swinstall problem

[Mark Fazakerley]

Hi,

I have a L1000 (HPUX 11i) with 512Mb memory. I'm attempting to install a patch via the swinstall utility and get the following message :

%Internal DCE Threads problem (version CMA BL10+), terminating execution.
% Reason: cma__io_available: unexpected select error
% See 'cma_dump.log' for state information.
ABORT instruction (core dumped)

on selecting the patch depot to install. The patch isn't the problem as I've tried a number of patches.Has anyone seen this before?

I enclose the cma dump log file.

Any advice gratefully received.

Mark

Have you set the appropriate DCE kernel parameter limits as per the DCE Release notes ?

maxfiles and maxfiles_lim need to be set sufficiently high to stop DCE core dumping. The Relnotes recommend minimum of 256 but Ive seen suggestions a min of 2048 for each.

i think this is a known issue and my guess is your l-class has more than 1 cpu (safe bet i know) also I suspect any application using dce threads will be effected ...so swlist probably doesn't work either :

please install PHKL_25869 then get back to us ....

Thanks for the last two messages. In answer to the first:

Currently, max_files is set to 60, and max_files_lim is set to 1024. I'll up the max files and see what gives. I can't up max_files_lim as sam tells me the number is out of range for any value over 1024.

I'll try the patch now...

Hi,

stop all the dce process (like /opt/dce/sbin/rpcd) and start installing again. usually DCE configuration causes some problem in swinstall,swremove, swlist.
and also unset the parameter RPC_SUPPORTED_PROTSEQS which will be set to RPC_SUPPORTED_PROTSEQS=ncadg_ip_udp when the DCE is configured.
(#unset RPC_SUPPORTED_PROTSEQS).
HP is developing a patch to over come this problem

The maximum value for maxfiles and maxfiles_lim is 60000.
you cannot bump the value as it is dependent on the nfile and ninode values

Thanks

I've upped the maxfiles value and applied the patch as advised - so far so good. No unexpected select error. I'll try the remaining patches, but suspect that all will be okay now.

Thanks to all who replied.
