I want to connect to the Db2 data base server with java application, I use type4 driver, can you please tell me exact location to download DB2 Type4 driver
Thanq in advance
The actually recommended way is to get this from the DB2 server you are working with because it quarantees you get the correct version of them. You can find them from /sqllib/java .

Objective: Set up a connection with PostgreSQL db in PDI. I'm a noob in all this stuff, so each step forward requires long resolution time.
I'm trying to set up the connection to a PostgreSQL database in order to prepare some queries for an ETL process in PDI. But there's no way to succeed with the connection.
I've tried with PostgreSQL connection type and with Generic database connection type and the error is always related with the drivers.
The version of the PostgreSQL db I'm trying to connect is 9.5.25 and I'm working in Ubuntu 20.04 and Java 8 as demands Pentaho Data Integration.
Below the error message after failed connection:
"Connection failed. Verify all connection parameters and confirm that the appropriate driver is installed. Connection to [IP]:[Port] refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections."
I am literally in despair, don't know what I'm doing wrong. Will be very grateful with anyone who can help me.
You need to add the jdbc driver to connect to postgresql DB in the pdi-installation/lib directory, you just put the *.jar file there and restart spoon to have the library available.
That driver can be downloaded from postgresql downloads. The Community Edition of PDI only comes with a small number of jdbc drivers, for each type of database you need to connect to, you should check if the jdbc driver is available in that directory, and if it's up to date or if you need a more recent version of the driver.
This is a link for the official Pentaho documentation, looking for information in Hitachi Vantara documentation is becoming more and more difficult, they don't always clarify what steps apply only for the Enterprise Edition and are not available for the Community Edition: https://help.hitachivantara.com/Documentation/Pentaho/9.2/Setup/JDBC_Drivers_Reference
I'm fairly new to Oracle SQL developer. As I'm trying to make a new connection via TNS, I'm getting this error down below which I've been looking to solve for a while fruitlessly.
Error Message:
Statut : échec -Echec du test : no ocijdbc18 in java.library.path
Assuming MySQL is a typo (You are using port 1521, which is the default port for Oracle database, also its giving you ODBC error, so I assume its an Oracle database. Remember that you can connect SQL developer to a MySQL database, so please clarify if you want to connect to a MySQL database rather than Oracle) your problem is due to lack of Oracle Data Base Connector driver (ODBC). From this link download the latest version of Oracle Instant client and install it on your machine. Then define ORACLE_HOME to the path of Instant client installation (To the actual installation folder, the one that contains folders like bin, network and so on) and restart SQL Developer, then you should be good to go.
P.S. : as #thatjeffsmith has mentioned correctly in the comments, it's not necessary to have Oracle Client and/or ODBC (or similar) drivers in order to connect to an Oracle database. Using basic as the connection type and adding the correct connection info would suffice. This Article in Oracle Magazine has extensively talked about the different connection types.
I had configured the JDBC connection configuration in the pipeline.
and when the application executes i get the following error on the logs.
"java.sql.SQLSyntaxErrorException: Table 'databaseName.aim_table' doesn't exist"
The databaseName is not what I have set.
I have tried many times. it shows the same message that could not find the table in different database, and the question is all the db occurred in the sdc.log are that I had never configured ,and the correct database is never used ,so I want to know how could it find the wrong db and I had checked before start the pipeline and it shows successful:
Do you have anything set in the Schema Name configuration for JDBC
Producer? This should be blank for MySQL, since you're setting the
database/schema name in the connect URL.
Check that your MySQL driver matches the server. In particular, using
the current version 8.0.x JDBC driver with a 5.x.x server seems to
result in this problem. Download the older 5.1.x driver (currently
5.1.46) and it should work.
refer this
This problem is indeed caused by the wrong version of the driver package. I found the correct driver package and successfully wrote the data to the target table. add aonther point, I have set the SCHEMA NAME to blank and defined the database name in the connect URL for mysql.
My English is not good. Please forgive me.
After painful installation of hadoop_fdw into our running pgsql 9.3.4, I am trying to connect it to cloudera cluster 5.2.0 with no luck.
Is there a way of debugging the fdw? After creating the foreign table and selecting from it, I just got an error - ERROR: failed to connect to Hive: No more data to read.
btw.: Some old version of hadoop_fdw was capable of using url (jdbc://server:port/args), but not the recent version, there's just address & port.
Hadoop_fdw didn'd make it. There's probably something wrong/old/obsolete in hive.c. But with even more effort we managed to make jdbc_fdw work with cloudera jdbc drivers. The steps were as follows:
1) install jdbc_fdw extension
2) merge all driver jar files into one
3) CREATE SERVER cloudera2 FOREIGN DATA WRAPPER jdbc_fdw OPTIONS(drivername 'com.cloudera.hive.jdbc4.HS2Driver',url 'jdbc:hive2://fqdn:10000;user=hive',querytimeout '15', jarfile '/opt/cloudera/combined.jar');
mental note: set client_min_messages to debug5; can help you identify where is the problem e.g.:driver not found etc
I have my Oracle server installed in a remote machine and I want a script at my local machine which will check whether Oracle server is up and running or not. I know this can be check by creating a connection through sqlplus or JDBC. But in this case oracle client won't be present and I am saving JDBC approach as my last option. So is there any other simpler way to check this, which can be easily implemented in a shell script???
Thanks
Not really. The only way to be certain that the database is responding to queries is to run a query on it, such as the venerable:
select dummy from dual
