• Data from a table in 1 DB needed for filter in different DB...

  - by Refracted Paladin

  I have a Win Form, Data Entry, application that uses 4 seperate Data Bases. This is an occasionally connected app that uses Merge Replication (SQL 2005) to stay in Sync. This is working just fine. The next hurdle I am trying to tackle is adding Filters to my Publications. Right now we are replicating 70mbs, compressed, to each of our 150 subscribers when, truthfully, they only need a tiny fraction of that. Using Filters I am able to accomplish this(see code below) but I had to make a mapping table in order to do so. This mapping table consists of 3 columns. A PrimaryID(Guid), WorkerName(varchar), and ClientID(int). The problem is I need this table present in all FOUR Databases in order to use it for the filter since, to my knowledge, views or cross-db query's are not allowed in a Filter Statement. What are my options? Seems like I would set it up to be maintained in 1 Database and then use Triggers to keep it updated in the other 3 Databases. In order to be a part of the Filter I have to include that table in the Replication Set so how do I flag it appropriately. Is there a better way, altogether? SELECT <published_columns> FROM [dbo].[tblPlan] WHERE [ClientID] IN (select ClientID from [dbo].[tblWorkerOwnership] where WorkerID = SUSER_SNAME()) Which allows you to chain together Filters, this next one is below the first one so it only pulls from the first's Filtered Set. SELECT <published_columns> FROM [dbo].[tblPlan] INNER JOIN [dbo].[tblHealthAssessmentReview] ON [tblPlan].[PlanID] = [tblHealthAssessmentReview].[PlanID]

• Session timeout issue

  - by Kumar

  I have a role based ASP.NET C# web application in which I am putting the menu object inside a session and I have a session timeout configured in the web.config as below: <forms defaultUrl="Home.aspx" loginUrl="Login.aspx" name=".ASPXFORMSAUTH" timeout="10"></forms> I first logged into the system as an employee and waited until the session expires and then when I click a link in the menu I am being rightly redirected to the login page with the ReturnUrl parameter. Now when I try to login to the system as an administrator I am still seeing the employee menu and not the admin menu. The method which loads the menu 1st checks to see if the menu session object is not null if so loads the menu from the session if not then it builds the menu and put it into session. So when the system timesout the menu session object is not being cleared. How can I fix this?

• Servlet Session - switch from URL Rewriting to Cookie

  - by lajuette

  Situation: I have a "dumb" Javascript frontend that can contact some kind of SSO middleware (MW). The MW can obtain sessions by issuing requests that contain authentication credentials (username, password). I.e. the session will be created for a certain user. My frontend needs to "restart" the session to gain the user's permissions to the target system. For that i need a valid session cookie. The target system is not under my control (could be a more or less public WFS, WMS, etc.), so i cannot add any SSO mechanism to it. Question: Is it possible to "steal" a Session forging a request which URL contains a valid session ID in the jsessionid parameter? Goal : Issue such a request to a Servlet and make it respond with a Set-Cookie header that contains the same id. That way the frontend joins the session and may do whatever the user, which was used to create the session, is able to do.

• Selectively prevent Session from being created

  - by Jean Barmash

  In my app, I have an external monitor that pings the app ever few minutes and measures its uptime / response time Every time the monitor connects, a new server session is created, so when I look at the number of sessions, it's always a minimum of 15, even during times where there are no actual users. I tried to address this with putting the session creation code into a filter, but that doesn't seem to do it - I guess session automatically gets created when the user opens the first page? all() { before = { if (actionName=='signin') { def session = request.session //creates session if not exists } } } I can configure the monitor to pass in a paramter if I need to (i.e. http://servername.com/?nosession, but not sure how to make sure the session isn't created.

• What scripts get run on session start and end?

  - by maaartinus

  I want to mount and unmount an encrypted partition just like ecryptfs works with the home partition. Where can I put my commands so that they get executed upon session start and session end (the important part is the unmounting when I log out). UPDATE: For the session start I'm using .gnomerc and it does what I want. For the session end I've found no solution. I had a look at the sources of ecryptfs and it looks quite complicated. It's a pity that nobody thought about creating something analog to .bash_logout.

• Rails - session information being cleared?

