  • Make cloudera-vm work on Oracle VM VirtualBox

    - by ????? ????????
    I downloaded this and the instructions say: Important: You must enable the I/O APIC in order to use 64-bit mode. (See http://www.virtualbox.org/manual/ch03.html.) On newer versions of VirtualBox, it may default to using SATA as the disk interface. This can cause a kernel panic in the VM. Switching to the IDE driver solves this problem. I am running this on Red Hat 64-bit mode (I've also tried on Ubuntu 64-bit with the same result). I pointed to the cloudera-vm image as a startup disk for the VM. I am getting this message: Failed to open a session for the virtual machine ClouderaDevelopment. VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED). Result Code: E_FAIL (0x80004005) Component: Console Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} Does anyone know what I am doing wrong?

  • Problem with ColdFusion communicating with MySQL database

    - by Greg
    Hi, I have been working to migrate a non-profit website from a local server (running Windows XP) to a GoDaddy hosting account (running Linux). Most of the pages are written in ColdFusion. Things have gone smoothly, up until this point. There is a flash form within the site (see this page: http://www.preservenet.cornell.edu/employ/submitjob.cfm) which, when completed, takes the visitor to this page: submitjobaction.cfm . I'm not quite sure what to make of this error, since I copied exactly what had been in the old MySQL database, and the .cfm files are exactly as they had been when they worked on the old server. Am I missing something? Below is the code from the database that the error seems to be referring to. When I change "Positionlat" to some default value in the database as it suggests in the error, it says that another field needs a default value, and it's a neverending chain of errors as I try to correct it. This is probably a stupid error that I'm missing, but I've been working at it for days and can't find what I'm missing. I would really appreciate any help. Thanks! -Greg DROP TABLE IF EXISTS employopp; CREATE TABLE employopp ( POSTID int(10) NOT NULL auto_increment, USERID varchar(10) collate latin1_general_ci default NULL, STATUS varchar(10) collate latin1_general_ci NOT NULL default 'ACTIVE', TYPE varchar(50) collate latin1_general_ci default 'professional', JOBTITLE varchar(70) collate latin1_general_ci default NULL, NUMBER varchar(30) collate latin1_general_ci default NULL, SALARY varchar(40) collate latin1_general_ci default NULL, ORGNAME varchar(70) collate latin1_general_ci default NULL, DEPTNAME varchar(70) collate latin1_general_ci default NULL, ORGDETAILS mediumtext character set utf8 collate utf8_unicode_ci, ORGWEBSITE varchar(200) collate latin1_general_ci default NULL, ADDRESS varchar(60) collate latin1_general_ci default 'none given', ADDRESS2 varchar(60) collate latin1_general_ci default NULL, CITY varchar(30) collate latin1_general_ci default NULL, STATE varchar(30) collate latin1_general_ci default NULL, COUNTRY varchar(3) collate latin1_general_ci default 'USA', POSTALCODE varchar(10) collate latin1_general_ci default NULL, EMAIL varchar(75) collate latin1_general_ci default NULL, NOMAIL varchar(5) collate latin1_general_ci default NULL, PHONE varchar(20) collate latin1_general_ci default NULL, FAX varchar(20) collate latin1_general_ci default NULL, WEBSITE varchar(200) collate latin1_general_ci default NULL, POSTDATE varchar(10) collate latin1_general_ci default NULL, POSTUNTIL varchar(20) collate latin1_general_ci default 'select date', POSTUNTILFILLED varchar(20) collate latin1_general_ci NOT NULL default 'until filled', texteHTML mediumtext character set utf8 collate utf8_unicode_ci, HOWTOAPPLY mediumtext character set utf8 collate utf8_unicode_ci, CONFIRSTNM varchar(30) collate latin1_general_ci default NULL, CONLASTNM varchar(60) collate latin1_general_ci default NULL, POSITIONCITY varchar(30) collate latin1_general_ci default NULL, POSITIONSTATE varchar(30) collate latin1_general_ci default NULL, POSITIONCOUNTRY varchar(3) collate latin1_general_ci default 'USA', POSITIONLAT varchar(50) collate latin1_general_ci NOT NULL, POSITIONLNG varchar(50) collate latin1_general_ci NOT NULL, PRIMARY KEY (POSTID) ) ENGINE=MyISAM AUTO_INCREMENT=2007 DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci;

  • Oracle Apex:Why is this dynamic action not getting triggered/fired ?

