我正在尝试Hyperledger Composer v0.16.0.根据这个过程,我想在云上部署BNA到Fabric网络.但发生以下错误.请告诉我如何解决它.

命令:

composer network start --card PeerAdmin@myfabric --networkAdmin admin --networkAdminEnrollSecret adminpw --archiveFile trade-network.bna --file networkadmin.card

结果:

tarting business network from archive: trade-network.bna
Business network definition:
    Identifier: trade-network@0.1.13
    Description: Commodities Trading Business Network

Processing these Network Admins: 
    userName: admin

? Starting business network definition. This may take a minute...

我从该站点了解到，频道中的每个成员可以具有多个锚点对等点，以防止SPOF。

我想在fabcar-demo中尝试多个锚点同位体。

请让我知道如何配置多个锚点对等点。

我用BYFN将认可政策从"OR"改为"AND" 并实例化了Chaincode.但是,即使在执行Invoke之后,分类帐中的数据也不会更改.我确认"OR"条件正在运行.(分类帐中的数据已更改)

请告诉我如何解决它.

peer chaincode instantiate -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "**OR** ('Org1MSP.member','Org2MSP.member')"
