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.

Note

If you did not make the ALIAS SAPTRANSHOST known, the default value is valid for DIR_TRANS (your central instance):

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

Procedure

Adjusting the general configuration:
1. Enter the ALIAS SAPTRANSHOST on the domain name server for the transport host you have chosen.
2. 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. The 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).
  
  Example transdir = \\$(SAPTRANSHOST)\sapmnt\trans\
Adjusting the SAP-specific configuration:
1. Provide each transport user who wants to access the central transport directory with write authorization for the transport directory and its subdirectories.
2. Parameter DIR_TRANS
  The 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, such as sapntchk and sappfpar.
  
  Do not set this parameter explicitly, since the default value, which points to \\$(SAPTRANSHOST)\sapmnt\trans, is usually correct.
  
  If you do not want to store the path under the share \sapmnt\trans within the transport directory, you can convert the parameter DIR_TRANS using the macro $(SAPTRANSHOST).
  
  Example DIR_TRANS = \\$(SAPTRANSHOST)\transport
  
  If you do not set the parameter DIR_TRANS in any profiles, the default value is activated.
  
  Note 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.
