WSO2 Api Manager 3.2.0 PostgreSQL issues

Question

I'm trying to use WSO2 API Manager 3.2.0

I configured it on postgre by following this link https://apim.docs.wso2.com/en/latest/install-and-setup/setup/setting-up-databases/changing-default-databases/changing-to-postgresql/#setting-up-postgresql

This id my deployment.toml configuration:

[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

I put the postgreSQL driver in component/lib directory and I executed the postgre.sql script in my databases

When I start the server I get this error:

I tested this on postgreSQL 10 and postgreSQL 13 but in both cases as soon as I start the server I get the error and server doesn't start.

May anybody tell me how to solve the issue?

UPDATE

As suggested I changed my deployment.toml by using separated DB for shared and user. Now my deployment.toml is:

[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

But now i get this error:

May anybody, kindly, why I'm getting this error?

Answer 1

To avoid confusion create 2 separate databases for SHARED_DB + WSO2CARBON_DB and APIM_DB .

SHARED_DB stores API Manager related data and SHARED_DB stores registry and user management data. By default, WSO2CARBON_DB will be an embedded H2 database and it is not necessary to change it to another database

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

To create the necessary tables for shared_db execute the script of APIM_HOME//dbscripts/postgresql.sql .

To create the necessary tables for carbon_db execute the script of APIM_HOME//dbscripts/postgresql.sql .

Note that APIM_HOME//dbscripts/postgresql.sql contains both Registry and User management tables. So we are using the same scripts.

To create the necessary tables for apim_db execute the script of APIM_HOME//dbscripts/apimgt/postgresql.sql .

When configuring those DBs in APIM make sure that you specified the correct DB name in the configuration elements.

[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

Seems the same database is pointed to SHARED_DB and CARBON_DB . You can use the embedded H2 database for CARBON_DB(database.local) as it is not necessary to change it. Can try changing the database.local to use the H2 DB or create new database for CARBON_DB and startup the pack.

Refer the Changing WSO2CARBON_DB to MySQL section in [1]

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

Answer 3

Regarding the new issue which is,

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].

it looks like the connection pool is exhausted. Can you increase the maxActive connections value and recheck?

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