  - by Jty.tan

  Hi! I'm having a weird issue that I can't track down... For context, I have resources of Users, Registries, and Giftlines. Each User has many Registries. Each Registry has many Giftlines. It's a belongs to association for them in a reverse manner. What is basically happening, is that when I am creating a giftline, the giftline itself is created properly, and linked to its associated Registry properly, but then in the process of being redirected back to the Registry show page, the session[:user_id] variable is cleared and I'm logged out. As far as I can tell, where it goes wrong is here in the registries_controller: def show @registry = Registry.find(params[:id]) @user = User.find(@registry.user_id) if (params[:user_id] && (@user.login != params[:user_id]) ) flash[:notice] = "User #{params[:user_id]} does not have such a registry." redirect_to user_registries_path(session[:user_id]) end end Now, to be clear, I can do a show of the registry normally, and nothing weird happens. It's only when I've added a giftline does the session[:user_id] variable get cleared. I used the debugger and this is what seems to be happening. (rdb:19) list [20, 29] in /Users/kriston/Dropbox/ruby_apps/bee_registered/app/controllers/registries_controller.rb 20 render :action => 'new' 21 end 22 end 23 24 def show => 25 @registry = Registry.find(params[:id]) 26 @user = User.find(@registry.user_id) 27 if (params[:user_id] && (@user.login != params[:user_id]) ) 28 flash[:notice] = "User #{params[:user_id]} does not have such a registry." 29 redirect_to user_registries_path(session[:user_id]) (rdb:19) session[:user_id] "tester" (rdb:19) So from there we can see that the code has gotten back to the show command after the item had been added, and that the session[:user_id] variable is still set. (rdb:19) list [22, 31] in /Users/kriston/Dropbox/ruby_apps/bee_registered/app/controllers/registries_controller.rb 22 end 23 24 def show 25 @registry = Registry.find(params[:id]) 26 @user = User.find(@registry.user_id) => 27 if (params[:user_id] && (@user.login != params[:user_id]) ) 28 flash[:notice] = "User #{params[:user_id]} does not have such a registry." 29 redirect_to user_registries_path(session[:user_id]) 30 end 31 end (rdb:19) session[:user_id] "tester" (rdb:19) Stepping on, we get to this point. And the session[:user_id] is still set. At this point, the URL is of the format localhost:3000/registries/:id, so params[:user_id] fails, and the if condition doesn't occur. (Unless I am completely wrong .<) So then the next bit occurs, which is (rdb:19) list [1327, 1336] in /Library/Ruby/Gems/1.8/gems/actionpack-2.3.5/lib/action_controller/base.rb 1327 end 1328 1329 def perform_action 1330 if action_methods.include?(action_name) 1331 send(action_name) => 1332 default_render unless performed? 1333 elsif respond_to? :method_missing 1334 method_missing action_name 1335 default_render unless performed? 1336 else (rdb:19) session[:user_id] "tester" And then when I hit next... (rdb:19) next 2: session[:user_id] = /Library/Ruby/Gems/1.8/gems/actionpack-2.3.5/lib/action_controller/filters.rb:618 return index if nesting != 0 || aborted (rdb:19) list [613, 622] in /Library/Ruby/Gems/1.8/gems/actionpack-2.3.5/lib/action_controller/filters.rb 613 private 614 def call_filters(chain, index, nesting) 615 index = run_before_filters(chain, index, nesting) 616 aborted = @before_filter_chain_aborted 617 perform_action_without_filters unless performed? || aborted => 618 return index if nesting != 0 || aborted 619 run_after_filters(chain, index) 620 end 621 622 def run_before_filters(chain, index, nesting) (rdb:19) session {:user_id=>nil, :session_id=>"49992cdf2ddc708b441807f998af7ddc", :return_to=>"/registries", "flash"=>{}, :_csrf_token=>"xMDI0oDaOgbzhQhDG7EqOlGlxwIhHlB6c71fWgOIKcs="} The session[:user_id] is cleared, and when the page renders, I'm logged out. .< Sooo.... Any idea why this is occurring? It just occurred to me that I'm not sure if I'm meant to be pasting large chunks of debug output in here... Somebody point out to me if I'm not meant to be doing this. . And yes, this only occurs when I have added a giftitem, and it is sending me back to the registry page. When I'm viewing it, the same code occurs, but the session[:user_id] variable isn't cleared. It's driving me mildly insane. Thanks!

• Pass Session data to a Class Library without using a bunch of constructors?

  - by sah302

  Hi all, I've got my application here where literally every object has a lastUpdatedBy property. The information I put into here is the person's username, which is retrieved from the session("username") variable. How can I pass this data to my DAL in the class library? At first I was just passing in the value into each method, but this is ridiculous I thought, there should be no reason to do that every time a method is called. Then I thought well if I just put it in a constructor for each of the DAL related classes, that will make it even easier. However, even still on any given page, I've got a plethora of New() declarations, for which every single line I need to pass in the session username casted as a string. Is there an even still more efficient way of doing this so that I could only declare this in one place, and everything will know what it is and I can pass it to classes in a class library?

