GOAL:
Can a Progress 9.1D Client connect to a Progress 9.1D database and a Progress 9.1E database at the same time?
GOAL:
How can a Progress 9.1E 4GL Client connect to a Progress 9.1D database and a Progress 9.1E database simultaneously?
FACT(s) (Environment):
All Supported Operating Systems
Progress 9.x
FIX:
1. Yes, a Progress 9.1E 4GL Client can connect to a Progress 9.1D database and a Progress 9.1E database at the same time and vice versa. This is because both the 9.1D release and the 9.1E release are minor releases of the same major 9.1x version. In general, when working with two minor releases of the same Progress Version, either release's 4GL client can connect to either release's 4GL database with no problems.
2. Such connections may be established in one of three ways, using the data dictionary, using the 4GL CONNECT statement or using the progress session?s command line.
The following sample connections may be established using either a 9.1D or a 9.E client. These samples demonstrate connections established using the 4GL CONNECT statement and the Progress 4GL client session?s startup command line:
A. Connections using the CONNECT statement:
A.1 Specify all the connection parameters explicitly in the CONNECT statement:
CONNECT
C:\wrk91E\sports2000
-ld my91Ddatabase
-H pcyshanshi1
-N TCP
-S 9999
-db C:\wrk91E\sports2000
-ld my91Edatabase
-H pcyshanshi1
-N TCP
-S 8888 NO-ERROR.
A.2 Reference a parameter file .pf containing the connection parameters:
CONNECT
-pf C:\wrk91E\myparamfile.pf
Where myparamfile.pf contains the following data:
C:\wrk91D\sports2000
-ld my91Ddatabase
-H pcyshanshi1
-N TCP
-S 9999
-db C:\wrk91E\sports2000
-ld my91Edatabase
-H pcyshanshi1
-N TCP
-S 8888
B. Connection from the command line:
B.1 Specify all the connection parameters explicitly in the command line:
C:\Progress91E\bin\prowin32.exe C:\wrk91D\sports2000 -ld my91Ddatabase -H pcyshanshi1 -N TCP -S 9999 -db C:\wrk91E\sports2000 -ld my91Edatabase -H pcyshanshi1 -N tcp -S 8888
B.2 Reference a parameter file .pf containing the connection parameters:
C:\Progress91E\bin\prowin32.exe -pf C:\wrk91E\myparamfile.pf
Where myparamfile.pf contains the same data as described in 1.2 above:
