Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Search for | Example | Results |
---|---|---|
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 |
|
|
Either word in a topic |
|
|
Topics that do not contain a specific word or phrase |
|
|
Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
A combination of search types | ( ) parentheses |

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?
No
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.
