I'm trying to use perl to help simulate a large number of users accessing an oracle database. The problem I'm running into is during the forking process. I want each db connection to handle a number of SQL commands simultaneously with the others.

I have a package I created which contains a function I wrote for fork, which for forking one instance works fine. I call that method from my script with a for loop wrapped around it to create the number of connections I want to use on the database.

If I use dbi->connect inside the child of the fork, it appears that all the children end up sharing the same DBH. If I create the dbh before the fork and pass it to the child I get strange errors like:

DBD::Oracle::db DESTROY failed: ORA-03113: end-of-file on communication channel (DBD ERROR: OCISessionEnd)

Is there anyone out there who has tried this scenario before and solved it, or who might have some tips on how best to approach this task?

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
