There has been an error processing your request

Not know how to roll back because I did not get backup as they says it is stable, or not able to resolve this error.

Answer 1

Delete the contents of var/cache/

For the future, remember to turn off Compiler, all Indexes, and all Caches prior to performing an update.

What happened, is that the configuration cache is still active, and prevents Magento from detecting that database changes are necessary.

Answer 2

The issue is caused by a missing column named: is_percent in the table catalog_product_entity_group_price

Magento 1.9.3 includes an upgrade file that creates that column in the database. The file is located here: app/code/core/Mage/Catalog/sql/catalog_setup/upgrade-1.6.0.0.19.1.4-1.6.0.0.19.1.5.php

When the cache is enabled the installer can’t run the upgrade script, causing the error reported by the OP. Another possible cause of a failed upgrade script is if you refresh the frontend or backend before all files have been uploaded via FTP.

If flushing the cache doesn’t solve the problem (be sure to refresh any external cache like Redis) you can try the following:

1) Open the core_resource table

2) Locate the catalog_setup row

3) If the current value for version and data_versions is: 1.6.0.0.19.1.5 then change both values to 1.6.0.0.19.1.2 and refresh any page of the frontend.

This will force Magento to rerun the upgrade script and create the missing column in the database.

If the value for version and data_version is 1.6.0.0.19.1.2 then you are not properly flushing the cache.

Answer 3

Delete all files/folders from the folder path "var/cache/"

And make sure you disabled caching before start upgrade.
