IC75723: MAXIMUM SIZE OF TAPESIZE PARAMETER IS WRONG IN ADMINISTRATOR'S REFERENCE.

APAR status

• Closed as documentation error.

Error description

• TAPESIZE Configuration Parameter is described in Administrator's
  Reference
  as below.
  
  TAPESIZE Configuration Parameter
  
  onconfig.std value
      0
  units
      Kilobytes
  range of values
      0 through 2,097,151
  
  But when we define much more size like 10240000, that means 10
  GB,
  the instance is started successfully. And when we backup DBS
  larger
  than 10240000 KB by ontape, ontape displays the prompt message
  for
  the next mount and continue working after mounting a new media.
  It shows the description in Administrator's Reference is wrong.
  It should be corrected and we would like to know the exact
  maximum
  value. LTAPESIZE is same.

  * USERS AFFECTED:                                              *

  * PROBLEM DESCRIPTION:                                         *
  * For the LTAPESIZE  and TAPESIZE configuration parameters,    *
  * the documentation showed the range of values as 0 through    *
  * 2,097,151.                                                   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * When you enter a LTAPESIZE or TAPESIZE value, specify 0 or   *
  * any positive number.                                         *
  ****************************************************************
  

Problem conclusion

• The correct range of values for the TAPESIZE  and the LTAPESIZE
  configuration parameters is 0 or any positive number. The real
  value  is operating-system dependent.
  
  (TAPESIZE specifies the size of the device to which ontape backs
  up storage spaces. LTAPESIZE specifies the maximum tape size of
  the device to which the logical logs are backed up when you use
  ontape for backups.)
