Any text following the = is taken as text to follow a ‘CHGQRYA DEGREE’ statement.
For example, specifying DB2DEGREE=SYSTEM would execute the statement “CHGQRYA DEGREE(*SYSTEM)”.
To maintain compatibility with previous releases, if the parameter begins with a digit, it is appended to a “CHGQRYA DEGREE(*NBRTASKS)” statement. A “CHGQRYA DEGREE(*NBRTASKS 1)” statement can be generated with either a DB2DEGREE=1 or DB2DEGREE=“*NBRTASKS 1” statement.
