In the DataSync Agent, you can truncate table records in your database before sharing. Along with the DataSync application in ServiceNow, you can clear the records for a selected table in your database before bulk sharing by enabling Truncate Before Share.
Procedure
To truncate records for your DataSync integration, follow these steps:
Access your agent.xml configuration file
Navigate to the directory where you saved your agent.xml file when installing your DataSync Agent.
Add the truncate_table directive
Open your agent.xml file in a text editing application. Then, locate the <task> directive(s) and add <truncate_table>true</truncate_table>.
Save your agent.xml
Save the changes you've made to your agent.xml and close the file. Your agent.xml should look similar to the example shown below:
<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?> <config> <agent> <share/> <subscribe> <task instances="4"> <task_name>datasyncforservicenow_to_mysql_subscribe</task_name> <message_connection password="encrypted:vlOtU71yu8N/EFIJH85SSBtaIt7qEEfvqiqft9VZyYE=" queue="psp.out.replicator.testqueue" user="admin">https://testperspectium.net</message_connection> <instance_connection password="encrypted:vlOtU71yu8N/EFIJH85SSPN9aF0P5/YViVwPEVFcGW4=" user="test.user">https://myinstance.service-now.com</instance_connection> <handler>com.perspectium.replicator.sql.SQLSubscriber</handler> <decryption_key>The cow jumped over the moon</decryption_key> <database_type>mysql</database_type> <database_server>localhost</database_server> <database_port>3306</database_port> <database_user>root</database_user> <database_password>encrypted:vlOtU71yu8N/EFIJH85SSMoilKLTeJHQrNZPJ7c5tFU=</database_password> <database_parms>characterEncoding=UTF-8 & useSSL=false</database_parms> <database_column_max_size>251</database_column_max_size> <database>psp_repl</database> <truncate_table>true</truncate_table> </task> </subscribe> <max_reads_per_connect>4000</max_reads_per_connect> <polling_interval>5</polling_interval> <skip_message_set_processing/> </agent> </config>
Run your Agent
After configuring your agent.xml file, start running your DataSync Agent.
