Check if a user exists in Informatica

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.
