1 Alternate Methods for Informatica Metadata Exchange SDK Informatica Metadata Exchange SDK provides a set of COM-based APIs for exchanging metadata with the PowerCenter repository. You can also use this SDK to write or update source and target definitions in the repository. However, Metadata Exchange SDK has several limitations. For example, SDK is limited to the Windows platform. Also, you can only update source and target definitions. Effective in version 8.5, Informatica Metadata Exchange SDK is no longer supported. If you have applications created using Metadata Exchange SDK, you must modify them to avoid receiving error messages. Use the following alternate methods to obtain the same results as Metadata Exchange SDK: pmrep command line program MX views Java Mapping Framework pmrep Command Line Program pmrep is a command line program that you use to update repository information and perform repository functions. pmrep is installed in the PowerCenter Client and PowerCenter Services bin directories. You can use pmrep to perform repository administration tasks such as listing repository objects, ing objects from an XML file, or exporting objects to an XML file in the PowerCenter repository. For example, complete the following steps to objects into the repository: 1. Connect to the repository. Use pmrep Connect to connect to the repository. 2. List objects in the repository. Use pmrep ListObjects to list repository objects such as sources, targets, folders, labels, and tasks. 3. Import objects into the repository. Use pmrep ObjectImport to objects from an XML file. For more information about using pmrep, see the PowerCenter Command-Line Reference. MX Views PowerCenter Metadata Exchange (MX) provides a set of relational views that allow easy SQL access to the PowerCenter metadata repository. MX views provide information to help you analyze metadata stored in the repository. For example, if a source table changes, and you need to re- the source definition into the repository, you can use the REP_SRC_MAPPING view to see how many mappings include this source. Query this view by MAPPING_NAME and VERSION_NAME. A 1

2 mapping might contain several sources. This view contains the mapping names defined for an individual source table. Table 1-1 lists mapping source metadata in the REP_SRC_MAPPING view: Table 1-1. REP_SRC_MAPPING MX View Column Name Datatype Description SOURCE_NAME VARCHAR2 (240) Name of the source. SOURCE_ID NUMBER Source ID. SRC_BUSNAME VARCHAR2 (240) Business name of source table. SUBJECT_AREA VARCHAR2 (240) Folder name. SUBJECT_ID NUMBER Folder ID. MAPPING_NAME VARCHAR2 (240) Mapping name. MAPPING_ID NUMBER Mapping ID. VERSION_ID INTEGER Folder version ID. VERSION_NAME VARCHAR2 (240) Folder version name. MAPPING_COMMENT VARCHAR2 (2000) Mapping comment. MAPPING_LAST_SAVED VARCHAR2 (30) Time the mapping was last saved. MAPPING_VERSION_NUMBER NUMBER Mapping version number. SOURCE_VERSION_NUMBER NUMBER Source version number. Use the fields in bold to join views. With MX software and support from Informatica, vendors of popular query and reporting tools can quickly create a metadata link between their products and the PowerCenter repository. For more information about using MX views, see the PowerCenter Repository Guide. Java Mapping Framework Java Mapping Framework provides a java-based API that allows you to create and edit repository objects. Example 1 - List Repository Objects Use the following code to list objects in the PowerCenter repository: * ListObjects.java Created on Jan, * Copyright (c) 2008 Informatica Corporation.
