Specifies whether your connection should take advantage of the database server threadsafe client libraries.
By default, ThreadSafe is set to No to specify that your connection does not use the threadsafe client libraries. If you set ThreadSafe to Yes, your connection takes advantage of the threadsafe client libraries.
When to specify ThreadSafe
You must specify a value for ThreadSafe before connecting
to the database.
I10 Informix
IN9 Informix
O90 Oracle9i
O10 Oracle 10g
ORA Oracle 11g
ThreadSafe='value'
ThreadSafe='No'
When to use Oracle and Informix provide support for thread safety in their client libraries. When you are using the Oracle or Informix database interface to build multi-threaded applications in PowerBuilder, set the ThreadSafe parameter to Yes to use threadsafe client libraries. This prevents possible side effects among multiple threads of execution making calls to the database server. Your application might incur a performance penalty when you use the threadsafe client libraries.
By default, the client software (and, thus, PowerBuilder) assumes that you are building an application in a single-threaded environment that does not need the threadsafe client libraries. This default ensures that single-threaded applications do not incur the performance penalty associated with using threadsafe libraries. Therefore, if you are building single-threaded applications, you can leave the ThreadSafe parameter set to No (the default).
This parameter cannot be set dynamically. The value set when the connection is made remains in effect until it is disconnected.
To specify that your connection uses the threadsafe client libraries:
Database profile Select the Thread Safe check box on the Connection page in the Database Profile Setup dialog box.
Application Type the following in code:
SQLCA.DBParm="ThreadSafe='Yes'"
