Advisory: Missing Globals with Mirror Database Download

30 Sep 2025

Summary

Advisory ID	Product & Versions Affected	Risk Category & Score	Explicit Requirements
DP-444543	InterSystems IRIS® data platform InterSystems IRIS® for Health HealthShare® Health Connect Versions 2025.1.0, 2025.1.1 and 2025.2	Operational: Medium Risk	Occurs only when using the Mirror Database Download feature with databases containing %SYS, %IRIS, %odd, %nls, %csp*, or other globals listed in the advisory.

Issue

In InterSystems IRIS, InterSystems IRIS for Health, and HealthShare Health Connect, versions 2025.1.1 and 2025.2.0, the new “ Mirror Database Download” functionality does not include certain globals. This is limited to the rare case when a mirrored database includes system global names that do not typically occur in mirrored databases. When using this feature, mirrored databases that contain the following globals will be incomplete:

%IRIS*
%ISC.*
%MV*
%SYS
%csp*
%iKnow
%nls*

%odd*
%sqlcq
%tercap
CacheTemp*
IRIS.* (except IRIS.Msg and IRIS.MsgNames)
ISC.* (except ISC.Src.Jrn)
mtemp*

Impact

This is a silent completeness issue: the mirrored database download appears successful but omits the above globals.

This issue affects versions 2025.1.0, 2025.1.1 and 2025.2.0 of the following products:

InterSystems IRIS
InterSystems IRIS for Health
HealthShare Health Connect

This issue only affects the new “ Mirror Database Download” feature. All existing mirroring features are fully operational and performing as expected. Using a manual restore to populate the mirror database (which was the default procedure prior to the release of this feature) is a simple workaround.

Resolution

This issue has been corrected in versions 2025.1.2 and 2025.3.0 of the products.

2025.1.2 is scheduled for availability on October 22, 2025.
2025.3.0 is scheduled for availability on November 19, 2025.
In the interim, customers who require the correction prior to these releases may request an ad hoc distribution for the fix (DP-444574) through the Worldwide Response Center.

If you need to populate a mirrored database containing any of the globals listed above, copy the globals from one mirror member to another either using traditional backup/restore strategies or by manually copying the IRIS.DAT database.
