IV. Problems Fixed in this Release

A comprehensive list of the problems fixed in this release can be found in
the defects document .
  ------------------------------------------------------------------------
V. Known Problems

A  list of the problems known in this release can be found in the defects
document .  Some issues with workarounds or additional information are
described below:


     CSDK provides a library named 'libgen.a'. On many platforms, however,
     there is a system library with the same name. For reasons of backward
     compatibility, the library is still distributed with the product, but
     users are encouraged to use libifgen.a' to avoid conflicts with the
     system library. Libifgen.a is a link to 'libgen.a'.

     On Sun Solaris 2.7 and 2.8 (64 bit only), when inside an XA
     transaction, if there is an explicit SQL prepare, execute and free in
     a loop in the global transaction, the application may experience a
     catastrophic failure.  (Bug 156193).   As a work around, do not
     explicitly issue a SQL free command; let the system perform this
     operation.
