After numerous attempt to simulate and reproduce the problem encountered, we failed to create a test case of this error.\n\nRecommendations:\n1. After running an alter table make sure to run the following\n\ta. usermod dbname [-uusername][{table1 table2 table3 ...}] [-noint] [-repmod [+w|-w]] [-online].  This is to modify the table/s being altered.\n\n\tb. ckpdb dbname.  This is so that the physical structure of the table match the journals.\n\n\n2. We also strongly recommend to update the patch on this server and on any other production servers to avoid these kind of problems happening in the future.  We are currently on II 11.1.0 (a64.lnx/100) 15744 as of April 2022.\n\n\n
