A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Search for	Operator	Example
Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`
A combination of search types	`( )` parentheses	`cat + (dog \| mouse)` `cat \| dog + (! mouse)`

Service Manager9.41

Administer > System Configuration Parameters > Servlet parameters > Parameter: reportgroup

Parameter: reportgroup

Parameter

reportgroup

Description

This parameter displays the status of ports, processes, and threads in horizontal and vertical scaling servlet implementations.

Important: The reportgroup process requires every other process to send it a report. This means that every process must consume some amount of system memory to generate its report, which decreases the amount of memory available to run the system. While the reporting information may be valuable, you need to balance your data tracking requirements with the amount of memory being used. To reduce the performance impact of running this process, you may want to run it on a development or testing system, or choose a longer interval between running reports.

Note If you have opted to run this process continuously (for example, every minute non-stop), you have the option to shut down the process. To shut down a specific Service Manager process, specify the hostname of the Service Manager server and system process (PID) you want to shut down. On a command line, enter sm -shutdown -host:myhost.myserver.com -PID:1234.

Some examples of the information that is reported include:

Service Manager locks that are currently being held.
Service Manager threads waiting to acquire locks. This is useful for lock analysis.
Thread dumps of all Service Manager processes on all hosts. This is useful for detecting deadlocks, if any. Thread dumps repeat for each process and host.

The information is sent to a separate log file.

Settings

Server's operating system command prompt

Requires restart of the Service Manager server?

Default values

Run the report every 20 seconds.

Repeat the process 15 times.

Possible values

Number of seconds between reports and the number of times to run a report.

Example usage

Run the report every 20 seconds and repeat the process 15 times.

sm -reportgroup

sm -reportgroup:20,15

Recommended: Run the report every minute and repeat the process 20 times. This provides less load on the cluster.

sm -reportgroup:60,20

Log File Examples

The following sample is an example of the information that is displayed in a log file for a vertical scaling servlet implementation on one host.
