APAR status

  • Closed as program error.

Error description

  • When a table is enabled for compression but does not yet have a
    compression dictionary defined, the Load utility can attempt to
    automatically build the dictionary if enough data can be
    sampled; this is know as Automatic Dictionary Creation (ADC).
    When the Load INSERT option is used and the Load attempts to
    build a dictionary, the utility may hang indefinitely.
    
    If stacks are collected of the DB2 processes (db2pd -db <name>
    -stacks ALL), you will see an edu named "db2ltsc" with a stack
    similar to this:
    
         msgrcv
         sqlorqueInternal
         sqlorque2
         sqluuGetBuffer
         sqluutse
    
    and an edu named "db2lrid" (or "db2lfrm0" if cpu_parallelism is
    1) with a stack similar to this:
    
         msgrcv
         sqlorqueInternal
         sqlorque2
         sqlulGetBuff
         sqluMDCRPGetAndInitNewExtent
         sqluBuildDictionary
         sqluSampleRec
    

Local fix

  • Reorg the table the create the dictionary before running the
    load.
