Setting up parallel processes dramatically increase the performance of Upgrades and Updates in SAP systems.
This article intends to explain the parallelism import mechanisms and how it works in such procedures.
Here, "parallelism" means:
1) the import of more than one package or more than one object of a package at the same time by the transport tools (tp and R3trans);
2) the execution of more than one backgound jobs on the batch phases (both dialog and batch);
3) the execution of more than one SQL process on the database level;
4) the exection of more than one R3load processe on the EU_IMPORT phase (loading data from DVDs in release upgrades) and on the migration of data in DMO scenarios (data migration option);
5) the execution of more than one phase at same time, during the UPTIME portion of the upgrade.
The information is intended mostly to the upgrade SUM tool (Software Update Manager), but also covers SPAM/SAINT.
