Is RPG dead?

2012-05-20T12:59:53+00:00

Mel Beckman wrote at Iprodeveloper past April 16 that RPG is dead. Curious statement being Mel Beckman the senior technical director for iPro Developer. Do you agree? I wonder if it is worth to argue Mel's thoughts, given the case we are building server functions on RPG daily at our shops.

Only one fix, I must search for "Optional" in the target not "yes"! This will get all triples I need!

I noticed this after opening a local and edited my posting

a bit latter. with a local open...much easier. Do a usage in your model on the System value 'Optional'

I ran my app and it works but you have to make sure of permssions, Implmented triples are not an issue. Good luck

So happy to read this while having my coffee!

George, your suggestion but most of all your grid expample started me thinking about looking in the model for a specific string...and more...a new word is opening for me.
I was sure it is a simple thing for ones who are already confident with model api...

Only one fix, I must search for "Optional" in the target not "yes"! This will get all triples I need!

RE: Model API to delete Triples

2012-05-19T06:14:58+00:00

Early morning coffee and a brain wave

We are going about this the wrong way.

What you don't like in the model is optional continuation triples. How to we find them.

Well why don't you find all triples with target as system yes.

Then check its verb is it optionally

Then delete

This will save you the need to working it from the entity level. Working backwards as it where. I love a model API challenge and as long as the findobj does not blow up as it does have its limits this will be much much much easier, and now I have got to interested in this I will look at creating a little app if the wife allows me to on the weekend! Dam model API will be on the divorce papers.

Hi George

Blame me mr. It was my request :-). Works well and helps a lot on a couple of my projects where I need an enumerator of the entity as it is in the model and therefore it's subsequent generated state!

EnumObjAttributes

Awesome, god how CA support would have liked this last year after i bugged them to fix the meta to do the same thing over 6 months.

Model API to get all fields from an entity or view will be happy campers

Please Please Please can you or someone keep me updated on model api plans. These new apis will definetley be added to Stella Tools 3! Especially for object documentation i will now be able to auto generate documentation of function interfaces, view fields, Edited: or maybe not for function interfaces but still a great new api.

RE: Model API to delete Triples

2012-05-18T20:38:41+00:00

what is the 'customized DB administration tool'

does it accept sql server database schema, if so you could just build your local to config to sql server db.

These one offs are harldy ever one offs hence I wrote Stella Tools.

I previously said and Rob agreed you are going to have to be very acurate with the NAME and also knowledgeable about all the different scenaros of the optionality triple and how their NAME continuation triple would look like. While checking if the triple is inherited or not and you have permission to delete the triple etc.

I think if I was doing this I would use meta to kick off the model api process and thats all. Meta to get every entity name then into Model api world!

might even put something together..

RE: Model API to delete Triples

2012-05-18T19:19:47+00:00

Hi there Stefano,

Sorry - I just saw the post as a good Meta code challenge, I hadn't realized what you needed it for. I'm in agreement with George about mixing your meta with your PlexAPI - you may have to be just-so with your naming, and I could imagine you end up having to concatenate/format strings to pass to PlexAPI in order for it to work out what object you want to remove.

My preferred way of doing this type of batch change is using PlexAPI. Even if it is a one-shot tool, you'll probably find that if you keep it, you'll probably end up modifying it to mangle your models for some other reason in the future!

Furthermore, if you can wait until the next Plex r6.1 and r7.0 PTF builds, there are two flavors of a new PlexAPI method that could help you do this without having to delete continuation triples in a temporary model and generating a throwaway set of database tables. These are:

EnumObjAttributes
EnumSafearrayObjAttributes

When passed an entity, table or view object reference, these methods will return an enumerator of attributes (as field references) against that object, in the order that the attributes are displayed in the Attribute or View Editor and hence the same order that they are generated into the respective table or view for that object. As such, you can get an enumerator of all the fields for a given table or view, and then read the details about the field by making further PlexAPI calls against the field reference.

