Celoxis uses JDBC to connect to the database. There could be various reasons for the connection to fail. To help you debug the problem, we have written a simple program that will help you to understand the problem.
Downloading the program
Download the jdbctest.zip file from http://download.celoxis.com/jdbctest/jdbctest.zip and unzip it. This will create a directory containing the following:
- drivers : this contains database drivers from Oracle, Microsoft and Postgresql
- jdbctest.java : this is a simple program that tries to connect to your database using JDBC and prints a success or a failure message
- jdbctest.class : the compiled version of jdbctest.java
This test needs to be run from the server where Celoxis will be installed; NOT on the database server.
Running the test program
- Open a terminal window on Unix/Linux or Command prompt in Windows
- Go to the directory jdbctest
On Microsoft Windows run the program (substituting values according to your configuration) as:
NOTE: Type the words in bold AS IS. Words in italics needs to be substituted.java -cp .;drivers/* jdbctest product=oracle name=celoxis user=scott password=tiger host=localhost
On Unix (or Linux) run the program (substituting values according to your confiuration) as:
java -cp '.:drivers/*' jdbctest product=oracle name=celoxis user=scott password=tiger host=localhost
Note
product | one of the following: oracle (for Oracle), postgresql_90 (for Postgresql 9.0), mssql_2008 (for SQL Server 2008), mssql_2012 (for SQL Server 2012) or mssql_2014 (for SQL Server 2014) |
name | Name of your database |
user/password | Username and Password to be used to connect to the database. NOTE: In case of SQL server, the login and database must be configured to use the SQL Authentication mode (or Mixed mode), not Windows authentication mode only. |
host | The machine name of the server where the database is running |
port | The port of the database server. This is an optional field and when unspecified the default port will be used. |
You will receive a success message if the connection was successful. If the connection fails, the message returned by the driver is printed. If you don't understand the output simply send us the output.
Debugging your database setup
Common errors for Oracle
ERROR MESSAGE | POSSIBLE CAUSES |
---|---|
The Network Adapter could not establish the connection |
|
Invalid username/password; logon denied | Username or password is incorrect |
Connection refused(DESCRIPTION=(TMP=) (VSNNUM=153092352)(ERR=12505) (ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4)))) |
|
Common errors for MSSQL
ERROR MESSAGE | POSSIBLE CAUSES |
---|---|
Error establishing socket. |
|
Login failed for user | Username or password is incorrect. |
Cannot open database requested in login |
|
Not Associated with a trusted SQL Server Connection | This occurs typically when Microsoft Sql Server installation is configured to use only Windows authentication and not SQL Server authentication. To solve the problem: Change the Authentication change the authentication mode to sql server authentication. |
The TCP/IP port is disabled or not accepting connections |
Also, check that the firewall is not blocking the connection. |
Common errors for Postgresql
ERROR MESSAGE | POSSIBLE CAUSES |
---|---|
The connection attempt failed |
|
Connection rejected: FATAL: password authentication failed for user | Username or password is incorrect |
Backend start-up failed: FATAL: database "celoxis" does not exist |
