Appendix C. db2cpic.dll - Extended SNA Security Codes on Windows NT and Windows 95

Extended SNA Security Codes were not implemented by some SNA subsystem providers. This may affect customers using one or more of the following:

vDB2 Universal Database (UDB) for Windows NT Version 5 (all editions).

vDB2 Connect Enterprise Edition for Windows NT Version 5

vDB2 Connect Personal Edition Version 5 (when running on Windows 95 or Windows NT).

A new DLL, called db2cpic2.dll has been provided in order to support Extended SNA Security Codes in these environments. The new DLL was originally packaged with FixPak 1 for DB2 Universal Database Version 5. It is identical to the original DLL db2cpic.dll, except that it includes a call to extract secondary information (cmesi()).

If DB2 fails to load db2cpic2.dll, you can do the following in the directory where it has been installed:

copy db2cpic2.dll db2cpic2.bak copy db2cpic.dll db2cpic2.dll

This will make db2cpic2.dll the same as db2cpic.dll.

Note: If you wish to use Extended Security Support with DB2 UDB Version

5.0on Windows 95, we recommend using IBM Personal Communications (PComm) for Windows 95 Version 4.2 (not Version 4.1). Copy db2cpic.dll to db2cpic.bak and copy db2cpic2.dll to db2cpic.dll. This will make db2cpic.dll the same as db2cpic2.dll.
