diagnostics tool to check memory

[Houston Kemper]

Hello forum,

Is anyone aware of a diagnostics tool/utility that can be run to check memory?

Thanks

[Cheryl Griffin]

It depends on how you want to check memory. What information are you wanting to see?

There's Glance (available by trial) and then GlancePlus.

# dmesg
(there is a physical memory section)

# swapinfo -tam

Hello,

Use glance or GUI version gpm
Top will also show you
swpainfo will give you information on swap memory

STM is the usual tool for this .. I like "cstm" (the ascii version). Typically ..
# /usr/sbin/cstm
.. in CSTM prompt you would ..
cstm> map
cstm> sel dev
cstm> exc
cstm> map
=======> Look at the status of the "exc" (exerciser) to make sure it has completed before you proceed. It'll say 100% when done.
cstm> eal
cstm> efl
cstm> einf

The best thing for you to do is in cstm mode enter "he" to list the tools/commands available.

Sorry for my somewhat vague question. I guess what I'm looking for is a tool that can check memory integrity. Our DBA team had an Oracle instance crash and Oracle is reccommending us to run a diagnostics on the memory. I'm sure I can get a CE to come out and run a physical check on the memory, but I'm wondering if there is a tool that can thrash the memory. Kind of like a 'dd if=/dev/dsk/xxxxxx of=/dev/null' for memory.

Thanks

Memory diagnostics are run during the boot process - you could re-boot to check your memory.

Houston, this is the space shuttle, tell your DBA that if he/she spews out any more hot air, they'll be able to float their ideas to Mars.

Tell them you are waiting for HP to release the left handed mouse software for Glance.

.. you would want to run the "exerciser" on the memory then .. (see my suggestion)..
My comment .. if you don't see any error in ..
# /usr/sbin/cstm
.. in CSTM prompt you would ..
cstm> map
cstm> sel dev
cstm> info
cstm> infolog

.. then don't bother to run "exc" because any error condition on the memory should be flagged in "infolog" already.

If you are having Online Diagnostics installed, you can run stm or xstm. You can check the logs over there that if there was any failure or not.

Here is a program written in C for this. It checks memory and swap. It has been passed around by other people. (Thanks to whomever wrote it.)
