Our team is reworking an application to use REST services that use the same database as our current ZEN application. One of the new REST endpoints uses a query that ran very slowly when first implemented. After some analysis, we found that an index on one of the fields in the table greatly improved performance (a query that took 35 seconds was now taking a fraction of a second).

Here is a simple way to reproduce the issue: 
2 classes: Utility.contacttypes and Utility.person
*************************

Class Utility.contacttypes Extends %Persistent
{
Property description As %Library.String(TRUNCATE = 1);
/// Index for property description
Index descriptionIndex On description [ Unique ];
}

Hi,

I am wondering if there is a way I can change the GUID of an instance. The use case is that I am restoring from a backup on an alternate host and start the instance there. However, the restored instance ends up with same GUID as that of source. Is there a way I can tell this newly restored instance to use a different GUID?

Thanks,

Raghu

We are creating a package (written in Caché Object Script) that will provide access to an external DB (MySQL). Because applications that use our package will be run from machines with various, potentially unexpected, operating systems, we’d like to establish a connection to the external DB without using DSNs (we’ve heard that setting up DSNs on certain non-Windows machines can be cumbersome and problematic).
