled by default. To disable counters, stop the Directory Server, edit the
dse.ldif
file directly, and restart the server.
Parameter Description
Entry DN cn=config
Valid Values on | off
Default Value on
Syntax DirectoryString
Example nsslapd-counters: on
