sql server 2008 - How to use the rollback using multiple database updates in oracle? -


i want update multiple databases , each database contains multiple tables. if problem occurs want rollback databases , tables original state. can give me 1 suggest can this? thank spending time read question.

you need program connect databases @ once , initiate lock on tables getting updated.

apply changes , in event of exception, rollback current database , completed databases.

the aim keep 1 session in sync on databases - not pretty thing do.

your other option see if can configure 0 downtime install. break install sections - can applied first, can applied after.

i.e. can add column tables (hopefully) without issue pre-install. can not remove column until no longer consumed post step. involve having multiple versions stuff views , packages allow application transition without impact.
