Level - data retention applications

During development, I noticed, that each app deployment is seen by the system as an installation fresh app (as opposed to the deployment on Android itself, where the properties of the app are stored).

We are at the point where we want to release the first update of our app, and the app will be substantially different from the first version. But we want to keep the application settings, such as preferences and user account information. During development, this information has been lost with each new deployment.

How is - that it is run in production? Our app will lose all of its data on the upgrade?

Update BlackBerry world can be tested?

Kind regards

Hey Rok,.

In my tests, it seems that the upgrade of the application retains the settings/properties, at least it does with SharedPreferences. Test yourself against the latest 10.2.1?

Application upgrade via BlackBerry World will preserve the previous settings/properties as well. You can try setting up a Sandbox account in the portal provider to test the upgrade of the application.

  • Re: How does the data retention?

    Hello guys

    How does the conservation of data in vC Ops? In the document it says data retention in the company is 900 days. But in the vSphere user interface, we can keep up to 4 years, which is by default and the minimum level. These two does not?

    There are also resolutions different weeks, monthly, quarterly, and annual. Suppose for example that if we maintain weekly resolution as 12 weeks and months 10, all the quarters 9 and annual 5 years as shown in the picture how it works? I mean after 12 weeks the data will be deleted, but we said 5 years for recall information. How this is achieved.

    Please help me

    Let me be more specific:

    1. the colelctor collects data interval 20 seconds every 5 min

    2. it is wrapped in a 5 min avg and max value.

    3. these values 5 min is rolled up to hourly, daily, weekly... ect... for two reasons: capacity and analysis of dynamic thresholds which is stored in two databases diffenent calculations.

    It does not compress the stats... it gets stats avg. (Analysis uses avg to get trends used for forcasting ability... ect)

  • How can I dynamically change the Format of Date of Application?

    Hello world...

    In my application (v 3.2) I let the user set the date format of app dynamically by a "preference" value, they can change on the road.
    I then take the format they take and affect their value (ie: ME-DD-YYYY) and pad "Hh: mi" for it and use it as the PICK_DATE_FORMAT_MASK that works very well for most of the selectors of dates.

    The problem I have is that some date picker, I use the application does not require the hh: mi, they need just the part of ME-DD-YYYY. I could use the NLS_DATE_FORMAT for this? I may be able to use the selectors of dates with the "format of date of application use? It doesn't seem to work for me.

    In other words, I need essentially 2 date formats for my selectors of application dates; 1 for just the dates and 1 for dates, including time. And these 2 formats are selected by the user by setting a preference of app dynamically at run time.

    Not sure if I feel here... any idea?

    Thank you!

    You must use the element of the application in the installation of your application, so when you select in your control, you would use the date format of application level. You can change the level application through code or control element.

  • Advice required - what UI component to a data browser application

    I am building a data browser application and to display a row of data for each item in the database in one window scrolling.  I wonder advice on what user interface component to use.  OS 5.0 or later only.

    The app will have at least 500 lines of data - maybe more up to a mile or two.  So I'm afraid that if I load all the data in a ListField or ObjectListField I'll use scads of memory to display the data - which most scrolls off the screen.

    I could page the next page of data instead of scrolling dynamically, but that degrades the user experience.  I could build a data reader multi-threaded which fills a video page before and reduced the amount of data contained in the list at any time - but hope that there is a better way.

    Advice appreciated...

    This isn't an answer to the question that is asked but, you mentioned the quality of the experience 'user' as a factor, so here it goes...

    Unless it is a scientific application, I submit respectfully that the average user does not scroll on lines of 500-1000 of data, regardless of the nature of the UI container.

    How about a query/filter front page, for example as the OS5 built in search of e-mail, perhaps associated with a sort function... to cut the results to a reasonable number, then present in a list field... who can easily manipulate for example, 100 records.

    Anyway, just my $0.02

  • Dynamically change the Format of Date of Application

    Hi all

    I am looking for a possibility to change the format of date of Application in globalization attributes dynamically according to the user.

