Informix database virtualization
Alain Deschamps asked about pitfalls and best practices for running Informix on VMware or other virtualization. Art S. Kagel reported IDS ran well on Solaris partitioned machines. Martin Fuerderer saw it on Xen paravirtualized Linux with about native performance, though without UDRs or datablades and with little testing. Paul Watson reported several customers on Linux-based VMware with failover and no issues. No problems were reported.

Has anyone experience with running Informix on vmware or other virtualization solutions ? What pitfalls are there to be aware of when running your database on a virtualized infrastructure ? Are there any best practices ? Krgds Alain Deschamps

Hi, I saw one running on XEN Linux. The VM was running in paravirtualization mode.The usual OS-dependent functionality was OK: no age, processor affinity, raw devices, direct I/O. It did not have UDRs and datablades. Performance was about the same as running IDS in the domain0 (i.e. native on Linux without VM). Though no extensive performance testing was done at that time. So it looked quite usable.

Got a couple of versions running off a USB stick, the only issue there was finding a Linux image with a very small footprint.
