using `ibmint package`, I can provide an overrides file using the `--overrides-file` command. The same file format can be used with `ibmint apply overrides`.
In this overrides file, I can specify the messageflow, node and property to override.
If I am using subflows within the messageflow and the subflow is in a static library that is provided in the bar file, I can override a property on a node in that subflow using the format "flow/library/subflow#node.property=value".
The IBM Docs ( https://www.ibm.com/docs/en/app-connect/12.0?topic=commands-ibmint-apply-overrides-command ) say:
| Quote: |
When you apply overrides to a work directory, the following syntaxes are allowed, which direct updates to a specific deployment descriptor:
AppName/FlowName#NodeName.PropertyName=NewPropertyValue where:
AppName is name of the application that contains the message flow.
AppName/FlowName#NodeName.PropertyName=NewPropertyValue=NewPropertyValue where:
SchemaName is name of the schema in which the message flow resides within the application.
AppName/LibName/SchemaName.FlowName#NodeName.PropertyName=NewPropertyValue where:
LibName is name of the static or shared library that contains the message flow within the application.
/AppName/FlowName#NodeName.PropertyName=NewPropertyValue where:
The "/" prefixing the application means that this override is required, and the command fails if the property is not found within the application. The "/" prefix also applies when library and schema names are specified.
ShlibName/SchemaName.SubflowName#NodeName.PropertyName=NewPropertyValue where:
ShlibName is name of shared library in which the subflow resides. Promoted properties still take their values from the parent flow or subflow. |
aside from the fact that the docs have a typo ("SchemaName" isn't mentioned in the second example), I have the following queries - all assuming I can't promote any properties to make this easier (because I am using code I can't change except via overrides):
1. The IBM doc examples all use AppName/FlowName, but in all my testing using so far AppName is unnecessary - you can just do `FlowName#Node.property=value`. Is this always true?
2. If I have an application containing two messageflows and a library, each messageflow containing the same subflow from the library; can you override on a per-messageflow basis, or do your overrides apply to the library as a whole? Can you just apply them to the library as a whole? Is there different syntax to cover these different cases?
3. If the subflow from the library contains a second subflow, from a different library (both in the bar file); what then? What's the override format in that case? Is it `flow/library/subflow/otherlibrary/othersubflow#node.property=value`?
Thanks for any help in more generally understanding the options for overrides. |