    Something likeAPEX_UTIL.SET_SESSION_TIME_ZONE but for the date format.

    Does anybody know how it works?

    In detail:

    I want dates in interactive reports display in a specific date format.

    If I put the following in the attributes of 'security' - call the virtual private database PL/SQL to define the security context:

    BEGIN

    If password = "MY_TEST_USER" then

    run immediately "alter session set nls_calendar =" English Hijrah "';"

    run immediately "alter session set nls_date_format =" DD-MM-YYYY "';"

    end if;

    END;

    Then, the dates are indicated correctly in reports interactive but not in the Action menu-> filter.

    If I put date_format = "DD-MM-YYYY" in the attributes of the globalization, it works very well in the interactive report filter.

    The problem is that I want to set this attribute only for some users.

    Thank's,

    Kirsten

    (APEX 4.0/APEX 4.2)

    Because you can use string syntax of substitution for the attributes of the globalization, for example, you could create an element of the AI_DATE_FORMAT application, reference & AI_DATE_FORMAT. and fill out the application element according to certain parameters in the code after the authentication of the authentication system (for example: get a parameter of an array of parameters user or somesuch).

  • Less than the date of application


    Than the date of application.

    How to get out the query set so even if a T_DATE is less than the Admission_date the query should display all the data.

    ID T_DATE Admission_date
    101 4/1/2001-5/1/2001
    102 4/1/2001-5/1/2001

    105 4/1/2001-5/1/2001
    106 6/1/2001-5/1/2001

    Even if a T_DATE is less than the date of Admission, the application must pick up all the data.

    Select * from X where T_DATE < Admission_Date gives only

    101 4/1/2001-5/1/2001
    102 4/1/2001-5/1/2001
    103 4/1/2001-5/1/2001
    104 4/1/2001-5/1/2001

    Yet the missing 106.

    Thank you..

    Hello

    You can change the solution in response #2 like this:

    WITH got_ok_cnt AS

    (

    SELECT *- or display the columns that you want to

    , COUNT (CASE WHEN T_DATE)< admission_date="" then="" 1="">

    COURSES (PARTITION BY id) AS ok_cnt

    X

    )

    SELECT *- or the list of all columns except ok_cnt

    OF got_ok_cnt

    WHERE ok_cnt > = 1

  • vCenter data retention policies when does it take effect

    I'm not enough on my space of vcenter. If I set the data retention policy to 6 months, should I immediately remove tasks and events more than six months, or it marks just all new task and the event should be deleted within 6 months. I just wanted to see if I would get immediate space savings.

    Hey Stan,

    Purge scripts are set to run once a year, once a month, once a week and once per day because there are four procedures that work both to collect and to purge the data. You can manually run the purge by just running the default procedures stored in SQL Management Studio after connecting to your virtual Center DB and that would go very well indeed, and I guess that max age settings are what you would find already set at 6 months in the scripts, if you have already made changes in the GUI!

  • Graphic data retention for VCenter 5 device

    Hi all

    I noticed a month previously, our graphic retention went up to 1 month of data collection.

    I used to have all the months of graphs since installation.

    I read somewhere that you could go to:

    vCenter Server Settings-> data retention policy.

    It has been verified to 356 days. I unchecked to see if it worked and restarted.

    Nope.

    Something has changed since installation, and what I can't understand.

    I did the last update, hoping that would help, but it didn't.

    Does anyone know where I could solve this?

    Thank you!

    Now, it's a problem...

    The best solution for your missing perf stats must publish the next update:

    DB2 "update VPX_STAT_INTERVAL_DEF set INTERVAL_LENGTH = 31536000 where INTERVAL_SEQ_NUM = 3".

    Unfortunately this will not restore your data of perf, but you won't have the same problem with the lack of statistical data.

