Microsoft Windows Client Configuration

This table describes the Microsoft Windows client installs and when it needs to be installed.

Microsoft Windows Client machine install	When you need this install
Oracle database 64-bit client	Always install for PUM source.
Enter the tnsnames entry into the tnsnames.ora file	Always enter tnsnames entry for PUM source database. If target database is on Oracle enter the tnsnames entry for the target database.
PeopleTools 8.60 client	Always install for PUM source.
PeopleTools 8.53 through 8.58	Install the PeopleTools client that matches the target environment. Note: If your target database is on a different release than the PUM source, you will have 2 PS homes.
Oracle database 32-bit client	Required if target environment is on PeopleTools 8.53.
Target database client environment Set up database connectivity.	Required if target environment is not on Oracle.

This diagram illustrates the relationship between the Microsoft Windows client running Change Assistant and the PI when your target database is not Oracle.

When the target environment is not on Oracle database, you will always have 2 PS Homes and 2 database clients (one for Oracle and one for the target database platform). The PS Home for the PUM Source database will be on PeopleTools 8.60 and the Target PS Home will be on the same release as the target database.
