Hi Simon,
Thank you for your reply. I tired your solution, but I still got the same error message, even when I set PRAGMA busy_timeout = 10000. ------------------ ???? ------------------ ???: "Simon Slavin";<slavins at bigfraud.org>; ????: 2016?5?8?(???) ??11:22 ???: "SQLite mailing list"<sqlite-users at mailinglists.sqlite.org>; ??: Re: [sqlite] database is locked when using SQLite3 and MPI togenerate different databases On 8 May 2016, at 3:14am, just_rookie <925345468 at qq.com> wrote: > But when I ran the program in Linux, I got an error message from > sqlite3_exec() that ?database is locked?. You have not set a timeout, so SQLite is quitting as soon as it is told that another thread/process has the database locked. Set a timeout by executing PRAGMA busy_timeout = 5000 immediately after opening your connection to the database.
