Error description

  • Rational Developer for System z - RDz - V9.1
    
    If two commands  are executed in the same TSO gateway session,
    one command might pick up the result of the other command and
    send the result to RDz client.
    
    Recreation steps:
    
    Just after connecting to a remote system, select a dataset
    member in a subproject and quickly ask for a Remote Syntax Check
    (Ctrl+Alt+R). You might get the following error:
    
    Performing remote syntax check for '<filename>' has encountered
    a problem
    
    followed by:
    !MESSAGE Sequential Data set allocation error: SYSDSNAME....
    <PDS name>
    SYSVOLUME.... VOL116
    SYSUNIT...... 3390
    SYSDSORG..... PO
    SYSRECFM..... FB
    SYSLRECL..... 80
    SYSBLKSIZE... 27920
    SYSKEYLEN.... 0
    SYSALLOC..... 78
    ...
    
    In this case, the 'FEKFERRF' command (used to allocate SEQ file
    for error feedback) returns the results of 'listds' command
    (properties of the dataset).
    

Local fix

  • As a workaround, uncomment the following line in rsed.envvars
    in order to have only one thread:
    
    _RSE_JAVAOPTS="$_RSE_JAVAOPTS
    -DDSTORE_USE_THREADED_MINERS=false"

    ****************************************************************
    01.If FEKFERRF & listds commands are executed in the same TSO
       gateway session almost at the same time, one command might
       pick up the result of the other command and send the result
       to RDz client.
    

Problem conclusion

  • 01.Now, both commands are not executed on the TSO gateway
       session.
