Hi Manikandan,

Objectstar does have a good scope and it supports well as an ESB(Enterprise Service Bus) in the middleware. Since it is new technology, the resource and the materials are in less. Definitely it has a good opening and in near future there will be more requirement.

Hi,

ObjectStar is a programming environment, originated in the '90's. By then it was a revolutionary (object-oriented) way of application-development. The only drawbacks were that it was 'under construction' for a long time which left a lot of open ends and a limited development environment that made maintenance a menace.

In 2006 (I believe) it was purchased by TIBCO and made a part of the TIBCO suite of products that implement (as mentioned in other replies) an Enterprise Service Bus. Mainly used to disclose almost any datasource on the mainframe to that bus. In this context O* is at its best!

As an application-development-tool it is surpassed by 'better' languages and environments, with which it has a lot in common. In the 'middleware'-layer it is an excellent language with a lot of promesses for opening up the legacy-world.

Hi,
Handling exception on rules & tables could be done on specific exception operation if identified.
In general most of the known exception arise due to table operation like, GETFAIL,INSERTFAIL,REPLACEFAIL & DELETEFAIL. This could be handled by coding in exception part like
ON GETFAIL:
CALL MSGLOG('GETFAIL ON TABLE': xxxxx) (code how you want to handle this exception). Like that you can go for handling individual exception raised.

In case if not specific to the exception type(need to handle all type of exception), Just have a generic like
ON ERROR:
Handel how you want.

Thnx
Vishwa.

Manikandan, Vishwa,

The O* rule-editor is devided into 3 parts: the condition-part, the action-part and the exception-part.

signalling of exceptions can take place in the action-part of a rule (and as actions after handling of a specific exception).

You should also be aware of the following:
+ exceptions should be handled within the 'call-tree' of rules (you cannot 'jump' to a new rule or transaction-levels). This is espessially important when you use transaction-level breaks.
+ you should be very carefull with ON ERROR, since it will catch ALL errors (even the ones you would not like catching). This can cause endless loops!
+ you can use exceptions as loop-delimiters (UNTIL <exception>; end;).
+ there are a number of system-generated exceptions. they follow a certain hierarchy (please read the reference-manual). This should also be taken into account when programming exceptions.

Hi Mani,

The function VALID_NAME will answer your question.

Thnx

Mani,

In O* Call & Transfercall is more over similar.

Call:
1.Invokes the rule with the scope of current transaction.
2.Call doesn't have a mode of operation.

Transfercall:
1.Terminates the current transaction & starts a new one.
2.Can have a mode of operation. Eg
TRANSFERCALL IN BROWSE .....
TRANSFERCALL IN UPDATE .....

Thnx
Vishwa