This would mean that you wouldn't have to jump through hoops trying to get your database tables generated in a particular way, and the tool could be rerun at a later date if you add more tables....

These APIs are fixed against problem CPLEX 1919 and will be in PTF610.043.034 and PTF70..038.001.

Hope this information helps (at the very least, I hope it doesn't confuse you more!),

-Rob

We are making a customized DB administration tool, that use SQL for DB definition also in iSeries (and Plex for iSeries generate only DDS). I want to import Entity definition from my Plex models into that tool by using .tbl sources generated by Plex.
To have the correct definition in the target environment I need to have all costraints generated, and when a relation is optional costraints are not generated. Here is the need of this post.
After obtaining all tbl sources I will not update my group models. This is a one-shot utility.

I don't know if I was clear enough...

Thank you,

RE: Model API to delete Triples

2012-05-18T17:12:25+00:00

few more tips with model api.

the plex message log is your friend, it will tell you like if you were trying to delete triples in the browser and there is an error the maority of cases

put to a grid what is happening, ie the triple you are going to delete etc, as this rountine you are creating will fail over 4600 entities for various coding reasons which you will need to fix but you dont want to be debugging so handy to see what triple is busting the rountine,

check the call status and get error message using the exposed api

A question for you: Why are you doing this? Has all data modelling relationships suddenly become mnadatory?

Thank you George,

what I need to do is to delete in a model all "optionality" triples. It is my first try with model API and it's the only way I know to avoid deleting triples manually on 4500 Ent.!

If you have an easier solution please share it, I will be happy to learn new tips!

You are right, my code does not get the correct name of the triple, I'm currently getting the name correspondig to the basic triple, not the continuation one...

Stefano

RE: Model API to delete Triples

2012-05-18T14:05:10+00:00

are sure youn are sending it the correctly formated NAME of the triple. Consider the attached picture that illustrates the actual name in the model of an optional refers to relationship to the surrogate entity by my own 'MyEntity'

Mixing meta and model api can be fun but you must remember on the design front one is at runtime and one is at generation time.

If you descibe what you are trying to achieve I might have an easier solution as you are going to have to be very accurate with your trople NAME to get your current method ot work at all, I have not tested FindObj with find triple by name...you never know it might not work currently and will need a runtime fix etc

Ok Rob,

Now it seem to work! I had to change the +for each property ENT has FLD loop to +for each property without any verb becouse I'm looking for OwnedBy/KnowBy/RefersTo relations.

Thank you for the suggestion!

The correct code:

ª+1 +++Define Field: FIELDS/+Triple
ª+1 +++Define Field: +Object
ª+1 +For Each Object Entity
ª+2 +If Query Object Library
ª+3 Comment Skip object.
ª+2 +Else
ª+3 +++Set Value To Current Field: +Object
ª+3 ++Name Defined Field: +Object, Environment<*Object>
ª+3 Comment Environment<*Object> is now set to the name of the current entity.
ª+3 +For Defined Value Field: +Object
ª+4 +For Each Property
ª+5 +If ENT known by FLD/ENT has FLD ... optionality SYS, System: Optional
ª+6 +++Set Value To Current Field: FIELDS/+Triple
ª+6 ++Name Defined Field: FIELDS/+Triple, Environment<*Object name>

Post as Issue (case)

2012-05-17T20:34:15+00:00

Hi,

The communities message boards already give us the ability, on a thread, to 'Post as Idea'.

I'd like to see the ability on a thread to 'Post as an issue (case)'. i.e. an issue will be, semi-automatically, raised in the CA Support system.

e.g. Maybe taking the link of the thread into the issue description...and give our Support systems to auto-post back to the thread when an issue has been closed…maybe the owner of the thread could choose whether to post additional thread activity to the issue activity…that sort of thing.

