  SUMMARY OF ADMIN_INFO_SQL EVENTS:
  
  The ADMIN_INFO_SQL stored procedure captures statistics
  about a DB2 subsystem, its objects, and applications and
  returns the results in a data set or as a result set.
  This information can help IBM Software Support recreate
  and troubleshoot problems, like a poorly performing SQL query.
  
  ADMIN_INFO_SQL was sometimes not producing the correct output
  when creating the DDL and STATS output files that are used
  by DB2 service to re-create a problem related to query
  processing.  Here are a list of reported issues:
  
  - ADMIN_INFO_SQL syntax problem with newline causing problems
    with Java result sets.
  
  - ADMIN_INFO_SQL not closing the cursors when calling
    ADMIN_COMMAND_DB2 stored procedure.
  
  - ADMIN_INFO_SQL formatted STATS_FORMAT in SYSKEYTARGETS
    incorrectly.
  
  - Reduced code and data segment size for ADMIN_INFO_SQL.
  
  - Several array sizes were incorrect and could cause an
    overlay.
  
  - Wrapping EXPLAIN information when using job DSNTEJ6I
    to call DSNADMSB. Added DCB=(RECFM=VB,LRECL=4096) to
    SYSPRINT.
  
  ADMIN_INFO_SQL had several new features added:
  
  - Get foreign key dependencies.
  
  - Index probing and real-time statistics (RTS) collection.
  
  - Production modeling.
  
  - DSN_QUERYINFO_TABLE collection.
  
  - Now gets MEPL information.
