How are you opening these cursors? Are they explicitly opened inside of function/procedure calls or are you opening and closing them in SQL passed to DBI?

If the former, make sure the functions and procedures you call properly close their own cursors. If the latter, make sure you close your own cursors.

I'm currently running many large PL/SQL programs (with many cursors) on AIX running Oracle 9i and have not encountered any max cursor problems. What platform and version of Oracle are you running?

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
• Want more info? How to link or How to display code and escape characters are good places to start.