I think this would be advantageous as more people would be able to see/contribute to an issue and its resolution, discussed in a forum thread...it might also save, at least. some of the double-maintenance overhead, e.g. in Beta programs when we allow customers to provide feedback via a forum, then in parallel we raise and maintain internal support issues.

RE: Model API to delete Triples

2012-05-17T16:51:39+00:00

Hi there Stefano,

I often find that the best place to look for inspiration is in the meta functions that are already shipped in OBASE and the META libraries. That lead me to this solution:

ª+1 +++Define Field: FIELDS/+Triple
ª+1 +++Define Field: +Object
ª+1 +For Each Object Entity
ª+2 +If Query Object Library
ª+3 Comment Skip object.
ª+2 +Else
ª+3 +++Set Value To Current Field: +Object
ª+3 ++Name Defined Field: +Object, Environment<*Object>
ª+3 Comment Environment<*Object> is now set to the name of the current entity.
ª+3 +For Defined Value Field: +Object
ª+4 +For Each Property ENT has FLD
ª+5 +If ENT known by FLD/ENT has FLD ... optionality SYS, System: Optional
ª+6 +++Set Value To Current Field: FIELDS/+Triple
ª+6 ++Name Defined Field: FIELDS/+Triple, Environment<*Object name>
ª+6 Comment Environment<*Object name> is now set to the name of the triple that has optionality set.

The main thing is the +If query inside the +For Each loop. To get the correct triple, I normally drag it from the AD Palette under Meta Operations/Queries/Properties.../Verbs... that avoids the pain of the AD syntax checker!

Hope this helps,

-Rob

Hi, Gianluca

I don't know Italian, but I can guess what the message says, like I can guess for English. (I am a Japanese.)

The compile error you get is due to mis-matching version between Plex.exe (generator) and Plex .NET runtime.
I assume you applied a PTF for Plex tool since GA. But you probably never apply the .NET runtime PTF.

So plese apply the Plex .NET runtime PTF with the same PTF build with your Plex.exe.

This should solve the problem you have.

RE: Consuming a web service in 2E

2012-05-17T04:59:03+00:00

Hi Simon

At this point we have 'consumed' web services from two other providers and are likely to add a third set in the near future.

The first use was adding a call to a remote system into our Point of Sale 2E application. This allows data validation and removes the need for users to double enter data into two systems. (We really shold be doing a lot more of this!)

The second (and likely third) use is where we are effectively replicating parts of our database to a different system. These systems are being supported by third party suppliers to our customer and need bits of database to work. We enhanced our journal monitoring system to allow it to call specific 2E programs when changes are made to specific files. These then pick up the data needed from the wider database and make the appropriate web service call.

We built RPGLE programs based on Scott Klement's LIBHTTP suite sample program(s). These handle all the messy stuff and we link them into the 2E application by defining them as user programs. The user programs end up having a nice and simple parameter interface - some input and some output parameters and a return code and error message parameters so you have some idea about what happenned inside the web service call.

I haven't had a need to use arrays when consuming a web service yet (I don't think I would - the reason for wanting to use an array is because you are going to or from a grid and one wouldn't use a 2E program for as the client side of a SOA would you?) (Though as I write I am thinking that I might have a need to populate a selection screen/pick list via a web service - if you don't know the reference number that needs to be validated it might be useful to allow the user to choose the one.) You could always get the user program to write the database records to drive the selection program but it would be nicer to do that within 2e (or to use one of Lee's selections based on a driver file)

These programs seem to work well and perform OK. (I haven't needed to stress test them yet (It might be more of a problem at the server end anyway)) Each program is customised in relation to which parameters it accepts, which web service it consumes, and how it parses the return data to find the parameters I'm interested in. It's not that obvious how 2E could help here - particularly as we need the program to be able to call the web service at different locations as we move from test to production.

cheers Harry

RE: Direct to web?

