Dynamic Global Cleanup/Orphaned Globals

Was wondering if anyone had a Dynamic way to see if a Global is still being used by a Class File. 

We have been monitoring our Global Size recently, and I am trying to find problematic Class files that are not being cleaned up or used appropriately. I have come across some globals that do not seem to have a Class attached to them anymore, and instead of deleting globals 1 by 1, I was looking for a way that we could dynamically do this since the globals have data that is stale in them.

Thanks

Scott

How can I manage globals directly from a remote Java application in Cache (2016.1.1) without relying on cacheextreme.jar or requiring the application and Cache Server to run on the same machine?

I’m trying to find a way to manage globals from our Java application. We have two separate features:

  • Managing tables normally using SQL

  • Managing globals, since some globals exist without class or table definitions

Cache version : Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2016.1.1 (Build 108U_SU), Thu Jul 7 2016 09:39:04 EDT

I tried to retrieve the globals tree, update node values, and append nodes using SQL by calling stored procedures, but I couldn’t find any procedures for adding, updating, or deleting nodes.

I also tried using cacheextreme.jar to access the globals API directly.

Can globals exist without SQL access?

Hello everyone,

My team lead mentioned that users can sometimes create globals directly without associating them with tables or classes. In this case, these globals would not be accessible via SQL.

Is this correct? Can a global exist independently in this way, and if so, is there a specific approach to access or manage them without SQL?

Web interface for maintaining custom lookup classes (SQL) in HealthShare

Hi Team, 

Can I please check if anyone has built a simple web interface for maintaining custom SQL lookup class.  

We have a simple persistent class in HealthShare which is used for storing Pathology test codes. Test codes in this lookup class is used for message filtering and applying additional logic when processing pathology results/orders. 

We want to make this class available to external users from pathology (not the usual management portal users) to maintain so that they can add/edit/delete test codes as required.

$Name from a parameter

Hi IRIS experts!

I have a parameter in a class that stores a global name:

Parameter GlobalName = "^AGlobal";

then I'm trying to call it as:

set gn=$name(..#GlobalName)

to use it later as:

set @gn@("index")="value"

But! I'm having syntax at set gn=$name(..#GlobalName)

What am I doing wrong?
