# 2.4 Tracing Device Communications

The DAS for AB INTERCHANGE software has built into it the capability to trace INTERCHANGE software communications and to send this output to either a file, a user terminal or to the BASEstar Classic history file. The purpose of this tracing is to allow the troubleshooting of INTERCHANGE software communications and is intended to be used primarily under the direction of support personnel.

To enable tracing to send trace information to a file do the following:

- Set the following logical to 1:

  DCM_DTL$SRV_TRACE | Trace the DCM_DTL$SRV process(es)

  The logical name must be defined in a scope that will be seen by the associated server process (DCM_DTL$SRV_n).
- Set the corresponding output logical to a file or other output device:

  DCM_DTL$SRV_TRACE_OUTPUT_n | Trace the DCM_DTL$SRV process "n"

  The logical name must be defined in a scope that will be seen by the associated server process (DCM_DTL$SRV_n).
- Start the tracing.
  To start the tracing for the DCM_DTL$SRV process, stop the associated server process and restart it. The trace logicals are read only at process startup.

The trace output is flushed to the file after every 100 lines that are traced, so trace output may lag actual device I/O.

To turn tracing off, reverse the steps used to turn tracing on.

# 2.5 Failures During Product Use

If an error occurs while this product is in use and you believe the error is caused by a problem with the product, take one of the following actions:

- If you have a Software Product Services Support Agreement, contact your Customer Support Center (CSC) by telephone or by using the electronic means provided with your support agreement (such as DSNlink). The CSC provides telephone support for high-level advisory and remedial assistance. When you initially contact the CSC, indicate the following:
  - The name and version number of the operating system you are using
  - The version number of the product you are using
  - The version number of INTERCHANGE software you are using
  - The version number of BASEstar Classic you are using
  - The hardware system you are using (such as a model number)
  - The Allen-Bradley PLCs you are communicating with
  - A brief description of the problem (one sentence if possible)
  - How critical the problem is
- If you have a Self-Maintenance Software Agreement, you can submit a Software Performance Report (SPR).
- If you do not have any type of software services support agreement and you purchased this product within the past year, you can submit an SPR if you think the problem is caused by a software error.

When you submit an SPR, take the following steps:

1. Describe as accurately as possible the circumstances and state of the system when the problem occurred. Include the description and version number of the product being used. Demonstrate the problem with specific examples.
2. Reduce the problem to as small a size as possible.
3. Remember to include listings of any command files, INCLUDE files, or relevant data files, and so forth.
4. Report only one problem per SPR. This will facilitate a faster response.
5. Mail the SPR package to Compaq.
