在wso2 EI 6.4中，分析文档中的数据库配置未包含在文档中，因为它会使用6.3之前没有的流处理器。我正在尝试使用postgres数据库为ESB配置文件配置wso2 ei 6.4分析数据库。因此，除了carbon db之类的metrics DB, EI Anlytics db以外，配置所需的所有数据库/方案是什么。在
<wso2_home>/wso2/analytics/conf/dashboard/dbscript
<wso2_home>/wso2/analytics/conf/manager/dbscript
<wso2_home>/wso2/analytics/conf/worker/dbscript
只有metrics script for postgres在那儿，我没有得到应该创建哪个数据库/场景。
任何人都可以简要介绍使用POSTGRES DB进行数据库配置所要遵循的步骤。
我尝试使用postgres 9.6，当我配置数据库时，它引发以下异常，但是carbondb是使用postgres 9.6创建的：

答案 0 :(得分：1)
WSO2 EI分析配置文件（流处理器）本身将创建必要的表。您只需要创建所需的数据库，然后在Deployment.yaml中对其进行配置。 This是说明完整群集设置的指南。如果只运行一个工作程序和一个仪表板，则不需要CLUSTER_DB，但其他配置将相同。文档以mysql为例编写。但是步骤对于PostgreSQL是相同的
答案 1 :(得分：0)
似乎仪表板应用程序没有针对PostgreSQL和默认查询的查询。请参阅issue
要覆盖针对Postgres的信息中心应用的查询，请参阅“ Configuring Database Queries”
wso2.dashboard:
queries:
-
type: PostgreSQL
version: default
mappings:
add_dashboard: INSERT INTO DASHBOARD_RESOURCE (URL, OWNER, NAME, DESCRIPTION, PARENT_ID , LANDING_PAGE, CONTENT) VALUES (?, ?, ?, ?, ?, ?, ?)
add_widget_config: INSERT INTO WIDGET_RESOURCE (WIDGET_ID, WIDGET_NAME, WIDGET_CONFIGS) VALUES (?, ?, ?)
get_widget_config: SELECT WIDGET_NAME, WIDGET_CONFIGS FROM WIDGET_RESOURCE WHERE WIDGET_ID = ?
get_widget_name_id_map: SELECT WIDGET_ID, WIDGET_NAME FROM WIDGET_RESOURCE
delete_widget_by_id: DELETE FROM WIDGET_RESOURCE WHERE WIDGET_ID = ?
get_dashboard_by_url: SELECT ID, URL, OWNER, NAME, DESCRIPTION, PARENT_ID, LANDING_PAGE, CONTENT FROM DASHBOARD_RESOURCE WHERE URL = ?
get_dashboard_metadata_list: SELECT ID, URL, OWNER, NAME, DESCRIPTION, PARENT_ID, LANDING_PAGE FROM DASHBOARD_RESOURCE
delete_dashboard_by_url: DELETE FROM DASHBOARD_RESOURCE WHERE URL = ?
update_dashboard_content: UPDATE DASHBOARD_RESOURCE SET NAME = ?, DESCRIPTION = ?, CONTENT = ?, PARENT_ID = ?, LANDING_PAGE = ? WHERE URL = ?
