[5] Over time, IBM started to provide service aids such as IMAPTFLE[6] and utilities such as IEBEDIT[7] to simplify the installation of batches of PTFs.
In some instances IBM will release a "Cumulative PTF Pack", a large number of fixes which function best as a whole, and are sometimes codependent.
When this happens, IBM issues compact discs containing the entire PTF pack, which can be loaded directly onto the system from its media drive.
"[9] If the "Cumulative PTF Pack" is larger than the default, "If you try (to) FTP 17GB of ISO images you will run out of space."
However, if no problems are found after the service is applied, it can be permanently installed, ACCEPTed (committed) to the system.
It is generally expected by the customer that the problem would be fully corrected in the next release (version) of the relevant product.
