  • MS Access questions - Scalability / indexing / transactions

    - by oo
    A few questions on MS Access databases - Size: Are there limits to the size of an access database? The reason i ask is that we have an access database that has a few simple tables. The size of the db is about 1GB. When I do a query on it, i see it taking over 10 minutes to run. With proper indexing, should MS Access be able to handle this or are there fundamental limitations to the technology. This is MS Access XP. Also, does MS Access support db transactions, commit and rollback?

  • Weird Apache Access Logs

    - by user38480
    I see repeated requests like these in my Apache Access Logs and they have been eating up all my CPU. I have a normal WordPress installation. All i changed in the Apache Configuration was changing the DocumentRoot from /var/www/html to /var/www for both ssl and the default configuration. Also, the file referenced in the requests(updatedll.jpeg) does not exist on my server and also isn't referenced in the source code served by any page of the web application. Could this be a security threat? What are these actually and what can i do to stop them. I changed the ip address of my server. They still kept coming. Meaning that somebody is actually hitting the domain name and not the ip address. Why does my server send a 301 for these requests? Shouldn't it be sending a 404? Is it because Wordpress is installed in my root directory and the .htaccess file present for Wordpress is sending a 301 redirect? My disk access logs also seem to have high peaks intermittently. But nobody is actually accessing the site. I see no access logs except these below. Also, i see that all the requests seem to be coming from one of the following 5 ip addresses. 201.4.132.43 - - [05/Jun/2014:07:35:08 -0400] "GET /updatedll.jpg HTTP/1.1" 301 465 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/4.0; BTRS103681; GTB7.5; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; InfoPath.2; OfficeLiveConnector.1.3; OfficeLivePatch.0.0; AskTbATU3/5.15.29.67612; BRI/2)" 187.40.241.48 - - [05/Jun/2014:07:35:08 -0400] "GET /updatedll.jpg HTTP/1.1" 301 465 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; GTB7.5; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)" 186.56.134.132 - - [05/Jun/2014:07:35:10 -0400] "GET /updatedll.jpg HTTP/1.0" 301 428 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)" 71.223.252.14 - - [05/Jun/2014:07:35:13 -0400] "GET /updatedll.jpg HTTP/1.1" 301 465 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; BTRS31756; GTB7.5; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET4.0C; .NET4.0E; InfoPath.2)" 85.245.229.167 - - [05/Jun/2014:07:35:14 -0400] "GET /updatedll.jpg HTTP/1.1" 301 465 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; MAAU; .NET4.0C; BRI/2; .NET4.0E; MAAU)"

    string createTable = "CREATE TABLE IF NOT EXISTS " + m_strDatabase + "_TimeLogs (logName VARCHAR(16), logTime INTEGER, logCountry TEXT, UNIQUE(logName)) TYPE=MyISAM;"; When this runs, no table is created. No errors either. Im using an ODBC connector. the variable passes in the db name, so that the table created would be users_TimeLogs if the database was called users for example. Am I doing something wrong?

  • Remotely managing Scheduled Tasks on another computer: Access Denied

    - by Eptin
    I need to remotely create new scheduled tasks from a Windows 7 computer in my company (which according to this Microsoft TechNet article I should be able to do. http://technet.microsoft.com/en-us/library/cc766266.aspx ) From within Task Scheduler, on the menu I click Action Connect to another Computer. I browse for the remote computer's name (I use Check Names to verify that the name is correct) and then I check 'Connect as another user' and enter \Administrator and the local admin password. Whenever I try this, I get the error message Task Scheduler: You do not have permission to access this computer Firewall isn't the problem I am able to use Remote Desktop with this username & password combo, so I would expect it to work when remotely managing as well. The remote computer has firewall exceptions for Remote Scheduled Tasks Management, Remote Service Management, and Remote Desktop among other things. Heck, I even tried turning off the firewall for that individual computer and it still didn't work. More details: I have administrative remote access to several other Windows 7 Enterprise computers, though I log in as the local Administrator (whose administrative rights are only recognized by that local machine, not by the domain). The computer I am managing from is on the domain, and also has administrative rights that are recognized on the domain. More experimentation: If I go the other way around and remote-desktop into the other machine and from there open task scheduler then 'connect to another computer', I am able to connect back to my main computer using the username & password that is recognized by an administrator on the domain, and successfully schedule a task on my main computer. So it's not a company firewall issue that's preventing anything from working. The only permissions requirement Microsoft talks about is "The user credentials that you use to connect to the remote computer must be a member of the Administrators group on the remote computer". I'm logging in as an Administrator on each of the local machines, so why doesn't it work?

