Re: How to error check for wrong Admin MSP certificate on network #fabric #docker #fabric-ca

Gari Singh <garis@...>
 

BatchSize actually falls under the Orderer group and not the Application group.
Therefore, you need a majority of the orderer admins to sign the config update.
Given you state this is a simple network, I'll assume you only have a single orderer org, so you just need to sign the config update using an orderer admin identity.

Subject: [EXTERNAL] [Hyperledger Fabric] How to error check for wrong Admin MSP certificate on network #fabric #docker #fabric-ca

Hi all,

I have the most simple fabric-network, and wanted to make a simple channel-config update of the batchsize (https://hyperledger-fabric.readthedocs.io/en/release-1.4/config_update.html)

Everything is fine, until I want to post the modified config to the orderer/network, then I receive the following error inside CLI container, as peer0.org1 adm:



Orderer log:




So according to google-searches, I found this topic which states that there migth be two possible reasons (https://stackoverflow.com/questions/57662562/when-i-try-to-create-a-channel-using-hyperledger-fabric-the-request-fails)
- the MSP ID that was passed as a parameter with the request was not recognized by the ordering service
- If you are updating an application channel, this error could occur if your organization is not yet a member of the channel you are trying to update

The Org1 is indeed part of the channel already, as it created and joined the channel with the bootstrap:






So then I expect the issue to be a mismatch between MSP-ID somewhere. The topic of certificates are somewhat new to me, can anybody guide me in direction of error checking this myself, which files should I compare to see what MSP-file is wrong?

This is the cert-file inside the CLI container for peer0.org1 admin:



This is the Admin-file on the host machine:



CA-related info for Org1:




This is the policy settings inside the channel-config block:



Thanks for any input that can help me compare the rigth certificates, to spot the wrong one and why it is wrong.

Re: Performance Improvement: Max number of assets and max size of payload in single Transaction?

David Enyeart
 

On the other hand, large numbers of tiny transactions will not be as efficient due to the per-transaction overhead. It is quite typical to batch multiple writes into a single transaction (e.g. 100 at a time), especially upon initial ledger population. This provides a good balance between efficiency and keeping the transactions and blocks at reasonable sizes for distribution around the network. Some empirical trials will help you to find the sweet spot for your specific workload and data sizes.

The number of assets in a single transaction depends on several factors, e.g., the key-value size.

Putting many large data in one transaction may consume heavy CPU and memory at the peer, and hang other operations for a long time.

And large blocks are not efficient to distribute in the network.

This is a typical high-performance scenario, and assigning more hardware resource can accelerate the process.

    Given there is some additional overhead included in the Fabric protocol layer, you are looking at a max payload in terms of your keys/value of ~90MB (to be on the safe side).

    I'll assume that your chaincode is designed to insert multiple asset records for a single invoke.

    Hello Experts,

    I have some concerns about number of assets and size of the payload in a single transaction.

    1)  How big payload in terms of size, we can add in a single transaction in Hyperledger Fabric. I have millions of assets, ingesting into Fabric network. Maximum assets(Key-Value) can be added into the single transaction are 1000(Correct if I am wrong). Can we customize this number, so that a high number of an asset can be added in a single transaction?

    2) What is an efficient way to trigger a huge number of assets into the network?

    Currently, I could add only 100 assets in a single transaction.

    I am trying to improve performance in terms of TPS and latency. I have already added necessary indexes and composite key (Couch DB)

    Thank you.

[common.deliver] deliverBlocks -> DEBU 371 Rejecting deliver for X.X.X.X:42926 because channel tracktrace not found

Siddharth Jain
 

we have a network that runs fine without Docker but when we try to containerize it we get this error in orderer logs:

2020-02-13 22:19:16.706 UTC [common.deliver] deliverBlocks -> DEBU 371 Rejecting deliver for X.X.X.X:42926 because channel tracktrace not found

we can actually see the channel if we look inside the orderer

root@a60672f8b829:/home# ls /var/hyperledger/production/chains
foo  tracktrace

we have mounted the orderer directory (when it was running without Docker) to /var/hyperledger/production

anyone know what's going on here and how to fix this? thanks

If you're using the new lifecycle commands, the chaincode package is a gzip compressed tar; if you're using the legacy (lscc) commands, the package is a protobuf encoded chaincode deployment spec. You'll need to unmarshal that message to get to the code package tar file.

Re: Modify Chain code container

Matthew Sykes
 

The peer does not "fire the docker run cmd" but uses the docker API to create and start the container.


If you want to expose a port, you can either modify the fabric code or create your own base image for chaincode that exposes the port. If you create your own image, you only need to configure the peer(s) to use your image instead of the fabric image (peer.chaincode.${language}).
