APP Server ST02 Tamp> setups/Buffers R/3 memory configuration Monitor (also known as the function setups & tune buffers ). its Tune summary reports load on R/3 buffers and other memory areas. buffer hit ratio = buffer object reads/logical requests. poor buffer Quality = saved database cballs/(Database cballs + saved database cballs)

R/3 tablespaces

Type Tablespace Contains tables Size Activity
Transaction tablespaces PSAPBtabD Holds sap transaction tables holding order headers, line items, purchase orders, etc. Large Highest
PSAPStabD Master Data and transparent tables with high Write activity such as item master, customer data, pricing, etc. Largest Highest
PSAPUser1D Defined to hold user customization (customer tables) not defined with the SAP software. Depends Depends
PSAPVb0101D & PSAPVb0102D - Large Very high
Basis tablespaces PSAPDictD ABAP Data Dictionary (usually cached in memory due to frequent reference ). Small Low
PSAPLoadD ABAP report loads and screens. - High
PSAPSourceID ABAP report source code and screens. - Medium
PSAPProtD A heavy-use tablespace. Spool, customer, log files, reports and printouts generated by any SAP process. - Highest
System tablespaces PSAPPoolD System pool tables that sap considers too small to be in their own tables. These are generally buffered in memory, so they're accessed at sap startup time but not heavily after that. Small Low
PSAPCluD Cluster tables used by SAP as subtables containing long raw datatypes, which must be reorganized using Oracle's slower export/import utilities instead of Oracle's faster create table as SELECT command. Large Medium
PSAPDocuD Contains codument tables, including sapscript and sapfind tables. Small Low
