• Exchange emails not delivering for one user

  - by Cylindric

  We have an Exchange infrastructure going through a migration from 2003 SP2 (call it ExOld) to 2010 (ExNew). All users are now on the new server, but mail is still being directed to ExOld until testing is complete. ExNew sends emails directly to the internet. For one particular user, emails don't seem to be being reliably delivered, but the odd thing is that it's not all emails. I can see external emails in his inbox. If I send an internal email it works fine. If I send an email from Gmail to him it doesn't get through. If I telnet from outside to ExOld I can send an email to him. If I telnet from outside to ExNew I can send an email to him. This is a transcript that results in a successful send: 220 ExOldName Microsoft ESMTP MAIL Service, Version: 6.0.3790.4675 ready at Mon, 22 Oct 2012 10:55:26 +0100 EHLO test.com 500 5.3.3 Unrecognized command EHLO test.com 250-ExOldFQDN Hello [MyTestExternalIp] 250-TURN 250-SIZE 250-ETRN 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-8bitmime 250-BINARYMIME 250-CHUNKING 250-VRFY 250-X-EXPS GSSAPI NTLM LOGIN 250-X-EXPS=LOGIN 250-AUTH GSSAPI NTLM LOGIN 250-AUTH=LOGIN 250-X-LINK2STATE 250-XEXCH50 250 OK MAIL FROM:[email protected] 250 2.1.0 [email protected] OK RCPT TO:[email protected] notify=success,failure 250 2.1.5 [email protected] DATA 354 Start mail input; end with .

• Low overhead Java Web Services container?

  - by trojanfoe

  I want to provide a Java-based Web Service, but I don't require the features of a full-blown J2EE Application Server. I would like it to start as quickly as possible, though that's not a hard requirement. The Web Service will handle multiple connections and require access to an Oracle database so it will at least require a thread pool and database connection pool. I may want to put a JSP interface onto it later to provide an internal maintainence interface. I have looked at Jetty with an Apache CXF stack, but it looks like I'll have to do a fair amount configuration before even coding the web service - Will it be worth it? Will it even work? Should I forget about the complexity and simply go with JBoss/Weblogic/etc and put up with the bloat and extra start-up time?

• entity framework and dirty reads

  - by bryanjonker

  I have Entity Framework (.NET 4.0) going against SQL Server 2008. The database is (theoretically) getting updated during business hours -- delete, then insert, all through a transaction. Practically, it's not going to happen that often. But, I need to make sure I can always read data in the database. The application I'm writing will never do any types of writes to the data -- read-only. If I do a dirty read, I can always access the data; the worst that happens is I get old data (which is acceptable). However, can I tell Entity Framework to always use dirty reads? Are there performance or data integrity issues I need to worry about if I set up EF this way? Or should I take a step back and see about rewriting the process that's doing the delete/insert process?

• Can you hide tables from a MySQL user in phpMyAdmin?

  - by AK

  I have a MySQL user added to a database that I would like to prevent from viewing certain tables. I can limit their privileges through MySQL by preventing them from running statements like DROP or ALTER. But is it possible to prevent them from viewing certain tables in phpMyAdmin? If there isn't a MySQL privilege that controls this (I wouldn't imagine there would be), is there a configuration in phpMyAdmin that allows this? I understand one workaround here is to move the tables to a new database that they're not added to. This isn't an option for my application.

• Read Call History from iPhone on iOS 5 and above

  - by Sandeep Dhama

  I am developing an application and need to read the users call history from iPhone.I have go though all the forums and google it and found that we can get the records from teh callHistory sqlite database by "private/var/root/Library/CallHistory/call_history.db". But this path is not working from iOS 5 and above. Seems like apple has changed all their database path and structure so that no one can accees it. I have also seen some of the application on iTunes who are capable of getting the users call history like:-https://itunes.apple.com/us/app/callog/id327883585?mt=8 I have also check a mac desktop utility called "WonderShare Dr.Fone" which will fetch all the data from your iPhone like call history messages, notes , etc.How this utility is fetching the call history records and other details? If their is any API or private APIs by which i can get the callHistory data path please let me know.

• building objects from xml file at runtime and intializing, in one pass?

