Caché Upgrade Checklists - InterSystems Documentation

Caché 2007.1 Upgrade Checklist9.1.8.3 Remote Database PathnamesIn prior versions, upgrading would change the drive letter for remote databases to uppercase. This is no longer done. Thosesites with Windows ECP servers should examine the pathnames for remote databases in [Home] > [Configuration] > [RemoteDatabases]. Those whose drive letter is in uppercase should be changed to lowercase.9.1.8.4 UNIX® / Linux / Mac OS X• Daemon PrivilegesIn versions of Caché prior to 5.1, daemons always ran as root, and Caché used that privilege to set the UNIX®parameter RLIMIT_FSIZE to unlimited. However, since 5.1, the Caché daemons may run under a different userid.Since only root may set its own limits, the limits cannot be set for a non-root owner.In addition, when running as a non-root user, Caché failed to set the current (soft) limit to the hard limit. In this case,even if the RLIMIT_FSIZE hard limit was unlimited, if Caché was started from a login user whose soft limit was setto some lower value, the Caché daemons ran with this lower value, and could encounter serious I/O errors attemptingto write to CACHE.DAT or CACHE.WIJ.Cache now checks that the RLIMIT_FSIZE hard limit is unlimited, and halts the cache startup (or installation) withan error message if this is not the case. Second, it sets the soft limit to the hard limit in the daemons.• CDL Support Dropped for Mac OS XIn this version of Caché, CDL support has been removed from the Mac platform. Please use XML for transport ofapplications across platforms.9.1.8.5 Feature: xDBCClient applications attempting to connect to server systems running this version of Caché must be running on Caché version5.0.13 or later. Attempts to connect from earlier versions will fail.Please contact the InterSystems Worldwide Response Center (WRC) if this is an issue for your site.9.1.8.6 Dreamweaver No Longer SupportedThe release of Caché no longer supports any version of Dreamweaver as a method for generating CSP pages.9.1.8.7 Python Binding Version RequirementsFor Caché version 2007.1 on Windows, customers wishing to use the Python language binding should use ActiveStatePython 2.4 with Microsoft Visual Studio 7.
