Maintaining the Transport Directory

For tp, the transport directory must meet the following requirements (depending on the operating system):

UNIX

A transport network must contain a single physical transport directory that can be accessed from each host using the same path.

In UNIX systems, this directory can be a soft link, pointing to the correct transport directory or mount point.

You need to store the chosen path in two parameters:

• Parameter transdir for the transport control program in the Transport Profile
• Parameter DIR_TRANS for the SAP System in the instance profile

The default value for the transport directory is /usr/sap/trans in UNIX.

Microsoft Windows

Transport groups comprised of Windows systems, or of Windows and UNIX systems are supported.

For more information on creating a heterogeneous transport group, see Transport Control under Windows.

SAP allows you to name a central transport host on the Domain Name Server that is valid for all Windows systems.

For more information on specifying a central transport host on the Domain Name Server, see Specifying Central Transport Host.

Each transport group must have a single physical transport directory that can be accessed by all machines.

This directory is described by the parameters:

• transdir (transport profile)
• DIR_TRANS (instance-specific profile)

  If you have entered a transport host on the domain name server, the default location for the directory is \\$(SAPTRANSHOST)\sapmnt\trans.

  If not, it is located at \\$(SAPGLOBALHOST)\sapmnt\trans.

The transport directory is described by the following parameters:

• SAPTRANSHOST

  Name of the host configured as the central transport host on the Domain Name Server

• SAPGLOBALHOST

  Name of the host on which the central system is installed

• sapmnt

  Global share that points to the \usr\sap file tree on the central instance

  Note

  Note the different naming conventions used for parameters transdir and DIR_TRANS:

  The path specified for parameter DIR_TRANSdoes not end with a "\", whereas the path entered for parameter transdir does:

DIR_TRANS = T:

transdir = T:\

 

IBM IBM i

A transport network must contain a single physical transport directory that can be accessed from each host using the same path.

In IBM i systems, this directory can be a soft link, pointing to the correct transport directory or mount point.

You need to store the chosen path in two parameters:

• Parameter transdir for the transport control program in the Transport Profile
• Parameter DIR_TRANS for the SAP System in the instance profile

  The default value for the transport directory is /usr/sap/trans in IBM i.
