在超级账本结构中动态执行交易时出错

Question

I have modified the fabcar example to execute in a particular time interval. It works fine upto 4th or 5th times. Then it start showing error like this.

2020-02-24T10:33:09.018Z - warn: [Query]: evaluate: Query ID "[object Object]" of peer "peer1.org1.example.com:8051" failed: message=cannot retrieve package for chaincode fabcar/1.0, error open /var/hyperledger/production/chaincodes/fabcar.1.0: no such file or directory, stack=Error: cannot retrieve package for chaincode fabcar/1.0, error open /var/hyperledger/production/chaincodes/fabcar.1.0: no such file or directory

Tried the answer from this link Querying chaincode is only successful in ~3/5 cases with nodejs . But I could not able to install the chaincode in peer1 through CLI container. Facing error like this.

Error: error getting endorser client for install: endorser client failed to connect to peer1.org1.example.com:7051: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp 172.23.0.11:7051: connect: connection refused"

How to resolve?

Answer 1

It has been cleared by installing chaincode in both the peers. Here I am giving code snippet to install the chaincode via ./startFabric.sh

Installation in peer1 0f Organisation 1

echo "Installing smart contract on peer1.org1.example.com"
docker exec \
  -e CORE_PEER_LOCALMSPID=Org1MSP \
  -e CORE_PEER_ADDRESS=peer1.org1.example.com:8051 \
  -e CORE_PEER_MSPCONFIGPATH=${ORG1_MSPCONFIGPATH} \
  -e CORE_PEER_TLS_ROOTCERT_FILE=${ORG1_TLS_ROOTCERT_FILE} \
  cli \
  peer chaincode install \
    -n fabcar \
    -v 1.0 \
    -p "$CC_SRC_PATH" \
    -l "$CC_RUNTIME_LANGUAGE"

Installation in peer1 of organisation 2

echo "Installing smart contract on peer1.org2.example.com"
docker exec \
  -e CORE_PEER_LOCALMSPID=Org2MSP \
  -e CORE_PEER_ADDRESS=peer1.org2.example.com:10051 \
  -e CORE_PEER_MSPCONFIGPATH=${ORG2_MSPCONFIGPATH} \
  -e CORE_PEER_TLS_ROOTCERT_FILE=${ORG2_TLS_ROOTCERT_FILE} \
  cli \
  peer chaincode install \
    -n fabcar \
    -v 1.0 \
    -p "$CC_SRC_PATH" \
    -l "$CC_RUNTIME_LANGUAGE"

In Invoke initLedger()

docker exec \
  -e CORE_PEER_LOCALMSPID=Org1MSP \
  -e CORE_PEER_MSPCONFIGPATH=${ORG1_MSPCONFIGPATH} \
  cli \
  peer chaincode invoke \
    -o orderer.example.com:7050 \
    -C mychannel \
    -n fabcar \
    -c '{"function":"initLedger","Args":[]}' \
    --waitForEvent \
    --tls \
    --cafile ${ORDERER_TLS_ROOTCERT_FILE} \
    --peerAddresses peer0.org1.example.com:7051 \
    --peerAddresses peer1.org1.example.com:8051 \
    --peerAddresses peer0.org2.example.com:9051 \
    --peerAddresses peer1.org2.example.com:10051 \
    --tlsRootCertFiles ${ORG1_TLS_ROOTCERT_FILE} \
    --tlsRootCertFiles ${ORG1_TLS_ROOTCERT_FILE} \
    --tlsRootCertFiles ${ORG2_TLS_ROOTCERT_FILE} \
    --tlsRootCertFiles ${ORG2_TLS_ROOTCERT_FILE}

Then start the ./startFabric.sh. It will work!
