Very strange... usually when we see this error
[80:1003] Cannot allocate/attach shared memory (IPC Cannot Create Shared Memory Segment
System error: [5] Access is denied.
) => aborting.
It is from a UNIX-based client, normally one of the non-Majors, like Solaris, or BSD Unix, or even on Linux. We have you either decrease some Media Agent Parameters, or increase the amount of Shared memory by tweaking UNIX kernel parameters
I don't think I have ever seen thsi on a Windows server. Heck, 'shared memory' is UNIX terminology
Having said this, I checked lab cases, found one going back to 2003, for Omniback 5.10 running on Windows 2000
The recommendation was to edit the file
Program Data -> Omniback -> omnirc
on your Oracle server 'host.my.domain.com'. This file does not exist by default, if you don't have it, you can start with a Blank Notepad. Add this line to the file
OB2SHMEM_IPCGLOBAL=1
Save the file as
Program Data -> Omniback -> omnirc
Make sure that teh filename has no extension, like 'txt' or 'tmpl'. On Windows systems, you must Stop and Start the Data Protector INET service to make the change take effect
