vtserver startup warnings

[jrzhou]

We upgrade to VTune 7.0 recently. We want to use remote linux data collection on a RedHat 9 machine. We do successfully compile the drivers using vdk_918. But when we start vtserver, there are warnings about IPC messages and shared memory segements. Is this important? If we don't want to remove them, what happens?

I list the message I got as below:

Setting up ISM environment ...
Setting up Callgraph environment ...

One or more IPC messages have been detected:

------ Message Queues --------
key msqid owner perms used-bytes messages
0x0003d138 0 jrzhou 666 0 0
0x000d237c 32769 jrzhou 666 0 0


Remove these IPC messages? ([Yes]/no)

Removing the following IPC messages: 0 32769

One or more IPC shared memory segments have been detected:

------ Shared Memory Segments --------

0x00000000 32768 jrzhou 777 393216 2 dest

0x00000000 3473410 root 644 98304 2 dest

Remove these IPC shared memory segments? ([Yes]/no)

Thanks.

I've forwarded your very well-detailed report to some of the engineers, jrzhou!

Stay tuned...

Direct from Engineering:

we do not support RH9 on VTune 7.0 however I advise to try using the backward compatibility mode of RH9 - set the environment variable LD_ASSUME_KERNEL to the value 2.2.5 and then run vtserver again (its not supported mode but its worth trying) 7.1 FCS will support the updated RH9 (with the relevant updated NPTL packages such as glibc and kernel)

regarding the IPC?s - vtserver warns the user on any open IPC resource no matter if it?s a left over of VTune or not and it is up to the user to decide whether to delete it or to leave it as is, according to the log he attached it looks like the IPC?s will not affect the run

Thanks, Jeff.

I've tried VTune7.1 Beta. The warnings go away.

Thanks for the follow up!
