What is pct increase setting in oracle?

In Oracle, the PCTIncrease setting (Percentage Increase) is a parameter that defines how much to increase the size of a tablespace when it is auto-extended. It is specified as a percentage of the current size of the tablespace. For example, if PCTIncrease is set to 10%, and the tablespace currently has 100 MB allocated, the next auto-extension will increase its size by 10 MB. This setting helps manage storage efficiently by allowing dynamic growth based on usage.
