Examples of Using the Audit Trail Specifications

The following examples illustrate valid DASDL syntax for the audit trail specification.

Example 1

In this example, an audit trail is requested by using the AUDIT option, and the restart data set R is declared. As no explicit audit trail information is supplied, default values are used. 

OPTIONS (AUDIT);

R RESTART DATA SET
 (
  X ALPHA(100);
 );

D DATA SET
 (
  A ALPHA(10);
 );

Example 2

This example includes specific settings for the following audit trail features:

  • A maximum of 150 areas are assigned to the audit file.

  • Each area length is 2000 blocks.

  • A checksum is used to detect I/O errors.

  • The primary audit file is written to the AUDPACK pack.

  • The audit file is divided in 4 sections.

  • The end-of-file pointer is updated every 50 blocks.

OPTIONS (AUDIT);

AUDIT TRAIL
 (
  AREAS      = 150,
  BUFFERS    = AUTOMATIC,
  AREASIZE   = 2000 BLOCKS,
  CHECKSUM   = TRUE,
  PACK       = AUDPACK,
SECTIONS = 4
,
  UPDATE EOF = 50 BLOCKS
 );

R RESTART DATA SET
 (
  X ALPHA(100);
 );

D DATA SET
 (
  A ALPHA(10);
 );

Example 3

This example includes specific settings for the following audit trail features:

  • A maximum of 68 areas are assigned to the audit file.

  • Each area length is 100 blocks.

  • The block size is set 900 words.

  • A checksum is used to detect I/O errors.

  • The primary audit file is written to the AUDPACK pack.

  • The primary audit file is written to the tape when the AUDPACK pack is full.

  • The primary audit file is copied twice to the tape and then removed from the AUDPACK pack.

  • The secondary audit file is written to the tape.

  • The end-of-file pointer is updated every 50 blocks.

OPTIONS (AUDIT);

AUDIT TRAIL
 (
  AREAS      = 68,
  AREASIZE   = 100 BLOCKS,
  BLOCKSIZE  = 900 WORDS,
  CHECKSUM   = TRUE,
  PACK       = AUDPACK
                 ALTERNATE IS TAPE,
                 COPY TO TAPE 2 TIMES AND REMOVE,
  DUPLICATED ON TAPE
                 DESIGNATED "AUD001" TO "AUD999",
                 VERIFY,
  UPDATE EOF = 50 BLOCKS
 );

R RESTART DATA SET
 (
  X ALPHA(100);
 );

D DATA SET
 (
  A ALPHA(10);
 );

Example 4

In this example, an audit trail is requested by using the AUDIT option, and the restart data set R is declared. The audit file is written to a tape from the scratch pool POOL2. 

OPTIONS (AUDIT);

AUDIT TRAIL
  (
   KIND = TAPE
   SCRATCHPOOL = POOL2
  );

R RESTART DATA SET
 (
  X ALPHA(100);
 );

D DATA SET
 (
  A ALPHA(10);
 );
