Examples

cURL Command

The following example shows how to compensate a Saga transaction by submitting a PUT request on the REST resource using cURL. For more information about cURL, see Use cURL.

Note down the value of the Long-Running-Action and Oracle-Tmm-Tx-Token headers from the response received for a provisional booking. You can pass the values directly or save it in a variable. The Oracle-Tmm-Tx-Token header is displayed in the response body of a provisional booking only if you have created a transaction token and enabled it. See Transaction Token Properties in Transaction Manager for Microservices Developer Guide.

Enter the command on a single line. Line breaks are used in this example for readability. Example values have been truncated with ... to improve readability. When you run this command in your environment, provide the entire value.

curl -X PUT 
     -H "Authorization:Bearer $OTMM_COOKIE"
     -H "Long-Running-Action: [http://otmm-tcs:9000/api/v1/lra-coordinator/57b6...]"
     -H "Oracle-Tmm-Tx-Token: vmrpURFx...qpKmYn2"

  • 15cd86ca-e0b7-4778-8cb6-4b78dfb3b981 is an example value for a Saga transaction ID. Replace this value with the transaction ID of a Saga transaction in your environment.
