-ua server option

Turns off use of asynchronous I/O.

{ dbsrv10 | dbeng10 } -ua ...

Linux

By default, the database server uses asynchronous I/O on Linux when possible. To use asynchronous I/O, the following conditions must be met:

1. The library libaio.so can be loaded at run time.

2. The kernel has asynchronous I/O support.

If you want to turn off the use of asynchronous I/O, specify the -ua option on the database server command line.
