Re: [foxboro] I/A Batch Unix to I/A Batch Windows

David and all I/A Batch users,
Last february we migrated from rel.8.0 under Solaris to rel.8.1 under Windows.
We prepared the migration in detail, with many checkpoints as we manage >600 
recipes, under a "large" IABatch licence.

Briefly, this is our experience:

1) ModelDB, IALinkDB and RecipeDB (still Raima based) need to be converted. 
A recipe conversion tool is not offered by Invensys (it is for internal use 
only): so we paid the conversion as a consultant activity.
2) If you have developed some "C" programs based on Raima ToolKit, you need to 
rewrite as new "COM" libraries are different, based on ActiveX. No conversion 
is possible. Even with NutCracker. 
3) Some tuning done on EnvDisplay parameters (and on FoxAPI too) due to 
read/write tags timing issue. 
Our case: when a recipe writes a tag (CP linked), you can read it updated only 
after 1-2s; otherwise you must insert some "wait" transitions in the recipe.
In december 2008 we moved from CP40(FT)/AW51E on nodebus to CP270Z(FT)/P90/P92 
on the Mesh, leaving IABatch on a Solaris AW51E (Nodebus side with ATS): with 
this intermediate configuration, no read/write problems occurred.
4)IALink: it was impossible to configure a bit >9 for a CP tag, now there is a 
QF to solve it.
5)BatchDisplay: great flexibility now offered by zoomable SFC elements and 3 
recipe layers on full sizeable windows!
Jump functionality is still available and working well, but it is less flexible 
than before.
6)apart the usual care when you modify the code of a sequence in held state 
(restart it after CP checkpoint is completed), I noted that BatchManager 
crashed when operator started a new batch, where the first phase/sequence in 
the recipe was changed and CP checkpoint not yet finished. 
Ugly, as it required a stop/restart of the whole Runtime tasks. 
Luckily, hot restart feature works fine as in rel.8.0.

All the remaining features are kept: the feel & look is based on Windows, but 
the speed is significantly better.
We don’t have yet a development platform to play with IABatch in more detail; 
we played enough on the real platform in the second half of 2008, when still 
off-line. There are some feature we don't use as we don't know in deep...

Subject: [foxboro] I/A Batch Unix to I/A Batch Windows

Hello all,

We are in the process of moving a fairly current and working I/A 
Batch system from Solaris to the I/A Batch system on a windows based AW.

Any potential problems or pitfalls that we need to be aware of?

regards,
David
