Caché Upgrade Checklists - InterSystems Documentation

Caché 5.1 Upgrade Checklist11.1.23.11 Upgrade Only Processes Local DatabasesIn Caché 5.1, $SYSTEM.OBJ.UpgradeAll() only scans local for local databases to upgrade. It ignores remotely mounteddatabases. These must be upgraded by running UpgradeAll() on the remote systems.11.1.23.12 Caché Versions for ECPBecause of the upgrade to the compiler, systems in an ECP configuration must either be:• all on version 5.1, or• the data server must be on version 5.1 and the application servers can be either on version 5.0 or version 5.1.Note:It is possible to run version 5.1 application servers with version 5.0 data servers, but this requires that the routinesused by the application servers be mapped to databases local to the application servers. If you believe you haveneed to do this, please contact the InterSystems Worldwide Response Center (WRC) for assistance.11.1.23.13 Moving Applications from 5.1 to Earlier VersionsPorting an application from Caché 5.1 to an earlier release is problematic and depends on what features in this version theapplication depends on (compiler behavior, new streams implementation, changes in exported XML for applications, newclass representations — to name a few). If you believe you have need to do this, please contact the InterSystems WorldwideResponse Center (WRC) for assistance.11.1.23.14 ODBC and JDBC CompatibilityDue to a change in protocol, the ODBC and JDBC clients supplied with Caché 5.1 are compatible only with Caché serversfrom version 5.0.13 and later. Attempts to use connections to Caché servers in versions before 5.0.13 will result in errors.11.1.23.15 RoseLinkRoseLink currently attempts to access Caché using only the standard SQL username and password. Therefore, it will notbe supported on systems whose default installation security level is Normal or Locked Down. This restriction will be liftedin the next maintenance version of Caché 5.1.In addition, the user must have %Development:Use permission in order to access classes for its use.11.1.23.16 DreamweaverThe connection that Dreamweaver MX uses to access Caché is not available with this version. This restriction will be liftedin a future maintenance release of Caché 5.1.11.1.23.17 Perl and Python Language BindingsThe Perl and Python language bindings are supported only on 32-bit versions of Windows.11.1.23.18 C++ Language BindingThe C++ language binding is supported only on the Windows platform using Visual Studio 7.1.11.1.24 Platform-Specific ItemsThis appendix holds items of interest to users of specific platforms.242 Caché Upgrade Checklists
