[Orca-users] running problems ...

[Cockcroft, Adrian]

I'm sure I fixed this type of problem years ago in the iostat_class
code, but for some reason someone re-implemented the code in orcollator
itself and didn't make it robust enough. The problem occurs because the
operating system says it has a number of disks, and the code allocates
enough space for that many disks, then when more disks return iostat
records (including partitions) the code dies with this error.

 

I don't have the latest orca code running, but someone in the
development team should implement a simple fix.The code looks something
like this and uses a cool SE language feature that lets you realloc a
data structure to be bigger or smaller using the renew keyword.

 

If (subscript >= sizeof(RAW_disk)) renew RAW_DISK[sizeof(RAW_disk)+20];

 

That's from memory, but look at the network_class and iostat_class code
to see examples.

 

The workaround is to use se -DMAX_DISK=<a large number> orcallator.se
until it stops crashing. Starting at greater than 1024

hello again all,

i have (finally) installed orca on a bunch of machines - all
the same.  however on ONE of my boxen, the orcallator process
(started with 'start_orcallator') dies after running for a
while, and leaves the following message in /nohup.out.

Fatal: subscript: 1024 out of range for: RAW_disk[1024]: Near line 787

does anyone know what the heck's going on?

regards,

peter ryall.
