DB2 FOR LUW / DB2FORLUW / A10 - DB2

By default, the file system caching attribute is "unspecified", 
meaning it has an automatic or default behaviour as specified in 
documentation.  see "File System Caching Configurations". 
 
The tools which report the default file system caching attribute 
only report the preference DB2 has per operating system, which 
can be misleading.  Instead of "default" it will report the file 
system caching is Off for AIX,Linux,Solaris, and Windows, and On 
for HP and Linux390.  However, this will not be the correct 
interpretation for certain filesystems as DB2 will request the 
opposite behaviour (as documented).  In addition, it is 
impossible to distinguish between the default/unspecified 
setting and a user-specified setting that is equivalent to the 
default behaviour. 
 
This APAR will change the displaying of the File System Caching 
attribute to include the "default" setting.  It will be 
necessary to consult the documentation to determine the intended 
DB2 behaviour.
