HTTP Status 500 IO Error: The Network Adapter could not establish the connection Jira Debian Squeeze Oracle with Service Name

[Flacid Snake]

Hi,

I'm getting this error:

HTTP Status 500 IO Error: The Network Adapter could not establish the connection

I'm trying to use an Oracle11g using Service database following these steps:

https://confluence.atlassian.com/display/JIRAKB/How+to+Connect+JIRA+to+ORACLE+Using+Service+Name

I add the property:

JVM_SUPPORT_RECOMMENDED_ARGS=" -Doracle.net.tns_admin=/opt/atlassian/jira/conf"

The folder /opt/atlassian/jira/conf contains the file tnsnames.ora which looks like:

ORAPRE13 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = myhost.com)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = XEON)
)
)

I edit the dbconfig.xml as follows:

<?xml version="1.0" encoding="UTF-8" ?>

<jira-database-config>

<name>ORAPRE13</name>

<delegator-name>default</delegator-name>

<database-type>oracle10g</database-type>

<schema-name>jira</schema-name>

- <jdbc-datasource>

<url>jdbc:oracle:thin:@//myhost.com:1521/XEON</url>

<driver-class>oracle.jdbc.OracleDriver</driver-class>

<username>user</username>

<password>pass</password>

<pool-min-size>20</pool-min-size>

<pool-max-size>20</pool-max-size>

<pool-max-wait>30000</pool-max-wait>

<min-evictable-idle-time-millis>4000</min-evictable-idle-time-millis>

<time-between-eviction-runs-millis>5000</time-between-eviction-runs-millis>

<pool-max-idle>20</pool-max-idle>

<pool-remove-abandoned>true</pool-remove-abandoned>

<pool-remove-abandoned-timeout>300</pool-remove-abandoned-timeout>

</jdbc-datasource>

</jira-database-config>

What am I doing wrong?

Thanks in advance

I tried to telnet the host and it doesn't connect, so I've asked my network administrator to check if maybe the firewall is blocking the traffic over the 1521 port

Hi,

try to connect to Oracle from the jira server. Try "tnsping ORAPRE13", and if OK, sqlplus.

It's likely a misconfigured listener on the server.

First you should check the network issues(e.g: firewall is blocking port 1521). If network is ok, 

then most probably you have listener configured wrongly, the hostname you specify in connection string must be the same as in the listener.

Thank you Alex Perez. The firewall was blocking the traffic over the 1521 port.

How did you allow it from the firewall in linux centros?

[Flacid Snake]

Please I really need help. The firewall seems to be ok. What am I doing wrong with the configuration above?

Thanks
