I want to change ip for secondary storage. Is it possible to change? If possible please show me the right place.
If cannot change ip please guide me how to delete it from UI and database.
Thanks.
What you will find easiest is to spin up a new SSVM and then migrate over to it. The migration process will involve some SQL - this Citrix Knowledgebase answer will point you in the general direction of what needs to be done.

I'm setting up an application which is a set of Mircroservices consuming a Cloud SQL DB in GCP. My queries are -
I want to set up HA for Cloud SQL in across regions(primary region and a secondary region with active replication enabled). I do not see any out of the box set up from Google Cloud to achieve the same. Out of the box HA for Cloud SQL 2nd Gen is to have a HA instance in the same region in another zone in the same region. Please provide the best practice to achieve the same.
All the microservices should be using private ip to do actions on this MySQL. How do set this up?
Is there any native support from MySQL to enable Active replication to another region?
Is it possible to set up manual backup as per customer requirements? I do understand automatic backup available.To meet RPO RTO requirements want to customize db backup frequency - is that possible?

You can use the external master feature to replicate to an instance in another zone.
All the microservices should be using private ip to do actions on this MySQL. How do set this up?
Instructions for Private IP setup are here. In short, your services will need to be on the same VPC as the Cloud SQL instances.
Is it possible to set up manual backup as per customer requirements?
You can configure backups using the SQL Admin API.
Please, let me list your questions along with their response:

-According to the documentation [1], the configuration is made up of a primary instance (master) in the primary zone and a failover replica in the secondary zone, at the moment is not possible the HA for Cloud SQL across regions.
All the microservices should be using private ip to do actions on this MySQL. How do set this up?
-You can set up a cloud SQL instance to use private IP, please review the next information, you may find it helpful [2].
Is there any native support from MySQL to enable Active replication to another region?
-I would recommend to get in contact with mysql support [3], so that you get the help you need, in the meantime you could review the next link [4], and see if this fits your needs.
Is it possible to set up manual backup as per customer requirements? I do understand automatic backup available.To meet RPO RTO requirements want to customize db backup frequency - is that possible?
-You can create a backing up on demand, please review the next link [5] which helps to illustrate how to set this kind of backups.
Please let me know if this information helps to address your questions.

We're implementing a slackbot internally in our company.
Because we cannot open a local server on internet, we want to bypass interactive message system.
Is there any way to do so ? A custom event for example ?
Thanks,
Yohann.
No, that is not possible.
And frankly, you can not use much of Slack's functionality without exposing your app to the Internet, so that Slack can interact with it.
But there are ways to expose your app to the Internet, without compromising the security of your company network. One way is to use a secure tunnel to your "localhost". A service provided by companies like ngrok.

Here is the situation.
We have an Oracle 11g database where one schema user has a private database link to a remote database. When the user initiates a certain process, it pulls a large amount of data across and slows down the other applications. We would like to limit when this user can access this remote database by disabling the database link during certain times of the day and then enable it when performance is not an issue.
I have not been able to find a way short of locking the user or dropping the database link to do this. Changing the open_links system parameter, I believe, requires a restart and that affects the other database links as well.
Does anyone have a clever way to implement this kind of restriction?
Thank you in advance.
Yes, Solution is to enable Resource Manger. Limit the CPU or RAM as per your requirement.
You can enable 2 profiles , one with more cpu/RAM/IO and other with less resources and enable them as per your requirement.

i'm configuring Standard Geo Replication for our Azure SQL database and need to validate Disaster recovery, but still have couple doubts and cannot find more details:)
I configured Standard Geo Replication and added Secondary database.
If i want to do DR Drill, i can just stop replication, make the second database as primary and re-point my ASP.NET applications to the new database server. Just change SQL server name.
My questions are:
What if Microsoft has some issues with data center, do they automatically just re-points DNS from main SQL to secondary so i don't need to do anything, and it would be done silently and everything would work, without my change?
I was trying to find out, if there is some kind of notification, that i can configure if SQL has an issue and i can stop replication and do this process by myself. Or will microsoft somehow notify us? email,... or only SQL AZURE dashboard?
What could be the case, that i need to do DR manually? Main SQL would stop working and AZURE cannot take care of that because...?
thanks a lot for your answers
Rado
We had this issues recently, we did not receive any email's or notification.
Luckily only SQL-Azure was affected. Hence we stopped the replication and updated connection string to point to secondary.
No they do not automatically re-point DNS from primary to secondary for databases
We have external services that keeps track of our systems and notifies us when things are not right.
We had to do a manual DR.
Would love to know if any one has a workflow in place to automate it or point to the right direction.
Hope that helps.
I am looking into different ways to handle updating an ASP.NET application across many different clients, and looking for suggestions from your previous experience.
We need the client apps to check if they have any available updates.
A way to Auto update (If possible, something similar to chromes but for webapp).
Some way to check that we are the ones sending the updates. (Checksum of some sort I would guess)
Any other tips/advice
Thanks
Edit: after thinking more about this overnight, I would have to agree that auto updates may not be the best. However maybe something more along the lines of how wordpress does it. Wordpress will display saying that there is an update available then clicking will auto update the system.
I would absolutely not have your application auto update on clients (assuming you mean clients are entities external to your organization) servers. We would immediately stop using a product that would "phone home" and update itself. Clients need to be able to choose when and how an update on their server occurs.
If you are going to do this, the easiest way would be to set up URI the systems could ping once a day etc. and see if there are updates available. If so the application would pull it down from the host system and update itself. If you do it using SSL then the certificate would verify the URI being hit is your company.
Having a hard time figuring out if you're actually talking about a web application or a desktop application. If you're trying to do something similar to Chrome...I'm guessing a desktop application. If that's the case...check out ClickOnce deployment.
It offers the first three bullet points you mention:
Every time a person runs the app, it will check for updates.
If updates are found, the user can choose to install them or not (better user experience than forcing the update on the user).
The application always checks the URL that the app was installed from...which in your case would be your servers.
