Applyptf eliminates common PTF application problems:
* Verifies prerequisite PTFs have already been installed
Applyptf scans through the node's "history file", a log that lists what PTFs have been applied (and when) by this application. If no such log exists it offers to create one and will name it "<nodename>.his".
More information on history files is included later in this document.
* Compares the file dates in the PTF with those already on the target
Applyptf compares the date stamp of all "replacement" files in the PTF with those already on the system. It will not replace a file if it detects that the new file is older than its installed counterpart.
* Backs up the original files in case you need to remove the PTF
Applyptf creates a directory tree "REPLACED\PTFNAME.OLD" on NT, and "REPLACED\PTNFAME" on Unix, in the target component/image directory. For example, for a Unicenter TNG Worldview fix it may create "c:\tngwv\replaced\lo76563.old". For a master install image it may create
"c:\tngimage\replaced\ lo76563.old". It then copies all original files that will be replaced to this directory. It will not overwrite any file already in this directory, thus not overwriting any originals if the file is replaced again in a later PTF application.
* Maintains a PTF history file for each PTF application target
Applyptf will update the target's history file each time it applies a PTF to it.
* Seamlessly performs all of the above actions from a single node
The Applyptf Wizard can be run from any Windows NT node. There is a Unix version of Applyptf as well.
Be sure to review the installation instructions included with each PTF ---before--- using Applyptf to apply a fix to any system. (Some fixes may contain instructions about steps that need to be completed before or after a fix is applied.)
