DEBUG apps with SYS$ICC

[Ruslan R. Laishev]

Hi All!
I have some application written some time ago, now I have some problem with it. This app. use SYS$ICC* service to communitactin with other processes...

Is there a facilities to get some information about SYS$ICC* context/primitives/handles ?
SDA, DEBUG ?

[Ian Miller.]

There is a IPC SDA extension - I can't find any documentation for it
(see [TPSSDA]IPC$SDA*.* on the listings CD)

Ruslan,

The $ICC sysem services, and how to use them, are well documented.
See:
http://h71000.www7.hp.com/doc/82FINAL/5841/5841pro_007.html#intra_cluster_sec
and the System Services eference Manual.
Regards,
Kris (aka Qkcl)

Hello Ian,

I found nothing related to ICC in the 7.3 listings

Anyway thanks!

[Ruslan R. Laishev]

Thanks, Kris. I read the docs BEFORE programming the apps. :-)

I think the IPC$SDA* routines display data about the $ICC usage.

[Ruslan R. Laishev]

Hi, Ian!

I cannot see with SDA/IPC anything what is can interprete as my ICC associations...

[Volker Halle]

Ruslan,

the ICC code (within the SYS$IPC_SERVICES execlet) is - by default - not compiled with debug or trace support by OpenVMS engineering. If you want or need tracing from ICC, you might need to log a call with HP and ask for a SYS$IPC_SERVICES execlet with debug/trace support linked in.

Ruslan,

the only kind of 'trace' available for ICC (out-of-the-box) would be OpenVMS System Service Logging (available in V8.2 or higher). It would at least allow you to trace the various SYS$ICC* system service calls, that your application is invoking.

But as you've said you've written your application 'some time ago', your systems may not yet be running V8.2

Thanks, Volker!

At the time I'm need to get some basic information about ICC primitives on working application: state, connections, message size and queue length...

[Volker Halle · Accepted solution]

Ruslan,

some of the SDA> IPC commands do show ICC related data structures:

SDA> IPC SHOW ASSOC/SYSIPC ! shows ipcids for ICC
SDA> IPC SHOW ASSOC/SYSIPC/IPCID=ipcid
SDA> IPC SHOW LINK/IPCID=ipcid

I'm using the ICC VERY_SIMPLE_SERVER example to confirm, that ICC associations are shown.

Volker.

Hi, Volker!

What is VMS version ?

[Ruslan R. Laishev]

Hi, Volker!

My error was that I used:
sda>ipc sho ass

instead of

sda>ipc sho ass/sysipc

Cool Thanks!

[Ruslan R. Laishev]

Thanks for all responders.
