Tracing Broker Agent

Start of instruction setTo switch on tracing

Trace Output

The trace output will be written to STDOUT.

If the Broker Agent is started with the System Management Hub, the trace output is written to the subfolder etc of the EntireX main directory. The file name is BrokerAgent.<agent name>.log.

Tracing Broker Stubs

The broker stubs provide an option for writing trace files.

Start of instruction setTo switch on tracing for the broker stub

If the trace level is greater than 1, unencrypted contents of the send/receive buffers may be exposed in the trace.

The trace file is created in the current directory. The name is pid.etb where pid is the process ID. If you want to write the trace file to a different location, set environment variable ETB_STUBLOGPATH to the desired path.

See also UNIX Commands to Set the Environment Variables.

Remember to switch off tracing to prevent trace files from filling up your disk.

Tracing EntireX Java ACI

The EntireX Java ACI provides a system property for tracing.

Start of instruction setTo switch on tracing

  1. When starting the Java virtual machine, set the Java system property entirex.trace

  2. The programming interface of the EntireX Java ACI allows you to set the trace value by the Java application using the EntireX Java ACI, see Tracing under Writing Advanced Applications - EntireX Java ACI. There may also be other methods to provide the trace value. See your application documentation.

Tracing can also be switched on and off with the environment variable ERX_TRACELEVEL. The settings in the configuration file override the environment variable.

Tracing the XML/SOAP Runtime

This section provides information on tracing the following components:

The following topics are covered:

Enabling Tracing

There are two ways to switch on tracing mode:

Using a Property File

Start of instruction setTo switch on tracing mode using a property file

  1. Copy the trace property file entirex.trace.standard to one of the following locations:

  2. Rename the copied file entirex.trace.properties.

  3. Customize entirex.trace.properties as described in Trace Parameters.

  4. If entirex.trace.properties is within the current directory of your client application or your user home directory, it will be located automatically.

    Otherwise, specify the fully qualified or relative file name when starting the Java virtual machine for your client application using property entirex.sdk.default.trace.propertiesfile, example:

    java -Dentirex.sdk.default.trace.propertiesfile ="/MyDirName/entirex.trace.properties" MyClient

Using Trace Parameters of the Java Virtual Machine

Start of instruction setTo switch on tracing mode by specifying the trace parameters of the Java virtual machine

Disabling Tracing

Start of instruction setTo switch off tracing

Configuring a Trace File for the XML/SOAP Listener

We recommend to add the following parameter in file conf/axis2.xml located in the Software AG Common Web Services Stack installation:

<parameter name="exx-trace-propertiesfile">file:////path of trace.properties file</parameter>

Example:

<parameter name="exx-trace-propertiesfile">MyDirName/entirex.trace.properties</parameter>

Notes:

  1. If a relative path is specified, the file is located in directory WEB-INF/conf/ in the Web Services Stack web application file that contains the property.
  2. In the parameter section of the file axis2.xml, the value of the parameter exx-trace-propertiesfile can contain definitions of operating system variables, for example location="$EXXDIR/config/entirex.trace.properties".

Configuring a Trace File for the XML/SOAP Wrapper or the XML/SOAP RPC Server

See Enabling Tracing.

Note:
If the XML/SOAP RPC Server is running as a daemon, enable tracing by adding a Java system property to the start script or by copying file entirex.trace.properties to the same directory as the start script.

Trace Parameters

The following table provides an overview on trace parameters, their respective values, and how to submit them as arguments when invoking the Java virtual machine for the component to be traced.

Parameter Syntax Description
propertiesfile entirex.sdk.component name.trace.propertiesfile= absolute or relative path including the properties file Provide the location of the entirex.trace.properties file. Only used when the component is started.

Note:
A sample trace property file named entirex.trace.standard with predefined trace settings is contained in the directory ../EntireX/config. This file is a model and must be renamed to the valid name when used.

level entirex.sdk.component name.trace.level = tracelevel You can specify the following trace levels:
Keyword Level Description
NONE No tracing Tracing is switch off
STANDARD User Trace invocation of a component.
ADVANCED Expert For support and diagnostics. Expert knowledge of the component is required.
SUPPORT Expert Full trace output. Otherwise, as above.
directory entirex.sdk.component name.trace.directory = absolute or relative path Default is the working directory.
filename entirex.sdk.component name.trace.filename = FILE|STDOUT|STDERR Specify where tracing data is written to:
Keyword Destination
STDOUT (Default) Console
STDERR Console
FILE File name is generated internally: exx.sdk.component name.threadName. backupNo.log , where backupNo is in the range from ".000" to ".009". Note that the number of files created depends on maximumsize. If more than 10 files are required, the oldest backup file is overwritten.
threadoriented entirex.sdk.component name.trace.threadoriented = true | false
Keyword Description
YES Thread-oriented: trace data is distributed over multiple files (one file per thread)
NO (Default) Trace data is written to one file.
rowlength entirex.sdk.component name.trace.rowlength = maximum_characters_per_row Maximum number of characters per row. If this limit is exceeded, the remaining letters are written to a new line.
maximumsize entirex.sdk.component name.trace.maximumsize = max_file_size Maximum size of the log file. If this limit is exceeded, the log file is renamed and the remaining data is written to a new log file, see filename. Note that this specification has an effect only if filename is set to "FILE".
timeframe entirex.sdk.component name.trace.timeframe = number of day Time period after which the log file is closed. If this time limit has exceeded, the log file is renamed and the remaining data (if any) is written to a new log file. Note that this specification has an effect only if filename is set to "FILE". You can specify the following timeframes:
Keyword Description
1-9+H Number of hours
1-9+D Number of days

If no time frame is defined, only one log file is used until tracing is stopped.

Example: If timeframe has been set to 30D, the current log file is closed and renamed at midnight every thirty days, and tracing is continued with a new log file.

Component Names

Trace properties given in the trace property file might have to be restricted by componentname. The following components are available:

EntireX Component componentname Description
  default The trace property is not restricted to a specific EntireX component.
XML/SOAP Runtime xml.runtime The trace property belongs to the EntireX XML/SOAP Runtime only.

Tracing the EntireX RPC-ACI Bridge

Start of instruction setTo trace Broker calls

  1. Use the system property entirex.trace=[0|1|2|3].

    This trace does not separate the calls to the Broker for RPC from those to the Broker for ACI. The trace levels are:

  2. Redirect the trace to a file with the property entirex.server.logfile. Set this to the file name of the log file.
