APACHE::ASP Error
Hi,
I'm getting the following error when I run my Perl application
---------------------------------------------

---------------------------------------------
What I understood from this error is that the DB_File module is not
installed. So I tried installing the DB_File module. But then I get
the following error :(

---------------------------------------------
I couldn't find a proper solution for this problem. I saw some
suggestions of installing BerkeleyDB. But isn't that overkill. Do
we really need to install the DB_File and BerkleyDB modules to work
with Apache::ASP?
I also thought of using MLDBM::Sync::SDBM_File instead of DB_File.
But it's mentioned that
The output caching layer is a file dbm based output cache that runs
on top of the MLDBM::Sync so inherits its performance
characteristics.
With CacheDB set to MLDBM::Sync::SDBM_File, the cache layer is
very fast at caching entries up to 20K in size, but for greater
cached items, you should set CacheDB to another dbm like DB_File
or GDBM_File.
So will it be a good idea to use MLDBM::Sync::SDBM_File? Could you
please let me know how to resolve this Apache::ASP error.
Following is the settings in my httpd.conf file.

There are alternate state storage models, but BDB is certainly a good
choice. I seem to recall that one of the options is a native Perl
module (i.e. no C code, as in BDB) but that would be slower.
Bottom line, you definitely need some database layer to store the ASP
state data.
What's wrong with installing BDB? It's been around since before Linux
became the biggest *ix, so it probably builds out of the box on your
Solaris system.
