Message: [QUOTE="Dan, post: 4748588"] Has anyone knwoledge to share about tied hashes as database backend in cgi-scripts? I'm running a CGI that will acess a DBM file (DB_File) as a tied hash like this: sub pseudo-code{ tie %hash read(!) something untied %hash } Do I have to use a file lock algorithm wrapped around when I am just goint to READ from the file? Will file corruption over time be a problem? (the script will be running on a heavy load website, multiple processes, maybe sometimes to read all at once) As I udnerstand it I'll have to lock the DB_File only for write/read-write access, but for reading only??
