- generate system tuning recommendations for running Directory Server Enterprise Edition server software
./idsktune [-q] [-D] [-v] [-c] [-i install-path]
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. 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.
The idsktune command supports the following options.
Display tuning recommendations only for directory client applications.
Default is to display recommendations for both directory client applications and for Directory Server.
Run in debug mode, displaying messages to showing commands the idsktune command runs internally, preceded by DEBUG.
Check the specified installation directory to ensure enough space is available.
Run in quiet mode, reporting only information about key system prerequisites and essential settings.
Display the version information about the build and exit.
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
tcp_close_wait_interval and tcp_time_wait_interval
tcp_conn_req_max_q and tcp_conn_req_max_q0
net.inet.ip.portrange.hifirst and tcp_smallest_anon_port
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.
The idsktune command exits with status 0 if it completes successfully and no ERRORs are found. Otherwise, it exists with non-zero status.
