use the sql Service Broker.
basically you subscribe to a query, so when your table is updated the server sends a notification of a change to you.

Right now i'm working with oracle 11g on windows and currently trying to send notifications from my database using emails (Gmail), but all I'm clear with right now is that I have to include the Gmail certificate in the oracle wallets but don't know how to do it, and I also think that there's something to be done with the access control lists but I'm not completley sure how, any help or recommendations are enormously appreciated.
Backup the Oracle wallet files first. To get he wallet file locations run:
SELECT * FROM V$ENCRYPTION_WALLET
Then look at the orapki utility to get you started - search for this and you should find the Oracle documentation.
The following is how to add a certificate to the wallet:
orapki wallet add -wallet wallet_location -trusted_cert -cert certificate_location
For any Windows users who may need help with what I asked, there's a really good link/tutorial sort of instruction set on git:
https://github.com/YairPR/Oracle/wiki/Enviar-correo-con-Oracle:--ACL---UTL_SMTP---Wallet---SSL--TLS----Gmail
It's in spanish, but all the commands and steps are there, although you may just happen to need to translate it, hope it's useful for someone!
Does anyone know when the getSchema function is called, or what calls it?
For that matter does anyone know of any documentation that outlines the flow between the Google Data Studio Connector functions.
So I think I can answer my own question, but if anyone can add any clarification that would still be welcome.
It appears that this function provides the full list of connector fields, specifically when the connector is connected to a data source.
It may be called at other points as well which where some further clarification would be useful.
getSchema() is called by Data Studio when Data Studio needs to know the schema. This usually happens 1) right after you complete the configuration for a community connector or 2) when you are editing a data source in Data Studio and reconnect to it.
We are using mssql node.js package to updating the values in Database.we are update too more values at same times.Sometimes we faced the below error.Could you please provide a better solution to resolve that?
This error suggests that your database is taking too long to respond. Either add some retry logic (Polly JS is good for that sort of thing) or have a look at why the updates to the database are taking so long (looking at the execution plan should help with that).
I am connecting to an oracle DB from a JAVA code which in turn is called from a JSP page. But i am confused as to whether a normal configuration/properties file is the best place to store the connection details to the DB.
Apologies if this sounds too silly.
Thanks in Advance
Thanks all for the Responses,
I went ahead with the Data sources and was able to do it successfully in my scenario :)
Appreciate all the help.
I was wondering if it is possible to create a SSIS package that would take all inserts and updates that were done to the specific table in SQL Server and write them into a text file.
I watched some videos on youtube but I couldn't find this specific case.
Could anyone guide me please?
Have you looked into Change Data Capture (CDC)? It's pretty fantastic.
