The file that controls the configuration settings for Perspectium DataSync Agent is the agent.xml file. This file is automatically created within the Agent's bin directory upon installation. To make changes to the configuration settings for your DataSync Agent, open this agent.xml file in a text editing application and modify the directives described in the sections below.
Agent Level
The <agent> is the second highest level next to <config>. The agent level holds the job types to be executed (i.e <share> and <subscribe>), as well as optional directives for additional configurations. These directives will then contain their own configurations within.
| Directive | Description | Example Value |
|---|---|---|
| <max_reads_per_connect> | Maximum number of messages to consumer per connection interval. | 4000 |
| <max_writes_per_connect> | Maximum number of messages to produce per connection interval. | 4000 |
Interval for how often the agent pulls from the queue (seconds).
| 5 | |
| <skip_message_set_processing/> | Self-closing tag that disables Message Set posting for data shared from ServiceNow. | |
| <skip_table_stats/> | Self-closing tag that disables tracking of changes to replicated tables. Without this directive, the changes would be found in psp_table_stats tables in the psp_db table on MBS. For earlier versions (Fluorine+ and below), this directive is required for Snowflake database. | |
| <share> | An Agent configured with <share> functionality (also known as a producer) monitors static data sources and places messages from those sources into queues in the Perspectium Mesh. | |
| <subscribe> | An Agent configured with <subscribe> functionality (also known as a consumer) monitors queues in the Perspectium Mesh and processes any messages in those queues, typically by routing those messages to a static data source.
| |
| <skip_report/> | Self-closing tag that causes the agent to skip sending reporting messages. |
NOTE: Subscribe & Share Level
There are two types of handlers or tasks that can be configured within the <agent> tag, the subscriber <subscribe> and the sharer <share>. The subscribe or share level will have zero or more nested <task> elements. However, the DataSync Agent will always have at least one task to perform the replication.
| Directive | Description |
|---|---|
| <task> | Task that handles either sharing or subscribing. You can configure separate settings by defining directives within each <task> directive. You can also specify an instances attribute here and give it a value of 4 (default) so that 4 instances of your <share> or <subscribe> task can run concurrently, thus improving throughput for data processing.
|
Task Level
The <task> level specifies the configurations needed for connecting to the instance, server, and database along with optional directives that allows for more control and configurations.

| |||||||||||||||||||||
| <database_sid> | SID used for your Oracle database

| <ensure_table_exists/> | Self-closing tag that is required for replicating to Snowflake database. |
