complete. Lower values will take longer, but
consume fewer processing and I/O resources.
If the POWER clause of a rebalance operation is
not specified, then the default power will be the value of
osm_power_limit.
The plsql_optimize_level
parameter
The plsql_optimize_level parameter specifies the optimization level that will be used to
compile PL/SQL library units. The higher the setting of this
parameter, the more effort the compiler makes to optimize PL/SQL
library units.
Generally, setting this parameter to 2 pays off
in better execution performance. If, however, the compiler runs
slowly on a particular source module or if optimization does not
make sense for some reason (for example, during rapid turnaround
development), then setting this parameter to 1 will result in almost
as good a compilation with less use of compile-time resources.
The value of this parameter is stored
persistently with the library unit.
The plsql_warnings
parameter
The plsql_warnings parameter enables or disables the reporting of warning messages by
the PL/SQL compiler, and specifies which warning messages to show as
errors.
The above is from the bestselling book
