Re: [sqlite] Database is locked when working in 2 processes
This issue has been resolved. I did not call sqlite3_finalize() in the reader process and kept the READ lock How to read after the database was written by another process? Reading function should wait until other process finishes writing and unlocks the file. But in our case unlocking never happens after writing is finished. Only when you restart the reader process in can read again. - To unsubscribe, send email to [EMAIL PROTECTED] -

Many threads or process can read, but just one can write, and when is writen the DB is locked, even for read. How to read after the database was written by another process?

Process 1 is writing to the database periodically in autocommit mode. Process 2 only reads from the same database file. After awhile Process 2 starts getting "Database is locked " error and can not read anymore until you close and open the process 2 again. How is such configuration supposed to work in SQLite when we need 1 writer process and 1 or more reader processes?
