The total memory SAP ASE requires to start is the sum of all memory configuration parameters plus the size of the procedure cache plus the size of the buffer cache, where the size of the procedure cache and the size of the buffer cache are expressed in round numbers rather than in percentages.
The procedure cache size and buffer cache size do not depend on the total memory you configure. You can configure the procedure cache size and buffer cache size independently. Use sp_cacheconfig to obtain information such as the total size of each cache, the number of pools for each cache, the size of each pool, and so on.
1> sp_configure "total logical memory"
Parameter Name Default Memory Used Config Value Run Value Unit Type -------------- -------------- --- ----------- ------------ --------- -------------------- ---------- total logical memory 33792 127550 63775 63775 memory pages(2k) read-only
The value for the Memory Used column is represented in kilobytes, while the value for the Config Value column is represented in 2K pages.
The Config Value column indicates the total logical memory SAP ASE uses while it is running. The Run Value column shows the total logical memory being consumed by the current SAP ASE configuration. Your output differs when you run this command, because no two SAP ASEs are configured exactly the same.
