Finger pointing?

Shared memory and Semaphores are interprocess communication (IPCS).  The
parameters are set in the OS even though it is typically the application
that requires the setting.

Veritas (Symantec) would rightly say that it is up to Sun to say HOW to
set the parameters.  Sun would be right to say it is up to Veritas
(Symantec) to say WHAT values should be set.

Instead of asking Sun how to set the parameters for NetBackup ask them:

How do I set shared memory segments and related parameters?  How do I
set semaphores and related parameters?   Both of these should be
questions they should answer.   Once they do then you can probably use
the same values you've used before.

In other OS types (e.g. HP-UX) it's not "shminfo_shmmni" - it's just
"shmmni" so it may be they've made that change in Solaris 10 (haven't
worked with it so don't know).  That's why it's better to ask the above
questions than say "how do I set shminfo_shmmni?".

Subject: [Veritas-bu] NetBackup 5.0MP6 on Solaris10

I am looking at upgrading my netbackup servers from solaris 8 to solaris
10.  My existing config involves some /etc/system parms to accommodate
the SIZE_DATA_BUFFERS and NUMBER_DATA_BUFFERS:

** VERITAS NETBACKUP SPECIFIC PARAMETERS
**
* Grab sufficient amount of memory for NETBACKUP
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=65535
set shmsys:shminfo_shmseg=200
set shmsys:shminfo_shmmax=4294967295
*
* Allocate semaphores for NetBackup
set semsys:seminfo_semume=64
set semsys:seminfo_semmap=64
set semsys:seminfo_semopm=32
set semsys:seminfo_semmni=1024
set semsys:seminfo_semmns=1024
set semsys:seminfo_semmnu=1024
set semsys:seminfo_semmsl=300
*
* Increase the systems message queue resources to avoid bpsched hangs
set msgsys:msginfo_msgmap=512
set msgsys:msginfo_msgmax=8192
set msgsys:msginfo_msgmnb=65536
set msgsys:msginfo_msgmni=256
set msgsys:msginfo_msgssz=16
set msgsys:msginfo_msgtql=1024
set msgsys:msginfo_msgseg=8192
*
** End VERITAS NETBACKUP SPECIFIC PARAMETERS
*

My issue is that Solaris 10 does not support most of these settings in
/etc/system so I am wondering how I am going to config the new OS to
support the tape buffers . . . I have opened cases with both veritas and
sun and have received nothing useful, mostly finger pointing!  Has
anyone done this upgrade?  If so, how did you config the OS to support
the tape buffers?

Thanks!

Scott
