Single eloqdb6 volume is limited to 2GB
The size of a single volume file for the Eloquence eloqdb6 database
server is currently limited to 2GB (as of A.06.10).
When a volume file reaches the 2GB limit, a database status
-803 is returned to the program. The server log includes
error messages about failed vol_Write() and vol_AllocPage()
operations.
Background
While HP-UX 10.20 and VxFS support larger file sizes, an additional
flag must be passed to the HP-UX when opening the volume file
and lseek64 must be used instead of lseek which is limited to 32 bit.
We currently use a single binary for all HP-UX revisions. Until
a separate binary for each OS revision is shipped for HP-UX 10.20
and above file sizes above 2GB cannot be supported.
Workaround
Since Eloquence supports up to 255 volumes a workaround for this
limitation is easy. Just add another volume file to the database
environment (using dbvolextend).
