I have a spring boot application, i tried to connect It to a remote database (postgresql) created in a cpanel server but i got this error: An error occurred while setting up the GSS Encoded connection, to fix It i added gssEncMode=disable, then i got this error : Une erreur s'est produite pendant l'établissement de la connexion SSL. here is my application.properties:
spring.datasource.url=jdbc:postgresql://host:port/db?gssEncMode=disable
spring.datasource.username=admin

Please help me to fix this issue!! Question:how can I get the host and the port of my cpanel server? how can i configure my postgresql database to receive connections from a spring boot application?what are the steps to connect a spring boot application to a postgresql database created in cpanel ?
Add this parameter also to jdbc url then retry :
sslmode=require

I have tried everyting to connect my Chainlink node up to my postgresql database with no luck. I have scoured the interwebs for answers to no avail...
Here is the error message I am receiving:
[ERROR] failed to initialize database, got error failed to connect to `host=/tmp user=root database=`: dial error (dial unix /tmp/.s.PGSQL.5432: connect: no such file or directory)
Here is my .env file:

I have tried every configuration of the connection string. Also I am able to connect to the db via pgAdmin no problem and the dbs are publicaly accessible.
The postgresql database is on AWS.
Please change the syntax of your DATABASE_URL to:
DATABASE_URL=postgresql://"username":"password"#"public-ip-pg-server":5432/"database-name"
just change:
"username" : you need to configure a new user, because the default/admin user postgres will not work for it.
"password" : password of the user
"public-ip-pg-server" : the public ip address of your postgresql-server
"database-name" : the name of your database
PS: delete all " in your syntax (;

I am trying to connect Corda 4.1 (open source) to Azure PostgreSQL.
With the following in the node.conf:
dataSourceProperties = {
dataSourceClassName = "org.postgresql.ds.PGSimpleDataSource"
dataSource.url = "jdbc:postgresql://my-dev-corda-db.postgres.database.azure.com:5432/banks"
dataSource.user = "me#my-dev-corda-db"
dataSource.password = Password
}
It throws the error:
[ERROR] 2019-08-08T23:44:45,301Z [main] internal.NodeStartupLogging.invoke - Could not connect to the database. Please check your JDBC connection URL, or the connectivity to the database.: Could not connect to the

....
....
Suppressed: org.postgresql.util.PSQLException: FATAL: SSL connection is required. Please specify SSL options and retry.
...
So I add ssl=true to the url:
dataSource.url = "jdbc:postgresql://my-dev-corda-db.postgres.database.azure.com:5432/banks?ssl=true"
and it throws the error:

I then tried setting the sslmode=require:
dataSource.url = "jdbc:postgresql://my-dev-corda-db.postgres.database.azure.com:5432/banks?ssl=true&sslmode=require"
which then errors with:

