Error handling refers to the response and recovery procedures from error conditions present in a software application. It is the process comprised of anticipation, detection and resolution of application errors, programming errors or communication errors.
If you familiar with ObjectScript you know what is it. I'd love to hear the history of the case why it had appeared in ObjectScript but it turned out that almost every system/library classmethods return %Status and there is a whole set of tools to deal with it.
What is does it gives you the responsibility to check the value or %Status of every system method you call.
E.g. if you save the data of the persistent class, you should never call like this:
do obj.%Save()
you need to call:
set sc=obj.%Save()
if $$$ISERR(sc) do // something or quit.
Standard error logs in IRIS / Caché / Ensemble are written global ^ERRORS. As this piece dates back some decades back to previous millennium its structure is far from the typical SQL storage structures.
I have a case where our EMR is sending data, but not all the values needed for the Ancillary are valued properly and causes that message to error/halt processing on the Ancillary system, not ideal but its what they do. I would expect them to still process the message except that 1 field, but they don't.
I want to add validation to make sure certain fields are valued correctly for the Vendor.
So I add some statements to take those items that don't pass this validation out to a batch file with headers.
If you're solving complex problems in ObjectScript, you probably have a lot of code that works with %Status values. If you have interacted with persistent classes from an object perspective (%Save, %OpenId, etc.), you have almost certainly seen them. A %Status provides a wrapper around a localizable error message in InterSystems' platforms. An OK status ($$$OK) is just equal to 1, whereas a bad status ($$$ERROR(errorcode,arguments...)) is represented as a 0 followed by a space followed by a $ListBuild list with structured information about the error. $System.Status (see class reference) provides several handy APIs for working with %Status values; the class reference is helpful and I won't bother duplicating it here. There have been a few other useful articles/questions on the topic as well (see links at the end). My focus in this article will be on a few debugging tricks techniques rather than coding best practices (again, if you're looking for those, see links at the end).
A unit of ObjectScript code (a ClassMethod, say) may produce a variety of unexpected side effects by interacting with parts of the system outside of its own scope and not properly cleaning up. As a non-exhaustive list, these include:
I'm trying to get started with IRIS for Health but every time I got to a step that asks me to install a .whl-package I cant continue. I'm getting an error that the file does not exist.
There does not seem to be any separation between the error code and error text in a %Status object. For custom errors, I simply want to display the message and not Error #5001: Some error text.
ObjectScript has at least three ways of handling errors (status codes, exceptions, SQLCODE, etc.). Most of the system code uses statuses but exceptions are easier to handle for a number of reasons. Working with legacy code you spend some time translating between the different techniques. I use these snippets a lot for reference. Hopefully they're useful to others as well.
I've overrided the HS.FHIRServer.Storage.BuiltInOperations class, and generally all works fine except of error handling. Where can I find a server setting option to ask IRIS to return OperationOutcome if an Internal Server Error occurs? Currently it returns non-informative HTML instead of JSON/OperationOutcome.
许可证检测中，当前许可证使用达到100%，我们应该如何迅速处理解决它？并且不影响生产环境。
In license detection, the current license usage reaches 100%. How can we deal with it quickly? And does not affect the production environment.
New to Health Connect so please forgive me if this is a stupid question! Is there a specific error code returned when a user initiates an abort from the jobs tab of the business host? I want to be able to treat the Abort as Completed due to our complex business process. Currently, hitting abort just retries the message to the same business operation. Want I want to do is provide the error code used by the Abort (if there is one) and treat it as OK
I have an XML I am sending to an operation from a BPL. This is a query for Patient information from Epic using a web service. I created the operation using the add-in in Studio. I setup the BPL to do a Call and send whatever data I receive from the client. I get a response back from Epic with a list of matching Patients. In the BPL I am trying to use the Response Builder to pass the response ID, name, DOB, etc. to matching context items to then pass to the client as a response. I get the following error within the call:
I used the operation : EnsLib.EMail.AlertOperation to send mail to handle error. However, I want to get more information about the error (session ID message, the date, the namespace... etc).
what is the best way to do it?
I tried to add informations in OnAlertRequest method as below but I need to change mail operation from all namespaces...
Can anyone help me about Global ^Errors? Only in 1 specific namespace is it growing fastly. It grows from 2 to 3 Gb per hour when all services are active. Which commands exactly do this? In another similar namespaces, there is not that Global in the class list.
We have a vendor that every couple of days will just stop transmitting messages, but still hold the TCP/IP connection open. No matter how many times we troubleshoot and talk with them, they don't seem to think its an issue with system. Normally if I just restart the service it will get the data flowing again.
Hi, we suddenly noticed that one of the edge storage increased by 30% and it was due to ERROR globals which was throwing repeated error for 7 days and it consumed 35GB space. Is there a way to log the storage of edge production on daily basis and compare the increase in storage with previous day and if increase is 5% more than trigger an email to system admit to look why the storage increased suddenly.
Alerts are messages generated by production components. InterSystems IRIS automatically writes the alerts to a log file and sends then to the production component named Ens.Alert. If your production does not have a component named Ens.Alert, then InterSystems IRIS writes alerts to the log file but does not send them to any component. The component named Ens.Alert can be of any class. The most frequently used classes for Ens.Alert are:
I want to grant access to view the Error Trap in System Management Portal to certain admins, without giving them access to anything that would alter Caché behavior, such as users or database sizes. I was looking for a granular Resource that would do this, but haven't been able to find what I'm looking for.
I need assistance to delete an instance of HealthShare that I am sure it way out of date. From the VM Server Control Panel when I try to Uninstall, I get the error Message: "Error: Could not detect INSTANCE name!"
Are there commands in SQL that may help uninstall the instance of the application? Other Suggestions?
The intersystems documentation gives the same description for both <MAXSTRING> and <NETWORK DATA UPDATE FAILED - MAXSTRING>. I suspect that the description for <MAXSTRING> is correct and the description for <NETWORK DATA UPDATE FAILED - MAXSTRING> was an accident. I would like to know what situation triggers the <NETWORK DATA UPDATE FAILED - MAXSTRING> error.
I have some code in a mac routine that use indentation and the "." character :
IF condition1 DO
.WRITE YCR,...
.WRITE YCR,...
.WRITE YCR,...
I would like to add a try / catch block between the write statements. I can't refactor the whole code and use indentation with curly braces instead (there is too much code, not written by me)
I have tried the following but it does not work (it compiles, but code stop running right before the try keyword)
Hey everyone as you may know I am a beginner and I am kindly asking for some assistance in a problem I have been solving. The problem is that I am calling a user defined function within a procedure called occupiedseatsAdj and the compiler comes up with this error.
