APEX GANTT charts: restrict the hours displayed each day to only business hours (07:00 to 19:00) when no data found

ajmlrJan 8 2025

I have an APEX GANTT chart which displays the start/end time (APEX vsn Apex 24.1.6)

Im am always wanting the chart to display between 7am and 7pm for today.

This works fine when data is found, by configuring the APEX GANTT chart's setting of Timeline:StartDate EndDate to use values from my query.

However if no data is found for the chart, it defaults to show an empty chart (fine) but with the horizontal time axis of "now" to "now plus 24hrs", ie showing all the hours over midnight.

*** How can I configure this to default to "7am today" and "7pm today" in all cases, whether data is found or not?

Check the error reported in “Control panel→System and Securities→Administrative Tools→Event Viewer” under Windows Log→Application.

How did you set the Instant Client path in PATH? In command prompt?

If you have set it in a command prompt, then make sure you start that command prompt as administrator (i.e. opening it by right clicking on command prompt icon and select “run as administrator” from popped context menu). Also, you should start ODBC data source administrator by executing “odbcad32” from that command prompt. Have you?

Yes I started the cmd as run as Administrator.

I am using ODBC 64 bit not 32 bit.

I set the path using Windows UI (System properties), and if I open a cmd window and type set I can see the correct path.

starting “odbcad32” from the command line did not help.

I tried the same process on a different computer and got the same results.

odbcad32 is for ODBC 64 bit on Windows x64 versions. You need to start odbcad32 from syswow64 directory to configure ODBC 32 bit on Windows x64 versions.

Have you checked the Application error logs in Event viewer? Did you find any error related to your ODBC application?

pczurak-JavaNet Oct 16 2024

I am running the 64bit version, if I start odbcad32 from syswow64 it starts the 32bit version.

There are no errors in the Event Viewer.

I have tried basic driver version 19.24, but when I click on the Test button, I get the following error:

---------------------------
Testing Connection

[Oracle][ODBC][Ora]ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

Looks like the service name is missing in your connection string.

Here is a sample of connection string:

sales=
(DESCRIPTION=
(ADDRESS= (PROTOCOL=tcp)(HOST=sales-server)(PORT=1521))
(CONNECT_DATA=
(SERVICE_NAME=sales.us.acme.com)))
The part that is highlighted with bold characters seems to be missing in your connection string. Fix it.

This is what I am using.

JDEPRD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = testoda0)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = jdeprd.test.com)
)
)

Are you able to connect to your database using SQL*Plus?

pczurak-JavaNet Oct 17 2024

No:

F:\instantclient_23_5>sqlplus

SQL*Plus: Release 19.0.0.0.0 - Production on Thu Oct 17 07:55:39 2024
Version 19.24.0.0.0

The issue is fixed

In the ODBC Driver Configuration.

For the TNS Service Name you cannot type the name even if you type it exactly as it shows in the dropdown, you must select it from the dropdown, otherwise it won't work.
