Thanks for the nice comments. We have videos on creating RAC database on AWS. Since AWS RDS doesn't support RAC, rather they support Multi AZ, so the RAC setup needs to be done on EC2 server. And migrating to any database hosted on EC2 server is similar to migrating to any on premise server or VM
Hi is it possible to automate the process. My use case is I will have oracle dump file in S3 and I will need to select some tables fro the dump file and store it back to s3 and then transform and abck to s3 then read using Athena ... In this process I assume we can selectively import tables using INCLUDE/EXCLUDE into a RDS Oracle instance and then store files form RDS instance into S3 as csv/parquet using an ETL tool ... This is a weekly load and each time we will get full data dump, so i believe once I write data in s3 as csv will need to drop the tables form the RDS. Can you please guide with an overall approach?
Excellent Video! Would this work too for 200GB- 300 GB oracle dump file created on RHEL server? Do I need 300 GB of local disk space on my laptop and 300 GB of S3 storage? It seems you are moving the file from on-premise server to local windows machine and then upload to AWS S3.
Glad you liked it. Yes it will work for the size you mentioned. We had to transfer to local windows since the VM used here couldn't communicate with the outer world. You can send it directly to S3 with aws cli enabled server. Or send to any jump server having more than 300gb of space before transferring to S3
Thanks for the comments. For exporting schemas/tablespaces from rds, the procedure would be the same, just a change in datapump syntax. You can refer to the below link for syntax docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Oracle.Procedural.Importing.html#Oracle.Procedural.Importing.DataPumpDBLink.Step6 The syntax is : DECLARE v_hdnl NUMBER; BEGIN v_hdnl := DBMS_DATAPUMP.OPEN( operation => 'EXPORT', job_mode => 'SCHEMA', job_name=>null); DBMS_DATAPUMP.ADD_FILE( handle => v_hdnl, filename => 'sample.dmp', directory => 'DATA_PUMP_DIR', filetype => dbms_datapump.ku$_file_type_dump_file); DBMS_DATAPUMP.ADD_FILE( handle => v_hdnl, filename => 'sample_exp.log', directory => 'DATA_PUMP_DIR', filetype => dbms_datapump.ku$_file_type_log_file); DBMS_DATAPUMP.METADATA_FILTER(v_hdnl,'SCHEMA_EXPR','IN (''SCHEMA_1'')'); DBMS_DATAPUMP.START_JOB(v_hdnl); END; /
Thanks a lot! Rather than using PL/SQL Procedures and packages, is there any issue to migrate with datapump utility (expdp/impdp ) ? I chose impdp. Your comments please.
Thought we have already replied so. So a delay in responding. How will you use impdp in RDS other than PL/SQL Procedures and Packages, when you donot have login to the DB server. To use impdp, we need access to the DB server right?
@@InfraXpertzz thanks for the reply. We have one option that we can create oracle client on remote machine windows/Linux and we can use datapump utility and sqlplus and other utilities. and I have done DB import of 1tb using datapump on my 18c RDS.
Nice video and good explanation. I have a question - can we use datapump to import csv data files?I have a usecase where data is present in csv and want to upload it to RDS, can this be done using RDS-S3 integration and datapump?
Really very good explanation and thanks a lot. One doubt, is there any limitation for s3 storage for transferting dump. If dump size is more, how to do speedup and additional storage in s3.
Thanks a lot for the nice comments. I am not aware of any limitations though. Still if you are planning to work on this in your project environment, I would request you to raise a case with AWS to get more details
If you are on corporate network dont you have to open firewall for port 1521 to RDS endpoint or IP address so your SQL Developer client can connect to AWS RDS service using 1521?
@@InfraXpertzzIt might take security a few weeks to open up port 1521 on corporate firewall. Do you know if there is way to connect to RDS using sql*plus client on the same machine where RDS instance runs so i can execute the SQL commands to run Data Pump?
The problem with using EC2 for connection to RDS is that AWS will charge extra money for the EC2 instance. The port 1521 is open in the security group attached to the RDS. I even tested access using port 1521 from home compute and it did not work. When i run TRACEROUTE I do see traffic leaving the the local network to AWS servers but then i start seeing timeouts.
Can you explain how did your local oracle SQL Developer running on your local machine connect to the Oracle Database in AWS/RDS? Also dont you have to create an oracle instance in AWS and link it to RDS before you do this migration?
With rds credentials and connectivity details you can connect from local sql developer. Plz check the full video to have an understanding. Rds is a database. There is no need to create any oracle instance separately in AWS
@@InfraXpertzz My thinking is RDS is relational database service that can support mysql, sql server, oracle, etc. I saw another video where they created an oracle instance using RDS. Also, are you connecting from your local site SQL developer to AWS using VPN connection and port 1521?
I want to transfer just a few tables to S3 only and stop. And this should happen on a schedule automatically. After that another team will take care of the S3 data. Is that possible? Without RDS in the picture
Yes. Its there. You can check from the playlist. It is from oracle to mysql. This is a demo shown in test environment. In real life you might encounter more issues while converting, which needs to be handled
Hi , Can you do me a favor please, I have been tryng modify a init parameter in aws rds with command ALTER SYSTEM SET pga_aggregate_limit=0 SCOPE=BOTH; but unable to run it. Can you please help me with aws rds relevant command to modify the same parameter, its little urgent, thanks
most of the parameters you need to change from parameter groups itself from RDS console. However I will check and let you know if this is feasible or not. One more thing I noticed, that the pga_aggregate_limit parameter is a static one in AWS. If you go to Parameter group and search for pga, you will see the apply type as static. So scope=both wont work in here.

If you are on corporate network dont you have to open firewall for port 1521 to RDS endpoint or IP address so your SQL Developer client can connect to AWS RDS service using 1521?
Yes you have to. Also in aws security group the port needs to be opened in whichever network you are
@@InfraXpertzzIt might take security a few weeks to open up port 1521 on corporate firewall. Do you know if there is way to connect to RDS using sql*plus client on the same machine where RDS instance runs so i can execute the SQL commands to run Data Pump?
If from aws security group the port 1521 is opened, you can create an ec2 instance, install oracle client over there and connect using sqlplus
The problem with using EC2 for connection to RDS is that AWS will charge extra money for the EC2 instance. The port 1521 is open in the security group attached to the RDS. I even tested access using port 1521 from home compute and it did not work. When i run TRACEROUTE I do see traffic leaving the the local network to AWS servers but then i start seeing timeouts.

I want to transfer just a few tables to S3 only and stop. And this should happen on a schedule automatically. After that another team will take care of the S3 data.
Is that possible?
Without RDS in the picture
You can do this through dbms jib scheduler. Or even you can set a cronjob in ec2 to take the export through network link
Poderiam colocar legenda pelo penos em Ingles...a pronuncia é muito dificil
U can check the blog from the link provided in the video description
can this on prem oracle db be converted to AWS postgres via S3 integration?
Sorry. Need to check on that. Using dms and aws sct it is possible, but with s3 integration, we cannot comment much on it
@@InfraXpertzz cool, do you have a video/reference on aws sct and dms?
Yes. Its there. You can check from the playlist. It is from oracle to mysql. This is a demo shown in test environment. In real life you might encounter more issues while converting, which needs to be handled

Did u have to restart the database? As it can be seen as static parameter in the parameter group
@@InfraXpertzz yes as it’s static in aws, after changed it was showing pending reboot to effect, rebooted instance.