  - by KaluSingh Gabbar

  I have to parse the XML file and build objects representation based on that, now once I get all these data I create entries in various database for these data objects. I have to do second pass over that for value as in the first pass all I could do is build the assets in various databases. and in second pass I get the values for all the data and put it in the database. I have a feeling that this can be done in a single pass but I just want to see what are your opinions. As I am just a student who started with professional work, experienced ppl please help. Can someone who have ideas or done similar work, please provide some light on the topic so that I can think over the possibility of the work and get the prototype going based on your suggestion. Thanks a lot for your precious time, I honestly appreciate it.

• How to convert full outer join query to O-R query?

  - by Kugel

  I'm converting relational database into object-relational in Oracle. I have a query that uses full outer join in the old one. Is it possible to write the same query for O-R database without explicitly using full outer join? For normal inner join it simple, I just use dot notation together with ref/deref. I'm interested in this in general so let's say the relational query is: select a.attr, b.attr from a full outer join b on (a.fk = b.pk); I want to know if it's a good idea to do it this way: select a.attr, b.attr from a_obj a full outer join b_obj b on (a.b_ref = ref(b));

• How to use Zend_Cache Identifier ?

  - by ArneRie

  Hi Folks, i think iam getting crazy, iam trying to implement Zend_Cache to cache my database query. I know how it works and how to configure. But i cant find a good way to set the Identifier for the cache entrys. I have an method wich search for records in my database (based on an array with search values). /** * Find Record(s) * Returns one record, or array with objects * * @param array $search Search columns => value * @param integer $limit Limit results * @return array One record , or array with objects */ public function find(array $search, $limit = null) { $identifier = 'NoIdea'; if (!($data = $this->_cache->load($identifier))) { // fetch // save to cache with $identifier.. } But what kind of identifier can use in this situation?

• Huge page buffer vs. multiple simultaneous processes

  - by Andrei K.

  One of our customer has a 35 Gb database with average active connections count about 70-80. Some tables in database have more than 10M records per table. Now they have bought new server: 4 * 6 Core = 24 Cores CPU, 48 Gb RAM, 2 RAID controllers 256 Mb cache, with 8 SAS 15K HDD on each. 64bit OS. I'm wondering, what would be a fastest configuration: 1) FB 2.5 SuperServer with huge buffer 8192 * 3500000 pages = 29 Gb or 2) FB 2.5 Classic with small buffer of 1000 pages. Maybe some one has tested such case before and will save me days of work :) Thanks in advance.

• Using multiple databases within one application

  - by Alex

  I have a web application made for several groups of people not connected with each other. Instead of using one database for all of them, I'm thinking about making separate databases. This will improve the speed of the queries and make me free from checking to what group the user belongs. But since I'm working with LINQ to SQL, my classes are explicitly connected with the databases, so I will have to make separate DataContexts for all of the databases. So how can I solve this problem? Or should I just not bother and use one database only?

• SQLite SQLite column can't be updated to any value but zero (real type)

  - by user1065320

  Hi I'm trying to create a three fields table (date,text,real), I can insert and update the first two fields but can't set or update the last one. createSQL = @"CREATE TABLE IF NOT EXISTS ACTIVITIES (MYDATE DATETIME PRIMARY KEY, ACTIVITY TEXT , LENGTH REAL);"; try to insert char *update = "INSERT OR REPLACE INTO ACTIVITIES (MYDATE, ACTIVITY , LENGTH) VALUES (?, ? ,?);"; sqlite3_stmt *stmt; if (sqlite3_prepare_v2(database, update , -1, &stmt, nil) == SQLITE_OK) { sqlite3_bind_double(stmt, 1, valueToWrite); sqlite3_bind_text(stmt, 2, [task UTF8String], -1, NULL); sqlite3_bind_double(stmt, 3, 1.5); } if (sqlite3_step(stmt) != SQLITE_DONE) { NSAssert1(0, @"Error updating table: %s", errorMsg); } sqlite3_finalize(stmt); sqlite3_close(database); The first two values are updated but the last one remains 0 even if I'm writing a value like 1.5 or put a double variable with a different value Thanks

• SQL Azure server as unit of billing

  - by vtortola

  Hi, One of the azure training kit presentation says: Each account has zero or more logical servers Provisioned via a common portal Establishes a billing instrument Each logical server has one or more databases Contains metadata about database & usage Unit of authentication, geo-location, billing, reporting Generated DNS-based name Each database has standard SQL objects Users, Tables, Views, Indices, etc Unit of consistency So now I'm lost :D. Were not the databases themselves the units of billing? I mean, I thought that servers were just like logical containers and you were charged per number and size of databases. How servers are billed? Thanks.

