A spatial engine provides access to a service that can perform spatial operations, one of the available spatial engines is for ArcSDE.

Cohga does not recommend sites update beyond ArcSDE 10.2. ArcSDE 10.3 provides little additional functionality (in fact none that I can find) and ESRI has removed the ability for third party applications (like Weave) to connect to ArcSDE. If you do migrate to ArcSDE 10.3 and wish to continue to use data managed by ArcSDE with Weave you will need to ensure that ArcSDE stores the data using the underlying database native geometry type and have Weave connect to the database directly. |
| Note |
|---|
Supporting Direct Connect is not a trivial matter, it requires a full installation of the ArcSDE client on the Weave server and modifications to the Weave startup (to include the ArcSDE native libraries in Weave). The following links may help. |

pool
Properties
Name | Type | Required | Default | Description |
minConnections | number | no | 2 | The number of connection to create at startup. |
maxConnections | number | no | 6 | The maximum number of objects that can be borrowed from the pool at one. |
timeOut | number | no | 500 | The maximum amount of time to wait, in milliseconds, for an object when the pool is exhausted and whenExhaustedAction is 'block' (otherwise ignored). |
minIdle | number | no | 0 | The minimum number of idle connections in the pool. |
maxIdle | number | no | -1 | The maximum number of idle connections in the pool. |
testOnBorrow | boolean | no | true | Should the connection be checked for validity when being borrowed from the pool. |
testOnReturn | boolean | no | false | Should the connection be checked for validity when being returned to the pool. |
testWhileIdle | boolean | no | false | Should the connection be checked for validity when just sitting in the pool. |
timeBetweenEvictionRunsMillis | number | no | -1 | Sets the number of milliseconds to sleep between runs of the idle connection evictor. This needs to be set if 'testWhileIdle' has been set to true. |
whenExhaustedAction | 'fail', 'grow' or 'block' | no | block | Sets the action to take when the pool is exhausted (the maximum number of "active" objects has been reached). |
minEvictableIdleTimeMillis | number | no | 300000 | The minimum number of milliseconds an connection can sit idle in the pool before it is eligible for eviction. |
softMinEvictableIdleTimeMillis | number | no | -1 | The minimum number of milliseconds an connection can sit idle in the pool before it is eligible for eviction with the extra condition that at least "minIdle" amount of connections remain in the pool. |
lifo | boolean | no | true | If true then the last connection returned to the pool will be the next one handed out, if false then the oldest connection returned to the pool will be the next one handed out. |