What are the full correct steps to use Azure PostgreSQL with Corda?
When you connect from Internet to Azure PostgreSQL you need to enable your IP in the server's firewall, see: https://learn.microsoft.com/en-us/azure/postgresql/concepts-firewall-rules#connecting-from-the-internet.
You can do it simply from Azure portal - go to Connection Security and Add Client IP (if you don't have a static IP, then you need to repeat it each time).
For JDBC connection settings only ?sslmode=require is needed, so in your node configuration use:
dataSource.url = "jdbc:postgresql://my-dev-corda-db.postgres.database.azure.com:5432/banks?sslmode=require"
I am upgrading my heroku database from a hobby dev to Standard 0 (using the official instructions https://devcenter.heroku.com/articles/upgrading-heroku-postgres-databases#upgrade-with-pg-copy-default).
All went well, until I promoted the new database and restarted the app. I then get the following error:
o.s.boot.SpringApplication : Application startup failed
...
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Invocation of init method failed; nested exception is org.flywaydb.core.api.FlywayException: Unable to obtain Jdbc connection from DataSource
...
Caused by: org.flywaydb.core.api.FlywayException: Unable to obtain Jdbc connection from DataSource
...
Caused by: org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host "54.xxx.xx.xxx", user "u94bf9vxxxxxx", database "d2mqk0b6xxxxxx", SSL off
...
If I swap back to the old database again, everything works again. The only thing that I am changing is the promoted database.
Is there a difference between connecting to hobby and standard databases that I need to be aware of?
The relevant part of my application.yml looks as follows:
spring:
datasource:
driverClassName: org.postgresql.Driver
url: ${JDBC_DATABASE_URL}
username: ${JDBC_DATABASE_USERNAME}
password: ${JDBC_DATABASE_PASSWORD}
flyway:
enabled: true
locations: classpath:db/migrations
Any suggestions on how I can debug this would be very welcome too.
Looks like you aren't connecting with SSL where it is required by Heroku PostgreSQL installs.
See Herokus documentation on SSL for PostgreSQL.
See also Herokus documentation for enabling SSL on JDBC connections.
You will need to add something like &ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory to your JDBC URL.
I am developing for Websphere 8.5 (for z/OS), but i would like to use Liberty for local development on my Windows machine. I can't get the data source to work.
I created the following entry in the Server.xml to define the data source.
<library id="DB2JCC2Lib">
<fileset dir="C:\Program Files\IBM\SQLLIB\java"/><!--includes="db2jcc.jar db2jcc_license_cu.jar db2jcc_license_cisuz.jar"-->
</library>
<dataSource id="xxdb" jndiName="jdbc/xxxx" type="javax.sql.ConnectionPoolDataSource">
<jdbcDriver libraryRef="DB2JCC2Lib" id="db2-driver" javax.sql.ConnectionPoolDataSource="com.ibm.db2.jcc.DB2ConnectionPoolDataSource"/>
<properties.db2.jcc driverType="2" databaseName="xxxx" portNumber="50000" user="xxxx" password="{aes}xxxx"/>
</dataSource>
When my application initializes i get the following error message:
[jcc][4038][12241][3.61.65] T2LUW exception: SQL30081N Kommunikationsfehler. Verwendetes Kommunikationsprotokoll: "TCP/IP". Verwendete Kommunikations-API: "SOCKETS". Position, an der der Fehler erkannt wurde: "127.0.0.1". Übertragungsfunktion, die den Fehler festgestellt hat: "connect". Protokollspezifische(r) Fehlercode(s): "10061", "", "". SQLSTATE=08001
I think this message comes from the db2 Driver, unfortunately i didn't find a way yet to change it to english; but i think it's understandable for english speakers.
I have an ODBC System datasource that connects to DB2 v10 maintenance level 015 for z/OS. My local DB2 Connect Installation is v9.7.300.3885.
In my regular Websphere my working datasource has driver type 2, database Name set to the odbc-name and port number 50000. Server name is not set (empty). Classpath and implementation class is the same that i provided in the server.xml
I have tried everything i could find, any ideas?
Note: I can't make changes on the db2 server and there is no issue connecting to the database with other tools and the regular WebSphere.
Also the server name in the websphere configuration is empty, only database name is set. When i tried to set the servername in the server.xml to localhost or the db2 server i got the same result.
Any help is appreciated!
Edit: updated with correct Version Information
Edit 2: As long as it works i dont care what type (2 or 4) of the jdbc driver is used. I just want to point out again that type 2 is currently working on my machine. I tried it with type 4 and got the following message:
[jcc][t4][2043][11550][3.61.65] Exception java.net.ConnectException: Error opening socket to server xxx/xxx.30.3.34 on port 50,000 with message: Connection refused: connect. ERRORCODE=-4499, SQLSTATE=08001 DSRA0010E: SQL State = 08001, Error Code = -4,499
Sorry, previous post ate my xml. Trying again:
You will need a type 4 datasource to connect to a remote database server, i.e.,
<dataSource id="xxdb" jndiName="jdbc/xxxx" type="javax.sql.XADataSource">
<properties.db2.jcc driverType="4" serverName="the.db2.host.com" portNumber="50000" user="xxxx" password="xxxx" databaseName="LOC1" currentSQLID="SYSA"/>
<jdbcDriver libraryRef="DB2JCC2Lib">
</dataSource>
Type 2 is only for a local z/OS connection to a database resource. Your Windows, being remote from z/OS, requires you to use a type 4 connection. Type 4 requires both the serverName and portNumber to be specified. These are not applicable on a type 2 connection.
