WSO2 Api 管理器 3.2.0 PostgreSQL 问题

Question

我正在尝试使用 WSO2 API Manager 3.2.0

我通过以下链接在 postgre 上配置它https://apim.docs.wso2.com/en/latest/install-and-setup/setup/setting-up-databases/changeing-default-databases/sharing-to-postgresql /#setting-up-postgresql

这 id 我的deployment.toml配置：

[database.apim_db]
type = "postgre"
url = "jdbc:postgresql://xxx.yyy.zz.ww:5432/api_mgr_apim_db"
#hostname = "xxx.yyy.zz.ww"
#port = "5432"
#name = "api_mgr_apim_db"
username = "wso2apimgr"
password = "wso2apimgr"
driver = "org.postgresql.Driver"
pool_options.maxActive = "5"
pool_options.maxWait = "60000"
pool_options.minIdle = "1"
pool_options.maxIdle = "2"
pool_options.testOnBorrow = false
pool_options.validationQuery="SELECT 1; COMMIT"
pool_options.validationInterval="30000"
pool_options.defaultAutoCommit=false

[database.shared_db]
type = "postgre"
url = "jdbc:postgresql://xxx.yyy.zz.ww:5432/api_mgr_shared_db"
#hostname = "xxx.yyy.zz.ww"
#port = "5432"
#name = "api_mgr_shared_db"
username = "wso2apimgr"
password = "wso2apimgr"
driver = "org.postgresql.Driver"
pool_options.maxActive = "5"
pool_options.maxWait = "60000"
pool_options.minIdle = "1"
pool_options.maxIdle = "2"
pool_options.testOnBorrow = false
pool_options.validationQuery="SELECT 1; COMMIT"
pool_options.validationInterval="30000"
pool_options.defaultAutoCommit=false

[database.local]
type = "postgre"
url = "jdbc:postgresql://xxx.yyy.zz.ww:5432/api_mgr_shared_db"
#hostname = "xxx.yyy.zz.ww"
#port = "5432"
#name = "api_mgr_shared_db"
username = "wso2apimgr"
password = "wso2apimgr"
driver = "org.postgresql.Driver"
pool_options.maxActive = "5"
pool_options.maxWait = "60000"
pool_options.minIdle = "1"
pool_options.maxIdle = "2"
pool_options.testOnBorrow = false
pool_options.validationQuery="SELECT 1; COMMIT"
pool_options.validationInterval="30000"
pool_options.defaultAutoCommit=false

我将 postgreSQL 驱动程序放在 component/lib 目录中，并在我的数据库中执行了 postgre.sql 脚本

当我启动服务器时，我收到此错误：

我在 postgreSQL 10 和 postgreSQL 13 上对此进行了测试，但是在这两种情况下，只要我启动服务器，我就会收到错误并且服务器无法启动。

有人可以告诉我如何解决这个问题吗？

更新

正如建议的那样，我通过对共享和用户使用分离的数据库来更改我的deployment.toml 。 现在我的deployment.toml是：

[database.apim_db]
type = "postgre"
url = "jdbc:postgresql://xxx.yyy.zz.ww:5432/api_mgr_apim_db"
#hostname = "xxx.yyy.zz.ww"
#port = "5432"
#name = "api_mgr_apim_db"
username = "credentials"
password = "credentials"
driver = "org.postgresql.Driver"
validationQuery="SELECT 1"
pool_options.maxActive = "20"
pool_options.maxWait = "60000"
pool_options.minIdle = "1"
pool_options.maxIdle = "10"
#pool_options.testOnBorrow = false
#pool_options.validationQuery="SELECT 1; COMMIT"
pool_options.validationInterval="30000"
#pool_options.defaultAutoCommit=false

