what does IBM DB2 z/os JDBC emulateParameterMetaDataForZCalls do?

Question

When i use IBM data Studio to connect to our db2 v8 z/os database the JDBC connection url generated is this.

jdbc:db2://host:port/LOCATION:retrieveMessagesFromServerOnGetMessage=true;emulateParameterMetaDataForZCalls=1;

contains this parameter setting: emulateParameterMetaDataForZCalls=1

What does this setting do? Why do i need it?

I think it's a valid question, so the close vote is not warranted -- the parameter in question is undocumented, so simple googling does not help find an answer. — mustaccio, Jun 02 '14 at 14:46
correct, i just spent half a day trying to find out what this does, and couldnt find any useful info. — Hector, Jun 02 '14 at 15:16

This parameter enables the use of the method PreparedStatement.getParameterMetaData() against a DB2 for z/OS data source.
