  • Memcached in a trusted shared environment?

    - by John Kary
    We are a university IT organization that hosts all of the university's websites on several shared servers on our server room floor. We have several VMs, each running its own instance of Apache as a web server for each respective server. If we were going to setup a memcached server, is it feasible to use it as a shared instance? If shared by several servers, or even multiple web apps running on the same server, what's the best way to keep each app's cache stores separate? Prefix the key? Would each VM require its own instance of memcached, or could we setup 1 memcached server and allow our multiple VMs to read/write to it?

  • How do you insert new entries into an Access db table through an ASP.net website?

    - by CGF
    I need to insert new records into an Access database. I'm using Visual Studio 2008 and firstly create a asp.net website. I can connect to the information in Access databse using dataview or gridview and can query a particular entry (ie. Proposal No. -brings up all details linking to that proposal). I can then edit the details of that proposal and this would update the Access Db. What I need to do is to have a form that simply enters new details for a new customer. ie. Enter name [__] Enter Adress[__]. Then for this to update the database. By using the gridview or dataview I am able to view all fields that exist in the table and edit them. Is there a way that I can get a blank gridview/dataview template (which includes all the fields in the table) and fill it out to then update the database? Thanks

    - by Mark
    I have an application that uses an access 2000 database currently in distribution. I need to update one of the recordsets with additional fields on my customer's computers. My data controls work fine as I have them set to connect in access 2000 format but when I try to open the database in code, I get an unrecognized data format error. What is the best way to replace or add to the database on their machines? Any help is greatly appreciated.

  • How much information do pdb files contain? (C# / .NET)

    - by Silver Dragon
    Is is wise to redistribute the pdb files along with a commercial application? Occasionally, I'm using the stack trace to get a more detailed error reporting logs from the deployed applications; can this functionality be achieved without relying to those files? Also, how much hints of the original source code does these files contain? Would it be easier to reverse-engineer my application using it?

  • Composable FLinq expressions

    - by Daniel
    When doing linq-to-sql in c#, you could do something like this: var data = context.MyTable.Where(x => x.Parameter > 10); var q1 = data.Take(10); var q2 = data.Take(3); q1.ToArray(); q2.ToArray(); This would generate 2 separate SQL queries, one with TOP 10, and the other with TOP 3. In playing around with Flinq, I see that: let data = query <@ seq { for i in context.MyTable do if x.Parameter > 10 then yield i } @> data |> Seq.take 10 |> Seq.toList data |> Seq.take 3 |> Seq.toList is not doing the same thing. Here it seems to do one full query, and then do the "take" calls on the client side. An alternative that I see used is: let q1 = query <@ for i in context.MyTable do if x.Param > 10 then yield i } |> Seq.take 10 @> let q2 = query <@ for i in context.MyTable do if x.Param > 10 then yield i } |> Seq.take 3 @> These 2 generate the SQL with the appropriate TOP N filter. My problem with this is that it doesn't seem composable. I'm basically having to duplicate the "where" clause, and potentially would have to duplicate other other subqueries that I might want to run on a base query. Is there a way to have F# give me something more composable? (I originally posted this question to hubfs, where I have gotten a few answers, dealing with the fact that C# performs the query transformation "at the end", i.e. when the data is needed, where F# is doing that transformation eagerly.)

  • Access database Need to prevent from approving overlapping OT.Second Try with modified request Not a programmer [on hold]

    - by user2512764
    Employees Signups on company Website for advance overtime line. Access table already has overtime signups which does not require user to add the time but it requires only to add location as approved. Since this table has field Employee name, Date, start time and End time and location, All the fields has the data except for location. In the data base I have created a form based on this table. Since the table already have most of the information User only has to add location in the form field in order to approve overtime. Once user approves an overtime line for example: User approves overtime for employee name 'John' which starts on 7/1/2013 at 0400-0800, location is successfully added. When user tries to add location for John again which might has the start time for 7/1/2013 at 0600=0900. Again we are not entering Start time, End time and date it is already in the table. we are only entering location as approval. Soon user enters the location for John in the form field, since there is a conflict with previously overtime line which has already been approved. program needs to check employee name, date and time in previously approved (Added location) overtime line and The location in current record needs to be deleted and go to next record. I hope I have explained it in understandable format. Thank You,

  • Migrating an Access Database into SharePoint 2007.