  • Linksys WAP54G v3.1 no access, power and link LED solid

    - by user142113
    I'm managing the Network of a small enterprise. A Linksys WAP54G v3.1 used to provide the WiFi network. I was called, because the device did not provide a WiFi network anymore. I first of all tried to ping the device via LAN, but there was no reaction. I've frequently reconnected the AP to the mains and always the POWER and the LINK LED keep solid, even if no network cable is connected. What I've done yet: Reset as documented: Pressed the RESET button for 10 seconds. After that I have tried to access the AP with a direct cable connection to my computer, that I've set to a static ip of 192.168.1.240, but i got no ping response on the default IP 192.168.1.245. Furthermore ipconfig reports "media disconnected". More complex reset method as described here http://bruceshankle.blogspot.de/2005/12/how-to-reset-linksys-wap54g.html as well had no effect. also tried to ping 192.168.1.1 without success Tried this method: http://www.daniweb.com/hardware-and-software/networking/threads/142437/linksys-wireless-access-point-problem#post680245 but there was no ping response when powering up. As well the tftp transfer timed out Finally tried to short pin 15 and 16 of the flash chip on the bottom side of the AP mainboard while booting to provoke a Checksum error. This should lead to the possibility to upload a firmware with tftp, as the AP stops booting and waits for a tftp connection on 192.168.1.1. But I've had no success. As well i've put pin 15 and 16 to ground while booting, also without an effect. After all that I still can't ping the AP, ipconfig still tells me "media disconnected". The POWER and LINK LED are solid. I would appreciate your answers

  • Have local admin privileges on Windows XP, but getting "Error terminating process: Access is denied"

    - by Chris W. Rea
    On one of the Windows XP machines I use regularly, there is a process that starts up periodically. I'd like to be able to kill the process – sometimes – because it occasionally runs when I'm busy doing something machine-intensive. I've already tried dropping the process priority to "Idle" to mitigate the effects, but it isn't the CPU that's the problem. Rather, the process is very disk-intensive and no matter the process priority, it still causes significant disk thrashing when running, impacting everything else I'm doing at the time. Using Process Explorer, I can find the process, right-click, and choose Kill Process, but I always get the message "Error terminating process: Access is denied." This is not an operating system process, but third-party software. What might that process be doing to prevent itself from being terminated? How can I kill such a process? Is there a way for me to modify the process's security or access control list (ACL) somewhere, using Process Explorer or another tool, so that I can effectively kill it?

  • Interesting phenomenom with Windows Server 2008 R2 user access controls and NTFS ACLs

    - by Simon Catlin
    One to try, and I'd appreciate any thoughts on this. On a Windows Server 2008 R2 box (or presumably 2008 R1, Windows Vista or Windows 7): i) Logon as an administrator, and create a new NTFS volume ii) Blow away the standard MS ACLS on the root of the volume (which are laughable), and replace with Administrators:Full Control, System:Full Control, e.g.: echo Y|cacls.exe d:\ /g "Administrators:F" "SYSTEM:F" iii) Now, from a Command Prompt shell window or PowerShell window, switch to that drive (cd /d D:\ or set-location D:\ ). Works fine... no issues. iv) Now, try to browse to the root of the new volume using MS Explorer... Access denied. Now, I've kind of convinced myself that it is UAC getting in the way, as you can add "Authenticated Users:List" access to D:\ and Explorer then works. I can only assume that MS Explorer isn't able to use the "admin" token for the Administrator. Browsing to explorer.exe and doing a "Run as administrator" has no effect. Any thoughts? Cheers in advance.

  • Access 2010 datasheet view only/relationships unavailable

    - by Luis
    I'm relatively new to MS Access in general and just started working with Access 2010. I've created a new web database with a few tables that I need to relate. First problem: For the life of me, I can't view anything in any view other than datasheet view; everywhere I would expect to be able to change the view, only datasheet view is available. Second problem: I can't change the primary key(s). Presumably I would be able to do this if I could get out of datasheet view and into design view. Third problem: The 'Relationships' button is greyed out. I know these appear to be really simple things but I've been looking for much more time than I'd like to admit trying to figure out how to get unstuck. Update: It would appear that this is happening because it is a 'web database' as I've been able to do all of the above in a new regular database. With this in mind let me ask a different question: Am I able to add relationships and change primary keys in a web database? If so how? More generally, what is the point of a web database?

  • customer wont provide ssh access - ftp only

    - by Max
    Eh, here is my problem: I am working in a webdevelopment agency (thats a problem but not the real problem, read on). Most of the time I choose the live server myself when creating a new website project. But now the customer already has a "server" (10 GB on a cheapo host!) and the "admin" refuses to give me ssh access to it. But I need to access the server via shell because many files will be transported (need to be able to upload and extract a tar) and I need to insert or create mysql dumps via command line. He argues FTP and phpmyadmin should be enough... as far as I know the webspace was just ordered to host the website, so no security critical apps are running there. How can I either convince the admin to give me the ssh login or tell management that we need our own server? Anyone with similiar experiences? This is really annoying as this is a very small project that should be done fast and now one has to fight in order to just get the work done...

