  • Is there any trick to join and use Windows 8/8.1 with Samba 4 (4.1.6)?

    - by tenshimsm
    It seems that Samba doesn't like at all. I've followed various tutorials and I can't get Windows 8 to work properly with a Ubuntu Server as domain controller. This week i've downloaded ubuntu 14.04 lts and set a fast domain configuration. As usual all other Windows version (XP and 7) work but the newest M$ nightmare doesn't. In this try it doesn't even join the domain, keeps saying the my username or password are wrong. My /etc/samba/smb.conf # Global parameters [global] workgroup = DOMAIN realm = DOMAIN.LAN netbios name = DOM server role = active directory domain controller dns forwarder = 8.8.8.8 idmap_ldb:use rfc2307 = yes [netlogon] path = /var/lib/samba/sysvol/domain.lan/scripts read only = No [sysvol] path = /var/lib/samba/sysvol read only = No [test] directory mode = 0750 path = /SHARES/test read only = no Does anyone have a tutorial that really works? Because I've tried many, each one with different configurations that works only with the people that made them. And is there a way to import my old AD users, computers and ID in a way that I won't need to rejoin all computers?

  • Core Data strategy using in memory cache, or no core data at all?

    - by randombits
    I have a user interface where the user can check off a bunch of items from a tableview, almost like a todo list. The items are populated from a Core Data stack. I need to be able to take all of the items they're clicking through and put them into a "temporary" shopping cart. Once they're in the shopping cart, users can go through the list and remove the items, or just submit them to a server. The thing is, the selected items are temporary just like an internet based shopping cart. It's nothing something that gets persisted once the application closes. Once the view is no longer in display, I can assume that the shopping cart is safe to discard. What's the best way to approach this? Since the user is essentially clicking on instances that map back to a Core Data entity .. should I setup a different persistence store such as in memory and add that store to my managed object context?

    - by kate
    Hi, We have three tables .We need to get data from these tables based upon particular conditions. Like if TableA.columv=TableB.columc=tableC.column then get data. We are using value objects to map Objects to relations. Question is how to maintain these relation ships in value objects. And how to retrieve data from it. We have one value object per table.

  • Database(Partitions) related query.... Please suggest..........

    - by AGeek
    The Query is as follows:- We have an oracle schema, with tables partitioned. -- Need to make one of the partition offline. (How to achieve this,, or have thought of assigning each partition, a different tablespace, and then making that tablespace offline) any other way out possible so as to avoid making so many tablespaces???? -- Then, copy the data files/ logs related to that partition to the temporary storage..... how to achieve this thing... any docs related to the same.... -- Then We make this partition / related tablespace online... -- Then we create a second schema with the same tables as above..... -- Copy the partition data from temporary storage to this table. (How this can be achieved,,, any specific doc??? -- Then verifying to the data is accessible in all respects..... If possible, let's discuss to find out the solution........ Thanks....

  • Query scope within a table trigger in an Oracle database

    - by sisslack
    I'm been trying to write a table trigger the queries another table that is outside the schema where the trigger will reside. Is this possible? It seems like I have no problem querying tables in my schema but I get: Error: ORA-00942: table or view does not exist when trying trying to query tables outside my schema. The documentation seems to elude to this notion, but it's not 100% clear to me.

  • Database design advice needed.

    - by user346271
    Hi all, I'm a lone developer for a telecoms company, and am after some database design advice from anyone with a bit of time to answer. I am inserting into one table ~2 million rows each day, these tables then get archived and compressed on a monthly basis. Each monthly table contains ~15,000,000 rows. Although this is increasing month on month. For every insert I do above I am combining the data from rows which belong together and creating another "correlated" table. This table is currently not being archived, as I need to make sure I never miss an update to the correlated table. (Hope that makes sense) Although in general this information should remain fairly static after a couple of days of processing. All of the above is working perfectly. However my company now wishes to perform some stats against this data, and these tables are getting too large to provide the results in what would be deemed a reasonable time. Even with the appropriate indexes set. So I guess after all the above my question is quite simple. Should I write a script which groups the data from my correlated table into smaller tables. Or should I store the queries result sets in something like memcache? I'm already using mysqls cache, but due to having limited control over how long the data is stored for, it's not working ideally. The main advantages I can see of using something like memcache: No blocking on my correlated table after the query has been cashed. Greater flexibility of sharing the collected data between the backend collector and front end processor. (i.e custom reports could be written in the backend and the results of these stored in the cache under a key which then gets shared with anyone who would want to see the data of this report) Redundancy and scalability if we start sharing this data with a large amount of customers. The main disadvantages I can see of using something like memcache: Data is not persistent if machine is rebooted / cache is flushed. The main advantages of using MySql Persistent data. Less code changes (although adding something like memcache is trivial anyway) The main disadvantages of using MySql Have to define table templates every time I want to store provide a new set of grouped data. Have to write a program which loops through the correlated data and fills these new tables. Potentially will still grow slower as the data continues to be filled. Apologies for quite a long question. It's helped me to write down these thoughts here anyway, and any advice/help/experience with dealing with this sort of problem would be greatly appreciated. Many thanks. Alan

  • How to install Qt on Windows after building?

