Wrong. Stored Procedures continue to run in Stored Procedures Address Spaces. They are stored procedures, and they run in address spaces. Stored procedures do not run in the (one and only one per DB2 subsystem) DDF address space. In the original DB2 support for stored procedures, all stored procedures ran in a single DB2 managed SPAS. This address space was started (optionally) at DB2 initialization, and all stored procedures ran in this address space. However, with later releases of DB2, support was added for executing stored procedures and user defined functions (UDF's) in WLM managed stored procedure address spaces, by defining DB2 specific WLM application environments. However since these are DB2 specific, they are still stored procedure address spaces. What is no longer recommended (and for DB2 9, not supported) is the DB2 managed SPAS, so all stored procedures must run in a WLM application environment. One requirement for WLM stored procedures is the use of RRSAF, in ! place of CAF for DB2 connectivity. RRSAF requires that the RRS logstreams be defined, which in turn require SYSPLEX definitions, even if in MONOPLEX mode. With DB2 9, SQL stored procedures can be defined as "native" which allows them to run in the DB2 DBM1 address space rather than in a WLM address space.

The FM's I've >searched don't give me a clear picture of what is what. First, Stored Procedure Address Spaces have been replaced with Distributed Data Facility (DDF) address spaces. SPAS is still supported, but IBM recommends that you use DDF. Start with the WLM reference which explains Application Environments (a requirement for DDF). It will point you to the proper manuals for configuring DB2 & RRSF (a requirement for the extended Call Attach Facility -- CAF). - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
