  New function to enhance processing of TSO logon procedures.
  

Problem conclusion

Temporary fix

Comments

• When logging on to TSO, if processing of the logon procedure
  fails due to data set contention, then new message MSGIEF864I
  will be issued to the TSO user's terminal to identify the data
  set(s) that are already in use:
    IEF864I DATA SET dsname ALREADY IN USE
  This new message will accompany the existing MSGIKJ56457I
  message that indicates a failure during logon processing.

    The following is a new message:
  
    IEF864I DATA SET dsname ALREADY IN USE
  
    Explanation: During processing of a TSO LOGON procedure, a
                 data set was not allocated because another job
                 or user has requested control of the data set.
                 In most cases, the other job or user has
                 allocated the data set with DISP=OLD or DISP=MOD.
                 If the system detects that more than one data
                 set could not be allocated, this message will be
                 issued for each data set.
                 This message is only issued to the terminal of
                 the TSO user attempting to logon.
                 In the message text:
                 dsname - The name of the data set that was not
                          available.  This data set name can be
                          an alias (alternate name).
  
    System Action: LOGON processing ends. The system also issues
                 one or more of the following messages:
                 - IKJ56457I
                 - IEF211I
                 - IEF861I
                 - IEF863I
  
    User response: Wait for the data set to become available and
                 retry the logon process.  If the error
                 continues, contact the operator or system
                 programmer.
  
    Operator response: Determine which address space, job, or
                 started task is using the data set by issuing
                 the following command:
                   D GRS,RES=(SYSDSN,dsname)
                 If applicable, wait for the data set to become
                 available, or contact the System Programmer.
  
    System programmer response: See Operator response.
                 Considering the output provided by the D GRS
                 command, take one of the following actions:
                 - Wait for the data set to be released.
                 - Contact the owner of the address space, job,
                   or started task that is holding the data set
                   to have the data set released.
                 - Cancel the address space, job, or started task
                   that is using the data set.
