SAP Bugger: SAP Transport Basics : 1

Logical Sequence of Transport:

DEV -->QAS -->PRD

Technical Sequence:

Dev -->shared /usr/sap/trans/ -->QAS--->shared usr/sap/trans-->PRD

One successful transport is made up of 1 export & 2 import.

Transport Domain controller:

It means out of three system one system acts as central system for all Transport related activities.

Depending on 2 conditions TDC is assigned:

/usr/sap/trans of TDC is shared by other systems.

Suppose PRD is my TDC (highly available & secured). then usr/sap/trans of PRD shared by DEV & QAS.

Request created in DEV then how DEV knows to create files on PRD os /usr/sap/trans ?

“IP TDC <hostname> SAPTRANSHOST” stored in /etc/host

Before installation, we have to maintain this entry in all the hosts.

Transport Domain:

If all the systems controlled by TDC,then those systems are set to be in one transport domain.

One can have ‘n’ no of systems in one domain controlled by TDC.

No. of TDC= No. of common Transport Directory

System can have 2 TDC depends on frequency of Transport between one landscape to other landscape.

Transport Group:

‘N’ no of systems sharing one common transport Directory are set to be in one Transport Group.

It is possible to have 2 Transport group in one domain.

e.g. DEV & QAS sharing one trans dir whereas PRD is having separate trans directory.

Transport can happen between:
