Problem Determination Guide

Note:
The Natural trace facility for DL/I is available in all Natural for DL/I environments.

To activate the Natural trace facility for DL/I (Dynamic Trace Activation)

• Execute the command NDLTRACE in library SYSDDM as follows:

  NDLTRACE ON parm1 parm2 parm3 

  Permitted values for trace parameters are either CMD, SER, ROU (according to the specifications in the given error message) or ALL to trace all events of Natural for DL/I.

To activate the Natural trace facility for DL/I (Initial Trace Activation)

1. Code the TRACE parameter in the NDLPARM module according to the specifications in the given error message.

   Or:

   Specify TRACE=ALL to trace all events of Natural for DL/I.

2. Assemble the NDLPARM module.

3. Link-edit the load module that contains Natural for DL/I.

To create and display the Natural trace for DL/I

1. Start the Natural session with DSIZE=64 (or smaller).

   This is required because the trace data is written into the DSIZE buffer.

2. Activate the trace facility (see above) and specify the following commands:

   TEST DBLOG D	Start DBLOG for DL/I.
   ...	Reproduce your problem here.
   TEST DBLOG D	Display the data logged.

To obtain the printout, execute the Natural module NDLBLOCK in the library SYSDDM with the following parameters:

• block type (3 bytes alphanumeric) = NDB

• block name (8 bytes alphanumeric) = dbd-name

To obtain the printout, execute the Natural module NDLBLOCK in the library SYSDDM with the following parameters:

• block type (3 bytes alphanumeric) = NSB

• block name (8 bytes alphanumeric) = psb-name

To obtain the printout, execute the Natural module NDLBLOCK in the library SYSDDM with the following parameters:

• block type (3 bytes alphanumeric) = UDF

• block name (8 bytes alphanumeric) = db-id**file-number
  (that is, 3 digits for the database ID, a literal separator "**" and 3 digits for the file-number)
