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 |

Scheduled Maintenance overhead
Scheduled Maintenance relies on the problem background scheduler to call into the Scheduled Maintenance code at regularly scheduled intervals. If the problem scheduler is not running, no Scheduled Maintenance tasks run. When a Scheduled Maintenance task runs, it increases the load on the problem scheduler by a marginal amount.
Scheduled Maintenance does not put a large load on your system unless you are using the Scheduled Maintenance system to generate extraordinarily large numbers of incident records, change requests, or
If a Scheduled Maintenance task creates 20,000 Incident records at 2:00 AM, the task would slow the Service Manager system down somewhat. Scheduled Maintenance creates all 20,000 records consecutively, as though one user were opening 20,000 incident records consecutively. The increased load may be noticeable, but it will not be crippling.
Load balancing
You should not notice any change in your system load when you use Scheduled Maintenance. However, if you have an unusually large number of tasks opening every day, such as 1000 each day, or over 100 in a 10-minute period, consider creating a private scheduler that runs only Scheduled Maintenance tasks. When you create and run this scheduler, change the class on the Scheduled Maintenance Hook record to match your new scheduler. You can also change the repeat interval on the inhook schedule record.
Access the Scheduled Maintenance Hook record
Applies to User Roles:
System Administrator
To access the Scheduled Maintenance Hook record:
- Click Tailoring > Database Manager.
- Type schedule.looksee in the Form field.
- Type schedule in the Table field.
- Click the large Search icon.
- Click Search.
- Click the Scheduled Maintenance Hook record to view it in the Schedule File form.
Note: The minimum effective repeat interval is one minute. This interval causes the server to check for tasks every minute. With adjustment, you can reduce this to about 10 seconds. You cannot reduce the interval to less than 10 seconds because of the internal structure of the Service Manager scheduling system.