• Session State ArrayList in Shopping Cart ASP.NET

  - by user330342

  Hi guys, I'm creating a shopping cart application and I'm having some issues with implementing a session state for my arraylist. in my page load i declared if (Session["Cart"] == null) { Session["Cart"] = new ArrayList(); } else { ArrayList cart = (ArrayList)Session["Cart"]; } to create the session if it doesn't exist yet. then i have an event handler for a button to add items to the arraylist protected void onClick_AddBooking(object sender, EventArgs e) { int ClassID = Convert.ToInt32(Request.QueryString.Get("Class_Id")); ArrayList cart1 = new ArrayList(); cart1 = Session["Cart"]; cart1.Add(ClassID); i'm guessing i just don't know how to handle session states yet, thus the confusion. I'm essentially storing the class_ID then when the student confirms i'll store that to the DB and associate that ID with the Class Details. Thanks in advance guys!

• How to synchronize two (or n) replication processes for MS SQL databases?

  - by Yauheni Sivukha

  There are two master databases and two read-only copies updated by standard transactional replication. It is needed to map some entity from both read-only databases, lets say that A databases contains orders and B databases contains lines. The problem is that replication to one database can lag behind replication of second database, and at the moment of mapping R-databases will have inconsistent data. For example. We stored 2 orders with lines at 19:00 and 19:03. Mapping process started at 19:05, but to the moment of mapping A database replication processed all changes up to 19:03, but B database replication processed only changes up to 19:00. After mapping we will have order entity with order as of 19:03 and lines as of 19:00. The troubles are guaranteed:) In my particular case both databases have temporal model, so it is possible to fetch data for every time slice, but the problem is to identify time of latest replication. Question: How to synchronize replication processes for several databases to avoid situation described above?

• Database cluster... without Master/Slave?

  - by RadiantHex

  Hi there! I'm wondering if it is possible to have a set of SQLdb servers to which data is written and have them replicate, avoiding conflicting information. I imagine that a Master/Slave structure would be mandatory, I would like to know if a system where servers have no hierarchy could support replication. Currently I'm using MySQL, but I would be happy to move to another database if needed. Any ideas? :)

• How to restore a previous firefox session?

  - by jae

  FF 3.5.4 on Ubuntu 9.10. I have (of course) session saving (the built-in one) enabled. I closed the main FF window, but the "Downloads" window was still open. And on reopen, it had forgotten about the previous tabs. This is annoying is hell, and yes, I should report (or check for) a bug. If I could stomach bugzilla, that is. :P I have the sessionstore.js file with this older session (scanning it with less showed many of the sites I know had been open). How do I get FF to use this session file? I did try to remove sessionstore.* and copy the sessionstore.js (or .bak) to the profile folder. But that doesn't have any effect. EDIT: rewritten, to make it as obvious as it can be. I wasn't expecting people to jump to the "this guy's a stupid git" quite so easily.

• send command to an already running screen session

  - by aXon

  Hi I have been trying to send commands to a running gnu screen session (4.00.03) in opensolaris, but cannot get it to run any commands through any combination of screen -X Ok, I start a screen session with screen -S test, and then tried to with screen -r -X "date"to just show me the date, when I would reconnect to it. But neither an error message nor output in the screen happened. I tried with so many combinations, that I can't even remember. Any hints on how to accomplish it? The reason why I am doing this is, because I have a program, which does not come as a daemon, and I wish to start it in a screen session, so I can later on see what is going on.

• Remote Assist Windows 2008 R2 Session

  - by cbergman

  As mentioned in this kb article, it is not possible to shadow a session with multiple monitors enabled. It does mention that "Remote Assistance supports multiple monitors, and is the presently recommended solution if you need this functionality." My question is, is it possible (and if so, how) to remote assist a terminal services session. We have a few Windows Server 2008 R2 Terminal Servers running with about 10 or so users that use 2 monitors. It would be ideal to be able to remote into their session but have yet to find a viable solution. Thank you.

• hibernate and ehcache replication

  - by cachingsol

  Hi, I am working on a cache replication solution between nodes Node A - master node = Hibernate + Database + Ehcache as secondary cache Node B - regional node= Ehcache as prmiary cache. no Hibernate Node B is used only as near-by cache for query. Now I am updating data (Say SudentInfo) in Node A, it gets persisted and cached correctly. On replication side (I am using JMS) it sends a message to Node B. But the problem is, the message it sends is of instance CacheEntry(deep Inside Element), there is no way to resurrect the original object (StudentInfo). What I got in node B is CacheEntry with some attributes of Students but not actually an Student Object. Please note that I don't need Hibernate session/persistence in Node B, node B is only for fast query, persistence is done through Node A. So has anybody tried any solution like this? Is there any way to convert CacheEntry to actual object? or Tell ehcache to replicate original object rather than CacheEntry. Thanks for the help

• How to break a Hibernate session?

