Ensuring that you have enough transactional log space for an upgrade
Before upgrading, ensure that 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, for which adequate transactional space is required.
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.
To ensure that you have enough transactional log space for an upgrade
- 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 ensure that 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.)
