Making sure you have enough transactional log space for an upgrade
Before upgrading, you need to make sure you have enough transactional log space for the upgrade. During the upgrade, production dataset record data is copied from the BMC Atrium CMDB BMC.CORE:BMC_BaseElement form to a new AST:Attributes form. Because of this, make sure you have enough transactional log space as outlined in the following procedure.
Data update jobs are run for all applications, so complete the following procedure even if you do not plan to use the multi-tenancy feature.
- Determine the largest BMC Remedy AR System database table based on the application forms on your system.
- Calculate the transaction log space required to support the largest table (plus a 20% buffer), and make sure you have sufficient space before starting the upgrade.
Use the new value to set the size of the database transaction log or undo tablespace. (Hint: Update the UNDOTBLSP setting.)
