# Global Application Settings

Global runtime settings are stored in the AppSettings. We do not recommend changing the default values. (You should only change these values if our support advises you to do so.)

Treat direct AppSettings changes as controlled maintenance: back up the database, change only documented keys, and restart the service afterward. A restart is especially important for job intervals because ODDC Server schedules them during startup. Individual values may otherwise remain in memory cache for up to 30 minutes.

### 14.1 General, retention, and storage defaults

| Key | Default value | Purpose |
| --- | --- | --- |
| Global.LastWriteOlderThanSeconds | 15 | Minimum file age before hot-folder import |
| Maintenance.DocumentRetentionDays | 30 | Age after which documents are purged |
| Maintenance.BatchRetentionDays | 90 | Age after which batches are purged; values below 90 are forced to 90 |
| Timeout.DocumentLockMin | 30 | Age after which a locked document is returned to import |
| Global.ObjectStorePath | `[Generated UNC path]` | Protected working and output object store |
| LogRetentionDays | 30 | Database setting reserved for log retention |

The log minimum levels are also defined in ar.oddc.server.config.json; in the checked-in configuration they are Warning.
