Types of code fixes

There are four types of code fixes

1. Code fixes applied to the i5/OS™ integration code, referred to as regular program temporary fixes (PTFs).
   • To apply them all you have to do is install them to i5/OS.
   • These code fixes are available from IBM® Support or from the internet at http://www.ibm.com/servers/eserver/iseries/integratedxseries (take the Service & support link on the left navigation bar) .
2. Code fixes which are copied to the integrated server's drives and run on the integrated server, referred to as service pack PTFs.
   • The IBM iSeries™ Integrated Server Support licensed program has an integrated server part which is copied over from the i5/OS side. When you apply an i5/OS Cumulative PTF package, it may contain an Integrated Server Support service pack which can be applied to the integrated server. You do this by synchronizing the integrated server.
   • These code fixes are also available from IBM Support or online at http://www.ibm.com/servers/eserver/iseries/integratedxseries/ (take the Service & support link on the left navigation bar) .
3. Code fixes applied to Microsoft® Windows server itself, referred to as service packs.
   • These come from Microsoft. You can download them from their Windows Update web site.
   • Do not apply any code fixes from Microsoft which might change portions of Windows server used by IBM iSeries Integrated Server Support. For example, do not download any SCSI storage device drivers or LAN device drivers from Windows Update.
   • Other areas are generally safe, for example, USB device drivers may be downloaded from Windows Update at your own risk.
4. Hotfixes applied to Microsoft Windows server itself and applied using Windows Update.
