Use SQL (or any other HLL) to compare character and graphic data in two different products where their database CCSIDs are different (e.g. CCSID 65535 and CCSID 13488). This can be done without handling the data type conversion within SQL itself. All you need to do is to ensure the SQL program is running with job attributes that point to a system CCSID. When this is done, i5/OS automatically handles the conversion.

09/23/08 How to always see correct field names for a physical file
To quickly see the fields that are available in a physical file without having to run a SQL statement use the DSPFFD command.
- Type from command line DSPFFD
- Press F4
- Type the File name and the Library where it is located
- Press Enter
This simple command is often superior to running a SQL statement because the names of fields in a file are not always correctly shown when using SQL. The DSPFFD command will always return the correct naming convention of the column names.

To use a different version of Java as the default runtime environment for a specific user, create a new STMF file on the IFS within the home directory for the user as follows:
/home/UserPrf/SystemDefault.properties
Note: Replace underscored values with appropriate values.
This file should contain one line (e.g. 1.4, but it can be any version that is installed on the system), i.e.: java.version=1.4
Save and exit the file and that User will now be using this specified version of Java.
