507.0. "Focus & Ultrix & Ingres ???" by EEMELI::RAISKINEN () Mon Apr 13 1992 04:08

    
    Anyone out there willing to comment on this....
    
    
    The local Unilever has been a Focus user on VMS/Rdb environment and
    now they are moving to RISC/Ultrix environment. The would like
    to continue using Focus and of course they'd like to have access
    to their old Rdb data. Since Focnet is not available on RISC/ultrix we
    have suggested the following configuration:
    
    
    	Ultrix-box                     VMS-box
    
    	Focus                          Focus
    	Ultrix/SQL                     Ultrix/SQL remote access to rdb
    	Ultrix/SQL Net                 Rdb
    	DECnet                         DECnet
    
    The general idea is to use Focus and Ingres on Ultrix and use remote 
    rdb databases as if they were remote Ingres databases.
    
    I have managed to configure the system so, that i can access the
    remote Rdb databases from Ultrix/SQL environment with isql
    (interactive sql), but when i try to use focus (for example tabletalk)
    the connection fails with an error message saying that cursor
    operations have failed. The logfiles on VMS show that the query have
    reached the Rdb - database,  everything seems to be OK. The local
    Information-Builder office claims that the configuration should work
    they have checked the .mas .focsql definitions and they are OK.
    
    Any hints ?
    
    I'm using
    
    Ultrix 4.2
    Ultrix/SQL 2.0
    VMS 5.5
    Rdb 4.0
    Remote Access to Rdb 1.0
    
    cheers,

	I haven't try this configuration, nor do I have much experience
	with Ultrix/FOCUS, however here are couple of tips, hope it might
	be helpful :

	1: Did you try to FILEDEF the FSTRACE in order to trace all cursors
	   operations, and see especially the offending return code and
	   SQL operation (Probably SQL Connect)

	2: I know (that on VMS) there are two settings in Ingres for error
	   messages processing when accessing foreign (RdB) databases :

	   - either to return the underlying database error code.
	   - or return a generic INGRES/SQL error code (This mode should
	     be preferred since for FOCUS things should look like it's
	     trying to access to Ingres and has no idea that RdB is
	     underneath)

	3: Finally I suggest to check how the username/password is being
	   passed to Ingres (and then RdB).

Cheers

    	To be continued...
    
    	The local focus representative told me the configuration described
    	in .0 is a no go with the current Focus version. However, there is
    	going to be a new release (version, patch,..??) soon where .0
    	should work. Could anyone verify that, is it a patch or a new
    	version.
