File Structure for tp

On all operating systems, tp requires a special file structure for transport data, logs, temporary data, and transport control data. The file structure is operating system-dependent, but SAP has tried to keep these differences as small as possible.

tp needs a transport directory called /usr/sap/trans on UNIX. You can also use any other directory in the file system, but it must exist on every machine in your network where an SAP instance is running (UNIX: mounted, Windows: share). If this is not the case, you cannot install a transport system that runs automatically.

You can find more information on how to address and rename the transport directory in the section Preparing the File Systems.

The transport directory must have the following subdirectories:

• bin:

  Contains the global transport parameter file.

• data

  Contains the transport data.

• log

  Contains transport logs, trace files, and statistics.

• buffer

  Contains control information on which transports are to be imported into which SAP systems and the order of the imports.

• cofiles

  Contains information on change requests (different steps of a change request and their exit codes).

• sapnames

  Contains information for SAP users (the state of each change request).

• tmp

  Contains temporary files (logs, semaphores on files).

• actlog

  Contains action logs for all tasks and requests. These files are only changed by the SAP system.

• olddata

  Contains "old" files from other directories that are saved here using the clearold command before being deleted by a later execution of this command
