The purpose of this page is to clarify the parameter settings of DIR_TRANS and DIR_EPS_ROOT.
Transport enables you to transfer the changes from the development system to the other successive systems along the transport route.
Transporting or export/import of the transport needs a directory to store and access data, cofiles, logs, variables, etc., in a location known as transport directory of DIR_TRANS. Similarly DIR_EPS_ROOT is the directory where transaction SPAM/SAINT finds the files containing support packages to be implemented. The parameter configuration of these directories needs careful evaluation to make best use of the available resources with regard to the infrastructure. These two directories and the necessary sub-directories are created during installation.
As part of TMS , configuration of these two parameter settings will be done
a) DIR_TRANS: Mmake the necessary settings for a system, so that it can be provided with transports, which transport directory is to be used.
This could be for example as follows :
DIR_TRANS is to be changed in the R/3 default profile.If the central instance is running on UNIX and there is an application server running on Windows, DIR_TRANS needs to be set in the instance profile of the Windows-application server.
b) DIR_EPS_ROOT is the directory where transaction SPAM finds the files containing support packages. It is set to: DIR_TRANS/EPS or DIR_TRANS\EPS respectively
DIR_EPS_ROOT is to be changed in the R/3 default profile.Just as DIR_TRANS, DIR_EPS_ROOT has to be set in the instance profile of an Windows-application server, if the central instance is running on Unix.
This page describes what parameter settings need to be done for the transport directory if several SAP systems exist on the same host.Parameter settings of transport directory if several SAP systems exist on different host.
Parameter settings of transport directory if several SAP systems exist on the same host.
Rename the transport Directory and use a unique name on the host for the new transport directory if several SAP systems exist on the host.
For example, the SAP ID could be used: /usr/sap/trans_<SID>. Adapt the instance profile parameters DIR_TRANS to /usr/sap/trans_<SID> and DIR_EPS_ROOT to /usr/sap/trans_<SID>/EPS
and restart the system.
Rename the transport directory paths(DIR_TRANS and DIR_EPS_ROOT) of <SID> in transaction STMS to the new name. Change the parameters accordingly for the corresponding systems(<SID>,<SID1>,<SID2>..).
Parameter settings of transport directory if several SAP systems exist on different hosts.
- Two systems <SID> and <SID1> are residing in different hosts but are using the same transport directory(<TRANSDIR>=/usr/sap/trans/).
- Parallel upgrades have to performed and without proper parameter settings it may result in the following error.
Error in CAR.ECO for <SID1>,while <SID> is also using the shared transport directory. This indicates the upgrade tool tries to use the DIR_EPS_ROOT for both <SID> and <SID1> and results in following error
EXECUTING .../SUM/SAPCAR -R .../trans -xvf
processing archive .../KIPYJ79.CAR...
can't change date of file EPS/in/CSN0120061532_0024092.ATT
To make the upgrade tools to use the correct electronic parcel service inbox, adapt the corresponding instance profile parameter of <SID1> as DIR_EPS_ROOT to <TRANSDIR>/EPS_<SID1>/EPS and restart the system. Also rename the DIR_EPS_ROOT path of <SID1> in transaction STMS to the new name. Whereas system <SID> continues to use <TRANSDIR>/EPS .i.e,
<TRANSDIR>/EPS ----> for the upgrade of the system <SID>
<TRANSDIR>/EPS_<SID1>/EPS ----> for the upgrade of the system <SID1>
