Hi Hany and others,
I’ve noticed that the XER files are 13MB large, due to the so-called ‘POBS table’. This contains useless information and is probably introduced by Oracle for some dubious reasons… You can manually delete the table, or use a tool called Purge POBS which I’ve attached. This reduces the 13MB to only 200KB.
The files remain fully operational and don’t loose any information.
(ps. the latest versions of P6 don’t create these tables anymore)
Hope this helps,
