Hi, maybe lame question but is there a application outage during the switchover? Thanks
@@majojepan9 Hi, Yes, DB sessions will be disconnected, however, if application can reconnect automatically to the new db without letting users feeling this you may consider it as no disconnecting. Mainly I consider it as interruption.
Please share the command which u had in notepad. It will be useful
@@swethaswetha8966 I will do this in future lab, thanks
Thank you for this. Been struggling with the installation. Will this method work on Redhat 9?
@@kunihiramuchwa actually it's works put you have to patch for certain level during the installation and perform the prechek I will do one video for this soon
Very good explanation.
can you show how to do it using oracle data guard broker? in oracle 21.3.0, I face this error: DGMGRL> failover to orap; ORA-16600: not connected to target standby database 1. My tns's are correct. 2. I am connected to the secondary database and trying to do failover.
Assalamu-alaykum brother, Nice explanation. Would like to check with you. Is the user creation mandatory before import ?? Let's say user belongs to the tablespace that i am migrating currently.
Hi, Create any users in the destination database that owned objects within the tablespace being transported before importing the Metadata.
@salmanlab87 The default user table size is 1 GB. But the user size is around 1 TB. The tablespace contains all the data of the user which is 1 TB. In this case the user tablespace requires 1 TB or 1 GB should be enough?
@@zubairwali222 size will be the tablespace size that you configured to move
When taking l1 backup, for source database, is it required to have L0 backup file in the src_backups destination
@@zubairwali222 file will be created on this path and then you have to move it to the destination path to apply it
Good Job Salman , way to go brother
Thanks Samer
Hello sir, After performing switchover, how users will connect to primary database. Do we need to provide any information to them.
Thats depends on connection type If it is tnsnames you may change it or configure it to cover both If network nat or dns in the middle you may change there
@@salmanlab87 thank you very much
Hi, On doing switchover in 19c , it completes successfully but if I do show configuration afterwards , it gives the same apply lag error which you got. In your case it got resolved in some time, but in my case it doesn't go away automatically , it persists. Please suggest what could be the issue.
Hi Check the logs for the details, seems that missing configuration on the standby . Start with connecting from standby server to the main server db and reverse.
I am facing error in configuration error [DBT-50000] Unable to check for available memory how to solve this error
Share the full details pls Where this error appeared ..etc
Excellent presentation! I shall upgrade a test 12.2.0 instance along with its standby to Oracle 19.22 now.
thank you so much .
Very helpful video 😊
Can you share your installation file/document?
I always refer to oracle official documents
You missed to run "select * from dba_registry_sqlpatch;" in database at the end to check the status of patching in database.
That is true. You may run this to verify the data patching
Unable to find a match: libnsl2-devel? Any solution plz?
Ensure that os repository is configured with right version. If you got error while installing it please share it .
@@salmanlab87 I use Centos 8.
Excellent work your doing.. please keep posting videos and sharing your knowledge with us... Thanks ❤

Thank you so much
Thank you
Did you try this ever with switch over to allow zero downtime? I came across to see the same. Thanks by the way for putting the time here.
As you know patching is two steps. Binary patching and data patching. With DG you will do only Binary patching,thus, switchover will not leads to zero downtime. Only rac is rolling patching with interruption actually while stop one node
Hey bro will you help me to create a oracle account I don't have credit card
Yes I will.
nice video ! thanks
