PI99281: CM BATCH AND COMPARE DO NOT DETECT CHANGE IN SEQUENCE DATATYPE RESULTING IN SQLCODE = -846 / SQLCODEN846

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a user processes changes to a sequence that include
  precision (for example, from Decimal(9) to Decimal(5), CM Batch
  and Compare overlook this change, and generate only an ALTER
  statement (for the other changes), not a DROP/CREATE of the
  sequence.   When a package containing the sequence is executed,
  the result can be a SQLCODE = -846 / SQLCODEN846 error:
  DSNT408I SQLCODE = -846, ERROR: INVALID SPECIFICATION OF AN
  IDENTITY COLUMN OR SEQUENCE OBJECT SEQUENCE
  >sequence_name<.
  REASON CODE = 2
  DSNT418I SQLSTATE = 42815 SQLSTATE RETURN CODE

  ****************************************************************
  When processing changes for a sequence with a built-in
  datatype, CM Batch and Object Compare may not detect a
  change in precision. As a result only a only an ALTER
  statement (for the other changes), and not a DROP/CREATE
  of the sequence, may be generated. When the package
  containing the sequence is executed, the result may be
  SQLCODE=-846 / SQLCODEN846:
  
  DSNT408I SQLCODE = -846,
  ERROR: INVALID SPECIFICATION OF AN IDENTITY
  COLUMN OR SEQUENCE OBJECT SEQUENCE
  schema.sequencename
  REASON CODE = 2
  DSNT418I SQLSTATE = 42815 SQLSTATE RETURN CODE
