I run a sapdb on a RedHat 8.0 System. This System has 1 GB Main Memory, and 2 Gb Swap Partition.
The SAPDB has 4 GB Data (2 GB full) and 1 GB Log (50 MB full) .
The ChacheSize of the sapdb amounts 800.000 Pages !
The Data Hit Chache Rate lies at 97 %.
Now the problem :
The sapdb writes the Main Memory till it's full. After that it writes the Swap Partition, also untill it's full. The problem is, that after a sapdb Process (e.g. select) is done, the memory is still full. So it wouldn't be cleared by sapdb after a selection. And so, after time and time, the memory and swap partition is full of sapdb data, and the system doesn't work anymore (overflow).
What might be the reason for that ? The high ChacheSize ?
Best regards, Danny
