    PSAPTEM might not have been used because it was not necessary to use it. Why is it a problem?

    did you created an index that did not fit in the PGA? I assume not.

    did you executed something that oracle thought needed to do a HASH JOIN and it did not fit in memory? I assuem not.

    did you executed something that oracle thought needed to be sorted and did not fit in memory? I assume not.

    et cetera.

    then you said you generated SGEN and PSAPSR3740 grow.

    Do you know what SGEN does?

    Do you know what tables in PSAPSR3740 have grown?

    again, I have took at the crystal ball and guess.

    SGAN takes the SAP ABAP source code, compiles it and saves in the database the compiled version, that way it is not compiled the first time you executed someting.

    As mentioned, "saves in the database" something, therefore, the database increase the size.

    I would check the size of the table REPOLOAD (and its associated lob segment) and you will see it.

    Then it would be quite difficult to "reclaim space"

    but, you now, I'm guessing
