Extended Segment Size
Required Change
•
If your programs reference data beyond a segment’s logical limit, eliminate these
references.
Extended Segment Size
The operating system defines the maximum size of an extended segment to be 127.5
MB (%0776000000D) on both TNS and TNS/R systems. Previous releases of the
operating system defined the limit to be 128 MB. The ALLOCATESEGMENT,
SEGMENT_ALLOCATE_, and RESIZESEGMENT system procedures no longer
allocate segments larger than 127.5 MB.
Detection Guideline
•
If your programs allocate segments larger than 127.5 MB, ALLOCATESEGMENT
and SEGMENT_ALLOCATE_ return error -2.
Required Change
•
Change your programs to use the new maximum segment size if they allocate
segments larger than 127.5 MB.