    - by Sathya
    I'm using Application Express 4.0.0.00.25 ( Apex 4.0 EA2 ). I've created a tabular form, with few fields. Each of the field are not direct entry, but rather a LOV picker is attached to these, and on selecting the LOV value, the id gets stored in the field. I have a dynamic action associated to the field, ( event - change in item, condition - always, action - Set value via SQL query ). However, on selecting the value from the LOV, the dynamic action doesn't get triggered. If I select the dynamic action to be fired on page load, then it works but not upon selection of an item from the LOV. Why is this so, is it by design or a bug ?

  • Oracle SQLPlus: How to display the output of a sqlplus command without having to first issue the spo

    - by ziggy
    Is there a way to display the output of a sqlplus command without having to first issue the spool off command? I am spooling the results of a sqlplus session to a file while at the same time tailing the file. The reason for this is that for table with very long rows the format is easier to look at from a file. The problem is to see the output i have to issue the spool off command everytime i run a command in sqlplus. Can i configure sqlplus so that after i have issued the spool command all the output is viewable straight away on the file. (Formating the way the rows are displayed on the screen is not an option. ) THanks

    Hello everybody, is there a good example of the late binding features of the LinFu framework? I developed a framework which is hard linked against a certain version of an Oracle client. Now I would like to be able to configure the version of the client without the need to rebuild the app. How can I do that with LinFu? Regards, Alex

  • How to recreate missing Team Foundation Server database?

    - by Amadiere
    I've been trying out TFS 2010 Beta 2 on my local machine, or at least, had installed ready to do so. I had some issues with my MSSQL2008 server so I completely uninstalled and re-installed it and that sorted it. However, I'm now in limbo with TFS. I have the software installed, but it has none of the SQL databases installed that go with it. I had no data and am not precious about how to go about it. I figure completely uninstalling and re-installing might be an idea and will most likely fix it (repair didn't work). Is there a quicker way? Is there a command line utility that I can run, or a SQL script to recreate it all?

  • How to restore PostgreSQL database from .tar file?

    - by Stephen
    I have all PostgreSQL databases backed up during incremental backups using WHM, which creates a $dbName.tar file. Data is stored in these .tar files, but I do not know how to restore it back into the individual databases via SSH. In particular the file location. I have been using: pg_restore -d client03 /backup/cpbackup/daily/client03/psql/client03.tar which generates the error 'could not open input file: Permission denied' Any assistance appreciated.

  • How do you find the disk size of a Postgres table and its indexes

    - by mmrobins
    I'm coming to Postgres from Oracle and looking for a way to find the table and index size in terms of bytes/MB/GB/etc, or even better the size for all tables. In Oracle I had a nasty long query that looked at user_lobs and user_segments to give back an answer. I assume in Postgres there's something I can use in the information_schema tables, but I'm not seeing where. Thanks in advance.

  • Oracle java 6 on ubuntu

    - by Shanee
    The java library I need (jpcap) only works on java 6, it won't work with java 7 (and I have tried :( ), is it still possible to install java 6 on ubuntu? Only according to https://help.ubuntu.com/community/Java#Choosing_the_default_Java_to_use, 'Oracle (Sun) Java 6 is no longer available to be distributed by Ubuntu, because of license issues' I've tried to use the instructions on the same site but they don't seem to work... "./jre-6u34-linux-i586.bin" doesn't seem to do anything! Thanks!

  • database security with php page that spits out XML

    - by Rees
    Hello, I just created a PHP page that spits outs some data from my database in an XML format. This data is fetched from a flex application I made. I had spent a long time formatting my tables and database information and do not want anyone to be able to simply type www.mysite.com/page_that_spits_out_XML.php and steal my data. However, at the same time I need to be able to access this page from my flex application. Is there a way I can prevent other people from doing this? Thank you!

