I have a shared library which containts implementation(language C) of some utility db2 procedures and functions. Now i want to call these utility functions from db2cmd as,

select epiProcLibVer() from sysibm.sysdummy1

To make this these utiliy functions installed into DB2 db server, i have placed this shared library (libDB2CLIWrapper.so) into <DB2InstallFolder>/sqllib/function

I have restarted the db2 instace to pick and load this library into shared memory of the db server.

Still i am getting the below error @ db2 cmd as below:

db2 => select epiproclibver() from sysibm.sysdummy1
SQL0440N No authorized routine named "EPIPROCLIBVER" of type "FUNCTION"
having compatible arguments was found. SQLSTATE=42884

Now i would like to know whether is it the correct procedure to make a shared library load into db2 db server? how to access the functions in this shared library from sql query?
