'Another point to remember is that when you use persistent threads
with RELEASE(DEALLOCATE), there is a tradeoff. Doing so will impact
BIND/REBIND and SQL DDL concurrency. When you have a high-volume
transaction that justifies use of persistent threads with
RELEASE(DEALLOCATE), then BIND/REBIND and DDL activity cannot break
in.'

RSM is a part of DB2.  One option of BINDING (connecting the compiled
SQL statement and program object code) is to keep the SQL code in
storage until deallocated to save overhead.  The side effect is other
tasks can't BREAK in to access the database. I assume this APAR
attempts to ease problems with a z13 hardware feature.
