Parameter documentation
If you set this parameter, it deactivates parts of the effect of the
database hint 'SINGLE_EXECUTION'>. Although affected SQL
statements are prepared in special, temporary SQL packages, existing
statement resources are not necessarily released again immediately.
Setting this parameter can have a significant effect on system
performance.