  - by Péter Török

  In the Hibernate reference, it is stated several times that All exceptions thrown by Hibernate are fatal. This means you have to roll back the database transaction and close the current Session. You aren’t allowed to continue working with a Session that threw an exception. One of our legacy apps uses a single session to update/insert many records from files into a DB table. Each recourd update/insert is done in a separate transaction, which is then duly committed (or rolled back in case an error occurred). Then for the next record a new transaction is opened etc. But the same session is used throughout the whole process, even if a HibernateException was caught in the middle. We are using Oracle 9i btw with Hibernate 3.24.sp1 on JBoss 4.2. Reading the above in the book, I realized that this design may fail. So I refactored the app to use a separate session for each record update. In a unit test with a mock session factory, I could prove that it is now requesting a new session for each record update. So far, so good. However, we found no way to reproduce the session failure while testing the whole app (would this be a stress test btw, or ...?). We thought of shutting down the listener of the DB but we realized that the app is keeping a bunch of connections open to the DB, and the listener would not affect those connections. (This is a web app, activated once every night by a scheduler, but it can also be activated via the browser.) Then we tried to kill some of those connections in the DB while the app was processing updates - this resulted in some failed updates, but then the app happily continued. Apparently Hibernate is clever enough to reopen broken connections under the hood without breaking the whole session. So this might not be a critical issue, as our app seems to be robust enough even in its original form. However, the issue keeps bugging me. I would like to know: Under what circumstances does the Hibernate session really become unusable after a HibernateException was thrown? How to reproduce this in a test? (What's the proper term for such a test?)

• Client-side Replication for SQL Server?

  - by Mighty Z

  I'd like to have some degree of fault tolerance / redundancy with my SQL Server Express database. I know that if I upgrade to a pricier version of SQL Server, I can get "Replication" built in. But I'm wondering if anyone has experience in managing replication on the client side. As in, from my application: Every time I need to create, update or delete records from the database -- issue the statement to all n servers directly from the client side Every time I need to read, I can do so from one representative server (other schemes seem possible here, too). It seems like this logic could potentially be added directly to my Linq-To-SQL Data Context. Any thoughts?

• Database Replication OOD Pattern

  - by MrOnigiri

  Greetings fellow overflowers, After reading on MSDN about correct strategies on how to perform database replication, and understanding their suggestion on Master-Subordinate Incremental Replication. It left me wondering, what OOD design pattern should I use on this... The main elements of this strategy are the Acquirer, the Manipulator and the Writer. The first fetches data from the database and passes on to the second which might perform simple transformations to the data, before handling it to the final element, the writer, that writes the desired data on the destination Database. I thought about using the Chain of Responsibility pattern, but the Acquirer, Manipulator and Writer don't share a common role among theme, so It makes no sense. Should these elements be written as separate classes, or methods inside my service? Of course I'll be creating a DB Helper class as well, but that doesn't constitutes a problem. Wondering what your opinions on this are! Thanks for your replies

• Best implementation for MySQL replication with Rails 3?

  - by vonconrad

  We're looking at potentially setting up replication for our primary MySQL database, and while setting up the replication seems pretty straight-forward, the application implementation seems a bit murkier. My first idea would be to set up a master-slave configuration and RW-splitting, with all write queries (CREATE, INSERT, UPDATE) going to master, and all read queries (SELECT) going to slave. Having read up on it, it seems that there are essentially two options for how to implement this with our app: Using an independent middleware layer for all MySQL connections, such as MySQL proxy or DBSlayer. However, the former is in Alpha and the latter has limited documentation. Using a Ruby-based gem/plugin, such as Octopus to achieve RW-splitting in the framework. If we wanted to go with a master-slave setup, what you recommend moving forward? The other thought I've had was to use a master-master configuration, but am unsure about the implementation of such a setup. Thoughts?

• Articles about replication schemes/algorithms?

  - by jkff

  I'm designing an hierarchical distributed system (every node has zero or more "master" nodes to which it propagates its current data). The data gets continuously updated and I'd like to guarantee that at least N nodes have almost-current data at any given time. I do not need complete consistency, only eventual consistency (t.i. for any time instant, the current snapshot of data should eventually appear on at least N nodes. It is tricky to define the term "current" here, but still). Nodes may fail and go back up at any moment, and there is no single "central" node. O overflowers! Point me to some good papers describing replication schemes. I've so far found one: Consistency Management in Optimistic Replication Algorithms

• PHP: Over-writing session variables

  - by Tom

  Hi, Question related to PHP memory-handling from someone not yet very experienced in PHP: If I set a PHP session variable of a particular name, and then set a session variable of the exact same name elsewhere (during the same session), is the original variable over-written, or does junk accumulate in the session? In other words, should I be destroying a previous session variable before creating a new one of the same name? Thank you.
