Info

OSI/File Services filestore owners can define the accessibility to their filestores, limiting it: � Only to themselves, in which case it is a private filestore. � To other local users, in which case it is a public filestore. � To users on a remote system, in which case it is an open filestore. Users can also password-protect their filestores. For each local OSI/File Services user, the privileged user defines the user capability in the local system, indicating whether users can access: � Their own filestores � Other local filestores � Their own filestores and other local filestores. The filestore accessibility and user capability is set when a user is defined to OSI/File Services. The OSI server can only check that OSI/File Services-user ABC has allowed OSI/File Services-user DEF to transfer ABC’s files, if the user ID in OSI/File Services is the same as the TSO user ID. This is only possible for the interactive interface, because for the batch and API interfaces the job name is used instead of the user ID. For more information about OSI/File Services, refer to the OSI/File Services System/370 User’s Guide. 184 NetView FTP V2 MVS Installation, Operation, and Administration
Appendix B. Transfer Error Recovery Error Recovery for SNA Transfers The transfer error recovery in NetView FTP V2.2.1 MVS for SNA servers is based on its checkpoint facility. Checkpoint Facility Note: The checkpoint facility is not available for OSI/File Services. NetView FTP V2.2.1 MVS offers a checkpoint facility to recover from interrupts during a file transfer. You can recover from the following types of errors without transferring the complete data set again: � Telecommunication-line interruptions � Abnormal termination of the remote or local system (system malfunction) � Operator termination of the remote or local FTP. The checkpoint data set is used to store this recovery information, which is called a checkpoint record. Each checkpoint record is related to one file transfer. The checkpoint record is always written by the receiving server. Using the recovery information that NetView FTP V2.2.1 MVS has stored when the error occurred, it can resume the interrupted file transfer from the last recorded checkpoint. Sharing the Checkpoint Data Set A checkpoint data set is opened and accessed by a server. All servers at one NetView FTP V2.2.1 MVS installation can share the same checkpoint data set. This allows NetView FTP V2.2.1 MVS to restart a file transfer on one server that was interrupted while it was being processed on another server. You can also define a checkpoint data set for each server in your installation. If you do this, however, an interrupted file transfer can be restarted from checkpoint on the same server only. The request originator of a file-transfer request must ensure this by specifying that the request can be processed only by one specific server. You must define the checkpoint data set before you can start any server. The Checkpoint Record Depending on the NetView FTP level of the requesting transfer program, a checkpoint record consists of the following information: NetView FTP V2.2 MVS, NetView FTP for Workstations � Network ID of the requesting NetView FTP � LU name of the requesting server � ID of the request queue � Request number � Name of the sending data set � Name of the receiving data set � Name of the sending transfer program © Copyright IBM Corp. 1988, 1994 185
