This is a little story of a little bug. This gremlin suddenly appeared in a CGI.PM web-based application I work with. To make a long story short, an email was coming out something like this . . . I discovered that the page was in fact receiving three values for CGT::param(“rep_no”) when user was of type ‘B’, and thus sending that as an array to the send_TXT_email method, and as a result, buggering up the email content. Even more digging I found out the root cause was a web page that was three pages back from the one that was sending the email. Here’s the quick fix.
Once more, the Ottawa Perl Mongers assemble! I’ll be presenting on how I’m implementing AJAX forms in a Catalyst application, using the deadly magic of Mason, Prototype, and FormFu. Pizza will be graciously provided by Pythian. So if you plan on coming, please let me know so that I can be a good little ninja and make the number of slices match the number of attendees.
Good morning and happy Friday to all. Happy Thanksgiving to all of our friends, family, acquaintances, and well-wishers in the US. Enjoy the turkey and the football. As always, there’s not shortage of news stories, though the week seemed a bit slow because of the holiday. Here are some things we thought were interesting this week.
One of our clients has a public web page and they needed to ensure that it is always up and accessible. Pythian already has a monitoring stack that includes website and pages monitoring. I wondered if this could be done from SQL Server using built-in Windows modules to access external web resources. There are various the methods we can use.
I had an opportunity over the past few days to attempt to use Microsoft’s Server Management Objects (SMO) with Perl to manage a SQL Server 2005 DB. To make a long story into a short post, I blundered into the Win32::CLR module on CPAN, a little gem from Toshiyuki Yamato. Here is all you need to get started.
Is it Friday already? Where has the week gone? Whatever, we’ve got lots of good news tidbits for you this week, including several follow-ups to previous stories. Enough jaw-jacking, let’s get to the news.
This is the 170th edition of Log Buffer, the weekly review of database blogs. Welcome. Let’s kick off this week with a double-helping of . . .
I recently nominated my colleague and good friend Christo Kutrovsky for the Oracle ACE program. Today, I’m excited to share that he has been accepted and is now part of the community of 200+ Oracle ACEs and Oracle ACE Directors.
Like good day and welcome to issue 6 eh. This is another light one as it’s been another busy week. I have not had any time of my own to crawl through the news, but luckily my cohort Bill has flagged some good stuff for this week. Let’s get to it.
Here is a must-read whitepaper describing SQL Server Scheduling and how to interpret and diagnose Errors 17883, 17884, 17887, and 17888; please look here How To Diagnose and Correct Errors 17883, 17884, 17887, and 17888. We had a client having same issue. The client runs a busy online business with thousands of connected users; databases sometimes include more than half a million tables. We had a healthy counters and server didn’t seem to suffer from memory or I/O bottlenecks. We did suspect, that it is something to do with SQL Server internals, as we also received fatal exceptions pertaining to SPIDs <50 (system processes). If you face similar issues, you should install the latest service pack and cumulative update, and check if you have any resource bottlenecks. You can try trace T2330 as well, and if you still get errors or dumps, then you had better open a case with Microsoft Support to analyze the dumps and provide a resolution.
