Folks On an internal Test 10gR2 Database running of CSALTER.plb is Failing when Attempting to Alter Character Set from US7ASCII to AL32UTF8. Qs Does User/Application Data which during CSSCAN reported 2 types of Errors i.e. "Truncation" & "Lossy conversion" necessarily needs to be Manually Corrected? NOTE - We do NOT seek to Manually correct the Application Data, but want CSALTER to go thru successfully. Qs Should the 3 indexes which need to be RE-built be DROPPED before Running the CSALTER.PLB Script & RE-built After ALTERATION? Application = Banking Product O.S. = HP-UX B.11.11 Thanks indeed Vivek OUTPUT of CSALTER.PLB:- SQL> start ?/rdbms/admin/csalter.plb Checking data validility...
