Setting up SMF for Apache and Zope on Solaris 10
by Chris Miles 02 Oct '05

02 Oct '05

For those running Solaris 10, I have documented a brief walk-through on how to configure Service Management Facility (SMF) for your Apache and Zope instances. This is the new Solaris 10 method of intelligently handling init.d/rc.d service management. http://systemsadmin.info/solaris/articles/setting-up-smf-for-apache-and-zop… Cheers, Chris -- http://chrismiles.info/

Re: [Zope] ZOPE and DEBIAN INSTALLTION

Hi Yes, I actually try to deinstall the latter "apt-get version" that I installed via source. But your solution does not work. After "reading the pakets", it is always said that the system could not find the paket "zope_2.6.4-1_i386.deb". The weird thing is that this paket is actually on system; I can even see it in my root directory! Do you know what problem is?

Problem with hasattr() and Zope 2.8.1
by Doyon, Jean-Francois 01 Oct '05

01 Oct '05

Hello, I'm using new-style classes and properties to implement multilingual support in my objects. I might therefore have something like: mything = property(__get_mything) def __get_mything: return self.__mything_en (Extremely simplified!) This works fine. Now however I'm discovering that doing a hasattr() on anything that starts with 2 underscores always returns false! So hasattr(self, '__thumbnail') doesn't work as expected, but hasattr(self, '_thumbnail') DOES! (All other things being equal of course). I've successfully tested this by replacing this code, which didn't work as expected: def __get_thumbnail(self): if not hasattr(self, '__thumbnail'): self.setThumbnail() return self.__thumbnail else: return self.__thumbnail With this one: def __get_thumbnail(self): try: return self.__thumbnail except: self.setThumbnail() return self.__thumbnail Which DID work as expected (Though I suspect the try ... except might be faster anyways!) ... I checked the Collector: http://www.zope.org/Collectors/Zope/collector_contents?searching=yep&Searcha bleText=hasattr&status%3Alist%3Aignore_empty=Accepted&status%3Alist%3Aignore _empty=Pending Nothing jumped out at me as being relevant ... Any ideas?

ZRS Now Available for FREE 30-day Evaluation
by Brian Lloyd 01 Oct '05

Hi all, We are happy to announce that Zope Corporation is now offering Zope Replication Services (ZRS) in a 30-day evaluation format! For more information and to download the evaluation release, visit: http://customers.zope.com/ZRS/ About ZRS: Zope Replication Services (ZRS) increases the reliability of all Zope enterprise clusters and eliminates the storage system as a single point of failure. Sites with high availability requirements must manage planned and unplanned downtimes. Planned outages include system maintenance, software / operating system upgrades, and backups. Unplanned outages include hardware and network failures. ZRS reduces the downtime associated with these events by replicating and distributing mission-critical data storage across distinct physical storages (possibly in distinct geographic locations). Should a primary storage fail, a secondary storage can take its place. Secondary servers can be taken off-line at any time to undergo repairs, backups, or system upgrades. When a secondary returns to service, it automatically resynchronizes with the primary server. ZRS also improves scalability since secondary servers can optionally provide additional read-only ZEO connections while maintaining their replication functions. ZEO client storages can be configured to connect to any available secondary, and can be load-balanced among the available secondary ZRS servers to implement highly-available and highly-scalable Zope clusters. ZRS is a 'battle-tested' solution that has provided the high-availability and disaster recovery solution critical to large-scale public and internal Zope deployments for years. Premier brands including the VIACOM radio and television group, AARP, Community Newspaper Holdings Inc. (CNHI), and the Joint Intelligence Center, Pacific (JICPAC) rely on ZRS to ensure reliability and scalability for their mission-critical Web sites. The 30-day evaluation release allows organizations to install and operate ZRS on up to five primary ZODB servers and on an unlimited number of secondary servers for up to thirty days. The current evaluation release (ZRS 1.4.2) is compatible with Zope versions 2.4 - 2.7. Full releases of ZRS compatible with Zope 2.8.x and Zope 3.x are also available.
