O & M specifications: During write operations, do not open two securCRT windows connected to different hosts.
This article describes write operations. For query operations, you can open only the securCRT window of one host, and do not open the securCRT window of the two hosts.
Because the data in a single table needs to be re-synchronized in the ogg replication environment, I often expdp IN THE ogg source database in the production environment and impdp IN THE ogg destination database.
When I expdp in the ogg source database in the production environment and scp the dmp file to the target OS, I will immediately exit the securCRT window at the ogg source.
The reason is that I am afraid that the drop table operation before impdp will be mistakenly pasted on the ogg source database for execution.
No matter what the situation, be careful.
I still remember the first time I read the <Oracle DBA Manual 4 data security warning list> written by guobiang (eygle), I was so scared that I had a bad night and had a bad dream.
Because, remember:
Oracle Database DBA for Oracle Database is the hospital surgeon for patients on the surgical platform. We always need to maintain a strong sense of responsibility for production safety !!!
