OA43509: IEATDUMP MAY PRODUCE A PARTIAL TRANSACTION DUMP IF THE DUMPED ADDRESS SPACE HAS ALLOCATED A LARGE AMOUNT OF >2G STORAGE.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The range table used by IEATDUMP to store information regarding
  storage above the 2G bar, may become full if a large amount
  of >2G storage is to be dumped.
  This will result in the transaction dump being partial.
  
  Verification Steps:
  
  1. Dump is requested via IEATDUMP.
  2. The following message is shown in SYSLOG:
     IEA827I PARTIAL TRANSACTION DUMP WRITTEN TO 00001 DATASETS
  3. Return code 4 and Reason code 7 from IEATDUMP request.
  
  If the IEATDUMP request was issued under the JVM, the following
  messages may also be seen:
  
  JVMDMP025I  IEATDUMP failed RC=0x00000004 RSN=0x00000007
              DSN=dsname
  JVMDUMP012E Error in System dump: dsname

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IEATDUMP dumps                  *
  ****************************************************************
  * PROBLEM DESCRIPTION: MSGIEA827I PARTIAL IEATDUMP RC04 RSN07  *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The problem may occur for applications that are using many
  areas of 64-bit storage that are not contiguous. IEATDUMP must
  track these areas using tables that can only handle a finite
  number of ranges. When the table is filled up, processing
  stops. MSGIEA827I PARTIAL TRANSACTION DUMP WRITTEN is issued,
  and RC04 RSN07 is returned to the application that invoked
  IEATDUMP. This indicates that the dump only contains some of
  the data that was requested.
  

Problem conclusion

• IEAVTDMP was changed to increase the capacity of the range table
  to support more ranges. Conditionally requesting 80K, but will
  settle for the existing 32K (of LSQA) if only that is available.