    - by Mike T
    To my surprise and delight I read that an adminsitrator can import (nearly directly) an Access 2007 database into a sharepoint site. Automagically, the database in transformed into lists and views with some table lookup thrown in for good measure. With Access 2007 installed on the client machine, even the forms and what not can still be reused. To me... this sounds to good to be true. Has anyone actually dones this? With all this good news, where is the bad stuff and pitfalls to this. Depending on the size of the database, wouldn't this some how "gum up the works" in the SharPoint database? Sources: http://madhurahuja.blogspot.com/2007/01/adding-data-to-sharepoint-l-ists-in.html http://social.technet.microsoft.com/Forums/en-US/sharepointadmin/thread/17745835-a861-4984-9f44-7291fdae7d07

  • How do I show all group headers in Access 2007 reports?

    - by Newbie
    This is a question about Reports in Access 2007. I'm unsure whether the solution will involve any programming, but hopefully someone will be able to help me. I have a report which lists all records from a particular table (call it A), and groups them by their associated record in a related table (call it B). I use the 'group headers' to add the information from table-B into the report. The problem occurs when I filter the records from table-A that are shown in the report. If I filter out all table-A records that relate to a particular record (call it X) in table-B, the report no longer shows the record-X group header. As a possible workaround, I have tried to ensure that I have one empty record in table-A for each of the records in table-B. That way I can specify NOT to filter out these empty records. However, the outcome is ugly one-record-high blank spaces at the start of each group in the report. Does anyone know of an alternative solution?

  • Docmd.TransferText question

    - by every_answer_gets_a_point
    b'h i will be programmatically importing a text file into a table. i have saved the import steps. i will use this: DoCmd.TransferText(TransferType, SpecificationName, TableName, FileName, HasFieldNames, HTMLTableName, CodePage) to do the import. this is what SpecificationName means: Specification Name The specification name for the set of options that determines how a text file is imported, exported, or linked. For a fixed-width text file, you must either specify a specification name or use a schema.ini file, which should be stored in the same directory as the imported, linked, or exported text file. i do need a specific specification; however i do not know how to specify one. when i manually imported a table, i did save the specifications for my import, however i do not know how to call this in the TransferText. does anyone know how to specify SpecificationName ?

  • Update query (access & vb.net)

    - by yae
    Hi: I have to update some fields of a table of access according to the value of parameter. If this paramter is "true" I need to update. Table idInvoice price percentageTax1 tax1 percentageTax2 tax2 total Example values: idinvoice: 12300 price: 100 € percentageTax1: 10 % tax1= 10€ percentageTax2: 5 % tax2: 5€ total: 115 € (result: 100€+10€+5€) Ok. If the parameter on that I have commented before is "true" I must update the percentages and then update the total. I need to replace the "old" percentages by new percent. Ok I can do it in 3 queries: update invocies set percentageTax1=20,tax1=price *(percentageTax1/100) where idInvoice=@number and percentageTax1=10 update invocies set percentageTax2=7,tax2=price *(percentageTax2/100) where idInvoice=@number and percentageTax2=5 update invocies set total=price+tax1+tax2 where idInvoice=@number . But my question is: is there any an alternative to do this in 1 query?

