Features not support in system containers

Reading the HP-UX Containers 03.01 release notes I see that the following features are not supported in a system container:

1. POSIX IPC objects namespace

2. NFS server

 

1. Does this mean no support for semaphores or shared memory IPC?  ie would stop me running Sybase in a system container?

2. Is there a workaround for this?  Such as, would it be possible to export from the host, not the container and how would that work with respect to object locks etc?

 

Thanks in advance.

I assume these are POSIX named semaphores, created with sem_open(2) vs semget(2).

Or POSIX shared memory, created with shm_open(2) vs shmget(2) or open(2).

Do you know what Sybase uses?

 

>2. would it be possible to export from the host?

 

Yes, that sounds like it.

1. Dont know what Sybase uses, I am just a user.  When did HP-UX go to Posix?  Was it 11iv1 or before then (11.00?);

 

thanks for response.

You can always use elfdump/odump to look at the imports.

It's been some time.
