Error description

• Users can configure event subscription on an item type with
  AddItem event and use a string type attribute. When an AddItem
  CommonBaseEvent is generated by the event monitor, it reports an
  attribute length of zero (ATTRLEN=0) while it also reports its
  attribute value (ATTRVAL) as not being an empty string.  For
  example, CommonBaseEvent can display something like the
  following:
  
  ICMEMSTART;ETYPE=ITEM;EACTION=CREATE;ECODE=301;
  ...
  ATTRNAME=ABC;ATTRLEN=0;ATTRTYPE=448;ATTRVAL=XYZ;
  ...
  
  This zero length might cause an error in a custom event handler
  that is designed to handle General Integration event
  subscriptions.  Such a handler might rely on the correct ATTRLEN
  value before it reads the ATTRVAL field.
  
  This problem occurs only on a 64-bit library server running on
  UNIX platforms (except x86 Linux.) 32-bit library servers on
  UNIX platforms do not
  have this problem.

  * 843                                                          *

  * PROBLEM DESCRIPTION:                                         *
  * After the user configured event subscription on an item type *
  * with AddItem event type and a string type attribute (such as *
  * variable character, date, timestamp data type), an AddItem   *
  * CommonBaseEvent might be generated by the event monitor      *
  * whenever an item is created in that item type.               *
  * The CommonBaseEvent has fields to indicate attribute length, *
  * type and value of the subscribed attribute. However, if the  *
  * subscribed attribute is of string type, the attribute length *
  * is reported as zero regardless of whether the attribute      *
  * value is empty or not.                                       *
  *  Here is what the CommonBaseEvent might look like:           *
  * ICMEMSTART;ETYPE=ITEM;EACTION=CREATE;ECODE=301; ...          *
  * ATTRNAME=ABC;ATTRLEN=0;ATTRTYPE=448;ATTRVAL=XYZ; ...         *
  *                                                              *
  * This will cause an error in the custom event handler for     *
  * General Integration event subscription. Such a handler might *
  * rely on the correct value of ATTRLEN to further read the     *
  * ATTRVAL field.                                               *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * N/A                                                          *

Problem conclusion

• A wrong variable data type was used to store the attribute
  length.  It was changed to use correct data type.
