Обсуждение: Set application name from jdbc url

Hi,

I want to set the application name of the connections of my application.
Then I can list the rows in `pg_stat_activity` with a non empty
`application_name` column.

I have setup the following JDBC url for connecting to my Postgresql
database:

     jdbc:postgresql://localhost:5435/MyDB?application-name=MyApp

I have tried also this url with no more success.

     jdbc:postgresql://localhost:5435/MyDB?application_name=MyApp

I also tried these two variant of application name parameter :
*applicationName* and *ApplicationName* with no luck.

What is the correct parameter name ?

Here is my JDBC driver version:  **9.1-901.jdbc4**
I try to connect a Postgresql server : 9.2.4 - 64bit - running on Windows 7

Try "ApplicationName" [1]. Also, you can set it on the Connection
object after creation via the JDBC standard setClientInfo(...)
method[2].

[1]: https://github.com/pgjdbc/pgjdbc/blob/master/org/postgresql/core/v3/ConnectionFactoryImpl.java#L639
[2]:
http://docs.oracle.com/javase/7/docs/api/java/sql/Connection.html#setClientInfo%28java.lang.String,%20java.lang.String%29

The solution from [2] works like a charm.

However, the solution from [1] doesn't work :\

I have set up a database connection from the Datasource explorer in Eclipse,
with the following JDBC url:

        jdbc:postgresql://localhost:5435/REC?ApplicationName=ZOZOZOZ

 From pgAdmin III, here are the results of the following query : select
pid, application_name from pg_stat_activity

9212;""
6396;""
4628;"psql"
6796;"pgAdmin III - Navigateur"

The results of the same query running from psql:

  pid  |          application_name
------+-------------------------------------
  9212 |
  6396 |
  4628 | psql
  6796 | pgAdmin III - Navigateur

I have tried to set up a connection manually and I get the same similar
results: ZOZOZOZ seems to be an unknown application name.

Try it with the latest version of the JDBC driver (currently
9.2-1003-jdbc4). Maybe your older driver is causing the issue (above
says you're using v9.1-904).

I'm able to test setting the client name and verify it via
pg_stat_activity using the latest driver connecting to 9.1, 9.2, and
9.3. I tried it via a URL property, setClientInfo(...), and explicitly
setting a java.util.Property value and all three worked fine.

Try it with the latest version of the JDBC driver (currently
9.2-1003-jdbc4). 

maven central

I need this version. I quite don't understand why it is not deployed on
central like jdbc4.

How many days do you need for pushing this version to maven ?

I can set something up for this if need be.  I am not sure what I would need to submit to maven central but I can do that as well if I can get some instruction.

Stephan,

My challenge is mostly finding a machine that I can push from and build jdbc3. Assuming those two are possible I may be able to do this next week.
