Reference nJAMS Client for BW properties#

This is the reference of available nJAMS Client for BW properties:

Initialize nJAMS Client for BW#

Replace Java Start Class preset by TIBCO with Java Start Class of nJAMS Client for BW in order to initialize nJAMS Client for BW once the BW eninge starts.

Update BW engine TRA file by commenting original start class and adding njams start class:

# java.start.class=com.tibco.pe.PEMain
java.start.class=com.faizsiegeln.njams.client.run

General settings#

The following properties determine the general configuration of nJAMS Client for BW.

tibco.clientVar.nJAMS/logMode:

Globally controls the operation mode of the nJAMS Client for BW:

complete nJAMS Client for BW will monitor all processes that are executed within the TIBCO BusinessWorks engine (default).

exclusive nJAMS Client for BW will only monitor processes, that make explicit use of the nJAMS Client for BW palette. All other processes will be ignored.

none the nJAMS Client for BW functionality is completely disabled; event instrumented processes that are using the nJAMS Client for BW palette are not monitored.

tibco.clientVar.nJAMS/configurationFile:

Defines the path to a directory or file name where the configuration of this client is stored. Directory: If a directory is specified, nJAMS Client for BW will search for a file of name <ENGINE_NAME>_njams_config.xml. In case an individual config file does not exist in this directory, nJAMS Client for BW will search for the default config file of name njams_default_config.xml and use the content of this file as template for creating the individual config file. Absolute file name: if an absolute file name is specified, nJAMS Client for BW will use that file as its configuration file. Default is not specified.

tibco.clientVar.nJAMS/publishSources:

Controls whether to publish process definition or not. If no process definition is sent, there will be no process graph visible in nJAMS UI.

true publishes process definitions (default).

false does not publish process definitions.

tibco.clientVar.nJAMS/flushOnCheckpoint:

Controls how to proceed, when TIBCO BusinessWorks Checkpoint activity is executed.

true sends event message, when executing BW Checkpoint activity regardless of other nJAMS Client for BW settings (logMode, timeoutPush) (default).

false continues with respect of other nJAMS Client for BW settings.

tibco.clientVar.nJAMS/logAllErrors:

Controls when nJAMS Client for BW should send error events.

true automatically creates error events for catched and uncatched exceptions.

false automatically creates error events only for uncatched exceptions (default).

Sample settings for general configuration of nJAMS Client for BW:

tibco.clientVar.nJAMS/logMode=complete
tibco.clientVar.nJAMS/configurationFile=

Data Provider - EngineLog#

tibco.clientVar.nJAMS/DataProvider/EngineLog/enabled:

Enables or disables the writing of event messages into bw engine’s log file.

true nJAMS Client for BW writes event messages into bw engine’s log file.

false disables writing event messages into bw engine’s log file (default).

Data Provider - File#

tibco.clientVar.nJAMS/DataProvider/File/enabled:

Enables or disables the writing of event messages into log file.

true nJAMS Client for BW writes event messages into log file.

false disables writing event messages into log file (default).

tibco.clientVar.nJAMS/DataProvider/File/name:

Absolute path of the log file to write log entries to (if enabled). For example: /tmp/njams_events.log.

Memory Management#

See the following properties to adjust nJAMS Client for BW’s memory management:

tibco.clientVar.nJAMS/MemoryManagement/maxMsgSizeMB:

Maximum internal message size. If size of internal message is reached, an instant push is triggered. Enter any integer value > 0 in MB. Default is 10.

tibco.clientVar.nJAMS/MemoryManagement/maxQueueLength:

Maximum internal queue size, before discardPolicy is applied. Enter any integer value > 0. Default is 20.

tibco.clientVar.nJAMS/MemoryManagement/discardPolicy:

Discards messages from memory, when maxQueueLength is exceeded.

none blocks the engine until queue size is below threshold (default).

discard will discard of the message.

OnConnectionLoss only discards event messages, if there is no connection available to JMS or Cloud provider. Otherwise the engine is slowed down until all log messages are sent, respectively queue size is below threshold.

Sample settings for memory management:

# Memory manangement settings for usual scenarios:
tibco.clientVar.nJAMS/MemoryManagement/maxMsgSizeMB=10
tibco.clientVar.nJAMS/MemoryManagement/maxQueueLength=20
tibco.clientVar.nJAMS/MemoryManagement/discardPolicy=none

Log4j configuration#

nJAMS Client for BW uses the TIBCO BusinessWorks log4j configuration for its technical logging. By default, nJAMS logs into bw engine’s log file. You can use an individual logger for nJAMS Client for BW, if you want to log nJAMS message into a separate log file.

