Hello All,
There is always seems to be a confusion in understanding the concepts of Qualified and Unqualified SSA's and Qualified and Unqualified calls. Can some one take time to explain the concepts with examples.
Thanks,
Vinadha |

Hi Vinadha,
Unqualified SSA: It specifies the SEGMENT TYPE the program is interested in. Here you don't indicate a particular occurrence of a segment because you don't care which occurrence of a segment you get.
It'll always extract first occurrence of the segment.
Qualified SSA: This is addition to the SEGMENT TYPE, also contains one or more qualification statements. A qualified SSA describes the segment occurrence a program wants to access.
It'll extract the occurrence matching with qualification provided.
Get back in case it is not clear...
Regards,
Priyesh. |

hai vinadha..
hope these clarifications help you:
qualified call:
A call that uses one or more SSA(Segment Search Arguement). A SSA is a particular way to access the DB by specifying the segment in which we need to look for.
Unqualified Call:
An unqualified call does not have any specification of SSA.
Qualified SSA:
A qualified SSA is a mean to look into the DB by specifying the segment and also the particular occurence with in the segment.
Unqualified SSA:
An Unqualified SSA does not mention the particular occurecne of the segment. Instead it mentions only the segment within which need is to look.
corrections welcomed...
