Unable to load performance pack. What is the solution for Using Java I/O instead?

The following error is reported when starting:

<BEA-000438> <unable to load Performance Pack. Using Java I/O instead. Please ensure this wlntio.dll is in: ' D:\Weblogic\jdk_64\bin;.; C:\Windows\Sun\Java\bin; C:\Windows\system32; C:\windows;d:\weblogic\patch_wls1033\profiles\default\native;d:\weblogic\patch_oepe1033\profiles\default\ Native;d:\weblogic\patch_ocp353\profiles\default\native;d:\weblogic\wlserv~1.3\server\native\win\x64;d:\ Weblogic\wlserv~1.3\server\bin;d:\weblogic\modules\orgapa~1.1\bin;d:\weblogic\jdk_64\jre\bin;d:\weblogic\jdk_ 64\bin; C:\Windows\system32; C:\Windows; C:\Windows\System32\Wbem; C:\Windows\System32\WindowsPowerShell\v1.0\;D: \program Files\tortoisesvn\bin;d:\weblogic\wlserv~1.3\server\ Native\win\x64\oci920_8 '

Workaround:

Go to the following directory: <<weblogic_home_directory>>\wlserver_10.3\server\native\win\x64, copying Files wlntio.dll and paste it into the C:\Java\bin directory (assuming the JDK was previously installed to C:\Java);

However, in fact, my directory is only the folder 32, there is no x64, this need to go online to download a 64-bit file, and copied to the C:\Java\bin directory, reboot is OK!
