How to Modify the Maximum Number of Threads for the Data-In Service

Since UCMDB 10.30, the Data-In service can process multiple CI buckets concurrently if they do not intersect based on their identification. If two CIs from two buckets are identified with each other, then the Data-In service processes the two buckets sequentially.

By default, the Data-In service can process four CI buckets concurrently. You can modify this number according to the server's capability: increase the number if the server is powerful and decrease the number if otherwise.

To modify the maximum number of threads for the Data-In service, follow these steps:

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	`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)`

Extract the <UCMDB_Server_Home>\lib\reconciliation.jar\services\reconciliation\service-config.xml file to the following folder:

<UCMDB_Server_Home>\conf\service-config\services\reconciliation\

Locate the following section in the extracted service-config.xml file:

<task-config total-threads-num="4" max-queue-size="30">
    <manager-creation>
        <manager-factory-class-name>com.hp.ucmdb.reconciliation.datain.manager.DataInManagerFactory</manager-factory-class-name>
    </manager-creation>
</task-config>

Modify the value of total-threads-num from 4 to your desired value, and then save the file.

Note The recommended values are from 1 to 8.

Restart the UCMDB server.
