SDBM creates two files - that is how it works. Both files together make the database. Unless you really, truly, need SDBM for some weird reason, you are much better of using DB_File instead.

The code you showed doesn't put any data into the array you've just tied, so it's hard to say what is going wrong, but I'd like to draw your attention to this part of the SDBM man page: There are a number of limits on the size of the data that you can store in the SDBM file. The most important is that the length of a key, plus the length of its associated value, may not exceed 1008 bytes.