2012-05-16T19:42:25+00:00

Hi Crispin

No I haven't tried rexec. I have a java script on a windows server that takes the parameters from the pccmd and submits a web form with hidden parms.... Nice idea in theory, but I still see the password in my browser URL briefly before the webform submits. I guess I could try base64 encoding it on the i, then decoding it in the script, but it feels like a lot of hacking on the tree to get an apple to fall

RE: Direct to web?

2012-05-16T19:10:21+00:00

David,

Are you doing this internally?

We used rexecd on client machines and used the rexec() API on the i to do remote calls. rexec() does not have the 132 character limitation that STRPCCMD does, but requires the rexec daemon on the client to run. Eventually we dropped this because our network security would not allow outgoing remote calls (we run a service, so it would only work for us internally). rexecd allows you to define what ip address the incoming requests can come from, and some other nice things to stop bad things executing.

Crispin.

Direct to web?

2012-05-16T18:57:48+00:00

We have various business partners who provide us with access to applications via the web, where we hook into their apps using an http(s):// web request and a user id and password.

Wouldn't it be nice if 2E provided an interface to a URL (similar to a web form) with parameters that could be optionally hidden....so as to provide a seamless interface...or even better, (if I'm pushing my luck), a library of API's to call a variety of external (PC-based) functions (such as displaying a PDF, Excel spreadsheet, word doc, etc).

We're currently using STRPCCMD to call up a URL in a browser, (also to kickstart PDF's etc.) which is less than ideal for various reasons, one being the string size limitation. The size limitation can be worked around, such as by creating a batch file on the fly, but it's frought with peril and not pretty. Does anyone else have a similar need , or found a solution that works for them?

RE: Best practice to initialize array for Synon COBOL?

2012-05-16T16:58:36+00:00

Henky,

Personally I think the 2E implementation should not differ so drastically across generators/array size from a performance perspective. If the array is going over the 32K (or whatever) threshold that causes it to generate different code, then perhaps a better set of different code would be to generate the code equivalent of a RTVOBJ/DLTOBJ, instead of the user having to read the intricacies of the manual. This is such an esoteric difference, and really shouldn't be there. Maybe just do the equivalent of RTVOBJ/DLTOBJ all the time, regardless of array size. Machines are so much quicker nowadays why would it matter? This is just my opinion though.

If I were you I would open a ticket with CA, and see what they think...

RE: Consuming a web service in 2E

2012-05-16T16:45:00+00:00

Hi Simon,

Ggreat question!

So far, I have only consumed a Web Service that was created from 2E. A snake eating it's tail kind of situation. At the time I wanted to a) make sure that the Web Service created from 2E was callable outside of the IWS test harness and b) go through the process of consuming a web service.

At the time I used the wsdl2c process that creates the stubs. It was extremely complicated and took a lot to get it working (i.e. a technical challenge), but was fun to do. I think there is now a wsdl2rpg script that will provide RPG stubs. I have yet to investigate.

For the main part I see us providing web services for outside consumption, but I can see situations where being able to consume a Web Service that one of our Customers has published may well become something that we want to do. Not today, but maybe in the future.

If 2E was able to automate the wsdl2rpg (I suggest this only because I would think it was easier than creating the c or java stubs - but perhaps you could draw on your experience with the EJB java processing) stub creation, and somehow create a function that provided calls to the stubs, I can see that removing a lot of the black art involved in consuming a web service (we, all of it really). I have to wonder if a lot of the EJB processing would somehow fit this. Maybe/maybe not. I expect you have already considered this though

Consuming a web service in 2E

2012-05-16T15:23:24+00:00

Hey everyone,

I'd love to hear peoples' experiences of trying to consume a web service into 2E.

2E does not provide such 'consume' functionality automatically. (Of course r8.5 and r8.6 do allow us to deploy/publish/expose 2E business logic as a web service).

Has anyone had a need to 'consume' a web service into their 2E app? What was the business justification?

What success did you have?

