a deadlock retry mechanism is essentially down to checking for a deadlock having occurred in a transaction, and resubmitting that transaction if that's the case.

In Sybase::CTlib this means setting up a server message callback with some code that checks for error 1205 (deadlock), and re-sends the transaction that failed if that error code is detected.

For blk_xxx() calls this means that you'll need to "remember" the rows that you sent between blk_done() calls so that you can re-send those rows in case a deadlock is detected.

All of this can be written in perl and in your own code - no real need to subclass Sybase::CTlib (although you could do so) or delve into its C code.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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.
