Error description

  • SQL Server wrapper uses the default isolation serializable when
    using federated two phase commit.
    
    Here is the reproducing scripts:
    db2 => set passthru <your_server>;
    
    db2 => select transaction_isolation_level from
    sys.dm_exec_sessions where host_name = '<your_federation_host>';
    
    transaction_isolation_level
    ---------------------------
                              2
    
      1 record(s) selected.
    
    db2 => set passthru reset;
    DB20000I  The SQL command completed successfully.
    
    db2 => alter server SQLSERVER options(set DB2_TWO_PHASE_COMMIT
    'N');
    DB20000I  The SQL command completed successfully.
    db2 =>
    db2 => set passthru <your_server>;
    DB20000I  The SQL command completed successfully.
    db2 => select transaction_isolation_level from
    sys.dm_exec_sessions where host_name = '<your_federation_host>';
    
    transaction_isolation_level
    ---------------------------
                              2
    
      1 record(s) selected.
    
    db2 => set passthru reset;
    DB20000I  The SQL command completed successfully.
    
    This APAR will support new behavior: set the remote
    corresponding  isolation according to DB2's isolation.
