Socket Read Timed Out Error - Migrating JIRA from mySQL to Oracle.

[Leighton Leighton]

I have taken a backup from our current production instance of JIRA, which uses a mySQL database instance. Recently i created a test environment to install a development version of JIRA into which connects to an Oracle database, to validate prior to migrating to a new production instance of JIRA connected to an Oracle Database.

During the 'Restore data from XML' the import is failing. Here is an exert from the log file.

"Running JIRA Data Import...

Importing XML data...

XML successfully parsed.

Removing all entries from the database.

All entries removed.

Note: For posting purposes i have removed usernames and IP addresses etc.

There are heaps of these Socket read timed out errors.

Any ideas on how i approach troubleshooting this issue would be appreciated.

Thanks for your input Martin. I found the issue in the end was related to an issue in resolving the dns names, and a port that had not been opened up. I also did the restore of data from an existing instance using http://localhost/ (ie opening the JIRA client on the server itself). The restore took many hours, but worked successfully. The test connection function in the JIRA Config tool is a good indication. If this is not connecting successfully, don't try restoring data until you have resolved this point. Once we had this test connection resolving correctly the import went without a hitch. :)

Hi Leighton

More info is needed to really get into detail i.e. versions of java, os, oracle, jira, but would go back to basics and doublecheck all the configurations, If it does succesfully make a connection at times, then would jump to the troubleshooting section, which has some settings to survive connection closures and setting the SetBigStringTryClob property

* Firewall - make sure the machine Jira is on can see the Oracle db

* Permissions, double check the credentials being used to connect to the oracle db are correct (no typos)

* Make sure you have the compatible version of the oracle jdbc driver (compatible with verison of Java/Jira and Oracle)

* Check the url connection string

* Double Check the ATlassian Guides

Hope that points you in the right direction
