Connection pool problem

[Pavol Lackovič]

Hi.

Pls help me with connection pool problem.

I start Jira and after some time raise active connection pool to maximum pool size value.

Then Jira is unusable and i have to restart service.

What is the problem?

My dbconfig:

<jira-database-config>
  <name>defaultDS</name>
  <delegator-name>default</delegator-name>
  <database-type>mssql</database-type>
  <schema-name>dbo</schema-name>
  <jdbc-datasource>
    <url>jdbc:jtds:sqlserver://XXX;instance=XXX</url>
    <driver-class>net.sourceforge.jtds.jdbc.Driver</driver-class>
    <username>XXX</username>
    <password>XXX</password>
    <pool-size>60</pool-size>
<pool-max-idle>15</pool-max-idle>
	<pool-min-size>10</pool-min-size>
	<pool-max-wait>5000</pool-max-wait>
	<pool-remove-abandoned>true</pool-remove-abandoned>
    <pool-remove-abandoned-timeout>30</pool-remove-abandoned-timeout>
	<log-abandoned>true</log-abandoned>
  </jdbc-datasource>
</jira-database-config>

Any update on this

See secure/admin/ViewMemoryInfo.jspa to check if your JIRA instance has enough memory to create connections.

Delete third-party plugins and and look on your JIRA.

Hi, can you check how many connections SQL Server accepts? Does it allow at least 60 connections? It might be an issue of having too many connections and the server doesn't accept it.

Can you let us know which version of SQL Server are you working with?

[Pavol Lackovič]

I am working with SQL Server 2008.

But is normal behavior that number of connection pool is so big?

I had first pool-size parameter set on 20, than 30 and now 60.

And connections is more and more.

Have i set up bigger pool-size parameter?

[Harry Chan]

It's normal if you have a lot of concurrent users doing things. It means that you currently require a lot of concurrent connections, more than the max you have set.

[Pavol Lackovič]

ok.

i try increase max connections.

Thanx

If your install serves < 200 users, you have a plugin that leaks connections. Increasing connections is not the idea.
