Greetings,

My backup enterprise currently consists of a Solaris 9 Sun V240 master
and 3 Sun X4200 RHEL3 Linux Media Servers running NB51MP5.

I've been getting the following messages for backups and duplications
to storage units on my Linux media servers:

   "problems encountered during setup of shared memory (89)"

I use disk storage units and a mixed LTO2/LTO3 library.

I've attempted to setup my Linux media servers similar to my Solaris 9
master by using the same NUMBER/SIZE_DATA_BUFFERS files in
/usr/openv/netbackup/db/config.  But on my Solaris 9 master, I also
had /etc/system settings for msgsys, semsys, and shmsys values.

I haven't been able to find anything about needing similar
/etc/system tuning on Linux (I believe the /etc/system equivalents are set
via the /etc/sysctl.conf file).

I'm hoping someone can tell me if all of the /etc/system parameters can
be set with sysctl on Linux and if their names are the same.  Here are my
current Solaris /etc/system parameters:

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=512
set msgsys:msginfo_msgseg=8192

set semsys:seminfo_semmap=64
set semsys:seminfo_semmni=1024
set semsys:seminfo_semmns=1024
set semsys:seminfo_semmnu=1024
set semsys:seminfo_semmsl=300
set semsys:seminfo_semopm=32
set semsys:seminfo_semume=64

set shmsys:shminfo_shmmax=536870912
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=220
set shmsys:shminfo_shmseg=100

Any help is appreciated.
