It is advisable to test the steps on Test environment first before moving to Production environment. So need to drop/add redo log in order to change the size. You should be following the each steps for error free recreation of redo logs. (11) The same is true for redo log file member.
(10) Repeat the same for all redo group and get all the redo recreated (9) Create the new redo group using alter database add logfile group alter database add logfile group 1 ( (8) When the group is Archive=Yes and Status=Inactive, then you can drop it in your command session using alter database drop logfile group alter database drop logfile group 1 (6) If the group is something other than Archive=Yes and Status=Inactive, then you need to rotate it.So run alter system switch log file Ĭheck again,if it is not Archive=Yes and Status=Inactive then run againħ) Then again run the above command select l.thread#, l.group#, l.archived, l.status, bytes/1024/1024 MB The line parallel to the axis intersects the graph of the logarithm at the point with coordinate. The parallelogram adds the logarithms of and. how the logs are stored / indexed, see: Adding Custom Transports) to the API that they exposed to the programmer. Run the following sql to check the status of Redo logs select l.thread#, l.group#, l.archived, l.status, bytes/1024/1024 MB Fullscreen Drag the orange locators with coordinates and.