• JsonStore.insert() causes exception in extjs

  - by kalan

  I have an EditorGridPanel with toolbar button to add new records. Everything works fine except one scenario. When I try to insert a record which already exists in database, server sends back: {"success":false,"message":"already exists","data":{}} but grid creates a new row marked with red triangle. If after that I try to insert a new record (even if it doesn't exist in database), everything works fine on the server side, but i get an 'uncaught exception' in firebug. It says: 'uncaught exception: Ext.data.DataReader: #realize was called with invalid remote-data. Please see the docs for DataReader#realize and review your DataReader configuration.' why is that?

• Newline not showing correctly in textbox

  - by TheGateKeeper

  I am loading a string from my database which among other things contains line breaks (\r\n). However, this isn't being rendered as a new line but instead as \r\n. If I type it directly in instead of loading it from a string, it works just fine but I need to be able to load it from a string. Any ideas? Edit: Upon closer inspection, it looks like the string is being returned as: Changed test7\\r\\nChanged test8\\r\\nChanged test9Changed test7 From the database. I tried running a .Replace(@"\\", @"\") on it but this had no effect at all. Any ideas?

• MD5 hash validation failing for unknown reason in PHP

  - by Sennheiser

  I'm writing a login form, and it converts the given password to an MD5 hash with md5($password), then matches it to an already-hashed record in my database. I know for sure that the database record is correct in this case. However, it doesn't log me in and claims the password is incorrect. Here's my code: $password = mysql_real_escape_string($_POST["password"]); ...more code... $passwordQuery = mysql_fetch_row(mysql_query(("SELECT password FROM users WHERE email = '$userEmail'"))); ...some code... elseif(md5($password) != $passwordQuery) { $_SESSION["noPass"] = "That password is incorrect."; } ...more code after... I tried pulling just the value of md5($password) and that matched up when I visually compared it. However, I can't get the comparison to work in PHP. Perhaps it is because the MySQL record is stored as text, and the MD5 is something else?

• MS SQL Server 2000 tables

  - by klork

  We currently have an MS SQL Server 2000 database with one table containing data for multiple users. The data is keyed by memberid which is an integer field. The table has a clustered index on memberid. The table is now about 200 million rows. Indexing and maintenance are becoming issues. We are debating splitting the table into one table per user model. This would imply that we would end up with a very large number of tables potentially upto the 2,147,483,647, considering just positive values. My questions: 1) Does anyone have any experience with a MS SQL Server (2000/2005) installation with millions of tables? 2) What are the implications of this architecture with regards to maintenance and access using Query Analyzer, Enterprise Manager etc. 3) What are the implications to having such a large number of indexes in a database instance. All comments are appreciated. Thanks

• How to manage changes to reports in .NET?

  - by Craig Johnston

  If I need to offer the ability to create, view and print reports from a .NET app, I see that there are 2 options: use a reporting component such as Microsoft.Reporting.WinForms.ReportViewer or Crystal Reports which saves a .rpt or similar template file that can be modified as required without having to re-compile the app use System.Drawing.Printing for reporting and store report template data in a database, which keeps things simpler and avoids problems with bulky third party reporting components If I want to be able to modify a report template (which would include layout and data fields) without having to re-compile the app, would the first option above achieve this? If I wanted to be able to modify the template without re-compiling the app, how could this be achieved with the second option? How could you store data representing the templates in a database such that it could be modified without having to re-compile the app?

• No unique bean of type [javax.persistence.EntityManager] is defined

  - by sebajb

  I am using JUnit 4 to test Dao Access with Spring (annotations) and JPA (hibernate). The datasource is configured through JNDI(Weblogic) with an ORacle(Backend). This persistence is configured with just the name and a RESOURCE_LOCAL transaction-type The application context file contains notations for annotations, JPA config, transactions, and default package and configuration for annotation detection. I am using Junit4 like so: ApplicationContext <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceUnitName" value="workRequest"/> <property name="dataSource" ref="dataSource" /> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="databasePlatform" value="${database.target}"/> <property name="showSql" value="${database.showSql}" /> <property name="generateDdl" value="${database.generateDdl}" /> </bean> </property> </bean> <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName"> <value>workRequest</value> </property> <property name="jndiEnvironment"> <props> <prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop> <prop key="java.naming.provider.url">t3://localhost:7001</prop> </props> </property> </bean> <bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" /> JUnit TestCase @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:applicationContext.xml" }) public class AssignmentDaoTest { private AssignmentDao assignmentDao; @Test public void readAll() { assertNotNull("assignmentDao cannot be null", assignmentDao); List assignments = assignmentDao.findAll(); assertNotNull("There are no assignments yet", assignments); } } regardless of what changes I make I get: No unique bean of type [javax.persistence.EntityManager] is defined Any hint on what this could be. I am running the tests inside eclipse.

