Create a Virtual Node for the MGM
You can create a virtual node using the POST method of the /api/v5_2/virtualnode endpoint. By default, this endpoint configures the node to connect to the standard Corda-managed virtual note databases. Alternatively, if you are using your own virtual node databases, you can specify the connection strings as parameters in the request body. The following sections describe how to use this method:
Create a Virtual Node on Linux or macOS
To create a virtual node for the MGM Membership Group Manager. May also be referred to as the Network Manager. It is a virtual node and Corda identity that acts as a central registrar for group membership. on Linux or macOS, run the following commands in Bash to send the request using Curl, changing the X.500 A series of international standards defining a global directory service protocol for computer networks. It provides a structured framework for storing, accessing, and managing information about network resources and users in a hierarchical and distributed manner. name and using the checksum retrieved when you uploaded the MGM CPI:
export CPI_CHECKSUM=<CPI-checksum>
export X500_NAME="C=GB, L=London, O=MGM"
curl -k -u $REST_API_USER:$REST_API_PASSWORD -d '{ "request": {"cpiFileChecksum": "'$CPI_CHECKSUM'", "x500Name": "'$X500_NAME'"}}' $REST_API_URL/virtualnode
Alternatively, if you are using your own virtual node databases, specify the connection strings in the request body:
export CPI_CHECKSUM=<CPI-checksum>
export X500_NAME="C=GB, L=London, O=MGM"
curl -k -u $REST_API_USER:$REST_API_PASSWORD -d '{ "request": {"cpiFileChecksum": "'$CPI_CHECKSUM'", "x500Name": "'$X500_NAME', "cryptoDdlConnection":"{\"database\":{\"jdbc\":{\"url\":\"jdbc:postgresql://localhost:5432/yourdatabase\"},\"user\":\"cryptoddlconnection_fd545924ff37\",\"pass\":\"WXZS48pRyFQu0GNJNseRMeIL8ZczwfPAHnDJRZdQ11M6fJxjjdhbcKEYSwSiHHqT\"}}","cryptoDmlConnection":"{\"database\":{\"jdbc\":{\"url\":\"jdbc:postgresql://localhost:5432/yourdatabase\"},\"user\":\"cryptodmlconnection_fd545924ff37\",\"pass\":\"d6LIdsVpTwoHaetemyeGWXb0TjRHXOCR6yrxeCCWzWTGiqiDxR5zPuYMBaFdbj6A\"}}","uniquenessDdlConnection":"{\"database\":{\"jdbc\":{\"url\":\"jdbc:postgresql://localhost:5432/yourdatabase\"},\"user\":\"uniquenessddlconnection_fd545924ff37\",\"pass\":\"nVzjzsjfmQpSubHi7K7Rt2Cjlt40wb85zPQQI1KxprmCUswqUJhHH0ovdTy6wYWi\"}}","uniquenessDmlConnection":"{\"database\":{\"jdbc\":{\"url\":\"jdbc:postgresql://localhost:5432/yourdatabase\"},\"user\":\"uniquenessdmlconnection_fd545924ff37\",\"pass\":\"HjgqzcVTohZIapZrgsNz6dlW6U4yHUn6LjCsfG5nwHbuso5hsvAuWBB8DievZX7R\"}}","vaultDdlConnection":"{\"database\":{\"jdbc\":{\"url\":\"jdbc:postgresql://localhost:5432/yourdatabase\"},\"user\":\"vaultddlconnection_fd545924ff37\",\"pass\":\"UwFGEWX9KFfLf9Gai63bUAgcMMh0OzUP9wTRGYEhptkBcfzqScK6tqnz6wSAxN7K\"}}","vaultDmlConnection":"{\"database\":{\"jdbc\":{\"url\":\"jdbc:postgresql://localhost:5432/yourdatabase\"},\"user\":\"vaultdmlconnection_fd545924ff37\",\"pass\":\"PJRFQInjedKZcgf1o0YYq7Dv7vhbsdFL5U7FuCID3S7ZYjPNJ7GITbyTgIofeQwL\"}}"}' $REST_API_URL/virtualnode
You can use the requestId from the response to check that the virtual node was created successfully. Run the following, replacing <request-ID> with the ID received:
curl -k -u $REST_API_USER:$REST_API_PASSWORD -X GET $REST_API_URL/virtualnode/status/<request-ID>
Once the operation is complete, this request returns a JSON object with status set to SUCCEEDED. You may have to call the /virtualnode/status endpoint multiple times until you receive the SUCCEEDED status. Once complete, to save the ID of the virtual node for future use, run the following command, replacing <resource-ID> with the ID returned in the received response:
export MGM_HOLDING_ID = <resource-ID>
Create a Virtual Node on Windows
To create a virtual node for the MGM on Windows, run the following commands in PowerShell, changing the X.500 name. The command uses the checksum of the CPI from the response saved when you uploaded the MGM CPI.
$X500_NAME = "C=GB, L=London, O=Alice"
$VIRTUAL_NODE_RESPONSE = Invoke-RestMethod -SkipCertificateCheck -Headers @{Authorization=("Basic {0}" -f $AUTH_INFO)} -Uri "$REST_API_URL/virtualnode" -Method Post -Body (ConvertTo-Json @{
request = @{
cpiFileChecksum = $CPI_STATUS_RESPONSE.cpiFileChecksum
x500Name = $X500_NAME
}
})
Alternatively, if you are using your own virtual node databases, specify the connection strings in the request body:
$X500_NAME = "C=GB, L=London, O=Alice"
$VIRTUAL_NODE_RESPONSE = Invoke-RestMethod -SkipCertificateCheck -Headers @{Authorization=("Basic {0}" -f $AUTH_INFO)} -Uri "$REST_API_URL/virtualnode" -Method Post -Body (ConvertTo-Json @{
request = @{
cpiFileChecksum = $CPI_STATUS_RESPONSE.cpiFileChecksum
x500Name = $X500_NAME

You can use the requestId from the response to check that the virtual node was created successfully by running the following:
$VIRTUAL_NODE_RESPONSE_STATUS = Invoke-RestMethod -SkipCertificateCheck -Headers @{Authorization=("Basic {0}" -f $AUTH_INFO)} -Uri "$REST_API_URL/virtualnode/status/$($VIRTUAL_NODE_RESPONSE.requestId)" -Method Get
Once the operation is complete, this request returns a JSON object with status set to SUCCEEDED. You may have to call the /virtualnode/status endpoint multiple times until you receive the SUCCEEDED status. Once complete, to save the ID of the virtual node for future use, run the following command:
$HOLDING_ID = $VIRTUAL_NODE_RESPONSE_STATUS.resourceId
