Checking the Hardware Requirements
CPU, Main Memory, Disk, and Swap Space
Check whether you have sufficient hardware resources such as CPU, main memory, disk space, and swap space. The minimum swap space is 20 GB.

Space Requirements for the File System
Make sure that there is enough temporary disk space available in the file system for the update. You need this free space for the SUM directory, the download directory, and directory DIR_TRANS. We recommend at least 40 GB free space for the SUM directory as well as for the download directory, and 20 GB for the directory DIR_TRANS.
As the space requirements depend on the product, see also the document with additional product-specific information for your update procedure to find information about the requirements. This document is referenced in the Master Guide or Upgrade Master Guide, respectively.
Space Requirements in the Database
Make sure that enough temporary and permanent free space is available in your database.
Release upgrade only: The Software Update Manager calculates the space requirements for the database. The free space required is in the range from 50 to 200 GB.
Enhancement package installation or SPS update: The Software Update Manager takes the status of your database into account and calculates the exact space requirements.
The difference between the maximum disk space requirements and the permanent disk space requirements is automatically available as free space in the database as soon as the update is complete.
