I'm trying to explore Oracle cloud's autonomous blockchain service to deploy a Hyperledger composer business network.
Oracle's Blockchain service uses Hyperledger Fabric as the backbone but I faced issues deploying the network to it.
Has anyone used Hyperledger Composer with Oracle's blockchain service. Does it support composer networks?
To answer your question, the answer is yes. Since they are based on the same fabric, as long as the versions are compatible, you can use the composer with OBCS.

I have a blockchain business network setup on hyperledger composer which interacts with Hyperledger Fabric. My business network is then exposed as a REST server which my angular application interacts with.
Im just wondering what is the best way to setup decetralised login functionality to my angular application?
I am getting started with the Hyperledger fabric network. I went through the examples of setting up single org setup on a single node and Single Org-Multi Node as well.
I am now trying to setup a Multi-Org, Multi Node network and the all the examples I have seen online, uses Hyperledger Composer. So, Is Composer mandatory to setup HYL-Fabric Multi-node, Multi-Org structrure, If not, can anyone provide me with the steps needed to setup a n/w without the composer?
Thanks
I wanted to deployed and configured a Hyperledger network locally and also transfer it to Azure Hyperledger-Fabric for single organisation.
this may help https://hyperledger.github.io/composer/latest/tutorials/deploy-to-fabric-single-org - Hyperledger Composer has a single-org tutorial. However, to learn about Fabric itself, you should look at the Fabric network samples (easy to find on the web)
Is it possible to measure Hyperledger composer network performance which runs on Hyperledger fabric using Hyperledger Caliper framework?
If yes can you guide me how can I change the configuration to connect Caliper to running Hyperledger composer network?
Hyperledger Caliper is a blockchain benchmark framework to measure performance of multiple blockchain solutions.
I think the below links help you a lot.

If you use composer rest server to enable rest api endpoints, you can always use apache meter to test out the latency of your system.
I have recently deployed and started a business-network with Hyperledger Composer, I have only one peer (?) in which I have created the network and now I am using the rest-server for adding participant and doing transaction from an Android app to my personal blockchain and everything goes well.
So...Need I to configure one or more peers on my network? What's the utility of doing that?
I know that other blockchains needs a lot of peers for co-validating transactions and for maintaining a big scalability / distributed data; doesn't Hyperledger do it for me without adding more peers in my network?
If you have started with Hyperledger Composer you are probably using the 'standard' development Fabric with a Single Peer. This is a 'minimal' Fabric provided to get developers a fast start without the need to configure and deploy a Fabric. But you are correct Hyperleder Fabric can be configured for Multi Peer Multi Organisation distributed ledgers.
There are tutorials in the Fabric documentation for setting up a Fabric from scratch, and also this document covers a tool for extending the Fabric.
