I just finished a test install on Oracle Enterprise Linux 5; I wanted to check how well ASM 11g does work with a 10g database.
I did install Linux 2.6.18-8.el5, Oracle 126.96.36.199, ASMLib 2.0.3-1.el5 and Oracle 10.2.0.1 + patch set 10.2.0.3
All the installs completed smoothly on my laptop virtual machine. Note that you can also download Oracle VM from November 14. You can see here the
Oracle Unveils Oracle® VM announcement.
At last my configuration includes 11g ASM + 11g database + 10g database, all living together in harmony.
You can download Oracle Enterprise Linux 5, 11g and 10g from Oracle Edelivery page.
