I am new to CORDA blockchain, and i would like to know the possibilities of Storing the corda states/vault in NoSQL DBs like Elasticsearch or Cassandra. Or can we put the vault data to ActiveMQ?
Supported databases:
Open Source Edition: H2, PostgreSQL, and SQL Server (untested).
Source: https://docs.corda.net/node-database.html
Enterprise Edition: Azure SQL, SQL Server, Oracle, and PostgreSQL.

In our project we are implementing Javers to records audits in Oracle , and looking for any API support to migrate audit data from Oracle to PostgreSQL or to Mongo as we need to migrate from oracle to other database in near future.
Please advise
I'm currently trying to test a JDBC connection to SAP Hana with AWS Glue.
Testing the connection results in the following error message:
com.amazonaws.glue.jobexecutor.commands.exception.CommandExecutorException: java.lang.IllegalArgumentException: No enum constant com.amazonaws.glue.jobexecutor.commands.jdbc.SupportedDriver.SAP
My JDBC URL looks like that jdbc:sap://ip:port/?databaseName=tdb
After looking in the developer guide from AWS for the JDBC Connection Properties, it looks like that required protocol for hana is not a supported right now.
So is this the case that you currently can't connect to a SAP Hana database with AWS Glue or am I missing something in my connection configuration?
The HANA JDBC driver seems not to be supported at the moment. AWS describes a way via S3, that, depending on your requirements might be enough for you:

I would like to use an open source version of kafka-connect instead of the confluent one as it appears that confluent cli is not for production and only for dev. I would like to be able to listen to changes on mysql database on aws ec2. Can someone point me in the right direction.
Kafka Connect is part of Apache Kafka. Period. If you want to use Kafka Connect you can do so with any modern distribution of Apache Kafka.
You then need a connector plugin to use with Kafka Connect, specific to your source technology. For integrating with a database there are various considerations, and available for MySQL you specifically have:
Kafka Connect JDBC - see it in action here
Debezium - see it in action here
The Confluent CLI is just a tool for helping manage and deploy Confluent Platform on developer machines. Confluent Platform itself is widely used in production.
I have database username and password to access oracle db and also have service url like https://X-X.X.X.oraclecloudapps.com/apex/.
Can anybody know how to connect this db using JDBC connection.
I tried using oracle thin driver but somehow it failes.
Sample java code:
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:#//X.X.X.X.oraclecloudapps.com:1521/sid", "username", "****");
It throws
Exception in thread "main" java.sql.SQLRecoverableException: Io exception: The Network Adapter could not establish the connection
I don't know SID here, it would be helpful if anybody give steps to find SID/ServiceName from Oracle Cloud dashboard.
You can't use JDBC to connect to the Database Schema Service. You can connect using the API or tools that utilize the REST API. For data upload to Oracle Database Schema Service, use Oracle SQL Developer, the Oracle Application Express SQL Workshop Data Upload Utility or the Oracle Application Express Data Load utility. Read more here: http://docs.oracle.com/cloud/latest/dbcs_schema/CSDBU/GUID-3B14CF7A-637B-4019-AAA7-A6DC5FF3D2AE.htm#CSDBU177
There is only three way to connect Database Schema Service.
From an Oracle Application Express application running in Database Schema Service
From a Java application running in an Oracle Java Cloud Service
Through RESTful Web services
Try the following JDBC URL to resolve the issue
"jdbc:oracle:thin:#host-address:1521/sid";

I want to expose Oracle database data with an Odata endpoint.I tried using JayData server on node.js but it currently supports only mongo db but not oracle.So before I start trying connecting Oracle with Apache Olingo I would like to know if someone has already been this path.Please advise