  • Normalization in plain English

    - by Yada
    I sort of understand the concept of database normalization but always have a hard time explaining it in plain English especially for a job interview. I have read the wikipedia post, but still find it hard to explain the concept to none developers. "Design a database in a way not to get duplicated data" is the first thing that comes to mind. Does anyone was a nice way to explain the concept of database normalization in plain English. And what are some nice examples to show the differences between first, second and third normal forms. Say you go to a job interview and the person asks: Explain the concept of normalization and how would go about designing a normalized database. What key points are the interviewer looking for?

  • Storing date and time as epoch vs native datetime format in the database

    - by zakovyrya
    For most of my tasks I find it much easier to work with date and time in the epoch format: it's trivial to calculate timespan or determine if some event happened before or after another, I don't have to deal with time-zone issues if the data comes from different geographical sources, in case of scripting languages what I usually get from database when I request a datetime-typed column is a string that I need to parse in order to work with it. This list can go on, but for me in order to keep my code portable that's enough to ditch database's native datetime format and store date and time as integer. What do you guys think?

  • mySQL removes first digit

    - by kielie
    Hi guys, I am inputting data into a mySQL database via a PHP script, but for some reason when I check the database, all of the phone numbers have their first digit removed, like so, 0123456789 shows up as 123456789 in the database, but if I change the data type from INT to TEXT, it shows correctly, I am very hesitant to keep it as TEXT though, as I am sure this will cause complications further down the road as the database app starts to become more complicated, here is the PHP code. <?php $gender = $_POST['gender']; $first_name = $_POST['first_name']; $second_name = $_POST['second_name']; $id_number = $_POST['id_number']; $home_number = $_POST['home_number']; $cell_work = $_POST['cell_work']; $email_address = $_POST['email_address']; $curDate = date("Y-m-d"); mysql_connect ("server", "user", "pass") or die ('Error: ' . mysql_error()); mysql_select_db ("database"); $query = "INSERT INTO table (id,gender,first_name,second_name,id_number,home_number,cell_work,email_address,date) VALUES('NULL','".$gender."','".$first_name."','".$second_name."','".$id_number."','".$home_number."','".$cell_work."','".$email_address."','".$curDate."' )"; mysql_query($query) or die (mysql_error()); ?> Thanx in advance!

  • How to prevent column b containing the same value as any column a in Oracle?

    - by Janek Bogucki
    What is a good way to prevent a table with 2 columns, a and b, from having any record where column b is equal to any value in column a? This would be used for a table of corrections like this, MR -> Mr Prf. -> Prof. MRs -> Mrs I can see how it could be done with a trigger and a subquery assuming no concurrent activity but a more declarative approach would be preferable. This is an example of what should be prevented, Wing Commdr. -> Wing Cdr. Wing Cdr. -> Wing Commander Ideally the solution would work with concurrent inserts and updates.

  • Calculation with RESTful web service with MySQL database

    - by Dobby
    I am now making some RESTful web services with MySQL database. I used NetBeans to create the resources of RESTful service with MySQL, and now I can now use GET and POST/PUT to list and add/modify data entities in the MySQL server. Currently, I wish to make some calculations right after a client makes the POST activities, then the posted data with calculated results will be inserted into the MySQL database. I am very new to this, I guess I need to add some functions and call them to calculate but I don't know where and how to do that : ( Could any one help me on this issue? Thanks a lot in advance! : )

  • PostGIS - can't create spatially-enabled database

    - by itgorilla
    I'm using Ubuntu 10.10, PostgreSQL 9.0 and PostGIS 1.5. I've installed PostGIS 1.5 from: https://launchpad.net/~ubuntugis/+archive/ubuntugis-unstable I used PPA first then the command: sudo apt-get install postgis to install postgis. I've been following these instructions to create a spatially-enabled database: http://ostgis.refractions.net/docs/ch02.html#id2630100 I got to the point where it's saying: Now load the PostGIS object and function definitions into your database by loading the postgis.sql definitions file (located in [prefix]/share/contrib as specified during the configuration step). psql -d [yourdatabase] -f postgis.sql Well, there is no postgis.sql on my server after the installation. I did an sudo updatedb to make sure I can find postgis.sql but it's not there. Any ideas? Thank you!

