Map caching

Map caching can improve the runtime performance of the WTX Map service. You enable map caching at design time. You can cache any map except for dynamic maps.

Map caching can improve performance because the WTX Map service does not load the compiled map every time the map runs. The WTX Map service loads the compiled map only on the first invocation of the map.

When map caching is enabled, changes that you make to the compiled map are not loaded until the Sterling B2B Integrator server is restarted. When map caching is disabled, any changes that you make to the compiled map are loaded the next time the WTX Map service runs.

Map caching can be enabled or disabled for each instance of the WTX Map service. In the Graphical Process Modeler, set the CacheMap property in the Message to Service tab. Alternatively, configure the BPML with one of the following assignments:

<assign to="CacheMap">YES</assign>
<assign to="CacheMap">NO</assign>

You can enable RUN map caching in the [RUN Maps] section of the tx_install_dir /dtx.ini configuration file. Set RunMapMaxCacheNum to the maximum number of RUN maps to cache.