[database.shared_db]
type = "postgre"
url = "jdbc:postgresql://xxx.yyy.zz.ww:5432/api_mgr_shared_db"
#hostname = "xxx.yyy.zz.ww"
#port = "5432"
#name = "api_mgr_shared_db"
username = "credentials"
password = "credentials"
driver = "org.postgresql.Driver"
validationQuery="SELECT 1"
pool_options.maxActive = "20"
pool_options.maxWait = "60000"
pool_options.minIdle = "1"
pool_options.maxIdle = "10"
#pool_options.testOnBorrow = false
#pool_options.validationQuery="SELECT 1; COMMIT"
pool_options.validationInterval="30000"
#pool_options.defaultAutoCommit=false

[database.local]
type = "postgre"
url = "jdbc:postgresql://xxx.yyy.zz.ww:5432/api_mgr_carbon_db"
#hostname = "xxx.yyy.zz.ww"
#port = "5432"
#name = "api_mgr_shared_db"
username = "credentials"
password = "credentials"
driver = "org.postgresql.Driver"
validationQuery="SELECT 1"
pool_options.maxActive = "20"
pool_options.maxWait = "60000"
pool_options.minIdle = "1"
pool_options.maxIdle = "10"
#pool_options.testOnBorrow = false
#pool_options.validationQuery="SELECT 1; COMMIT"
pool_options.validationInterval="30000"
#pool_options.defaultAutoCommit=false

但现在我得到这个错误：

任何人，好心，为什么我会收到这个错误？

Answer 1

为避免混淆，为SHARED_DB + WSO2CARBON_DB和APIM_DB创建 2 个单独的数据库。

SHARED_DB存储 API Manager 相关数据， SHARED_DB存储注册表和用户管理数据。 默认情况下， WSO2CARBON_DB将是一个嵌入式 H2 数据库，无需将其更改为另一个数据库

例如： SHARED_DB --> shared_db APIM_DB --> apim_db CARBON_DB --> carbon_db

要为 shared_db 创建必要的表，请执行APIM_HOME//dbscripts/postgresql.sql的脚本。

要为 carbon_db 创建必要的表，请执行APIM_HOME//dbscripts/postgresql.sql的脚本。

请注意， APIM_HOME//dbscripts/postgresql.sql包含注册表和用户管理表。 所以我们使用相同的脚本。

要为 apim_db 创建必要的表，请执行APIM_HOME//dbscripts/apimgt/postgresql.sql的脚本。

在 APIM 中配置这些 DB 时，请确保您在配置元素中指定了正确的 DB 名称。

[database.apim_db]
type = "postgre"
url = "jdbc:postgresql://xxx.yyy.zz.ww:5432/apim_db"

[database.shared_db]
type = "postgre"
url = "jdbc:postgresql://xxx.yyy.zz.ww:5432/shared_db"

[database.local]
type = "postgre"
url = "jdbc:postgresql://xxx.yyy.zz.ww:5432/shared_db"

Answer 2

似乎同一个数据库指向SHARED_DB和CARBON_DB 。 您可以将嵌入式 H2 数据库用于CARBON_DB(database.local) ，因为无需更改它。 可以尝试更改database.local以使用 H2 DB 或为 CARBON_DB 创建新数据库并启动包。

请参阅 [1] 中的Changing WSO2CARBON_DB to MySQL部分

[1] https://apim.docs.wso2.com/en/latest/install-and-setup/setup/setting-up-databases/changeing-default-databases/changeing-to-mysql/

Answer 3

关于新的问题，

ERROR {org.wso2.carbon.registry.core.dataaccess.TransactionManager} - Failed to start new registry transaction. org.apache.tomcat.jdbc.pool.PoolExhaustedException: [pool-111-thread-1] Timeout: Pool empty. Unable to fetch a connection in 60 seconds, none available[size:20; busy:20; idle:0; lastwait:60000].

看起来连接池已用尽。 您可以增加 maxActive 连接值并重新检查吗？

#set this to a higher value ex: 50 which is the default value APIM
pool_options.maxActive = "50"
