That’s not a child channel, those are different constructs. Config channels contain configuration files, child channels contain RPMs and are subordinate to base distribution channels. I suspect the function call you’re really looking for is system.setChildChannels. That will also require getting the set from system.getChildChannels and add your new value to the set.<o:p></o:p> <o:p> </o:p> Secondly, that sort of error usually indicates that there’s an error in arguments. The function call processing uses argument types to route function calls based on arguments lists.<o:p></o:p> <o:p> </o:p> $systemInChanel = $client->call('system.config.addChannels', $session, $record, $chanel, $client->boolean($isDir));<o:p></o:p> <o:p> </o:p> Arg1 is good, that’s your basic function call.<o:p></o:p> Arg2 is your session set, also good.<o:p></o:p> Arg3… based on the docs I’m looking at, it should be an array, ot a solitary value, of system IDs.<o:p></o:p> Arg4… also should be an array, of configuration channel labels.<o:p></o:p> Arg5, good, Boolean value.<o:p></o:p> <o:p> </o:p> Try this:<o:p></o:p> <o:p> </o:p> $systemInChanel = $client->call('system.config.addChannels', $session, ( $record ), ( $chanel ), $client->boolean($isDir));<o:p></o:p> <o:p> </o:p> to set arg3 and arg4 into a list prior to passing the argument list.<o:p></o:p> <o:p> </o:p> Jeff Kalchik<o:p></o:p> Systems Engineering<o:p></o:p> Land O’Lakes<o:p></o:p> <o:p> </o:p> <div> <div style="border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in"> From: spacewalk-list-bounces@redhat.com [mailto:spacewalk-list-bounces@redhat.com] On Behalf Of Tânia Agulhas Marques Valente [EE] (SSI) Sent: Monday, December 18, 2017 4:48 AM To: spacewalk-list@redhat.com Subject: [Spacewalk-list] Question about perl with API<o:p></o:p> </div> </div> <o:p> </o:p> Hello<o:p></o:p> <o:p> </o:p> I am trying to make a perl script to add a child channel to a client system in Spacewalk.<o:p></o:p> I am relatively new with perl , managed to already make some that really help me a lot and I wanted to go further.<o:p></o:p> <o:p> </o:p> But I am getting an error and it seems I am not getting nowhere.

Both must be arrays, and that’s why I make a list in a file and pass it on command line (even though this test only have an entry on each file/list), I have used this before in other scripts and it worked, so I am getting to a dead end I believe because of my lack of knowledge in perl. But you must have an objective to write a script so I am learning when I need it.<o:p></o:p> <o:p> </o:p> Maybe someone already used this API call and can help me.<o:p></o:p> <o:p> </o:p> <o:p> </o:p> Thank you<o:p></o:p> <o:p></o:p> <o:p> </o:p> <o:p> </o:p> </div> This message may contain confidential material from Land O'Lakes, Inc.