    - by Piotr Dobrogost
    I can't find any information on how to install Qt built on Windows. In wiki article How to set up shadow builds on Mac and Linux there's description of -prefix option in configure script but this option is not available on Windows. I know I can use Qt right from the build folder but it does not seem the right thing not to perform an install step. One problem with this approach is size; Qt's build folder takes about 4GB space whereas after installing using binary installer Qt takes about 1GB space. I guess the difference is due to temporary files created during building. I hope some install procedure would install (copy) only needed files leaving temporary files in the build folder.

    Wikipedia defines a 'typical' ETL cycle as : Cycle initiation Build reference data Extract (from sources) Validate Transform (clean, apply business rules, check for data integrity, create aggregates or disaggregates) Stage (load into staging tables, if used) Audit reports (for example, on compliance with business rules. Also, in case of failure, helps to diagnose/repair) Publish (to target tables) Archive Clean up ..What is meant by 'Build reference data'?

  • SSRS and cached reports

    - by Tabloo Quijico
    Hi, I'm opening an SSRS2008 report using the http://server/reportserver/... syntax, outputting directly a PDF copy. This report has several parameters. The problem is that, despite making changes to the report, and clearing the browser's temporary files cache.. if I request the same report (i.e. same parameters) - the old report is returned. In the report execution properties, I have "Always run this report with the most recent data" and "Do not cache temporary copies of this report" selected. It's not just a case of caching data, but the entire report (including formatting, e.g. I deleted a page from the report yet it was still being shown...) and as I haven't specifically chosen to perform any caching I'm a little concerned and clearly don't fully understand what's going on! Any tips?

  • Three-way full outer join in SQLite

    - by Vince
    I have three tables with a common key field, and I need to join them on this key. Given SQLite doesn't have full outer or right joins, I've used the full outer join without right join technique on Wikipedia with much success. But I'm curious, how would one use this technique to join three tables by a common key? What are the efficiency impacts of this (the current query takes about ten minutes)? Thanks!

  • Lookups in Multi-Tenant Database

    - by Huthaifa Afanah
    I am developing a SaaS application and I am looking for the best way to design lookup tables, taking in consideration: The look-up tables will have predefined data shared among all the tenants Each tenant must have the ability to extend the look-up table with his own data e.g adding a car class not defined I am thinking about adding TenantID column to each lookup and add the predefined data with setting that column to some value which represents the "Super Tenant" that belongs to the system itself

  • Oracle join issue

    - by acadia
    Hello, I have 3 tables and I am joining these 2 tables as follows: SELECT EMP.FNAME,EMP.LNAME,EMP.AGE,EMPD.TQ,EMPD.TA,CTY.CITY_NAME FROM EMPLOYEE EMP,EMPLOYEE_DETAIL EMPD, CITY CTY WHERE EMP.EMP_ID=EMPD.EMP_ID AND EMPD_CITY_ID=CTY.CITY_ID I want to display records even if City record is not in CITY table. For eg. if City_ID record for say 10 is not in City table but there is an employee detail record with City_id 10 it should display City_name as null instead of not displaying the record at all. Appreciate your help

  • How to temporarily change all default user settings without destroying the original?

    - by mystify
    My app is based strongly on a lot of NSUserDefault keys and values. I want to implement a temporary defaults profile which the user can activate to get a special task done easily. For this, some of the user defaults must be changed temporarily so the app adjusts it's interface appropriately. I started to just manually change those NSUserDefaults settings, but this also destroys the user's original settings. Is it possible to keep a backup of the user's NSUserDefault settings and restore them after the user quits the temporary mode or the app? Like I see it, NSUserDefaults actually is just an NSMutableDictionary which is generated out of a plist file. So I would just make a deep copy of that and later assign that copy somehow back to NSUserDefaults?

  • IOC are at the class level, but what about database conflicts?

    - by mrblah
    With IOC I understand you can substitue implementations out by merely editing a configuration file etc. BUT, what happens when the classes are married to particular database tables and sprocs, you can't just swap out an implementation since the classes/entities are tied to particular tables and stored procedures. Am I right here?