TIBCO BusinessWorks provides two locations, where you can configure Log4j. Depending of what you prefer, you can configure either log4j2.properties or log4j2.xml.

Both configuration files reside in <TIBCO_HOME>/bw/<VERSION>/lib.

Note

Starting with TIBCO BusinessWorks 5.15 TIBCO supports Log4j v2. The previous versions of TIBCO BusinessWorks support Log4j v1, which means the Log4j configuration filenames are accordingly log4j.properties, respectively log4j.xml.

In order to allow nJAMS Client for BW to log in its own separate log file, you have to add a log4j appender and a log4j logger into this configuration file. The following describes how Log4j can be configured in both ways.

  1. Add nJAMS logger to Log4j2 configuration file:

    By default, TIBCO BusinessWorks uses log4j2.properties for Log4j2 configuration.

    Use log4j2.properties:

    Modify <TIBCO_HOME>/bw/5.x/lib/log4j2.properties and add an additional appender and logger for nJAMS Client for BW, e.g.:

    # ============================================================================
# nJAMS appender.
appender.rolling.type = RollingFile
appender.rolling.name = njams_log
appender.rolling.fileName = /tmp/njams.log
appender.rolling.filePattern = /tmp/njams.log.%i
appender.rolling.policies.type = Policies
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size = 10MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 10
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %-5p %d [%t] [event: %X{correlationId}] %c: %m%n

# nJAMS Logger. The logger level is "INFO" and the appender is set to the
# nJAMS appender.
logger.njams.name = bw.logger.njams
logger.njams.level = INFO
logger.njams.appenderRef.bw_log.ref = njams_log
logger.njams.additivity = false

    Alternatively, you can use log4j2.xml:

    Modify <TIBCO_HOME>/bw/5.x/lib/log4j2.xml and add an additional appender and logger for nJAMS Client for BW, e.g.:

    <RollingFile name="njams_log" fileName="/tmp/njams.log" filePattern="/tmp/njams.log.%i">
    <PatternLayout pattern="%-5p %d [%t] [event: %X{correlationId}] %c: %m%n"/>
    <SizeBasedTriggeringPolicy size="10 MB"/>
    <DefaultRolloverStrategy max="10"/>
</RollingFile>

<logger name="bw.logger.njams" level="info" additivity="false">
    <AppenderRef ref="njams_log"/>
</logger>

    Also modify bw engine TRA file(s) in order to make use of the log4j2 configuration in log4j2.xml and add the following line at the bottom of the TRA file. For TIBCO Desginer you have to modify designer.tra file at <TIBCO_HOME>/designer/<VERSION>/bin/ accordingly.

    java.extended.properties=-Dlog4j.configurationFile=file:%TIB_HOME%/bw/5.15/lib/log4j2.xml

  2. Add the following property to your bw engine TRA file, to make use of this logger:

    tibco.clientVar.nJAMS/logger=bw.logger.njams

    In TIBCO Designer you can set value bw.logger.njams to global variable nJAMS/logger.

  3. Restart bw enigne, respectively TIBCO Designer, for the changes to take effect.

Subagent#

The following properties configure Subagent against nJAMS Agent service:

tibco.clientVar.nJAMS/Subagent/enabled:

Turn on/off Subagent.

true enables Subagent (default).

false disables Subagent.

tibco.clientVar.nJAMS/Subagent/host:

Name of the server that hosts nJAMS Agent service. Enter a hostname or ip-address, default is localhost.

tibco.clientVar.nJAMS/Subagent/port:

Port number of nJAMS Agent service, default is 6450.

Sample settings for Subagent:

# Enable Subagent and configure against nJAMS Agent on localhost:
tibco.clientVar.nJAMS/Subagent/enabled=true
tibco.clientVar.nJAMS/Subagent/host=localhost
tibco.clientVar.nJAMS/Subagent/port=6450

Quick sample configuration#

Please find below a sample configuration that enables nJAMS Client for BW in non-invasive mode while using TIBCO EMS. After applying the configuration to BW engine TRA file, you have to restart the BW engine.