• JTA Transaction: What happens if an exception happens but rollback is not called on the transaction?

  - by kellyfj

  We have some third party code wherein they do the following 1) Create a User Transaction e.g. txn = (UserTransaction)ctx.lookup( "UserTransaction" ); txn.begin( ); 2) Do some work persisting to the database (via JPA) to a MySQL database 3) txn.commit() They have Exception blocks but NONE of them call txn.rollback. Good coding practice says they NEED to call rollback if an exception occurs but my question is If the txn is not commited, and an exception occurs what is the negative effect of them NOT calling rollback?

• Forced closed only when put alphabetical string in edit text

  - by Abdullah Al Mubarok

  So, I make a checker if an id is in the database or not, the id is in numerical string, the type in database is char(6) though. So this is my code public class input extends Activity{ /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.input); final EditText edittext = (EditText)findViewById(R.id.editText1); Button button = (Button)findViewById(R.id.button1); button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { // TODO Auto-generated method stub String nopel = edittext.getText().toString(); if(nopel.length() == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ List<NameValuePair> pairs = new ArrayList<NameValuePair>(); pairs.add(new BasicNameValuePair("nopel", nopel)); JSON json_dp = new JSON(); JSONObject jobj_dp = json_dp.getJSON("http://10.0.2.2/KP/pdam/nopel.php", pairs); try { if(jobj_dp.getInt("row") == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ String snopel = jobj_dp.getString("nopel"); String snama = jobj_dp.getString("nama"); String salamat = jobj_dp.getString("alamat"); String sgolongan = jobj_dp.getString("golongan"); Intent i = new Intent(input.this, list.class); i.putExtra("nopel", snopel); i.putExtra("nama", snama); i.putExtra("alamat", salamat); i.putExtra("golongan", sgolongan); startActivity(i); } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }); } } the first check is to check if an input is null, it's going right for now, the second check is to check if an id in the database, and it's the problem. When I try some id in numerical value like "0001" or "02013" it's fine, and can run. but when I just got to put "abushd" it forced close. anyone know why I got this?

• facebook extended access token login

  - by Pota Onasys

  I have the following code: $facebook = new Facebook(array( 'appId' => ID, 'secret' => SECRET, 'cookie' => true)); $fb_uid = $facebook->getUser(); if($fb_uid) { // check if person with fb_uid as facebook id in database, // if so log them in. If not, register them. $fb_user = $facebook->api('/' . $fb_uid); I then get their email address using $fb_user['email'] and facebook_id and store in the database as a means to log them in the future Sometimes $fb_uid returns false even though the person is logged in using facebook ... I think it is because the access token expires. how can I change this code to incorporate the extended access token to log in the user to my site? offline access token is deprecated, so I need to use the extended access token.

• Is there any way to synchronize AD users with Office 365 but still be able to edit them online?

  - by Massimo

  I'm performing a migration to Office 365 from a third-party mail server (MDaemon); the local Active Directory doesn't include any Exchange server, and never had any. We will need directory synchronization in order to enable users to log on to Office 365 using their domain credentials; but it seems that as soon as you enable directory synchronization, you can't perform any action anymore on Office 365 users: all changes need to be made on the local Active Directory, and then replicated by the synchronization process. For ordinary users with a single e-mail address and standard features, this is not a big problem; but what about users which need an additional address? What if I need to configure some nonstandard setting, like "hide from address list" or a custom mailbox quota? From what I've gathered, the only supported way to do this, as you can't directly edit Office 365 objects anymore after synchronization is enabled, is to extend the local AD schema with Exchange attributes, and then manually edit them (!). Or, you can install at least one local Exchange server, and then use the Exchange administrative tools to configure the required settings. Is this correct or am I missing something? Is there any way to synchronize user accounts and password, but still be able to edit user settings directly in Office 365? If not (everything really needs to be set locally and then synchronized), is there any simpler way to do this than manually editing LDAP attributes or installing a local Exchange server?
