Informatica PowerCenter Sources > Create catalog sources in Metadata Command Center > Step 2. Configure capabilities

Step 2. Configure capabilities

When you configure the Informatica PowerCenter catalog source, you define the settings for the metadata extraction capability.

The metadata extraction capability extracts source metadata from external source systems. You can also configure other capabilities that the catalog source includes.

You can save the catalog source configuration at any point after you enter the connection information. After you save the catalog source, you can choose to run the catalog source job. To run the job once, click Run. To run metadata extraction and other capabilities on a recurring schedule, configure schedules on the Schedule tab.

Configure metadata extraction

When you configure the Informatica PowerCenter catalog source, you choose a runtime environment, define filters, and enter configuration parameters for metadata extraction.

1In the Connection and Runtime area, choose a serverless runtime environment or the Secure Agent group where you want to run catalog source jobs.

Note:

Serverless runtime environment options are available if the catalog source works with a serverless runtime environment.

2Choose to retain, delete, or deprecate objects that are deleted from the source system in the catalog with the Metadata Change Option.

- Retain. Retains objects that are deleted from the source system in the catalog. If you update or add a filter, the catalog retains objects extracted from the previous job and extracts additional objects that match the current filter. Objects deleted from the source system are not deleted from the catalog. Enrichments added on deleted objects and relationships are retained.
- Delete. Deletes metadata from the catalog based on objects deleted from the source system and changes you make to the filter. Enrichments added on deleted objects and relationships are also permanently lost. Objects renamed in the source system are removed and recreated in the catalog.
- Deprecate. The lifecycle of objects imported into the catalog moves to Obsolete based on objects deleted from the source system and changes you make to the filter. This does not impact enrichments added on deprecated objects and relationships. Objects renamed in the source system are removed and recreated in the catalog. When you run the catalog source job again for other capabilities such as data classification, relationship discovery, or glossary association, the job doesn't consider obsolete objects. Obsolete objects remain in the catalog until they are purged when you run a Purge Obsolete Objects job on the Explore page.

Note:

You can also change the configured metadata change option when you run a catalog source.

3In the Filters area, define one or more filter conditions to apply for metadata extraction:

aSelect Yes to view filter options.
bFrom the Include/Exclude list, choose to include or exclude metadata based on the filter parameters.
cFrom the Object type list, select All Types.
dEnter a value to specify the object location.

Filters can contain the following wildcards:

▪ Question mark. Represents a single character.
▪ Asterisk. Represents multiple characters.

Note:

For path hierarchies, use source system relevant separators like '.' or '/'. If the object name contains an asterisk, use double quotes. When you enter values for filters, enclose them in double quotes if you include spaces before or after the string value.

The following image shows the filter condition options:

The image shows the Filters area for the Informatica PowerCenter catalog source. You can choose to include or exclude metadata and enter a value to specify the object location.

eTo define an additional filter with an OR condition, click the Add icon.

The following image shows that the filter includes metadata from workflow1 located in folder1 and excludes metadata from workflows with names that start with workflow1 followed by one additional character located in folder1.

The image shows a sample filter with one include condition and one exclude condition.

4In the Configuration Parameters area, specify additional configuration parameters. Click Show Advanced to view all configuration parameters.

The following table describes the properties that you enter for Catalog Source Configuration options:

Parameter	Description
Explicit parameters	Specify additional Informatica parameters with overridden or missing definitions.
Parameter file path replacements	Specify one or more Informatica file mappings to local files. The metadata extraction service uses local copies of files instead of connecting to an Informatica PowerCenter installation. This mapping is used with Informatica parameter files and with indirect source files. The values in the Path field are substituted by the values in the Replacement field in order to resolve workflow parameter file references. You can map the values and then copy the parameter file to the Secure Agent machine. For example, to map the variable file located at $PMRootDir/STG/ParamFiles/Param_File.txt to the local file /home/infa/Param_File.txt, specify the values for the Path and Replacement fields.

Parameter

Description

Explicit parameters

Specify additional Informatica parameters with overridden or missing definitions.

Parameter file path replacements

Specify one or more Informatica file mappings to local files. The metadata extraction service uses local copies of files instead of connecting to an Informatica PowerCenter installation. This mapping is used with Informatica parameter files and with indirect source files. The values in the Path field are substituted by the values in the Replacement field in order to resolve workflow parameter file references.

You can map the values and then copy the parameter file to the Secure Agent machine.

For example, to map the variable file located at $PMRootDir/STG/ParamFiles/Param_File.txt to the local file /home/infa/Param_File.txt, specify the values for the Path and Replacement fields.

If the Informatica PowerCenter repository uses parameter files in sessions and workflows, you can configure Metadata Command Center to read the parameter files when you configure the Informatica PowerCenter catalog source.

A parameter file contains all the parameters and variables and their associated values configured for workflows, worklets, or sessions in the Informatica PowerCenter repository. Informatica PowerCenter parameters can represent flat file sources, flat file lookups, flat file targets, relational connections, expressions at the transformation level, or objects in SQL overrides.

The Informatica PowerCenter catalog source parses the parameter files and substitutes the parameter values to extract metadata for the flat file sources, flat file lookups, flat file targets, relational connections, and objects in SQL overrides. To enable the Informatica PowerCenter catalog source to read parameter values from a parameter file, verify that the file has a .prm or .txt extension.

The following example shows a sample parameters.prm file:

[Map_Param.WF:WF_Src_Tgt_map_param_case.ST:s_src_tgt_tbl_override_default_map_param]
$$Src_OwnName=MM_PERF6
$$Src_TblName=TBL_SAME_COL
$$Tgt_Tbl_Prefix=MM_PERF6
$$Tgt_TblName=INVENTORY_Q4_2005
[Param_lookup.WF:wf_M_LKP_schema_tble
$$LKP_SCHEMA=TEST_DATA
$$LKP_TBL=LKP_TBL_PARAM
[Param_lookup.WF:wf_M_LKP_schema_tbl_sess_param]
$Param_Lkp_Schema=TEST_DATA
$Param_Lkp_Tbl=LKP_TBL_PARAM[
Param_session.WF:wf_session_param.ST:s_session_param]
$Param_Schema_Name=CROSS_RESOURCE_LINKING_DUP
$Param_SrcTbl_Name=SRC_TBL_NAME_OVERRIDE_PARAM
$Param_TgtTbl_Name=TGT_TBL_NAME_OVERRIDE_PARAM
