generate system tuning recommendations for running Directory Server Enterprise Edition server software
Synopsis
./idsktune [-q] [-D] [-v] [-c] [-i install-path]
Description
The idsktune
command checks patch levels and kernel parameter settings for the system on which Directory Server or directory client applications run, making tuning recommendations as it performs the checks.
Caution:
Information given by idsktune
may not apply to the current version or platform upon which it is run.
Run the command as super user to obtain the widest range of tuning recommendations.
The idsktune
command is delivered only with the zip distribution software.
The idsktune
command suggests changes you make to the system, but does not itself make any changes. You must fix at least all ERROR
conditions identified by the idsktune
command.
The idsktune
command reports as missing all patches recommended at the time of release and not installed on the system, even patches for packages not installed on the system.
Options
The idsktune
command supports the following options.
-c
Display tuning recommendations only for directory client applications.
Default is to display recommendations for both directory client applications and for Directory Server.
-D
Run in debug mode, displaying messages to showing commands the idsktune
command runs internally, preceded by DEBUG
.
-i
install-pathCheck the specified installation directory to ensure enough space is available.
-q
Run in quiet mode, reporting only information about key system prerequisites and essential settings.
-v
Display the version information about the build and exit.
Extended Description
The idsktune
command verifies and reports on the following settings depending on the underlying system.
Solaris and Red Hat version numbers
Solaris kernel build date
Solaris, and HP-UX patches
Physical memory size
Swap space or swap partition size
Memory resource limits
File descriptor resource limits
Maximum threads per process for HP-UX
Maximum files for HP-UX
Many of the following are system-specific TCP tuning settings.
Listen backlog queue size
tcbhashsize
, tcbhashnum
and tcp_msl
sominconn
and somaxconn
ipport_userreserved_min
tcp_close_wait_interval
and tcp_time_wait_interval
tcp_keepalive_interval
tcp_max_listen
tcp_conn_request_max
tcp_conn_req_max_q
and tcp_conn_req_max_q0
tcp_rexmit_interval_initial
net.inet.ip.portrange.hifirst
and tcp_smallest_anon_port
tcp_slow_start_initial
net.inet.tcp.delayed_ack
and tcp_deferred_ack_interval
link_speed
on /dev/hme
Tuning system settings, especially network stack settings, involves considering potentially not just directory applications and Directory Server, but also other applications running on the system and in the environment. In general, however, implementing the recommendations optimizes directory performance whether the system is dedicated to Directory Server or shared with other applications.
Exit Status
The idsktune
command exits with status 0
if it completes successfully and no ERROR
s are found. Otherwise, it exists with non-zero status.
