Hello,
We have the sap page file PAGFIL00, this file is located in /usr/sap/<SID>/DVEBMGS00/data/.
Also we have two physical page volumes in the system. We can browse them by command lsps and we see that these volumes are almost always filled less then quarter. But the sap page file size constantly increases.
1) What is the use of the sap page file?
I cannot understand when we should say about this sap page file and physical paging space at the operating system level.
2) What's the difference between these two paging areas?
3) Why the sap page file is located in /usr/sap instead of in paging space of operating system? What are paging volumes for???
4) And finally what the sap system located in its page file and what it is located on paging volumes?
Can anyone clear to me this matter?
Thank you very much!
