Two same ORacle SIDs in one box

in Database Administration (MOSC) 8 commentsAnswered

Hello,

I use Oracle 11.2.0.4 SE and want to migrate to Oracle 19. Currently I use the same SID for both:

etc/inittab:

orcl:/opt/app/oracle/product/19.0.0/dbhome_1:N

orcl:/u01/app/oracle/product/11.2.0.4/dbhome_2:Y

The reason for this is that after migration we want to use the same connection string.

I know that thiss is not recommended but looks like all works fine when both instances are running. Can you confirm that I can leave as it is for the migration time. Can I expect any issues with such configuration ?

Howdy, Stranger!
