  • Duplicate free/busy or full calendar information between two exchange servers

    - by Wayne Arthurton
    We have acquired a new entity with their own AD/Exchange environment. Until they fully join our domain, we need to sync their exchange calendars or minimally free/busy for users. All users in the acquisition have a new account in our organization. We have considered a number of options including CalDAV, but nothing seems to meet our needs. Even a client solutions to update the NEW server with the free/busy would be workable.

  • Any free Exchange hosts out there?

    - by Pure.Krome
    Hi folks, Are there any free Microsoft Exchange hosted solutions? I understand that Microsoft Exchange is a paid/licensed product, but I was curious if there might be a host that has a free hosting model (e.g. for <= 3 mailboxes per domain)? Larger mail boxes per domain == cost. ?? Finally, please refrain from suggesting other mail services (eg. sendmail, etc).

  • Are there free FTP serer backup repositories

    - by Saif Bechan
    I was wondering if there is a free service that provides a repository for your backups. These are backups of my server, there are usually about 200mb. I want to FTP the last 2 or 3. I am looking for a service that maybe provide some gigs of space and with FTP access. Looking at email providers such as gmail and hotmail that give you a couple of gigs of free space, this should also be possible or am i horribly wrong.

  • Convert byte array from Oracle RAW to System.Guid?

    - by Cory McCarty
    My app interacts with both Oracle and SQL Server databases using a custom data access layer written in ADO.NET using DataReaders. Right now I'm having a problem with the conversion between GUIDs (which we use for primary keys) and the Oracle RAW datatype. Inserts into oracle are fine (I just use the ToByteArray() method on System.Guid). The problem is converting back to System.Guid when I load records from the database. Currently, I'm using the byte array I get from ADO.NET to pass into the constructor for System.Guid. This appears to be working, but the Guids that appear in the database do not correspond to the Guids I'm generating in this manner. I can't change the database schema or the query (since it's reused for SQL Server). I need code to convert the byte array from Oracle into the correct Guid.

  • kill -9 doesn't work

    - by Daniel
    I have a server with 3 oracle instances on it, and the file system is nfs with netapp. After shutdown the databases, one process for each database doesn't quit for a long time. Each kill -i doesn't work. I tried to truss, pfile it, the command through error. And iostat shows there are lots of IO to the netapp server. So someone said the process was busy writing data to remote netapp server, and before the write complete, it won't quit. So what need to be done was just wait until all the IO was done. After wait for longer time (about 1.5 hours), the processes exit. So my question is: how can a process ignore the kill signal? As far as I know, if we kill -9, it will stop immediately. Do you encounter such situation kill -i doesn't kill the process right away?

  • (Oracle Performance) Will a query based on a view limit the view using the where clause?

    - by BestPractices
    In Oracle (10g), when I use a View (not Materialized View), does Oracle take into account the where clause when it executes the view? Let's say I have: MY_VIEW = SELECT * FROM PERSON P, ORDERS O WHERE P.P_ID = O.P_ID And I then execute the following: SELECT * FROM MY_VIEW WHERE MY_VIEW.P_ID = '1234' When this executes, does oracle first execute the query for the view and THEN filter it based on my where clause (where MY_VIEW.P_ID = '1234') or does it do this filtering as part of the execution of the view? If it does not do the latter, and P_ID had an index, would I also lose out on the indexing capability since Oracle would be executing my query against the view which doesn't have the index rather than the base table which has the index?

  • Sef-packed training kit practice tests

    - by Costa
    Hi I have a book called .Net framework 2.0 application development foundation, self-packed training kit by Tony Northup and Shawn wildermuth. the book CD contains practice tests, Can I rely on this CD to take the exam, or it will be just like the book itself, a wast of money? someone rely on it and success? I am not talking about memorizing or cheating the exam I am talking about studying and practice it. Also When I visit MS website they did not determine the number of questions, type of questions, or the time, someone have this info? Thanks

  • Why Banks or Financial Companies prefer Oracle than other RDBMS for their "Core" systems?

    - by edwin.nathaniel
    I'd like to know why most Banks or Financial companies prefer Oracle than other RDBMS for their core systems (the absolutely minimum features that a Bank must support). I found a few answers that didn't satisfy me. For example: Oracle has more features. But features for what? Can't you implement that in application level if you were not using Oracle? Could someone please describe a bit more technical but still on high-level overview of what the bank needs and how Oracle would solve it and the others can't or don't have the features yet? I came from the web-app (web 2.0) crowd who normally hear news about MySQL, PostgreSQL or even key-value/column-oriented storage solution. I have almost zero knowledge on how Banks or Financial companies operates from technical perspective. Thank you, Ed

  • Bug in the official Android Fragments training sample?

