Table Summarizing Tracing for webMethods EntireX Components

Tracing EntireX Broker

To switch on tracing

• Set the attribute TRACE-LEVEL in the broker attribute file

  • for minimal trace output to "1"

  • for detailed trace output to "2"

  • for full trace output to "3"

  Example:

  TRACE-LEVEL=2

To switch off tracing

• Set the attribute TRACE-LEVEL in the broker attribute file to 0:

  TRACE-LEVEL=0

  Or:
  Omit the TRACE-LEVEL attribute.

To display the trace file (under UNIX)

• In System Management Hub, select EntireX n.n.n, then EntireX Broker, then the Broker ID you are interested in, then choose Show Log File.

Trace Output

The trace file, BrokerID.LOG, is written to the Broker Directory directory.

Tracing Broker Agent

To switch on tracing

• Set the parameter Trace Option to ON. For the complete table of parameters, see Using the SSL Agent and Using the TCP Agent.

To switch off tracing

• Set the parameter Trace Option to OFF.

  Or:
  Omit the parameter Trace Option.

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.

To switch on tracing for the broker stub

• Before starting the client application, set the environment variable ETB_STUBLOG:

  Trace Value	Trace Level	Description
  0	NONE	No tracing.
  1	STANDARD	Traces initialization, errors, and all ACI request/reply strings.
  2	ADVANCED	Used primarily by system engineers, traces everything from level 1 and provides additional information - for example the Broker ACI control block - as well as transport information.
  3	SUPPORT	This is full tracing through the stub, including detailed traces of control blocks, message information, etc.

  Example:

  ETB_STUBLOG=2

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.

To switch off tracing for the broker stub

• Set the environment variable ETB_STUBLOG to NONE or delete it.

Tracing Enterprise JavaBeans

To switch on tracing

• Set entry name Trace (see Environment Entries to Control EJB)

  • for minimal trace output to "1"

  • for detailed trace output to "2"

  • for full trace output to "3".

To switch off tracing

• Set entry name Trace to "0".

  Or:
  Omit the entry name Trace.

Trace Output

The trace output will be written to STDOUT.

To change the directory and name of the trace destination

• Set the entry name Logfile to a valid file name, depending on your operating system.

Logging Enterprise JavaBeans

To switch on logging

• Set entry name Verbose to true. (See Environment Entries to Control EJB.)

To switch off logging

• Set entry name Verbose to false.

  Or:
  Omit the entry name Verbose.

Log Output

The log output will be written to STDOUT.

Tracing EntireX Java ACI

The EntireX Java ACI provides a system property for tracing.

To switch on tracing

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

   • for minimal trace output to "1"

   • for detailed trace output to "2"

   • for full trace output to "3".

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.

To switch off tracing

• Set the Java system property entirex.trace to 0 when starting the Java virtual machine

  Or:
  Omit the Java system property entirex.trace when starting the Java virtual machine.

Trace Output

The trace output will be written to STDOUT.

Tracing Java RPC Server

To switch on tracing

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

  • for minimal trace output to "1"

  • for detailed trace output to "2"

  • for full trace output to "3".

  See Customizing the Java RPC Server.

To switch off tracing

• Set the Java system property entirex.trace to "0" when starting the Java virtual machine.

  Or:
  Omit the Java system property entirex.trace when starting the Java virtual machine.

Trace Output

The trace output will be written to STDOUT.

Tracing the RPC Runtime

To switch on tracing

• Before starting the client application, set the environment variable ERX_TRACELEVEL to

  • STANDARD for minimal trace output

  • ADVANCED for detailed trace output

  • SUPPORT for full trace output.

To switch off tracing

• Set the environment variable to NONE or delete it.

Trace Output

By default the trace file, ERXTrace.nnn.log, will be written to the trace directory.

The value nnn can be in the range from 001 to 005.

To change the trace destination

• Set the environment variable ERX_TRACEFILE to the desired destination, which can consist of

  file names, folder names and variables for file names, folder names, process ID, thread ID, range.

  The variables are:

  Variable	Operating System	Description
  %...%	Windows	environment variable
  $(...)	UNIX	environment variable
  @PID	UNIX, Windows	process ID
  @TID	UNIX, Windows	thread ID
  @RANGE[ n,m ]	UNIX, Windows	m must be greater than n, range is from 0 - 999
  @CSIDL_PERSONAL	Windows	The user's home directory. The variable will be resolved by Windows shell functions.
  @CSIDL_APPDATA	Windows	The Application Data Directory. The variable will be resolved by Windows shell functions.
  @CSIDL_LOCAL_APPDATA	Windows	The Application Data Directory. The variable will be resolved by Windows shell functions.

Tracing the RPC Server

To switch on tracing

• Set the TraceLevel parameter in the server configuration file to

  • STANDARD for minimal trace output

  • ADVANCED for detailed trace output

  • SUPPORT for full trace output.

  See Configuring the RPC Server.

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

To switch off tracing

• Set the TraceLevel parameter in the server configuration file to NONE.

Trace Output

By default the trace file, ERXTrace.nnn.log, will be written to the trace directory.

The value nnn can be in the range from 001 to 005.

To change the trace destination

• Set the parameter TraceDestination in the server configuration file to the desired destination. See Configuring the RPC Server.

  The variables are:

  Variable	Operating System	Description
  %...%	Windows	environment variable
  $(...)	UNIX	environment variable
  @PID	UNIX, Windows	process ID
  @TID	UNIX, Windows	thread ID
  @RANGE[ n,m ]	UNIX, Windows	m must be greater than n, range is from 0 - 999
  @CSIDL_PERSONAL	Windows	The User's Home Directory. The variable will be resolved by Windows shell functions.
  @CSIDL_APPDATA	Windows	The Application Data Directory. The variable will be resolved by Windows shell functions.
  @CSIDL_LOCAL_APPDATA	Windows	The Application Data Directory. The variable will be resolved by Windows shell functions.

Tracing the XML/SOAP Runtime

This section provides information on tracing the following components:

• EntireX XML/SOAP RPC Server

• EntireX XML/SOAP Listener

• EntireX XML/SOAP Wrapper

The following topics are covered:

• Enabling Tracing

• Disabling Tracing

• Configuring a Trace File for the XML/SOAP Listener

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

• Trace Parameters

• Component Names

Enabling Tracing

There are two ways to switch on tracing mode:

• Using a Property File
• Using Trace Parameters of the Java Virtual Machine

Using a Property File

To switch on tracing mode using a property file

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

   • the working directory of your client application;

   • the user's home directory;

   • any other location.

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

To switch on tracing mode by specifying the trace parameters of the Java virtual machine

• Submit the trace parameters when you start the Java virtual machine for the application to be traced. See Trace Parameters. Note that parameter specifications submitted overwrite settings in the property file.

Disabling Tracing

To switch off tracing

• Delete or rename the trace property file if it is located in the working directory or in the user's home directory.

  Or:
  Specify level=NONE when invoking the Java virtual machine :

  java -Dentirex.sdk.default.trace.level = NONE MyClient

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.

Component Names

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

Tracing the EntireX RPC-ACI Bridge

To 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:

   • 0 to switch off tracing.

   • 1 to trace Broker calls.

   • 2 to trace Broker calls and the payload.

   • 3 to trace Broker calls and all buffers including the payload.

2. Redirect the trace to a file with the property entirex.server.logfile. Set this to the file name of the log file, the default is standard output.