  • Restoring database with SMO - Reporting progress problems

    I'm using the below to restore a database in VB.NET. This works but causes the interface to lockup if the user clicks anything. Also, I cannot get the progress label to update incrementally, it's blank until the backup is complete then displays 100% Sub DoRestore() Dim svr As Server = New Server("Server\SQL2008") Dim res As Restore = New Restore() res.Devices.AddDevice("C:\MyDB.bak", DeviceType.File) res.Database = "MyDB" res.RelocateFiles.Add(New RelocateFile("MyDB_Data", "C:\MyDB.mdf")) res.RelocateFiles.Add(New RelocateFile("MyDB_Log", "C:\MyDB.ldf")) res.PercentCompleteNotification = 1 AddHandler res.PercentComplete, AddressOf ProgressEventHandler res.SqlRestore(svr) End Sub Private Sub ProgressEventHandler(ByVal sender As Object, ByVal e As PercentCompleteEventArgs) Label3.Text = "" ProgressBar.Value = e.Percent LblProgress.Text = e.Percent.ToString End Sub

  • LDAP: Extend database using referral

    - by ecapstone
    My company uses an off-site LDAP server to handle authentication. I'm currently working on a local VPN for my branch that needs to use the off-site LDAP to check user's usernames and passwords, but I don't want every employee to have access to the VPN - I need to be able to control whether users can authenticate with the off-site LDAP based on whether they're allowed to use the VPN. My current solution involves having our own local LDAP server, which has a referral to the off-site server (I got most of my information from here: http://www.zytrax.com/books/ldap/ch7/referrals.html). This means that when local users try to check their credentials with the local server, it redirects them to the off-site server, which checks the credentials. This works for authentication, but not for authorization. It would be easiest to add a vpn_users group or is_vpn_user attribute on the off-site server, but, well, that's above my pay grade. Is there any way I can use the local server to control whether users have access to the VPN without needing to change the off-site server? If I could somehow use it to have a local vpn_users group without the users in it having to be located on the local server, that would probably work, but I have no idea how to set that up or if LDAP even supports such a configuration. For reference, I'm using the openvpn-auth-ldap (https://code.google.com/p/openvpn-auth-ldap/) plugin.

  • Are database triggers evil?

    - by WW
    Are database triggers a bad idea? In my experience they are evil, because they can result in surprising side effects, and are difficult to debug (especially when one trigger fires another). Often developers do not even think of looking if there is a trigger. On the other hand, it seems like if you have logic that must occur evertime a new FOO is created in the database then the most foolproof place to put it is an insert trigger on the FOO table. The only time we're using triggers is for really simple things like setting the ModifiedDate.

  • Oracle Merge Rejection Row Count

    - by Andrew
    Given an Oracle Merge statement with a rejection limit, is there a shorthand way to identify how many rows were rejected, without being forced to query the rejection destination? The rejection destination has records pre-merge, so would currently have to be counted twice and the difference taken, but it seems like there should be a counter exposed, given that it has to be aware of whether it has exceeded the rejection limit.

  • Oracle: Insertion on an indexed table, avoiding duplicates. Looking for tips and advice.

    - by Tom
    Hi everyone, Im looking for the best solution (performance wise) to achieve this. I have to insert records into a table, avoiding duplicates. For example, take table A Insert into A ( Select DISTINCT [FIELDS] from B,C,D.. WHERE (JOIN CONDITIONS ON B,C,D..) AND NOT EXISTS ( SELECT * FROM A ATMP WHERE ATMP.SOMEKEY = A.SOMEKEY ) ); I have an index over A.SOMEKEY, just to optimize the NOT EXISTS query, but i realize that inserting on an indexed table will be a performance hit. So I was thinking of duplicating Table A in a Global Temporary Table, where I would keep the index. Then, removing the index from Table A and executing the query, but modified Insert into A ( Select DISTINCT [FIELDS] from B,C,D.. WHERE (JOIN CONDITIONS ON B,C,D..) AND NOT EXISTS ( SELECT * FROM GLOBAL_TEMPORARY_TABLE_A ATMP WHERE ATMP.SOMEKEY = A.SOMEKEY ) ); This would solve the "inserting on an index table", but I would have to update the Global Temporary A with each insertion I make. I'm kind of lost here, Is there a better way to achieve this? Thanks in advance,
