The cure for the direct path write waits is to locate and tune the SQL statement to reduce the number of sorts and eliminate hot disks. When the statement is executing, examine the P1 values.

If they mostly point to the TEMP tablespace, this means the statement is performing disk sort operations, and if there are a lot of them, then the statement must be tuned to reduce the number of sorts. In this case, use the appropriate operating system tools or utilities such as sar —d or iostat —dxn to ensure that there are no hot disks. Parent topic: Oracle Database Specifications for Windows.

If you do not specify a different initialization file with the option PFILE at database startup, then by default Oracle Database uses initialization parameter files located in. If you create a database manually using an SQL script, then you are required to create an initialization parameter file or copy an existing initialization parameter file and modify the contents. If you use Database Configuration Assistant to create a database, then the initialization parameter file is automatically created for you.
