API Gateway Package Configuration Properties
API Gateway uses Internal Data Store (Elasticsearch) as its data repository. API Gateway starts the Internal Data Store instance, if configured, using the default configuration shipped and located at SAG_root/InternalDataStore/config/elasticsearch.yml
Note:
To run Internal Data Store instances in a cluster, the
elasticsearch.yml file must be updated on each instance. For additional details, see
Elasticsearch documentation.
Location : SAG_root/IntegrationServer/instances/IS_Instance_Name/packages/WmAPIGateway/config/resources/elasticsearch/config.properties
pg.gateway.elasticsearch.autostart
Denotes the flag to manage (start or stop) Internal Data Store as part of API Gateway. Set it to false if the start or stop of Internal Data Store is managed from outside the API Gateway.
Available values: true, false.
Default value is true.
pg.gateway.elasticsearch.start.maxwait
Denotes maximum time in seconds API Gateway waits for Internal Data Store to start and stop if autostart is set to true.
Default value is 300.
pg.gateway.elasticsearch.config.location
Denotes the location of the config file. If you have to use a different config file, mention the location of the config file here.
Default value is SAG_root/InternalDataStore/config/elasticsearch.yml
Note:
If the Internal Data Store hostname is same as localhost, then the system automatically modifies the value of
<prop key=cluster.name> in
SAG_root/IntegrationServer/instances/IS_Instance_Name/packages/WmAPIGateway/config/resources/beans/gateway-datastore.xml to
cluster.name property in the elasticsearch.yml file.
If the Internal Data Store hostname is same as localhost, then the system automatically modifies the port value of <value>localhost:9340</value> in
SAG_root/IntegrationServer/instances/IS_Instance_Name/packages/WmAPIGateway/config/resources/beans/gateway-datastore.xml to
transport.tcp.port property in the elasticsearch.yml file.
Ensure that the cluster.name and transport.tcp.port properties are in synchronization if you encounter any errors.
