Hello, guys !
Long time no seen. I have a question about Linux web servers. I guess it is a more general question, but in my case it is a Linux web server. I want to know how much RAM memory should I put on my servers. Do you have some formula or guidelines on how should I calculate the amount... (1 Reply)
hi,
currently we have SAP application running on a solaris machine that has 8 dual core CPUs @ 2.4 GHZ and the performance of the system is perfectly normal. We plan to migrate the app to a suse linux VM image on a vmware box now. So my questions are:
1) Should i size the linux image to... (2 Replies)
We have a system with 4 Xeon Processors each with 10 cores, total 512 GB RAM and 10 TB Hard Drive.
we want to create multiple user accounts with different resource limitations as :
User 1: RAM : 50GB, PROCESSOR: 10 Cores , User folder in home directory of 10GB space.
User 2: RAM :... (5 Replies)
Hi,
I will be creating a process myself and I want to know the average CPU and RAM used by the process over the lifetime of the process. I see that there are various tools available(pidstat) for doing , I was wondering if it possible to do it in a single command while creation.
Thanks in... (3 Replies)
Hi
i have 2 esxi. one is amd based cpu and the other is intel based cpu.

AMQ(8) System Manager's Manual AMQ(8)NAME
amq - automounter query tool
SYNOPSIS
amq [ -fmpqsvwHTU ] [ -h hostname ] [ -l log_file ] [ -x log_options ] [ -D debug_options ] [ -P program_number ] [[ -u ] directory ... ]
DESCRIPTION
Amq provides a simple way of determining the current state of amd program. Communication is by RPC. Three modes of operation are sup-
ported by the current protocol. By default a list of mount points and auto-mounted filesystems is output. An alternative host can be
specified using the -h option.
If directory names are given, as output by default, then per-filesystem information is displayed.
OPTIONS -f Ask the automounter to flush the internal caches and reload all the maps.
-h hostname
Specify an alternate host to query. By default the local host is used. In an HP-UX cluster, the root server is queried by default,
since that is the system on which the automounter is normally run.
-l log_file
Tell amd to use log_file as the log file name. For security reasons, this must be the same log file which amd used when started.
This option is therefore only useful to refresh amd's open file handle on the log file, so that it can be rotated and compressed via
daily cron jobs.
-m Ask the automounter to provide a list of mounted filesystems, including the number of references to each filesystem and any error
which occurred while mounting.
-p Return the process ID of the remote or locally running amd. Useful when you need to send a signal to the local amd process, and
would rather not have to search through the process table. This option is used in the ctl-amd script.
-q Suppress error messages produced when attempting synchronous unmounts with the -u option.
-s Ask the automounter to provide system-wide mount statistics.
-u Ask the automounter to unmount the filesystems named in directory instead of providing information about them. Unmounts are
requested, not forced. They merely cause the mounted filesystem to timeout, which will be picked up by amd's main scheduler thus
causing the normal timeout action to be taken. If the -u option is repeated, amq will attempt to unmount the file system syn-
chronously by waiting until the timeout action is taken and returning an error if the unmount fails. Any error messages produced
may be suppressed with the -q option.
-v Ask the automounter for its version information. This is a subset of the information output by amd's -v option.
-w Translate a full pathname as returned by getcwd(3) into a short Amd pathname that goes through its mount points. This option
requires that Amd is running.
-x log_options
Ask the automounter to use the logging options specified in log_options from now on. Note that the "fatal" and "error" options can-
not be turned off.
-D debug_options
Ask the automounter to use the debugging options specified in debug_options from now on.
-H Display short usage message.
-P program_number
Contact an alternate running amd that had registered itself on a different RPC program_number and apply all other operations to that
instance of the automounter. This is useful when you run multiple copies of amd, and need to manage each one separately. If not
specified, amq will use the default program number for amd, 300019. For security reasons, the only alternate program numbers amd
can use range from 300019 to 300029, inclusive.
-T Contact amd using the TCP transport only. Normally amq will try TCP, and if that failed, will try UDP.
-U Contact amd using UDP (connectionless) transport only. Normally amq will try TCP, and if that failed, will try UDP.
FILES
amq.x RPC protocol description.
CAVEATS
Amq uses a Sun registered RPC program number (300019 decimal) which may not be in the /etc/rpc database.
If the TCP wrappers library is available, and the use_tcpwrappers global amd.conf option is set to ``yes'', then amd will verify that the
host running amq is authorized to connect. The amd service name must used in the /etc/hosts.allow and /etc/hosts.deny files. For example,
to allow only localhost to connect to amd, add this line to /etc/hosts.allow:
amd: localhost
and this line to /etc/hosts.deny:
amd: ALL
