  • by


Tried to show the property value of a database in data guard broker, but it failed with ORA-16606.

DGMGRL> show database ORCLSTB LogApplyStatus
Error: ORA-16606: unable to find property "logapplystatus"

ORA-16606 means that the property name you specified in the command is not valid. You should check the syntax or provide a valid one.

There're two error patterns of ORA-16606 in this post.

Non-existing Property

The first error type is that you provided a non-existing property. In the above command, there's no such LogApplyStatus property in data guard broker valid properties.

The following property StaticServiceName is invalid, too.

DGMGRL> show database ORCLSTB StaticServiceName
Error: ORA-16606: unable to find property "staticservicename"

Syntax Error

The second error type of ORA-16606 is syntax error. For example:

DGMGRL> show database ORCLSTB verbose
Error: ORA-16606: unable to find property "verbose"

To show database verbosely, we should put the database name to the last position.

DGMGRL> show database verbose ORCLSTB
