Announcing the Central Transport Host  

Use

You have set up a common transport directory for (almost) all of the SAP systems where you want to centrally manage your transports. You also want to simplify the maintenance of the transport directory by keeping the directory in a central location.

The advantage of a central transport host is that you have to maintain just one central entry when moving the transport directory to another host, and not the parameters of each system.

To do this, announce the name of the central transport host where your central transport directory is located in the Domain Name Server (DNS) for all Windows systems.

If you do not announce the ALIAS SAPTRANSHOST, the system applies the default value for DIR_TRANS (your central instance):

DIR_TRANS = \\$(SAPGLOBALHOST)\sapmnt\trans

Procedure

...

       1.      Adjusting the general configuration:

...

                            a.      Enter the ALIAS SAPTRANSHOST on the domain name server for the transport host you have chosen.

                            b.      Maintain the transport directory in the transport profile.

The transport control program tp works with its own profile and cannot access the default SAP profiles. Parameter transdir, which is located in this profile, contains the path of the transport directory. You need to set this parameter. For a central transport directory, define the parameter using the macro $(SAPTRANSHOST).

transdir =  \\$(SAPTRANSHOST)\sapmnt\trans\

       2.      Adjusting the SAP-specific configuration:

...

                            a.      Provide each transport user who wants to access the central transport directory with write authorization for the transport directory and its subdirectories.

                            b.      Parameter DIR_TRANS

Parameter DIR_TRANS contains the path of the transport directory and is maintained in the instance-specific profile (possibly in default default.pfl). This parameter is evaluated by all programs that can evaluate profiles. These are the SAP kernel and various additional programs, like sapntchk and sappfpar.

Do not set this parameter explicitly, since the default value that points to \\$(SAPTRANSHOST)\sapmnt\trans\ is normally correct.

If you do not want to store the path under the share \sapmnt\trans in the transport directory, you can convert parameter DIR_TRANS using macro $(SAPTRANSHOST).

DIR_TRANS =  \\$(SAPTRANSHOST)\transport

If you do not set parameter DIR_TRANS in any profiles, the default value is activated.

 

If a system that a central transport host has been configured for is not supposed to transport to a central transport directory, you need to override the default values.
