UCS on Oracle DB

Hi guys,
wondering if any of you had this scenario already on Oracle.
UCS has two tables with BLOB objects (IXNContent is one for example). This table creates another object which sucks DB available space by creating an object of type:

SYS_LOB0000087624C00004$$

I followed:

to try to shrink space (object has 19Gb but uses 3Gb only…) but didn’t work…customer DBA is also not familiar with these problem and Genesys is trying me to just get more space…yeah…it is free for them

Has anyone came across with this issue before?

Any suggestions?

Thanks!

Which Oralce version that you use ?

What is the step that you stuck ? Is it has any error message ?
