Summary :
SAP Note clarifies the settings for R/3 Memory Management to optimize system performance across various system releases, including new and upgraded R/3 systems post-Release 4.0. It documents detailed configuration advisories, especially after upgrades, which may influence R/3 system response times. Users are guided on initial settings and subsequent adjustments based on actual system needs. Not applicable to IBM iSeries, this note integrates related recommendations across multiple platforms, such as SINIX, specific memory recommendations for HP-UX, etc., encouraging the use of TCC Services prior to and following system updates to avoid performance issues.
