Folks,

Is there a way out. (2 Replies)

Thanks a lot (3 Replies)
Hello Friends,
On one of my Solaris 10 box, CPU usage shows 100% using "sar", "vmstat". However, it has 4 CPUs and prstat and glance are not showing enough processes to justify high CPU utilization.

I'm running on Solaris 10, and I have a script that's running on several machines. Basically, what it's doing is:
* tail -f | grep one or more log files into a temp file
* Every minute or so, copy that temp file to a second temp and zero the first
* Sed through the 2nd temp to pull out a user... (2 Replies)

Got two RHEL servers - one real and one virtual/cloud.
Both run apache web server.
When traffic is applied, CPU seems to go quite high on virtual one (20%) but real is not really affected. Worry is that a further increase in traffic will see a problem.
Experience of RHEL is limited. Whats... (2 Replies)
We have a single threaded application which is restricted by CPU usage even though there are multiple CPUs on the server, hence leading to significant performance issues. Is it possible to merge / combine multiple CPUs at OS level so it appear as a single CPU for the application? (6 Replies)

I would try to find out the load spike of memory utilization in the Servers before 2-3 hours ago., As the alerts are being triggering out by the altering system.

VIRTUAL(3) 1 VIRTUAL(3)virtual - Perform an Apache sub-requestSYNOPSIS
bool virtual (string $filename)
DESCRIPTION virtual(3) is an Apache-specific function which is similar to <!--#include virtual...--> in mod_include. It performs an Apache sub-request.
It is useful for including CGI scripts or .shtml files, or anything else that you would parse through Apache. Note that for a CGI script,
the script must generate valid CGI headers. At the minimum that means it must generate a Content-Type header.
To run the sub-request, all buffers are terminated and flushed to the browser, pending headers are sent too.
This function is supported when PHP is installed as an Apache module or by the NSAPI server module in Netscape/iPlanet/SunONE webservers.
PARAMETERS
o $filename
- The file that the virtual command will be performed on.
RETURN VALUES
Performs the virtual command on success, or returns FALSE on failure.
EXAMPLES
See apache_note(3) for an example.
NOTES
Warning
The query string can be passed to the included file but $_GET is copied from the parent script and only $_SERVER['QUERY_STRING'] is
filled with the passed query string. The query string may only be passed when using Apache 2. The requested file will not be listed
in the Apache access log.
Note
Environment variables set in the requested file are not visible to the calling script.
Note
This function may be used on PHP files. However, it is typically better to use include(3) or require(3) for PHP files.
