- 1. User Exits in Informatica MDM
- 2. What is user exit A user exit is custom Java code that you develop that runs at specific points in the batch or Services Integration Framework (SIF) API processes to extend the functionality of MDM Hub. MDM Hub exits regular MDM Hub processing to run code that users develop MDM Hub supplies input parameter values when it calls a user exit
- 3. Sample code public void processUserExit(UserExitContext userExitContext, String stagingTableName, String LandingTableName, String previousLandingTableName) throws Exception { //Entering the Post Landing User Exit logger.info("USER EXIT - POSTLANDING Process User Exit: " + LandingTableName); //Get the values from userExitContext Object String rowidJob = userExitContext.getBatchJobRowid(); //Print some values to Cleanse/Process Server Logs logger.info("Rowid Job: " + rowidJob); logger.info("LDG Table Name: " + LandingTableName); logger.info("STG Table Name: " + stagingTableName); logger.info("PRL Table Name: " + previousLandingTableName); //Get DB Connection from userExitContect Object Connection conn = userExitContext.getDBConnection(); CallableStatement cs = null; //Call mdm_custom_code.post_landing() Procedure cs = conn.prepareCall("begin MDM_CUSTOM_CODE.POST_LANDING (?,?,?,?,?,?); end;"); cs.setString("in_rowid_job", rowidJob); cs.setString("in_ldg_table_name", LandingTableName); cs.setString("in_stg_table_name", stagingTableName); cs.setString("in_prl_table_name", previousLandingTableName); cs.registerOutParameter("out_err_msg",java.sql.Types.VARCHAR); cs.registerOutParameter("out_err_code", java.sql.Types.INTEGER); cs.execute(); cs.close();
- 4. Types of User Exits Stage process User Exits Post-Landing ….delta not started yet Pre-Stage …delta calc is done Post-Stage….raw,rej,stg Load process User Exits Post-Load…. Match process User Exits Pre-Match Post-Match Merge process User exits Post-Merge Unmerge process User Exits Pre-Unmerge Post-Unmerge
- 5. User Exit Usage Post-landing Transform, refine, replace Ctrl Characters, or any Pre-cleansing Pre-staging Any kind of manipulation with the delta process like restricting delta to 10,000,audit delta in a table Post-Staging Mostly used for Reject processing like archiving or deleting rejects (for known logics) Post-load Any customization after data is loaded into base objects like loading child or change consolidation indicator status from 1 to 4 for other tables Pre-Match Any tasks like children tables manipulation like manipulate child tables Post-Match Manipulation of match queue Post-merge Use a post-merge user exit to match and merge child records affected by the match and merge of a parent record.