  • Data retention

    In the United Kingdom, there is specific legislation around data retention that stores pii (personally identifiable information) only as long as is necessary for business purposes (data protection Act). I just wonder how to challenge that needs a DBA. For example, an oracle database that houses the HR/pay your personal information? You have set procedures to remove the data of the ex employees after x number of months? Is this practice? You have to go through your backups and remove all traces of this information there as well? It seems a bit of a nightmare for my I was wondering how do you to address this issue for any database, you support this process/store PII?

    One of the problems with Public Transport chip that is currently implemented in the Netherlands is the backoffice is inconsistent with the law of protection of personal information and sensitive data to privacy too long. That's according to the authority for the protection of personal information. Some politicians that the backoffice does not store information that moves passengers have made at all.

    And Yes, I was involved with HR systems, where information on missing employees was not deleted, sometimes not even after 5 years (for tax reasons, financial information must be kept for 5 years).

  • Identify the best way to transfer data between applications in Essbase

    Hello Experts,


    One of my clients uses Hyperion System 9.3.1 and they try to understand if the partitioning might be a way to automate the transfer of data between applications Essbase (using the partitioning of replication).

    The challenge, they say, is that they may need to send the budget a source application (SLVQ) data to an application (consolidated) target. Data can be changed in Conso and returned to the SLVQ for review.

    They get warnings when they define partitions in both directions because the partitions are overlapping, but it works.

    Are there concepts or reasons why they should not use this function (transfer in both directions)? Is this something that is used by other companies?

    Their alternative is to export data in text file, then reload with rule files. It seems more difficult to define (MaxL scripts-> text files-> rules of files) with more chances of getting errors. Is there some other effective solutions which we do not understand?

    Please suggest.

    Thanks in advance

    Kind regards
    Jingle

    Hi Lisa,
    other than the scores, text file
    There are two more, according to my knowledge

    1 XREF
    2 HAL (Hyperion Application Link) using adapters essbase

    We use the XREF and HAL to our company to transfer data between applications according to the needs.
    I hope this helps.

  • Pass data between applications value reference

    The issue is that data application reference value is local to the application instance, or can be transferred between different applications.

    I have a main application that acquires the table of 100 MB and I need to use these data in a dll. Obviously, I don't want to send table, reference would be better. Both applications are generated in labview 2011.

    The second question is whether reference data value can be converted to a string (type cast or flatten to a string) and back. For example with DAQmx tasks flatten to a string does not work.

    Alexander_Sobolev wrote:

    It's value application data reference is local to the application instance.

    Yes.

    or may be transferred between applications.

    Laughing out loud

    The second question is whether reference data value can be converted to a string (type cast or flatten to a string) and back.

    Yes, but only means something in the app instance appeared to reference.

    You will want to perhaps give more details on what are your real needs, but keep in mind that play with memory directly in LV is not so simple, as he does all he can to hide these details you.

    If you pass a pointer to an array to a DLL, you can configure the DLL for this call. If you want to get an accurate picture of LV in memory address and passing around, this isn't something LV supports and you shouldn't do that because the memory should not be controlled by more than one master at any time in time.

    LV has functions of memory allocation and to get the pointer back, but requiring explicit calls.

    Anyway, I have no real experience with this. If you want to read materials, there are at least two users here with much more knowledge on the subject and you can go through their messages or search and filter for their post - rolfk and nathand.

  • Custom data retention policy

    Hi all

    Is it possible to set up below the retention to Foglight (5.6.10) policy.

    * Save 10 minutes for 90 days and then purge *.

    Kind regards

    Roshan Varughese

    Hi Roshan,

    You must set all three generations in the custom retention policy to preserve data for 10 minutes.

    Please find the custom in FMS UI retention policy under: management data/servers/server management / retention policy/policy current. Here, select the menu drop-down and click custom.

    Once there you should be able to select 10 minutes for each generation, then purge the data after 3 months. (see image below)

    Keep in mind that political detention is very granular and the size of your database is likely to increase. Also, when you use larger slots in the user interface, the server will have to deal with more values and will add a certain amount of overhead.

    More information in Foglight documentation - creation of custom retention policies.

    Gaston.
