APAR Error Description / Circumvention

-------------------------------------------------
Environment Variable to apply to iASP QDBSRV job creation.

CORRECTION FOR APAR 'SE63213' :
-------------------------------
A new environment variable was created called
QIBM_IASP_QDBSRV_JOBS.  This environment variable will function
the same way as the QIBM_WC_DBSRV_JOBS environment variable
does, except that it deals with IASP Database server jobs.

Environment variable name: QIBM_IASP_QDBSRV_JOBS
-If the environment variable is set to *CURRENT, the number of
current processors is used to determine the number of
QDBS###Vxx system jobs to be started.
-If the environment variable is set to *CALC, the average of the
current and maximum configured processors will be used to
determine the number of QDBS###Vxx jobs to be started. For
example, if current = 7 and max = 10, then (7 + 10 + 1) / 2 = 9.
(the 1 is added intentionally)
-If the environment variable is set to *MAX, the maximum
configured processors determines the number of QDBS###Vxx
system jobs to be started.
-The environment variable may also be set to a number between 5
and 99.  This number represents the total number of QDBS###Vxx
jobs to be started. If the number is an even number, one
additional job will be started for the type 1 server job, to
keep an equal number of type 2 and type 3 jobs.
-If the QIBM_IASP_QDBSRV_JOBS environment variable does not
exist or does not contain a valid value, the current number of
processors determines the number of jobs to be started.

CIRCUMVENTION FOR APAR 'SE63213' :
----------------------------------
None.

DESCRIPTION OF PROBLEM FIXED FOR APAR 'SE63577' :
-------------------------------------------------
In a port of code from PLMI -> C++, a small section of the vary
on of an IASP got mixed up.
YASP code calls to IFS, which then tries to resolve to an IASP
library -- this fails since the IASP library isn't created until
a later step.  The failure only occurs on the very first vary on
of an IASP.

CORRECTION FOR APAR 'SE63577' :
-------------------------------
The fix involves moving the IFS call to after the IASP library
has been created.

CIRCUMVENTION FOR APAR 'SE63577' :
----------------------------------
None.
