Omniback v3.5 - Shared Memory Problem

Alex Ring — Thu, 12 Apr 2001 13:51:43 GMT

Hi Guys

Im trying to test an eval copy of Omniback v3.5. Heres a desc of my setup.

Cell Server runs on Win2k SP1 Machine.

I have a Sun StorEdge L20 Tape Library connected to a Sun E420R running Solaris 2.7. The E420R has the client s/w and agents (DA & MA) installed. Eveything seems to be running and talking to each other fine.

I have configured the Backup device/drives & media, and have tried to run a very small test backup. Unfortunately, i get the following errors reported ;

Any ideas ??

Looks like a kernel problem. You might have to rebuild the kernel and increase the shared memory allocation variable. In HP-UX, I think it is shmmax. This should help, but I'm not sure about Sun

Does this happen if you do a test backup to a local Win2000 drive?

Just trying to rule out whether this is a Media or Disk agent problem.

Did you use a manual install or HP-UX installation server method to install the client? You could patch the installation server and push out the upgrade to the client which will probably fix the problem.

You can contact me through Paul Tacq of Morse Professional Services if you need further help.

Hi,
in /etc/system file (in solaris) increase the
number of shmmax,shmmni and shmseg parameters.
and reboot the system.this may solve ur problem

Ive got past the shared memory issue by adding the following lines to /etc/system

set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmseg=20
set shmsys:shminfo_shmmni=100

Unfortunately, another issue has now arisen, which i have posted in a new message.
