If you are using DB2 WWW Version 1 and want to migrate to Net.Data (DB2 WWW Version 2), read "Getting Up and Running with Net.Data". If, after reading the section, you think you need a Net.Data initialization file (as explained in the section just read, you will need to create an initialization file if URLs that reference Net.Data macros do not fully qualify the location of the Net.Data macro), create one. If you decide to create an initialization file, you need to add a SQL language environment statement in the initialization file (see "SQL (DTW_SQL or SQL) Language Environment" for information on the syntax of the SQL language environment statement).
With DB2 WWW Connection Version 1, you needed an initialization file in every library in which macro files resided. This is no longer true with Net.Data. If you choose to create a Net.Data initialization file and you use the MACRO_PATH configuration statement in your DB2 WWW Version 1 initialization files, you need to combine the path statements into one path statement and insert the combined path statement in the initialization file in the library where the DB2WWW program object resides. Once Net.Data is serving Net.Data macros, you should delete all the DB2 WWW Version 1 initialization files that are not being used.