  • Can't access to access to my web server inside a network with Firewall on

    - by ianenri
    I set up a Web server with the following: There is the Internet Router, configured to Port Foward port 80 to my computer assigned to my PC's IP: 192.168.1.128 My PC is connected to that wireless router from wlan0 Then, my PC is also connected to my device (which is the webserver) with a crossover-cable usign eth0 having this anohter IP: 10.42.43.1 Finally, my device (the webserver) is connected with eth0 with this IP: 10.42.43.55 As you can see, I need to install a reverse-proxy to be able to resolve to my device's webserver. I installed pound (proxy server) in my PC and configured properly to make 192.168.1.128 resolve to 10.42.43.55 So, I just typing my ISP provided IP 200.x.x.x resolves to my device webserver. But there's a problem: I HAD TO STOP MY FIREWALL. I don't know how I need exactly configure the firewall in SUSE YAST2, or at least iptables. Stopping it is not an option, not for security reasons, just because there's port fowarding rule that is needed to give Internet access to my device too. I'm using openSUSE 12.1

  • Using Hibernate with MS ACCESS 2007 Database (Free JDBC Driver)

    - by Quentin T.
    1. I want to do a reverse engineering action with the Hibernate plugin of Eclipse on a MS Access 2007 Database. I'm forced to use a existing MS Access 2007 db. A easy solution is to buy the HXTT. But I want to use a free driver to do my work. So I tried to apply this post : http://www.programmingforfuture.com/2011/06/how-to-use-ms-access-with-hibernate.html (That uses the SQL Server dialect and the driver sun.jdbc.odbc.JdbcOdbcDriver) Unfortunately I have an error that nobody seems to have been on the internet: Exception while generating code Reason : org.hibernate.exception.GenericJDBCException: Error while reading primary key meta data for `c:/myaccessdb.mdb`.TableTest1 I have try to change the primary key on my MS Access DB (deleting all primary key) or to try the reverse engineering on a MS ACCESS with only one table without primary key, but I got all times the problems. 2. The purpose of my job is to transfer daily (weekly) an Oracle 11g database with data from an existing database MS ACCESS 2007. And I thought to use a procedure (Hibernate EJB) Java to be launched automatically every week to do the data transfer. Is this is the best solution ? Configuration : sun.jdbc.odbc.JdbcOdbcDriver v??? Hibernate v3.4 Eclipse ps: If you are a HXTT developer or seller please be indulgent with my post ;). Making money by making people believe that you help, it's bad ! A solution is to use Derby Client driver, as the solution in the post: Does anyone know if Hibernate and java will work effectively with Access? But a clarification of the answer of Rich Seller is required. Could you explain your answer and explain your configuration (hibernate.cfg.xml, persistence.xml and what URL you use in the property name="hibernate.connection.url") without using paying HXTT driver but with the free Derby driver.

  • MYSQL stored function - create function (function definition) problem using FORMAT

    - by Jason Fonseca
    Hi all, I keep receiving an error with the following code. I am trying to make a function that will format a field (content=0.0032) into a varchar/percent (content=0.32%). At the moment i'm just trying to get format to work, and it throws up an error "Error Code : 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'len);" The function definition for "Format" is "Format(X,d)" where x is the number and d is the number of decimal places to round too. It then should output a string ###,###,###.## etc. My code is as follows: DROP FUNCTION IF EXISTS percent; DELIMITER $$ CREATE /*[DEFINER = { user | CURRENT_USER }]*/ FUNCTION `auau7859_aba`.`percent`(num DOUBLE, len INT) RETURNS VARCHAR(10) DETERMINISTIC BEGIN RETURN FORMAT(num,len); END$$ DELIMITER ; Save me...Luke

  • How to enable/create elements on the fly

    - by Simon S
    Hi all I am using a combination of PHP, jQuery and Spry to serve a series of listboxes in which a user will select first the type of vehicle, then the make, then the model and finally the specific model. All my listboxes (SELECT) are working fine, and they update properly using the Spry elements. Each listbox is populated from a different Spry XML Dataset, and this is my problem. If I present all four listboxes to the user, the script has to go and fetch all four lots of XML to populate all four listboxes, taking several seconds. What I want to do is to create/enable the listboxes in order, so at the user selects from the first listbox, the second is created/enabled, when they select from the second, the third is created/enabled... and so on. Setting the disabled attribute is no good because the script has already fetched the XML before this is processed. Any ideas?? Si

  • create a folder and files in c:\program files\myApp\data in windows 7

    - by ile
    I have an old c++ application that needs to be modified to work with windows 7. Problem is in creating a new folder and saving a file in that folder. This folder should be created in c:\program files\myApp\data\newFolder. This is function I use to create new folder and get errors: if(!CreateDirectory(pathSamples,NULL)) //Throw Error { DWORD errorcode = GetLastError(); LPVOID lpMsgBuf; FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, errorcode, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR)&lpMsgBuf, 0, NULL ); MessageBox(NULL, (LPCTSTR)lpMsgBuf, TEXT("Error"), MB_OK); } In XP this works, but in Windows 7 it doesn't. If I run application as administrator than the folder is created, otherwise "Access is denied" error is thrown. My question is following: Is there an option to make changes to the code so that the folder can be created in "program files" nad that files can be saved in this folder? PS I saw this thread already but it doesn't answer my question. Thanks, Ilija
