Re: pca-proxy.cgi questions My team has simultaneously patched as many as 1000 Solaris servers a night through the pca proxy without incident. As long as your infrastructure (i.e, network, pca webserver proxy) can handle the load pca should function without incident.
My current struggle is locating something that will work for Solaris 11 as fantastically as what Martin has put together for pre-Solaris 11 Jeff ☺ -----Original Message----- From: pca-boun...@lists.univie.ac.at [mailto:pca-boun...@lists.univie.ac.at] On Behalf Of pca-requ...@lists.univie.ac.at Sent: Tuesday, February 21, 2012 6:00 AM To: pca@lists.univie.ac.at Subject: pca Digest, Vol 49, Issue 17 Send pca mailing list submissions to pca@lists.univie.ac.at To subscribe or unsubscribe via the World Wide Web, visit https://lists.univie.ac.at/mailman/listinfo/pca or, via email, send a message with subject or body 'help' to pca-requ...@lists.univie.ac.at You can reach the person managing the list at pca-ow...@lists.univie.ac.at When replying, please edit your Subject line so it is more specific than "Re: Contents of pca digest..."

Basic steps: - Mount media (NFS from a Jumpstart or DVD or even ISO using lofiadm) on the system to be upgraded - Uninstall the LiveUpgrade packages (SUNWlucfg and related packages) from the current system - Install the LiveUpgrade packages from the new release's media - Use LiveUpgrade to create an Alternate Boot Environment - Run the LiveUpgrade tools against the ABE but use the new release's media as the source - luactivate the ABE - reboot - profit! You can even LiveUpgrade from UFS to ZFS root if you desire, but I would not recommend going to a new release and ZFS simultaneously. Instead, do it as separate LiveUpgrade activities to limit the scope of your changes in case there is an issue. Also, another plus for LiveUpgrade: If things go South, remember that you can always boot from alternate media and use "luactivate" to roll back your changes and boot the previous BE.

That's no problem, PCA takes care of that. When a client asks for a patch which is currently being downloaded due to some other request, PCA will complete the download and then deliver the patch to both clients. This seems to be pretty robust, I can't remember any recent problem reports about such issues. > We plan to have a few hundred servers downloading patches at one time. > Will this be fine? Anybody else already doing this? I don't have hundreds of clients, but I've heard from others that have. So this should be fine. If you do experience any trouble, let me know. Even more, tell us when you have your setup running and working - success stories are always welcome :) If you want to spread the load to multiple servers, you might be interested to hear that you can even build a cascade of pca proxies - just point one proxy at another by setting xrefurl/patchurl on a secondary proxy to the primary proxy. hth, Martin. ------------------------------ _______________________________________________ pca mailing list pca@lists.univie.ac.at https://lists.univie.ac.at/mailman/listinfo/pca End of pca Digest, Vol 49, Issue 17 ***********************************
