• hierarchy structure with nested set model

  Hello all, I'm wondering if anyone have had production experience with building hierchy structure using the nested set model (Joe Celko's)? I've ironed out the algorithem to do add, delete & move nodes with subtrees, but the issues comes to the UI part of it. Suppose I give users the ability to re-arrange all the menus / categories on the front end using javacript, how do you approach and update the new tree structure? User could completley change the tree structure, the only way

• Re: hierarchy structure with nested set model

  Thanks Guntman and Tusharrs. Ajax is definitely out for us because some of our users do not have MS Ajax installed, but it surely will solve the problem of postback everytime I re-order the tree. I'll look into JQuery / JSON.NET for that. Batch operation looks like the only way to go for now and that's just the thing that I'm having a hard time. If I do that, then the logic has to be moved from the back-end to the front end using javascript. hm... Thanks for the ideas. If you have any

• Re: hierarchy structure with nested set model

  Thanks gunteman. Actually, I meant my users as my customers. Our software can't use MS ajax because not all of our clients have MS ajax installed on their server. For our tree, basically, we have the users add categories and sub categories.(one at a time) The logic is currently in the store procedure. Now, we try to improve the user experience by allowing them to-re arrange the category structure. We first retrieve the entire tree out of database, presented on the UI and from there, using JQuery

• Looking for oldies, Atlas Wiki Source?

  Hello everyone, This goes back to the Atlas days, there was this Atlas wiki. Given how old it is, i'm wondering if anyone still have a copy of that? It can't be found anywhere from what I searched. If you have a copy, I'd appreciate it very much if you can give me a copy of it. Thanks

• Re: Oracle sessions and http sessions

  Thanks mamun22s. yeah, i figured the number of web session will not be one-to-one relationship to oracle session. The background story is that our oracle server is configured to have 50 concurrent session max. Now the traffic is using up all the 50 concurrent sessions and any other connection will get a maxium amount exceeded error. On one end, we will look into tweaking connection pooling parameters, but on the oracle side, not sure what to expect. Such i want to a ratio of "Web session / oracle

• Oracle sessions and http sessions

  Hello All, It's a stupid question. I'm a developer and I don't know oracle DBA nor any database server adminstration that much so i'm just wondering, if an Oracle server is configured to have 30 concurrent sessions, what's the equaivlent amount users from the web end generally speaking? 1000, 2000, 10,000, 100,000? Put in reverse, if a web site is expecting around 100k users a day, what are the general specifcs in terms of database server (concurrent sessions needed) and hardwares

• Re: 2 minutes before session timeout, warn the user and extend it

  Hey jagjot, forgot to mention, there is a blank "keepalive.aspx" in the directory. In the javascript code, after you clicked okay, an empty image object was costructed like so var img = new Image(1,1); img.src = 'KeepAlive.aspx?date='+escape(new Date()); that will hit the keepalive.aspx page and such extend the user session. As for the last piee of the code, users sometimes return to the window way after the warning period has expired. That was a measure to let the users know that

• Re: Table within Repeater

  Thanks RituB. I guess that's a limitation? The reason I create the "tr" only one time is because I see a significant performance issue when the table is genereated on the screen when the columns I have are increased to say more than 300 columns. I could actually see as each row is created as the page loads. Such the reason, I wanted to create only one row and re-use them as the repeater repeats. I'll keep on researching this. If you have any other suggestions that could overcome
