Connection Pooling issue #26

lakshmisri · 2015-08-24T19:31:07Z

Hi,

I have used Yank manager for my database connection but beyond a point of time, I am getting "Too many connections". Do I need to handle separately for connection pooling.

Thanks for reporting the issue. I've never seen that before. Can you paste the entire message here?

lakshmisri · 2015-08-24T20:57:42Z

I am using Sundial and Yank for scheduling jobs. I have about 2 batch jobs
and they are scheduled to be executed every 5 min. THe connection
properties that I have used are

jdbcUrl=jdbc:mysql://localhost/localDB
username=root
password=
maximumPoolSize=20

I have just two batch jobs. Assuming one connection per job, it should go
back to the pool. That is my assumption and I have not handled anything
explicitly to return the connection object to the pool.

Hi.. I think you need to upgrade your Hikari jar to higher version. Looks that they have fixed this issue in 2.3.7 onwards. I am using Yank with jdk 7. So they have a stable release yesterday which is 2.4.1

timmolter · 2015-08-25T09:42:35Z

@lakshmisri Thanks for the suggestion. I updated the Hikari jar. Can you please try out the latest Yank snapshot jar?

BTW, I will probably update Yank to Java 7 soon and at that time bump up to the Hikari 2.4.x jar.

lakshmisri · 2015-08-25T10:44:57Z

Yeah that will be fine. I am using Java 7 but still your Yank is working
good :)

Can you confirm that the problem has now been definitely solved?

I have shared a link in the previous comment. Could you take a look at
that? I have also emailed the other team asking for the Java 6 stable
version.

Hi,
the pom.xml does not have the latest jar version, it still shows 2.3.6 but has to be 2.3.9

https://github.com/brettwooldridge/HikariCP

timmolter · 2015-08-25T12:31:32Z

Thanks, I made a mistake. Try now as it should be working.

lakshmisri · 2015-08-26T05:43:04Z

For some reason, its not downloading the dependancy. Does it take some time
for the dependancy to get reflected in maven?

The dependency is there: https://oss.sonatype.org/content/groups/public/com/xeiam/yank/3.0.2-SNAPSHOT/

You're aware that it's a snapshot jar, right?

lakshmisri · 2015-08-26T09:28:53Z

I am using 3.0.1 and not snapshot..

You need to use 3.0.2-SNAPSHOT for the latest changes

Read the README file for more info.

No, it's a snapshot version. I'll release a stable version after I know it's tested and the problem is fixed.

I have put that in my code. Give me a day or two. I will monitor that and

That's hard to believe. Are you sure you're using 3.0.2-SNAPSHOT and not 3.0.1-SNAPSHOT ?

timmolter · 2015-08-26T17:27:12Z

It should be referring to 2.3.9

lakshmisri · 2015-08-26T17:40:46Z

Which one to use. Ur read me said 3.0.2 snapshot

Yank 3.0.2-SNAPSHOT

That is what I have referred to but its not referring to the new one.

You probably have a maven issue. If I look at the deployed snapshot jar on Sonatype, the pom is correct, showing the appropriate Hikari dependency.

lakshmisri · 2015-08-27T07:29:38Z

Ok it is fine now. I will monitor until end of day today and let you know
