Migrated Database from Oracle to Oracle Cloud

[kvca11]

Hi Team,

we have migrated database from Oracle 12 c to Oracle cloud and doing the reports validation,we are facing an issue with one of the report,ie.Report is keeping on running more than 2 hours and getting failed failed after sometime in cloud and same report is running in 20 mins in oracle 12c

Let us know what are all things we can do at report level after database migration,is it comes under environmental issue (report is built based on sql)

Thanks,
vck
