Thanks RB / Deepak,
So moral is I should not change the class SSEXC to APPL0 and migrate all tables to PSAPSR3731 with below command.
brspace -c force -o process,time -u / -f tbreorg -a reorg -tablespace PSAPSR3700 -t "*" -parallel 3 -degree 3 -newts PSAPSR3731
I have one more doubt here is, Once I drop the tablespace SAPSR3700 with data and contents, will the space be free on OS file systems ?
I read somewhere that it doesn't free the space at OS level. Please suggest what we need to get the space free at OS level.
We are using AIX 6.1 & Oracle 11.2.0.3.
Regards
SS
