Kinda CentOS related so bear with me. :) We have little legacy perl app on an old RH 7.3 box I'm trying to migrate over to a CentOS 4 system. Some information the app uses is in Berkley DB format [root at korma data]# file *.db applic.db: Berkeley DB (Hash, version 5, native byte-order) cables.db: Berkeley DB (Hash, version 5, native byte-order) connector.db: Berkeley DB (Hash, version 5, native byte-order) equipment.db: Berkeley DB (Hash, version 5, native byte-order) hood.db: Berkeley DB (Hash, version 5, native byte-order) interface.db: Berkeley DB (Hash, version 5, native byte-order) wire.db: Berkeley DB (Hash, version 5, native byte-order) If I run the following Perl test script ... #!/usr/bin/perl # # if ($ARGV[0] eq "") { print "\n * * give me a DBM file name to dump (no DBM extension) * *\n"; exit; } dbmopen (%dumpfile, $ARGV[0], 0400) || die "Can't open DB file!" ; foreach $line (sort keys %dumpfile) { print <<END1; $line - $dumpfile{$line} END1 } dbmclose (%dumpfile); Running that against any of the BDB files on the old RH 7.3 system dumps the file's data successfully. Copy everything over to the CentOS system [root at willspc data]# file *.db applic.db: Berkeley DB (Hash, version 5, native byte-order) cables.db: Berkeley DB (Hash, version 5, native byte-order) connector.db: Berkeley DB (Hash, version 5, native byte-order) equipment.db: Berkeley DB (Hash, version 5, native byte-order) hood.db: Berkeley DB (Hash, version 5, native byte-order) interface.db: Berkeley DB (Hash, version 5, native byte-order) wire.db: Berkeley DB (Hash, version 5, native byte-order) Run the script again, e.g... [root at willspc data]# ./dump.pl cables [root at willspc data]# file cables* cables: Berkeley DB (Hash, version 7, native byte-order) cables.db: Berkeley DB (Hash, version 5, native byte-order) And it dumps a new BDB with version 7, no other output. Stracing the process shows it's using DB_File.pm I'm a bit stumped as to what to try next. Will.
