The pUsage parameter specifies the database usage. The usage constants and their integer values are listed in the following table.
| Constant | Value | Description |
|---|---|---|
| DB_UPDATE | 0 | Enables applications to update the database. |
| DB_READ_ONLY | 1 | Specifies that your applications have read-only access to the database. |
| DB_NO_AUDIT | 2 | Specifies that the recovery log is not maintained. This usage can result in better performance, but if an abnormal termination occurs and the database is not audited, recovery is not possible and the database must be restored from backup. Use the shared access mode to specify multiple users with no‑audit usage. However, if any one application or shared‑access user opens the database in no‑audit mode, all users must request no‑audit usage or a conflicts exception is raised. |
