Q What are they?
A Looks like tables that were dropped and preserved in the RECYCLEBIN.
Q Is there any way I can get rid of them ?
A You can use e.g. PURGE TABLE BIN$GGrKjbVGTVaus4568IEhUQ==$0 ;
to remove them.
That will do them individually. Note that indexes and LOBs (and other out-of-line storage) may also have entries in the recycle bin. There are other statements you can use to clear out all entries from the recycle bin.
Q Or do I have to just deal with it and work with it?
A That's up to you.
There are statements to purge the recycle bin for the current user, or if you have privileges, for the entire database. You can also disable the recyclebin, or ( I think) there's an option on the DROP TABLE
that will drop a table without keeping it in the recyclebin (so these won't be created in the future.)
There's no need for me to repeat the contents of the Oracle documentation.
