It is also possible to replicate all the changes from the source database to keep the data on the target database synchronized with the source until the final cut over to minimize downtime needed for the migration process.

AWS Database Migration Service (DMS)ĪWS DMS allows you to copy full schemas from the source to the target database. Migration Methods for Amazon RDSĪs Amazon RDS doesn’t provide access to the operating system of the database server, the database migration options are mostly the ones that can be achieved using SQL*Net connections. In this case, the migration is between similar platforms with the same endian formats. Oracle databases on Oracle cloud run Oracle Linux. Most of those run on Linux operating systems. Amazon EC2 (Elastic Compute): a compute instance on which you control and conventionally administer your Oracle database.Amazon RDS (Relational Database Service): a managed database service, where you don’t have access to the physical database server, but connect to the database instance directly using SQL*Net connections.There are two different Oracle database implementations on AWS: Benefit from the best price-performance for Oracle databases on the public cloud.Run your workload on Oracle Autonomous Database and benefit from fully automated backups, patching, upgrade, high availability, and disaster recovery.Deploy Oracle databases on Exadata for high performance and mission-critical workloads.Deploy and use all features and options of Oracle database, including Real Application Clusters (RAC) for high availability and scalability.Deploy the latest versions of Oracle databases.Summarized in one sentence: Oracle Cloud Infrastructure is the best cloud platform on which to run your Oracle workloads! Why to move to the Oracle cloud? Have a look at part 1 highlighting the benefits of the Oracle cloud. In this part, we will deal with migrating Oracle databases running on Amazon Web Services (AWS) to Oracle cloud.
#Aws oracle database how to
This is why I want to access it and if I find something suspicious then modify it.In previous parts, we discussed how to move Oracle databases from on-premise to Oracle Cloud. Most of the answers I've found refer to the tnsnames.ora as the place where the service names and sids are configured and therefore includes information on how to actually form a connection string. I am using this jdbc URL: also tried using this format apparently the AWS RDS instance is not configured with service names. Executing these from a SQL command prompt produces no errors. Queries like the following are successfully executed: SELECT COUNT(*) FROM (ĭISTINCT tab.column_a, tab.column_a AS L0, tab.column_a AS L1, tab.column_a AS L2Īnd by fail I mean producing the error I mentioned above. This error does not even seem to be consistent since for example some queries do work.Īdding more info after reading some comments: The problem is that AWS does NOT allow remote access to the Oracle RDS and I cannot find anything in the AWS console which would help me change or even access the contents of the tnsnames.ora.Ĭan I maybe do it using SQL? I'm at my wits end here. TNS:listener does not currently know of SID given in connect descriptor.How to Fix 'ORA-12505, TNS:listener does not currently know of SID given in connect descriptor'.Which is directly connected these two following resolutions ORA-12505, TNS:listener does not currently know of SID given in connect descriptor I have an Oracle RDS instance running on AWS and I need to access the tnsnames.ora file and check its configuration since I am getting this error Caused by: .NetException: Listener refused the connection with the following error:
