DE 6.52 Forms limit

Postby Stewart Allen » Wed Mar 30, 2011 5:15 pm

Is there any way to increase the maximum Forms(Tables) limit in DE 6.52?
It is currently limited to 1000.

Not aware that there was a limit, nor (obviously) a way to increase it.

But aren't you using SQL for some or all of your data? I know your domain is complicated, but could you not consider having several applications rather than everything in a single 'box'?

Out of interest, how does the limit manifest itself?

Hi Adrian

We already do have different applications (DE and Oracle Forms client server and WEB), with data in native DE and multiple Oracle db's. The largest 'application' system is still a DE 6.52 app.
Too much trouble to move everything that already works. Once we moved to using terminal server, the DE WAN performance limitations became irrelevant.
The only real issue is that there is also no way to read data in DE6.52 tables from anything else or even from a different DE app from DE 6.52 tables. As a result the primary user app is a DE6.52 app which writes/reads data in DE/Oracle.

DE reports an error: "Tables limit(1000) exceeded" if an attempt is made to :
1. create a new native DE table manually or
2. create a new DE table with a DIW install or
3. build a form on a new Oracle table.

An old forum post from Fred relating to 5.16 DOS and relationship limits suggested editing the ZTERMDEF.DBZ - can anything similar be done for the tables limit on DE6.52?

Seems i will have to some housekeeping to keep everything under 1000 or change priorities and move everything ASAP.

Not surprisingly there is no reply from the DataEase forum.

There is indeed a 1000 table limit in DFW. The good news is you can have as many documents as you like.

Hi Pete

Having unlimited forms does not help as this also limits use of external SQL tables.

Is this limit hardcoded by choice or due to resource limitations?

Is there any way to adjust this limit?

There is no way to adjust this limit in DataEase. At least, not in the versions I know about. There were internal variables and so on that prevented it being significantly larger.

In Ffenics the limit is 32000. (1024, 32767 - you get the idea :-) )
