SLOB initialisation parameter file for PIO Testing
This page is found from here – so follow the link if you stumble across it and wonder what it’s all about.
This is the SLOB.CONF I use for PIO testing with the following configuration:
- Oracle 11.2.0.4 RAC or single-instance
- A 2 TB IOPS tablespace
- SLOB configured with 256 users
