This MettleCI capability takes a specified set of input ISX files and modifies them based on instructions provided in a supplied YAML file. The first public interface to the Transmuter function will be made available from the MettleCI command line.
Command
From command-shell MettleCI Command Line, run the asset-transformer transform with command, supplying values for these parameters:
isx: path to an ISX archive or directory containing archives
user: DataStage user to credit changes to
transforms: path to a YAML file describing transforms to perform
YAML file
This file should contain a list at the top level.
Each item in the list should have a property transform, containing the name of
a transform, and other properties required by that transform.
E.g:
| Code Block |
|---|
- transform: AppendToAttribute
xpath: //contains_JobObject[@stageType]/@name
appendString: _I_AM_STAGE
- transform: PrependToAttribute
xpath: //contains_JobObject[@stageType]/@name
prependString: MY_NAME_IS_ |

Description
...
Change prefetch memory
...
recipes/change_prefetchmemory.yaml
...
Change the prefetch memory setting for an ORAOCI9 stage to 102,400,000
...
Add unit test parameter
...
recipes/add_unittest_parameter.yaml
...
Add the $DM_ENABLE_UNIT_TESTING parameter to all jobs in the target folder structure
...
Remove unit test parameter
...
recipes/remove_unittest_parameter.yaml
...
Remove the $DM_ENABLE_UNIT_TESTING parameter from jobs in the target folder structure that have it
...
Change library path and file type
...
recipes/changeStaticLibToDynamicLibFilename.yaml
...
Search the modulePath attribute (of parallel routine definitions, typically) for a given pattern, and replace it with a different directory path, keeping the base name of the file but changing the extension from .o to .so. This changes a statically linked routine to dynamic, helping ensure coherence of routine definitions and routine implementations. Shows how to use the SearchAndReplace transform.
