IT16678: MQ Explorer has incorrect range in warning for queue manager extended property 'errorLogSize'

APAR status

• Closed as program error.

Error description

• When using the IBM MQ Explorer and opening the "Extended" queue
  manager properties page of a local queue manager that does not
  have the ErrorLogSize property configured in its qm.ini file,
  the value of field "Error log size" displayed by the MQ Explorer
  contains the default value of 262144.  Removing the 262144
  value, a yellow warning icon appears beside the empty field.
  Moving the cursor upon the warning icon, a tooltip appears with
  the text:
  
    "Input out of range (0 - 2147483647)"
  
  The default value 262144 and value range (0 - 2147483647) are
  not correct.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of the:
  
    - IBM MQ V8 Explorer
    - IBM MQ V9 Explorer
  
  who are modifying a local queue manager's "Error log size"
  property in the "Extended" pane of the queue manager Properties
  window and that local queue manager did not contain an
  ErrorLogSize entry in its qm.ini file.
  
  
  Platforms affected:
  Windows, Linux on x86-64, Linux on x86
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  From WebSphere MQ V7.1, the default size of the queue manager's
  error log files increased from 256KB to 2MB, however the IBM MQ
  Explorer was not updated to reflect the change in the default
  size for queue manager's at this version or higher.  The MQ
  Explorer displayed the default value as 262144 rather than
  2097152.
  
  Furthermore, when the user did not enter a value for the queue
  manager's "Error log size" property in the "Extended" pane of
  the queue manager "Properties" window, the small warning icon
  that appeared to the left of the box showed an incorrect range
  of values for this property when the cursor was placed over the
  icon.  The range was shown as accepting values from 0 to
  2147483647 but the correct range is 32768 to 2147483648, as per
  the documentation in the following Knowledge Center page:
  
  http://www.ibm.com/support/knowledgecenter/SSFKSJ_9.0.0/com.ibm.
  mq.con.doc/q019020_.htm
  
  Note that the maximum value in the tool-tip was 1 less than the
  maximum defined in the Knowledge Center page, "Queue manager
  error logs".  This was due to a limitation with the Eclipse
  widget used to implement the GUI value "spinner" object
  representing the queue manager's error log size property as the
  maximum size permitted was the maximum of a Java int, primitive
  which is 2147483647.
  

Problem conclusion

• The IBM MQ Explorer has been updated such that the correct
  default size for the queue manager error logs is shown in the
  "Extended" pane of the queue manager "Properties" window.
  
  A custom Eclipse widget has also been defined for the queue
  manager "Error log size" property that will permit the full
  range of valid values for the size of the queue manager error
  logs, which is 32768 to 2147483648.  This custom widget no
  longer displays a tool-tip when the value in the text field is
  invalid.  However, when a different queue manager extended
  property is selected, or the Apply or "OK" button is clicked,
  Explorer will change the value in the field to be either:
  
    - the maximum permitted value if the value that was entered is
  greater than 2147483648
  
  or
  
    - the minimum permitted value if the value that was entered is
  less than 32768
