DESCRIPTION

Returns messages from the specified stream using the specified cursor as the starting point for consumption. By default, the number of messages returned is undefined, but the service returns as many as possible. To get messages, you must first obtain a cursor using the CreateCursor <https://docs.cloud.oracle.com/en-us/iaas/tools/oci-cli/latest/oci_cli_docs/cmdref/streaming/stream/cursor/create-cursor.html> operation. In the response, retrieve the value of the ‘opc-next-cursor’ header to pass as a parameter to get the next batch of messages in the stream.

The top level –endpoint parameter must be supplied for this operation.

USAGE

oci streaming stream message get [OPTIONS]

REQUIRED PARAMETERS

--cursor [text]

The cursor used to consume the stream.

--stream-id [text]

The OCID of the stream.

OPTIONAL PARAMETERS

--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--limit [integer]

The maximum number of messages to return. You can specify any value up to 10000. By default, the service returns as many messages as possible. Consider your average message size to help avoid exceeding throughput on the stream.

GLOBAL PARAMETERS

Use oci --help for help on global parameters.

--auth-purpose, --auth, --cert-bundle, --cli-auto-prompt, --cli-rc-file, --config-file, --debug, --defaults-file, --endpoint, --generate-full-command-json-input, --generate-param-json-input, --help, --latest-version, --max-retries, --no-retry, --opc-client-request-id, --opc-request-id, --output, --profile, --query, --raw-output, --region, --release-info, --request-id, --version, -?, -d, -h, -i, -v

EXAMPLES

Copy the following CLI commands into a file named example.sh. Run the command by typing “bash example.sh” and replacing the example parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-like shell. You need to set up the OCI configuration <https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/cliinstall.htm#configfile> and appropriate security policies <https://docs.oracle.com/en-us/iaas/Content/Identity/Concepts/policygetstarted.htm> before trying the examples.