What changes would you like to see in 2E to help this situation?

RE: Plex WebSydian Message Log

2012-05-16T08:35:43+00:00

Hello Derick,

I remember an issue one of our customers had who worked with Websydian/WSYDOM and who got the same message.
We were told by Websydian to have him check whether the function TerminateDom has been called for each Initdom call because not calling TerminateDom for each InitDom would cause this message to be sent due to resources not being freed.

Because as Websydian state in the online help. “A call to the TerminateDom function will release memory allocated by objects in the Websydian DOM and unloads the parser.” And this does not seem to be the case in your case.

On the Websydian Online help, I have found the following entry for your excecption code 4101:

4101 InitializationError Unable to initialize the COM library or the initialization function (DomServices.InitializeDom) has been called too many times without any calls to the DomServices.TerminateDom function.

Just enter 4101 in the search tab of Websydian online help to find a list of error codes and further hypertext links.

Perhaps these hints can help you solve the problem or at least narrow it down.

Numeric values as constants

2012-05-16T08:43:06+00:00

Give us the option to use numeric values as constants without the requirement to define a value for each number.

So we can get rid of things like:

while x <= (value.100 + value.100 + value.50) if we need to have a while <= 250.

Best practice to initialize array for Synon COBOL?

2012-05-15T22:09:43+00:00

So a common practice to initialize array in 2E is to have a keyless DLTOBJ over the array. This is also what's stated on 2E Building Applications manual: "A DLTOBJ with no parameters clears an array." (underneath "Array Processing").

Another method is to have a keyless RTVOBJ with a full-key DLTOBJ embedded.

I came across this awesome discussion about array initialization issue in Synon COBOL in the old Edge Forum . But I never experienced it firsthand until yesterday. So I used the common technique, the keyless DLTOBJ. I realized the generated codes get generated differently by 2E based on the array size.

For smaller array, the generated codes looks like this:

1* Initialize return code
2    MOVE SPACES TO W0RTN
3* Initialize array variables
4    MOVE HIGH-VALUES TO Y-YK02
5* Initialize last used element number
6    MOVE 0 TO YL02

For bigger array (according to the Edge discussions, if the array size is bigger than 32K), looks like this:

1* Initialize return code
2    MOVE SPACES TO W0RTN
3* Initialize array variables
4    INITIALIZE Y-YK04 REPLACING
5       NUMERIC BY 999999999999999999
6       ALPHANUMERIC BY HIGH-VALUES
7* Initialize last used element number
8    MOVE 0 TO YL04

Now on the bigger array version of initialization, the init of numeric fields with 18 digit numeric nines caused countless size exception errors on numeric fields with smaller size in the array layout. This caused very noticeable performance degradation. The error doesn't appear on joblog, but will be shown and noticed during debug.

Now notice that the discussion in the Edge forum was dated back in 2002. Before I experienced this issue firsthand, I was thinking, well now is 2012, maybe 10 years is long enough to have the issue fixed...

To get around the issue, I used the RTVOBJ/DLTOBJ approach. This seems to work fine. But I'm wondering if there's any better way of doing this, preferably not by EXCUSRSRC...

Thanks.

Hi Simon,

I think this gets overlooked quite a lot. Can you make this thread "Sticky" so it is always at the top of the 2E Forum?

Hi Mary,

Very interesting development. I can certainly see how this may encourage "readers" to participate.

There are still a few glitches, but they are being reported over in the MyCA Feedback Community. Anyone comes across something that doesn't see to work I encourage you post about it over here.

dragging to watch window InVariable.getVariable(m_strVarCE8teF_Input).getAsObCharFldField(m_strVarS5trhs2) ...

+ InVariable.getVariable(m_strVarCE8teF_Input).getAsObCharFldField(m_strVarS5trhs2) {AbCd} ObRun.ObRTTypes.ObCharFld

is displayed thwe exact value {AbCd}!
