process_config

The process_config table stores information about each process instance that is defined on the system.

Multiple instances of each server process can be used to optimize iProcess Engine efficiency - for example, to increase the processing capability on one server, or to spread the processing load across multiple servers.

Structure

The process_config table has the following structure:

TABLE process_config(
logical_machine_id
INTEGER
NOT NULL,
logical_process_name
VARCHAR(10)
NOT NULL,
logical_process_instance
INTEGER
NOT NULL,
enabled
SMALLINT
NOT NULL,
persistent
SMALLINT
NOT NULL,
last_known_status
VARCHAR(20)
NOT NULL,
status_comment
VARCHAR(255)
NULL)

Column	Description
logical_machine_id	ID of the server where this process instance runs, as defined in the node_cluster table.
logical_process_name	Logical name of this process instance. Note: For a list of logical process names, see the "Administering iProcess Engine Server Processes" topic in TIBCO iProcess Engine Administrator's Guide.
logical_process_instance	Unique ID for this process instance.
enabled	Flag that defines whether this process instance starts automatically (1) when the iProcess Engine starts, or whether it must be started manually (0).
persistent	Flag that defines whether this process instance is automatically restarted (1) or not (0) when the iProcess Engine is shut down and restarted. Note: Any row in which the persistent value is 0 is deleted when the iProcess Engine starts up.
last_known_status	Last known status of this process instance, as reported to the Process Sentinels by the process. Either: STARTING, RUNNING, PAUSED, SUSPENDED, SHUTTING DOWN or STOPPED. Note: The process_event_log table provides an audit trail of changes to the status of a process instance.
status_comment	Brief explanation of the last_known_status, as reported to the Process Sentinels by the process.

Table Activity

The process_config table contains one row for each instance of each server process defined on the system.

Rows are added, updated, and deleted in the following situations.

A row is...	When...
added	a new process instance is added, either at installation or by using the SWDIR\util\swadm, SWDIR\util\swsvrmgr utilities.
updated	a process instance’s settings or status are updated, either by system activity, or by using the SWDIR\util\swadm or SWDIR\util\swsvrmgr utilities.
deleted	a process instance is deleted, either at installation or by using the SWDIR\util\swadm or SWDIR\util\swsvrmgr utilities.
