Hi List,
I have a few questions on the RAC architecture in the 9i2 release:
1) Per the "Oracle 9i2 RAC Concepts" manual, the number of LMS processes
range from 0-9 (a total of ten processes). However some document
suggested that there are (# of CPUs)/4 LMS processes with a minimum of
two. Which is the correct statement?
2) Per the "Oracle 9i2 RAC Concepts" manual, the GCS and GES maintain
the GRD. What part of GRD is maintain by the GCS processes (LMS) and
what part by the GES (LMD) process ?
3) What process looks up blocks in the GRD
Any help will be appreciated
Thanks
Amir
