What are the approaches to updating materialized views in Oracle when underlying tables are updated frequently?

I am a web developer and maintain a web app that tracks orders, customers, products, etc. that my customer uses internally. I'm using Oracle 12c, which is hosted on AWS RDS. My client has just switched some other systems so we're at a point where the data structures have changed and I'm using a new schema in Oracle to store new data in the new structures.

So that the web app does not have to be revised to work with new data structures, it was decided to implement materialized views in Oracle that combine the new data from the new schema (manipulated into the "legacy structure"). along with the legacy data.

Now I have to take care of updating these materialized views so that the web app can always access the latest data. Ideally, the relevant materialized views will be updated when I get a new record in the new schema. However, I may get new data every few seconds during working hours. A compromise is fine – if the materialized views are out of date by a few minutes (maybe 5 or (less ideally) 10 minutes), this can be an acceptable situation.

My question is, what approach should I take to refresh these materialized views? I don't want to overload Oracle with constant updates, and the web app should give users a good user experience reading / writing data from / to Oracle. I am far from being an Oracle / DB expert, so I'm not sure what options are available. I think I could just have a cron job that runs every 5 minutes or something to refresh outdated materialized views one by one, but I wonder if this approach is a bit naive.

In reality, I'm dealing with 14 materialized views (for now), and my tests take up to 2.5 minutes for some of them to complete a full update.

7 – Update user interface lists modules / topics that have already been updated

I have a D7 (7.69) page. I can update a module in both development and production (via the web user interface – / admin / modules / update), apparently successful, but after that this module remains listed as required for an update with Installed version and Recommended version just like that.


Adminimal – Responsive Administration Theme (Theme)
Installed version 7.x-1.26
Recommended version 7.x-1.26

(I've seen it with topics like the above and modules like views).

I tried:

  • Clear the cache
  • Download a clean latest version to a new directory and compare the md5hashes of all files between the two (as well as simpler checks like the module) .the information File.)
  • Delete the module / topic directory and replace it with a freshly extracted .tar.gz
  • Check for pending database updates

Is there anything else that could cause it to get stuck?

I looked at that system Table – specifically the system.info Field – but nothing looks "wrong".

8 – When will the user interface translation be updated?

The search for updates is done in the cron job & # 39; Interface Translation & # 39; called
If you deactivate the cron job or deactivate the "Check for updates" on the page you mentioned, no automatic update will be carried out for cron runs.

The other methods you name are manual methods.

There is another method in the core user interface if you manually translate the interface text on the admin/config/regional/translate Page.

It also depends on the "Import behavior" settings admin/config/regional/translate/settings Page. When the import is updated.

I know that this is available in the core user interface.

You can of course also contribute modules other than Drush or Drupal Console to update your translations.
Or Composer see https://github.com/drupal-composer/drupal-l10n

magento 1.9 – User-defined product attributes are no longer updated via the dashboard or programmatically

Up until a few months ago, everything worked perfectly on this Magento 1 instance.

I appended about 20 custom attributes to an attribute set for a product. Two of them don't save. If you change the value and click Save, is displayed Product has been saved but the value is the same.

I tried re-indexing, disabling the cache and storing it programmatically, nothing worked anymore. When I create new attributes, they are not saved.

How can I fix this because these attributes previously worked?

Audio – The main system sounds from the previous installation cannot be changed. – Wrong file names cannot be updated on Android 9

I tried changing the notification sound on my Samsung Galaxy S9 + (installed a year ago)
When I press the sound's "Name" button, a window opens (see screen shot) that shows the name of the current audio file and a spin button while the system is searching the file.

The problem is that the file does not exist (not fully displayed) because the file name shown is the full name on my previous phone (the name that starts with – contains the name "four_digits-four_digit" that came with my SD card) The predecessor is the telephone.

Only "Cancel" can be carried out.

My (temporary?) Conclusion is that if you change the default ringtones and notification tones, they will be saved in a directory (external-storage / 9999-9999 / android //. M4a) when Android's system configuration changes to a new one Phone (S7e to S9 +) is restored:

  • the references of the file are retained (of course, no longer valid, note: I found the file on a & backup copy of my old SD card)
  • If you want to change the sound, the system searches for the file and (of course) does not find it. No error is raised and the spinner continues to run until it times out, canceling the process.

Therefore, it is currently not possible to change the sounds under Android 9, kernel version 4.9.59-17174122, if you have previously changed the audio file (s) by default for a file saved on the external memory.

If you know of a solution, Samsung suggests reinitializing the phone, but this can't change anything because the same file name is restored and not restoring your configuration is the lonely remaining solution!

If I summarize, there are two questions:

  • The fact that when the system parameter is migrated from one phone to another, the file defined on the SD card is not checked (and then a process "find it" if it is not found) – check the integrity during installation
  • The fact that the sound's update function does not check the existence of the associated file and then does not suggest forgetting it or finding it in another directory. – Check the integrity when executing and handle the error

My conclusion: Until Google has to debug this, I have to keep the same ringing and notification tone.

sharepoint online – Highlighted content that only shows the original title of the document does not change when the title is updated

I embedded a highlighted content web part into my Modern SharePoint Online page and configured it to display files from a document library.

The problem I have is: If I change the title of a document directly in the document library, the new title in the Highlighed Content web part is not updated. The old title is still displayed, regardless of how much time passes (days, months, etc.). Do I miss something?

Windows – Powershell cannot access packages / "NuGet" package providers after the security configuration has been updated

I upgraded a server with a mof / dsc configuration and essentially changed various permissions / registry keys to ensure security. To a certain extent, this was generated automatically. I have a list of all the items configured, but it is a little difficult to read and not very clear.

After the process, Powershell cannot update new packages or set the default repository.

I don't think this is anything specific to NuGet, and my guess is that it's related to some more basic file permissions. From what I can say, NuGet is installed on my system. I know it was installed before applying this configuration and the form I can say was not removed.

I checked a working server twice and the authorization for the NuGet DLL looks the same.

Here is an example of an error:

Entities – Where is the revision translation affected updated?

In a custom entity that I created, when I view the version history, it finds that it is mixed with other language versions. I found that the node is doing this check but found out whether revision_translation_affected is set to 1. In the node, it is set to 1 if this revision language is being edited and to zero if this is not the case.

For some reason it is always set to 1 for my custom entity, but I have no idea where to change it.
