Starting an Engine
3.Select a startup option.
A number of options are available for creating new engine database tables when starting an engine (see “Managing an Engine Database” on page 124):
Startup Option | Description |
|
|
warm | No new database tables are created during the primary engine |
| unit startup process. All information stored in the existing |
| database will be recovered. This option cannot be used the first |
| time an engine is started. |
| Note: If you need to maintain data between iIS releases, or dump |
| and restore data for other reasons, you can use the |
| Dump/Restore utility. For details, see “Dumping and Restoring |
| Data” on page 126. |
cold | All new database tables (current state, registration, and history |
| log) are created during the primary engine unit startup process. |
| The cold option should always be used the first time an engine is |
| started. If used in subsequent engine starts, however, the cold |
| option will cause deletion of the existing engine database before |
| creation of a new |
| and history log data will be lost. |
newLog | New history log database tables are created during the primary |
| engine unit startup process. All history log information stored in |
| an existing database will be lost. |
newState | New current state database tables are created during the primary |
| engine unit startup process. All current state information stored |
| in an existing database will be lost. |
newState | New current state and history log database tables are created |
newLog | during the primary engine unit startup process. All current state |
| and history log information stored in an existing database will be |
| lost. |
newState | New current state and registration database tables are created |
newRegistration | during the primary engine unit startup process. All current state |
| and registration information stored in an existing database will |
| be lost. |

CAUTION Be careful when specifying startup options. All options other than “warm” can result in loss of data. You are asked to confirm a cold start.
