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 |

Troubleshooting RESTful API
This section provides information about how to troubleshoot RESTful API issues.
Debugging parameters
The following three parameters are most frequently used for debugging RESTful API:
-
debugrest
Add debugrest in sm.ini or in the dedicated servlet container line of the sm.cfg file, restart the Service Manager and re-run the RESTful Web service application to invoke debugging parameter. It provides more detailed log trace for diagnostics.
-
dao_threadsperprocess
Similar to debugrest, it can be set in sm.ini or in the dedicated servlet container line of sm.cfg file.
It means the maximum number of threads allowed concurrently running in the process for RESTful Web Service application. It can be defined in sm.ini and the default value is 10. It is better to start enough server threads to handle requests (suggest to maintain the buffer of 30%~ 40% spare capacities).
-
dao_sessiontimeout
Like debugrest, the dao_sessiontimeout parameter can be set in sm.ini or in the dedicated servlet container line of sm.cfg file.
It indicates the seconds to wait before terminate the RESTful threads. It can be defined in sm.ini and the default value is 15 seconds. Unless the client sends subsequent requests within the timeout, the Service Manager server will recycle the session for re-use and re-allocate it on demand.
If there is big divergence, it is recommended to connect several servlets with different thresholds.
It is also useful to use the msglog:1 parameter to have all messages written to the sm.log as well.
Web services with a proxy server
If you are using web services with a proxy server, incorrect proxy server settings will cause your web service calls to fail. For details, see Web Services with a proxy server.