  • Using unixODBC to connect to Oracle server

    - by Paul
    I am trying to configure our web server (RHEL 5.4 x86) to connect to an Oracle database using unixODBC. I have installed unixODBC-2.2.11-7.1.1, which yum tells me is the latest version. I have also installed the Oracle InstantClient 11.2 and the Oracle InstantClient ODBC library. I have symlinked the all the .so files in /usr/lib/oracle/11.2/client/lib to /usr/lib. I have set $LD_LIBRARY_PATH to /usr/lib/, $ORACLE_HOME to /usr/lib/oracle and $TNS_ADMIN to the directory containing my (valid) Tnsnames.ora file. Here are the contents of my /etc/odbcinst.ini file: [Oracle] Description = Oracle ODBC Connection Driver = /usr/lib/libsqora.so.11.1 Setup = FileUsage = and my /etc/odbc.ini file: [Oracle] Application Attributes = T Attributes = W BatchAutocommitMode = IfAllSuccessful CloseCursor = F DisableDPM = F DisableMTS = T Driver = Oracle EXECSchemaOpt = EXECSyntax = T Failover = T FailoverDelay = 10 FailoverRetryCount = 10 FetchBufferSize = 64000 ForceWCHAR = F Lobs = T Longs = T MetadataIdDefault = F QueryTimeout = T ResultSets = T ServerName = //<host>:<port>/<db> SQLGetData extensions = F Translation DLL = Translation Option = 0 UserID = (ServerName has been edited...host, port, and db are actually there, and correct) When I run isql I get $ isql -v Oracle isql: symbol lookup error: /usr/lib/libsqora.so.11.1: undefined symbol: SQLGetPrivateProfileStringW And running dltest gives me $ dltest Oracle SQLConnect [dltest] ERROR dlopen: Oracle: cannot open shared object file: No such file or directory If anyone has any insights I would be grateful, I've been trying to get this to connect for about 5 hours now...

  • How to troubleshoot web server lock-up (Debian Squeeze)

    - by Ryan
    Every once in a while, my web server slows so significantly, it seems locked up. Can't SSH in, no sites being served. It's a VPS that started out as Debian 5 which I upgraded to testing (squeeze). It's a typical LAMP set-up with the sole purpose of running a couple of wordpress sites. One time when it locked up, I got to one of the sites, but it was wordpress complaining it couldn't establish a database connection. So it seemed as if something was really chewing up the CPU and mysqld either timed out, or possibly failed and couldn't restart. But since I couldn't SSH in I feel more inclined to attribute it to CPU. But the only processes running now, aside from OS and kernel stuff: apache mysqld python (for fail2ban) sshd exim4 It has 512M of RAM and 1.5 GB of swap. Every time I check on it, it has plenty of free memory and is using virtually no swap (usually 2-3M). And since I am running fail2ban I don't think I'm getting ddosed. I did find this in my logwatch email this morning (it locked up late last night, when there would have been very little traffic): 6 Time(s): [<ffffffff810a0ebc>] ? oom_kill_process+0x7e/0x23d 6 Time(s): [<ffffffff810a1505>] ? __out_of_memory+0x12a/0x141 6 Time(s): [<ffffffff810a1586>] ? out_of_memory+0x6a/0x94 I didn't find anything else suspicious. It can't be my provider's host because I can SSH in and restart the VM, and everything seems fine. Anybody know which logs I should start poring through to find the core of my problem? Thanks guys.

  • Problems migrating software RAID 5 to new server (linux)

    - by leleu
    I have a CentOS setup with sw RAID5 that holds my data. Well, the server died, so I bought another box to migrate my drives to. Only thing is, I cannot get the RAID array rebuilt (not even sure it needs rebuilding, might just need the /dev/md0 mapping created... but I don't even know how to determine what I need!) Some details: RAID5 software (used mdadm) 4x 250GB drives (2 are SATA, 2 are EIDE -- would this matter? It worked fine in the other box...) latest CentOS distro built using mdadm I've got a decent amount of experience with standard linux stuff, but the hardware level stuff runs me in circles. I've spent some time googling and elsewhere here on SF, so please be kind for my newbie questions :). My question is this: how can I diagnose the problem? For all I know, I'm using the wrong device blocks when I try to rebuild the array, but I can't find the command to display only the devices that have some physical attachment. Is there some simple way for me to run mdadm, having it scan over all my physical drives, and say "hey, drives 2,5,6,7 are a software array, want me to mount it?" I basically just took the drives from my old box and put it into my new one. They show up in the BIOS. What steps do I need to take in order to get the array up, running, and mounted? Thanks in advance!
