Well, now that everyone and their mother has seen Googlemaps, all I keep hear from my clients is "can you make it pan like googlemaps?". To be honest, I had thought about doing something exaclty like it several years back, but dismissed the idea thinking no one would really want that anyway. Boy, was I wrong.
So, I thought I'd investigate the possibiity of making my own fancy pan function. I suppose if I had 3 gazillion dollars like google, I could make it do whatever I want. So, it looks like its being done with some kind of AJAX implementation.
I have heard some rumblings about the new ArcExlorer client using AJAX, but I was wondering if there is anyone out there doing this with ArcIMS yet? If not, its inevitable that we'll see one soon. If you have doing some experimenting already with AJAX/ARCIMS, I'd like to hear from you.
As we all probably know, ArcIMS and other ESRI products eat lots and lots of ArcSDE connections. Sometimes ArcSDE can even (gasp) leave orphaned connections out there. To overcome these issues, I always bump up my number of available connections.
I find myself refering to these instructions, emailing them, talking people through this over the phone, etc, quite often. This is a huge deal, but I don't feel that ESRI has stressed this enough. It used to be totally undocumented but now it is mentioned in the Config and Tuning guide for Sql Server and there is a knowledge base article found here. But, I thought I would post the info here just as a friendly reminder.
First, bump up the allocated memory: The size of the interactive and non-interactive desktop heaps is determined by a registry setting under \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems. Within the 'Windows' string value, there is a 'SharedSection' parameter that by default should read: SharedSection=1024,3076,512 Change the 512 to 1024
To bump up the number of available SDE connections, you need to now edit the SDE_server_config table-->prop_name-->connections change that value to the number of connections you need. Don't go overboard - just add what you need to be safe. See my previous posting for more info on how to do this.
Hey All...Just wanted to give you Southeast folks a quick heads up on a little demonstration that we will be giving on Integrating ArcIMS With ArcGIS Server. Its going to be Tuesday, August 30th in Atlanta.
So, now we have many more options with ArcGIS Server. Mixing the 2 products throughout the organization is going to become the hot topic in the future.
Some of the likely topics include:
* Using ArcGIS Server generated webservices through ArcIMS * Advanced backed editing * Mixing ArcServer Clients with ArcIMS clients throughout an organization * Real spatial analysis
Well, I suppose by now the conference is in full swing. Unfortunatley, I couldn't make it this year. But, after working on a grueling Routemap IMS Coldfusion project (yes, you did read that correct), I have decided to take a few days off and have a couple of my college buddies who I haven't seen in a while come down to visit.
I trust all you guys will let me know how the conference is going. I am especially interested to hear how the Coldfusion Arcims Users Group meeting went.
Hey all, unfortunately, I can't make it to this years meeting at the user conference, but fellow Coldfusion developer (and the creator of mapdex.org), Jeremy Bartley will be running the show. Here are the details of the meeting from Jeremy:
Fellow CF/ArcIMS developer-
You don't know me, but I am in charge of putting together the third annual ArcIMS-CF users group get-together at the ESRI users conference this year. The meeting will be on Thursday July 28 from 12:15-1:15 in room 3 (SDCC). We are pleased this year to have Mike Nimer of Macromedia attend our session. Mike is a ColdFusion MX engineer with experience building GIS applications. Mike also has extensive experience with CF Flash Forms that he can share with us. Margaret Lyszkiewicz from the ArcIMS development team at ESRI will also join us. Margaret is an accomplished developer who has been carrying the CF flag at ESRI for years. We are honored to have Mike and Margaret at our meeting this year. This is your chance to give advice to the developers of the software you use most (CF and ArcIMS).
Don’t miss it!
Hey there everyone. If you are like me, you have at one time or another in the past struggled with getting Tomcat to work on your IIs based machine. Just the other day, I struggled with an install, only to give up in frustration.
The specs were: Windows Server 2003 standard Tomcat 5.028 ArcIMS 9.1
No matter what I did I couldn't get this thing to redirect to IIs. Port 8080 worked like a champ, so I knew Tomcat itself was ok. There is just something funky with iis6 I suppose. Anyway, a coworker of mine, Big LU took over the install, and late last night, he was able to get it going. He used the attached guide to help him through the install. I wish I knew where this guide came from so that we could give them proper credit, but I just don't know.
So, if you are one of those folks currently struggling with the Tomcat redirector issue, check out this guide: Click the download link below.
This is just a reminder to all you old school SDE users...This one has caught me more than once. I just bumped up my connection limit, and was hittin my head against the wall as to why they were still being capped at 48. Remeber back in the day when you could just modify your dbtune.sde file or your giomgr.defs file, restart (arc)SDE and that was it? Well, just a reminder that you cant do that anymore. You need to make those changes and then use the appropriate command to import that file into your spatial database.
I know, most folks either started at version 9 or actually read instructions and already know to do this. But us old schoolers who started at (arc)SDE at version 3 have to be reminded sometimes.
One of these days I'm going to post the SDE Configuration and Tuning Guide for version 3 - all 11 pages of it, which I have saved for sentimental reasons, just to show you how tough we all had it back then. Whats that guide up too now? 200 + pages if I recall...
As many of you have read in the posting previous to this one, I have been doing a lot more direct connections to ArcSDE from ArcIMS. We'll I've been having a bit of trouble with a few things, but no big deal....However I did discover a few new things about ArcIMS 9.1.
I read about a new parameter for connection to ArcSDE on the ArcIMS whats new page:
"For Image and Feature services that use ArcSDE data, a new feature parameter defines the time interval between attempts to reconnect to ArcSDE when the SDE server becomes unavailable."
wOOt! Sounds great to me, so I go looking for it. Looks like its located in the %arcims install dir%\server\etc\aimssdeio.cfg. Open up that file and look at the new parameter connectioncheckinterval="300". First thing that came to mind for me was this is could be why it was taking my mapservices so freaking long to refresh (see this post for more info). I don't know that for sure, but I'm guessing that it is, so I immediately lowered that number to 20. I'll let you know what happens.
The next thing I noticed was a new log file getting created in that same etc directory called sdedc_SQL Server.log. Of course I check it out, because I am all about log files. Its a great start to just have a log file specifically for direct connections, but this didn't really contain a whole lot of useful information.
IDBInitialize::Initialize Failed CAN'T OPEN INSTANCE: sde:sqlserver. Spatial Engine Connection Failed (-9).
Yeah, I already know that. Thanks for nuttin. But, I applaud ESRI for recognizing the need for that log file, and I hope that with future releases, we'll get some more info. By the way, I left encrypted="true" in my sdeworkspace - and thats what threw the error above.
