On January 29th, 2019, zabbix displays an index tablespace alarm, so log in to the server to see:

10:02:22 SQL > col file_name for A50

I was confused at a glance. I didn't know who was adding the data file before, but the name was wrong. Fortunately, this is a set of 12.2 databases that can rename data files online in the same way as moving data files online. A previous blog post briefly introduced:

Let's change the data file name with this method.

10:05:03 SQL > alter / * source only*/ database move datafile'/ u01qqqoradataDLOGHelp tbsspuunvidx03.dbf'oradata'/ u01Grex03.dbf' / u01qqr SQL > alter / * oradata'/ u01qqr

Oracle database has never been a road to Huashan, but all roads lead to Rome, the solution is also very simple, it is possible to specify file_id.

10:14:09 SQL > alter / * source only*/ database move datafile 19 to'/ u01 apprenticeships oradataUniplicateDLOG Greater tbsroomlogix03.dbf'

You can see the locks added by this process through toad

It's still a long time.

Finally, the problem was found when the mouse was selected in CRT.
