How to connect Oracle Storage account in arcserver

 How to connect Oracle Storage account in arcserver?

When I tried to connect OCI Object storage with arcserver, I am getting an error saying failed to connect.

I tried the same credentials with Cloudberry and I encounter an error. But in cloudberry the error shows the reason. Fix for the error is http://www.linuxblackmagic.com/2021/10/authorization-mechanism-you-have.html

After fixing the error, I came to know that the issue is related to "Signature Version". For changing the signature version, there is no option in web. We need to go to "C:\Program Files\Arcserve\Unified Data Protection\Management\BIN\CCI\Config"

then open the file "AmazonPlugin", change the line from true to false

# original

#Set S3SignerType Override to true

SIGNER_OVERRIDE=true


#after change

#Set S3SignerType Override to true

SIGNER_OVERRIDE=false

Then restart the arcserver.

Try to connect, your OCI object storage account will connect now.



Authorization mechanism you have provided is not supported. please use aws4-hmac-sha256

 When you work with AWS SDK or AWS S3 compatible storage, during the time of connection settings you may encounter this error 

authorization mechanism you have provided is not supported. please use aws4-hmac-sha256

I got this error when I tried to add a storage in Cloudberry tool. The destination is Oracle Object storage.

How to solve this error?

This is because of the signature version used is old. You need to Click on the "Advanced Settings", then on drop down of Signature version, choose 4.
