Primary Dataset   (Dataset)

DESCRIPTION
"Primary Dataset" displays the name of the primary dataset for an alternate
index chosen from the VSAM Screen. The name of the clicked dataset appears 
beneath the title icon.


VALUES
The "Primary Dataset" name consists of one to eight characters. When the Dataset
Screen is for an alternate, Sun MTPScan obtains the name of the "Primary Dataset" 
for the alternate from the Sun MTP File Control Table (FCT), where it is defined 
by the administrator. When the Dataset Screen is for a primary, the value is
'Self'.


INTERPRETATION
When you click on a primary dataset on the VSAM Screen, the resulting Dataset 
Screen shows the "Primary Dataset" as self. The actual name of the primary
appears beneath the title icon. For a primary, all entries in the two 
KxScrolledLists are for that "Primary Dataset".

When you click on an alternate index on the VSAM Screen, "Primary Dataset"
identifies the primary for the alternate. Note that the two KxScrolledLists do 
not contain entries for an alternate index. Click on the alternate's "Primary 
Dataset" on the VSAM Screen to see how a dataset is segmented.


CONCLUSIONS
Problems with alternate indices usually originate from misconfiguration of the
"Primary Dataset". Refer to $KIXSYS/unikixmain.log for error messages about
datasets.
