EZZ9306I

Explanation
 A MODIFY RESOLVER,REFRESH,SETUP=setup_filename command
was issued, and the value specified for the CACHESIZE parameter or
the default value that is used when the CACHESIZE parameter is not
specified in the setup file, is smaller than the current setting.
The CACHESIZE setting can only be increased dynamically.

System action
 The value for the CACHESIZE parameter is left
unchanged, and the MODIFY RESOLVER,REFRESH,SETUP command fails.

Operator response
 Contact the system operator.

System programmer response
 Use the NETSTAT RESCache/-q
SUMMARY command or the MODIFY RESOLVER,DISPLAY command
to determine the value of the CACHESIZE parameter
for the resolver cache.  Specify a value for the CACHESIZE parameter
in the file specified by the setup_filename value
so that the CACHESIZE value is equal to or
larger than the current value. Re-issue the MODIFY RESOLVER,REFRESH,SETUP command.
 Alternatively,
issue a MODIFY RESOLVER,REFRESH,SETUP=setup_filename command,
where the NOCACHE parameter is specified in
the setup file. Then, issue a second MODIFY RESOLVER,REFRESH,SETUP=setup_filename command,
where the CACHE parameter is specified (or
the default value is used) in the setup file, and the CACHESIZE parameter
with the required value is also specified. 
 Alternatively,
issue the STOP RESOLVER command to stop the
resolver, and then  restart the resolver with the smaller value for
the CACHESIZE parameter.
