Hi Ed,

We will perform the above steps and will update you with the logs. Meanwhile for the step #7 - com.appiancorp.forms.ajax_1.6.6 this is version we have currently.

It seems it could be a bug with that plug-in. Let's do this:

1. Update these settings to these values

min-pool-size : 5
max-pool-size: 400

2. Add the following tag below </timeout>

<statement>
<track-statements>true</track-statements>
</statement>

3. Restart JBoss and wait for the issue to re-occur

4. Stop JBoss and remove the tag added on step #2 (i.e. <track-statements>)

5. Start JBoss and attach the server log
6. Paste the <validation> section of your data source that is experiencing the behavior
7. Check what version of com.appiancorp.forms.ajax_*.jar you have under <APPIAN_HOME>\\_admin\\plugins

One of the developer confirmed they use the datasource as input to one of the funtion execuutequery...so the answer would be yes to the question #1 in post above .

jdbc/IDAM is our secondary database we are facing issue with. I am giving properties from primary-ds.xml as well.

Please find the IDAM ds porperties:
min-pool-size : 5
max-pool-size: 250
blocking-timeout-millis:5000

appian-ds properties below
min-pool-size : 5
max-pool-size: 100
blocking-timeout-millis:5000

Eduardo Fuentes — Wed, 06 Aug 2014 09:21:50 GMT

The relevant message seems to be

Caused by: javax.resource.ResourceException: IJ000655: No managed connections available within configured blocking timeout (5000 [ms])

so either one of your plug-ins is leaking connections or you are running long queries at a high volume making it run out of connections.

1. Do you use this data source inside a plug-in? Please check with all the developers to verify
2. What's the value of these properties in appian-ds.xml?

min-pool-size
max-pool-size
blocking-timeout-millis

Yes. it is only database we are getting issues with all other database are ok.

RE: Hi Team,

Eduardo Fuentes — Wed, 06 Aug 2014 09:10:33 GMT

Is jdbc/IDAM the one showing this behavior?

RE: Hi Team,

We have a oracle Ds file which stops working time to time. T

Eduardo Fuentes — Wed, 06 Aug 2014 09:05:14 GMT

Or maybe I was looking at a different issue. The one for the Oracle data source shows the following:

Caused by: oracle.net.ns.NetException: Socket read timed out

RE: Hi Team,

Eduardo Fuentes — Wed, 06 Aug 2014 09:04:17 GMT

I thought you said this was happning for an Oracle data source but the stack trace shows the issue is with jdbc/CMS_CN which is MS SQL Server and indicates a login issue:

Cannot open database "XXXX" requested by the login. The login failed.

Hi Ed,
Please find the attached server.log

May I see the whole server.log of when this happened? I'd like to see the entire log if possible.

HI Ed,

We are still getting the below error after adding the mentioned property.

javax.resource.ResourceException: IJ000453: Unable to get managed connection for jdbc

Hi Ed,
We implemented the change and addes the above suggested tag in ds file changing the Word DUAL with one of the table name. But after few hours we faced the same issue and the we redeployed the ds.
Can you please help to trouble shoot taking into consideraion the other possiblity you mentioned that some plugin not working poperly or not closing all the connection properly..Please suggest the next steps towards the solution.

Thanks,
Rahul

Yes

RE: Hi Team,

gauravp — Mon, 04 Aug 2014 20:42:56 GMT

Just checking below property will work with oracle DS.?

(replace the word DUAL with the name of any table in that DB)

<validation>
<check-valid-connection-sql>SELECT 1 FROM DUAL</check-valid-connection-sql>
</validation>

RE: Hi Team,

Eduardo Fuentes — Thu, 31 Jul 2014 07:20:32 GMT

Did you add the suggested tag and restarted JBoss? If even with the tag you're seeing the issue they probably there's a plug-in not closing the connections to that secondary DS but I'd rather start by adding the suggested tag.

Hello Ed,

THe problem is that we have an oracle secondary datasource and the problem is solely with this only. Rest all the datasources are working perfectly fine. Our developers query this oracle database via Appian but after sometime it gives error saying" javax.resource.ResourceException: IJ000453: Unable to get managed connection for jdbc" It seems we dont have any available connection to connect databse. I have also increased the pool size to 250 but problem still occurs.

RE: Hi Team,

Eduardo Fuentes — Wed, 30 Jul 2014 05:08:32 GMT

You add that line to all the data sources to make sure the reconnection is attempted.

@ Ed - Also the I want to specify the database we are facing issue with is a secondary database. Do we need to add the line(mentioned in your comment above) to the DS file of this DB or to the primary primary ds?

Thanks,
Rahul

If the database becomes unavailable for a certain period of time and your appian-ds.xml is not configured to automatically reconnect then you have to restart the application server /redeploy. You can add the following to make sure the app server will try to reconnect (replace the word DUAL with the name of any table in that DB)

<validation>
<check-valid-connection-sql>SELECT 1 FROM DUAL</check-valid-connection-sql>
</validation>

This looks like the Appian application logfile. Alok meant that you should check the logfiles of the Oracle DB server itself.

Hey thanks for turn around : I have checked erro in the log are as : ERROR com.appiancorp.database.ExecuteQuery - java.sql.SQLException: javax.resource.ResourceException: IJ000453: Unable to get managed connection for jdbc/ABC

Thanks,

Hi Gaurav,

You might want to review the logs on the Database server side to check why the connection between the Appian Server and the Database is being dropped. This could be a networking issue.
