Why the tables content is not updated if the aws database connection is successfull - aws-lambda

I launched my database in EC2 and my web-service is running locally.
The cloud-watch shows a successful database connection. But the table content information is not able to retrieve properly and it doesn't show any error message.
How can I fix this?

Try to connect database from local machine with native database tool and run the sql to check if you can see the content of the table in sql prompt or how fast the data can fetch.

Informatica Workflow Cannot create proper Relational connection object to connect to SQL Server

On my Infa server PC, in Informatica Administration I created a repository service giving Oracle Database information. Once in Informatica I connect to this repository and there I want to create a mapping importing a table from a remote sql server pc (on my home network domain) and then create a workflow to put the data into an oracle target table.
Using ODBC admin console I created and tested the connection and I am also able to telnet the linked sql server and port.
Within informatica I created a relational connection for sql server and when I run the workflow I get the error reason (14007) failed to create and inituiate OLE DB instance and datatabase driven error, failed to connect to database using user I use in SSMS for windows authentication and connection string(). I would like to know, first of of all, if I am doing something wrong, willing to connect me to a repository with oracle database information and then use a sql server table on remote pc. Do I have to create another repository for Sql server and there use sql server tables or I can mix them? secondly I would like to know how to create a relational connection object in informatica for my linked sql server so that it will be the same of relatonal connection created with ODBC admin consolle. Last but not least I would like to understand why gives an error out saying I left connection string empty, when I cannot see a place where I can put it by creating the relational connection object
I might not be able to solve the problem completely, but here's few remarks that might be helpful:
PowerCenter Repository database is where PowerCenter will store all the metadata about the processes you create. It may be Oracle - that's perfectly fine. And as it is not releated to your data sources or targets, you do not need to create another one for different sources/targets. One is enough for all ot them.
Using PowerCenter Workflow Manager create the appropriate connections to all the systems you need. Here you create the connections that indicate ODBC/other connections that will be used by Integration Service to actually connect to your data sources and targets, hence
Make sure the ODBC / other data sources are specified on Intergration Service. It is the IS that will run the process, connect to systems specified in the process with the defined connections.
When you build the mappings, you create them in a client app (Mapping Designer) and you can connect to DB engines to create source and target definitions. Mark, that in such case you use the connection (eg. ODBC data source) defined on the client. Once you will try to actually run the workflow with the given mapping, it is executed on IS (mentioned above) where appropriate connections need to be defined - and that's completely separate.
When editing a session in a workflow, for each source and target you need to pick a connection defined in Informatica Repository, created as described in point 2 above (or use a variable to indicate one - but that's another story)
So the error you mention seems to be related to connection created in Workflow Manager - it probably does not specify the connection string that should refer the data source defined on IS.

Oracle sql or pl/sql command for checking if remote database is available i.e. similar to OS command tnsping

In my PL/SQL script, I have requirement to test the connectivity of remote data. Normally, in OS shell, we use command tnsping. Is there any command in SQL or PL/SQL so that I can test connectivity.
Basically, I am getting some data using database link. I want my script to execute immediately. If remote database is available then I want to run query using database link. If remote database is unavailable then I want to skip the getting of data using database link. So, this is the reason why I am looking for.
Kindly guide me for proper way. So, that my script does not hang in case of unavailability of remote database.
I am using Oracle 12.1C.

How do I connect to oracle apex database through JDBC?

I have got a workspace in apex.oracle.com , Now , I want to connect to that database through JDBC from ubuntu-14.04 machine. please explain the steps , From where should I download the drivers and what should be the arguments in
DriverManager.getConnection();
step by step please. Thank you
You will not be able to connect to the database that's supporting the APEX instance on apex.oracle.com. If you are hosting your own instance, it's no different than connecting to any other Oracle database.A quick code snippet can be found here: http://www.java2s.com/Code/Java/Database-SQL-JDBC/TestOracleJDBCDriverInstallation.htm. You will need a password for the user/schema that you wish to connect to. If you don't have one, then talk to your DBA.
BTW, please remember that no production-type application and data should be used on the public APEX instance.
Maybe your problem is (or was) that you cannot connect via JDBC using the users you administered in your APEX workspace.
It seems to me that APEX users are not regular users for DB connections via JDBC. If my assumption is right, then you need to create database user with sufficient privileges to access the workspace tables.
