    This was great. I will be sure to link to this on an post I writing today on using Oracle BI Apps with an Oracle XE database. Upon my attempt, I bumped into the same issue as you did. Ultimately I bumped into another issue that was and impassible restriction of Oracle XE and had to chuck the idea. But good post by you none the less.

  2. Thanks for the good article. It helped a lot. I wrote an blog entry in german myself and referenced to your one.

    I spent three days trying to resolve this problem, but after that, in a morning after drinking a beer, I found this article and it resolved the problem. Thanks, great work.

    Tried but couldn’t get it to work. Or at least not as I want. Still with the value setted to 150, after 45 concurrent calls it throws the exception. =(

    thank you — muchas gracias !

  26. Matejbor says:

    Thank you for the idea but I cannot agree that this is the solution. It is merely a bypass. There was the same option in Snow Leopard and I didn’t want to use it as I didn’t want my computer waking up with the lid down. But still after sleep I got a connection with my mouse every time. This obviously remains a bug.

  37. dede says:

    i was try this command, but can’t resolving this problem
    after execute this command, i get this message

    SQL> alter system set processes=150 scope=spfile;
    alter system set processes=150 scope=spfile
    *
    ERROR at line 1:
    ORA-32001: write to SPFILE requested but no SPFILE is in use

  38. Ken Ng says:

    Try the following set of commands to fix that.

    create spfile from pfile;
    shutdown immediate;
    startup;
    show parameter spfile;

    Thanks It’s work like a charm . Prior reading this article I started believing that there must be some glitch in my code. Thanks again.

  49. Chandrasekhar says:

    It didn’t work for me. Can you give me reset command for above and let me know any other solution for it

  50. Ken Ng says:

    Chandrasekhar: The command above only increases the number of processes the Oracle DB XE can run concurrently. So its actually good to have that increased even if this didn’t solve your problem.