    - by Jeff Axelrod
    It seems to me that there must be a bug in the Android Fragments demo. As background, Fragments are apparently sometimes instantiated by the Android OS and thus need a public no-arg constructor: All subclasses of Fragment must include a public empty constructor. The framework will often re-instantiate a fragment class when needed, in particular during state restore, and needs to be able to find this constructor to instantiate it. If the empty constructor is not available, a runtime exception will occur in some cases during state restore. But the NewsReader demo from the official Android training on Fragments constructs the HeadlinesFragment class and configures it with setOnHeadlineSelectedListener(this) from NewsReaderActivity.onCreate(). If the Android OS re-instantiates this fragment, the mHeadlineSelectedListener field will be null because HeadlinesFragment doesn't save or restore its state. Is this a bug or am I missing something?

  • Connection error in java website. Tnsping shows that the service is running

    - by user1439090
    I have a java website application running in windows 7 which uses oracle database for its functionalities. The database has default SID name orcl. When I use tnsping, I can see that the orcl service is active. Also most of the application is working fine except for one part.

  • Oracle why does creating trigger fail when there is a field called timestamp?

    - by Omar Kooheji
    I've just wasted the past two hours of my life trying to create a table with an auto incrementing primary key bases on this tutorial, The tutorial is great the issue I've been encountering is that the Create Target fails if I have a column which is a timestamp and a table that is called timestamp in the same table... Why doesn't oracle flag this as being an issue when I create the table? Here is the Sequence of commands I enter: Creating the Table: CREATE TABLE myTable (id NUMBER PRIMARY KEY, field1 TIMESTAMP(6), timeStamp NUMBER, ); Creating the Sequence: CREATE SEQUENCE test_sequence START WITH 1 INCREMENT BY 1; Creating the trigger: CREATE OR REPLACE TRIGGER test_trigger BEFORE INSERT ON myTable REFERENCING NEW AS NEW FOR EACH ROW BEGIN SELECT test_sequence.nextval INTO :NEW.ID FROM dual; END; / Here is the error message I get: ORA-06552: PL/SQL: Compilation unit analysis terminated ORA-06553: PLS-320: the declaration of the type of this expression is incomplete or malformed Any combination that does not have the two lines with a the word "timestamp" in them works fine. I would have thought the syntax would be enough to differentiate between the keyword and a column name. As I've said I don't understand why the table is created fine but oracle falls over when I try to create the trigger... CLARIFICATION I know that the issue is that there is a column called timestamp which may or may not be a keyword. MY issue is why it barfed when I tried to create a trigger and not when I created the table, I would have at least expected a warning. That said having used Oracle for a few hours, it seems a lot less verbose in it's error reporting, Maybe just because I'm using the express version though. If this is a bug in Oracle how would one who doesn't have a support contract go about reporting it? I'm just playing around with the express version because I have to migrate some code from MySQL to Oracle.

  • Essential Training Topics for Supervisors of ASP.NET Developers

    - by Dave Johnson
    I have a co-worker who supervises a group of ASP.NET developers who are doing lots of ASP.NET/SQL Server apps. My co-worker was very technical at one time, but his last programming assignment was writing Fortran code in the 1980s. He has asked me to help him gain a deeper knowledge of ASP.NET Web application development to equip him in his supervisory role. I will be spending an hour every other week with him providing training, and he will probably not have a lot of time to commit otherwise. What would you recommend as topics to cover, tutorial resources, etc. so that I can help him get up to speed in his role as a supervisor of ASP.NET developers?

  • Trying to connect internally to Oracle, getting an idle instance?

    So I have an Oracle instance, and I know it's running on this system, I've su'd to the oracle user, and I'm trying to connect using "/ as sysdba". However, when I do connect, it says the instance is idle. I know the database is up and opened, because my application's talking to it.

  • When using Oracle load balancing and ADO.NET, how do you know which host the command executed on?

    - by Leeks and Leaks
    It's possible to use Microsoft's OracleClient assembly to connect to an Oracle database, and using Oracle's connection string format, set it up to use load balancing, provided your Oracle environment supports it. The question I have is how do you know after the fact, which db host the command actually executed against? Is there a way to retrieve the machine name from the load balanced set of machines?
