Great Eductional Video! Have you posted or planning to post a video on how to use AWS Schema Conversion Tool (SCT) or Database Migration Service (DMS) to move data in case the system has zero downtime requirement? Datapump migration will always include some downtime with production system because you have to shutdown the on-premise system, move the data pump file to AWS and then import file and test everything and then switch users to AWS RDS instance. If the datapump files are too big (TB), we have to use snowball service from amazon to send us storage device and ship it to them so they can upload it to S3. This process can take several days.

Hello Moe, thanks for your interest. I have mentioned all of the options to migrate - expdp/impdp with downtime, AWS DMS with lesser downtime and GG replication without downtime. I will cover these topics on future videos for sure. I have not done my research on SCT yet.

Great Video! If I want to migrate an oracle 19c datrabase from one source RDS which has 30 schemas to another Oracle RDS in another account, do I need to do one schema at a time or there is a way to export/import all 30 schemas together using DBMS_DATAPUMP?

@YouVolve

Жыл бұрын

Hi Tony, you can export all the 30 schemas together. Once you define the handle (v_hndl in the example below) for the job, you can add the metadata filter as below to include the schemas you want: DBMS_DATAPUMP.METADATA_FILTER(v_hdnl,'SCHEMA_EXPR','IN (''SCHEMA1'',''SCHEMA2'')');

Great Informational Video! My understanding is that RDS can only support one oracle database and one standalone instance. If you have multiple 3 oracle databases/instances running on the on-premise server, do you create 3 RDS instances or do you add the all the databases as separate schemas into the main single RDS instance?

@YouVolve

Жыл бұрын

You may migrate the 3 on-premise databases to 3 individual RDS instances, or 3 PDBs in one container database or 3 individual schemas in a single RDS instance. The 3rd option is cost effective as it will need only one license.

@moedweik9523

Жыл бұрын

@@YouVolve Yes, but does not the 3rd option may cause performance and security problems too because you have all 3 databases using one oracle instance (memory resources and same oracle processes) versus one instance per database on premise? If we size up the RDS to more CPU then we need more licenses. According to AWS too, RDS will only support one container and one PDB (not multiple). You will also have a single point of failure so if the instance fails all 3 databases will be down.

@YouVolve

Жыл бұрын

Hello Moe, you are in the best position to decide on the options... and yes, you are right, I have overlooked the PDB limits currently in RDS. For smaller and logically related databases, consolidation is good as you can still maintain the security and resource allocation using proper grants and resource manager plans.

Can we use Oracle Data Guard between on prem oracle 19c and AWS RDS Instance ? If yes .. any guidance how pls ?

@YouVolve

@anuragbishnoi - Thanks for your watching my video and the question. Oracle Data Guard cannot be setup between an on-premise database and an RDS instance. RDS is pretty much self-managed database and as I explained in my videos, many of the DBA activities, even login with SYS or with SYSTEM users etc are not allowed. However, Data Guard can be setup between an on-prem Oracle database and an Oracle database hosted in an AWS EC2 server. For RDS migration purpose, you may use Data Pump export, Golden Gate replication or AWS DMS etc.

You can definitely create DB links between two RDS DBs or between RDS and on-premise as long as the VPC has been setup and network rules have set properly.

Excellent Video! Does this method work for a 100 GB - 200 GB on-premise database or not? I think database pump will compress the data but S3 might have size limit of 5 GB. I also need large local storage on my laptop to download from server and then upload to S3.

@YouVolve

Thanks for your question. Yes it will definitely work. You have to allocate storage as per your requirement and also keep the storage auto-scaling on to a maximum limit that you think reasonable. I have explained this in the my previous video on creating the RDS instance. Also, as I mentioned in this video, it is possible to mount an S3 bucket as a file system to the source server and you can directly upload the dumps to S3 if this arrangement is in place. Downloading to your local storage takes time and also requires large storage so not suggested for large uploads. Up to around 300GB it should be okay.

@YouVolve

@karunberi - yes, if your RDS instance is not open to the internet, then you must open the ports and allow traffic between the RDS and on-prem computers by configuring your network/firewall rules. This is usually done by your organization's network security teams and not by DBAs. Also, you have to create/configure the Security Groups under the AWS account. AWS documentations are very elaborate on this and you should be able to do it by going through the documents.

For your degree project, you don't have to go through the corporate level security measures. You may create a free AWS account for educational purpose and create an internet accessible RDS instance which, I believe, is accessible for 30 days and has some restriction. Once your RDS instance is accessible, you can migrate your on-prem database to AWS using the method I have demonstrated in the video.

Yes, you can do all the steps that involve execution of SQL or PL/SQL code in SQL developer, SQL Plus or any SQL net client like Toad. Please note that for RDS instances, you won't have access to the Operating System or the host. Also, you cannot login to the DB using SYS or SYSTEM account.

To download the log files to your local machine to read it in a traditional way, you have to do exactly opposite of what you do while transferring the dumps to RDS host. So, once your log is generated in the RDS host in a location pointed to by the DATA_PUMP_DIR object, you will first use rdsadmin_s3_tasks.upload_to_s3 package to upload the log to the S3 bucket and then from S3 bucket you have to download that to your local machine.
