# oz0 memory settings set

> Change how long plugins' records last and how much one scope holds, and which purposes read each other's records.

For: Operators and developers looking up a command.

Change how long plugins' records last and how much one scope holds, and which purposes read each other's records. Every flag left out keeps its value. --compatible from>to lets jobs for purpose to read records written for purpose from (repeat for more; it replaces the list, and --no-compatible clears it); reading never grants writing. A job without a purpose reads only records written without one.

A later default or longest end, a higher cap and a new pair loosen: with four eyes on they wait for another admin. A change applies to writes from then on; records already written keep their ends (a later version that carries its record's end past a lowered longest end is brought down to it). Closed and ended records count toward the caps until retention removes them.

## Usage

```bash
oz0 memory settings set [flags]
```
