Re: Performance problem with V6R1

[Luis Rodriguez <luisro58@xxxxxxxxx>]

*Conversion of module, program, and service program objects*

The conversion from software-based process local addressing to
hardware-based process local addressing

requires that all modules, programs, and service programs created on
releases before V6R1 be converted

to be used on V6R1 and later releases.


The conversion will take some time. There are three different options for
when conversions can occur:

* You can convert objects as they are restored onto a V6R1 system. This type
of conversion slows down

the restore operation, but eliminates the need for any later conversions.


* You can use the Start Object Conversion (STROBJCVN) command to explicitly
convert objects at some

point after the restore operation, but before calling the objects for the
first time.


* You can convert an object the first time that it is called, which can
cause some delay until all objects

have been converted. This option does not require any explicit conversion
actions.


For any of the conversion methods, the length of time it will take for a
particular object to be converted

depends on several factors. These factors include the size of the object to
be
