Scheuma_upgrade error

[atsflex]

 Upgrade failed. Please consult the system logs for details. You will need to fix these problems, restore your database and confluence home directory to the pre upgrade state. Then retry the upgrade. Upgrade error message: Upgrade task com.atlassian.confluence.upgrade.upgradetask.DropSpaceGroupTablesUpgradeTask@15058912 failed during the SCHEMA_UPGRADE phase due to: null

i am running Oracle, why am I getting the following error?

Nik,

This appears to be the issue described in this article:

• Upgrading to Confluence 5.9.x or 5.10.x fails with error 'failed during the SCHEMA_UPGRADE phase due to: null'

Could you have a look there to see if it applies to you? If not, what version are you upgrading from and to?

Shannon, 

Thanks for responding.  I realize why it was failing, our database was getting hung from loading.  I had to restart the database with the install and patiently wait for it to be completed.

Thank you for letting me know, Nik! So you can confirm that the issue is now fully resolved or you?

Regards,
