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.
Words and Phrases
| 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. |
Using Boolean Operators
| 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 |

Example: Configuring the Apache web server to forward requests to Tomcat
To configure the Apache web server to forward requests to Tomcat, complete the following tasks.
Task 1: Install the mod_jk binary in the correct folder
- Obtain the binary version of mod_jk here.
- Extract the downloaded .zip file, and then put the
mod_jk.sofile to the/modulesdirectory in the Apache installation.
Task 2: Add settings to the httpd configuration file
Add the following lines to the httpd.conf file in the /conf directory:
# Load mod_jk module LoadModule jk_module modules/mod_jk.so # Where to find workers.properties JkWorkersFile conf/workers.properties # Where to put jk shared memory JkShmFile logs/mod_jk.shm # Where to put jk logs JkLogFile logs/mod_jk.log # Set the jk log level [debug/error/info] JkLogLevel info # Set the wildcard to forward to tomcat JkMount /webtier/* worker1
Task 3: Add settings to the httpd configuration file
Create a workers.properties file in the /conf directory and put the following content in the file:
worker.list=worker1,jkstatus #Set properties for worker1 (ajp13) worker.worker1.type=ajp13 worker.worker1.host=hpsmucmdb.in.vm worker.worker1.port=8009 worker.worker1.ping_timeout=1000 worker.worker1.connect_timeout=10000 worker.worker1.prepost_timeout=10000 worker.worker1.socket_timeout=10 worker.worker1.connection_pool_timeout=60 worker.worker1.connection_pool_size=90 worker.worker1.retries=2 worker.worker1.reply_timeout=300000 # status worker worker.jkstatus.type=status
This setup is for forwarding requests to a single worker Tomcat. If more than one Tomcat instance is required on the same server, the following changes are required:
-
Worker name in worker.properties
-
AJP Port configuration aligned between worker.properties and the server.xml file in Tomcat
-
A lb statement in workers.properties
