Ok, I's used DBI with mysql on Linux, now I need Oracle from an NT machine I installed DBI with Activestate 5.8, and also the oracle client(stopped the installation at the optional parts which were taking too long),then grabbed DBD-Oracle1.17 (the activestate ppm repositories only list 1.18 which fail even on Windows) So I unzipped the DBD-Oracle1.17 and did ppm install DBD-Oracle.ppd which started by a long preamble to which I answered y and then... Fetching oci.dll (336 Kb) 336Kb/336Kb (100%) oci.dll checksum: ok Fetching oraociei10.dll (86Mb) 86Mb/86Mb (100%) Invalid checksum for c:\perl\bin\oraciei10.dll at ./ioic line 76 compilation failed in require at install_script line 1 with some moe unlinking mesages and failing to unlink a directory. Am I doing something wrong here? Do I have a corrupted zip file? SHould I scrap ppm and try to do the installation with nmake? Does anyone have a procedure of how to install DBD-Oracle on a windows machine?
