Reduce the job database size before upgrade
The job database is now cached in memory in web services. Following an upgrade, existing VMware and Red Hat Virtualization (RHV) jobs are assigned an asset namespace to enable access control at an asset level. This process may take some time. You should reduce the size of the jobs database before upgrade to minimize the amount of processing required to perform the association and minimize the effect on web services performance. Very large job databases may see an alert regarding high heap space usage. For details on reducing the size of the job database or increasing the maximum heap size for web services, see the following article.
