Re: error messages of "uerf -R"

Did you check other log files - syslogs, binary logs, /var/adm/messages etc?

From this output, it looks like a Memory channel problem.

Re: error messages of "uerf -R"

Hi,

did Oracle stop or the machine?
Use decevent or webes for better error details.
Have you looked for the alertlog?

greetings,

Re: error messages of "uerf -R"


panic (cpu 0):_rm_failover_if_necessary, both rails_bad

Above sentence in the output says it all:

It was a panic and it happened because both memory channels had a problem. Very bad because you counted on them for redundancy.

Do you have memory channel HUBs ?
Any optical fiber MC extensions ?

And as Michael said, uerf is obsolete, it supports only pre-AS4100 CPU's and devices.
For more recent configs, install WEBES from layered product CD and use command:

wesea n trans out /tmp/errlog.txt full

Rgds,
