Caché Upgrade Checklists - InterSystems Documentation

Caché 2012.1 Upgrade ChecklistUpon upgrade, the installer will examine the value set for the gmheap:• If the value set for the gmheap < 21184KB, it will increase the gmheap to that value.• If the value is > 21184KB, the installer will leave the setting untouched. In this case, administrators are assumed tohave other reasons for setting the gmheap value higher, and this new memory demand should also be taken into accountin their calculations of a new value.Also in this case, if the value does not permit the loading of the basic language tables, Caché will produce a warningin cconsole.log and attempt to degrade gracefully.If applications wish to take advantage of languages other than English and Spanish, the gmheap size must be furtherincreased per language desired. The following table gives the available language model and the amount of the increase.For those, with gmheap sizes above 21184KB, the sizes of English and Spanish tables are also included.Language CodedeenesfrnlLanguage NameGermanEnglishSpanishFrenchDutchMemory Needed4.5 MB3.3 MB12 MB4.4 MB3.6 MBFinally, if a site does not intend to use any of the iKnow capabilities, the gmheap value may be set lower after the upgrade/ installation. This will require a restart of Caché to take effect.2.1.3.2 Emergency Mode Runs Under the Owner Userid, Not As RootThe emergency mode startup code is now run under the owner userid, not “cacheusr”. This prevents unnecessary failuresin attempting to initialize certain resources, such as the CSP portal.2.1.3.3 Defragmenting Globals Now Requires %Admin_ManageDefragmenting the globals in a database now requires the %Admin_Manage role. Previously only write access to thedatabase was required.2.1.3.4 ^DATABASE Functions Extended To Non-Primary Mirror MembersBeginning with this release, the various ^DATABASE functions related to returning free space, compaction, truncationand defragmentation can now be run on mirrored databases from all mirror members regardless of their current role. Previously,they could only be run on a node when it was the primary mirror member.2.1.3.5 ^DATABASE Menu ChangedThe ^DATABASE menu was changed in this version to add the option4)* Mirror Set Name:under the menu item1) Create a databaseSites which drive ^DATABASE via scripts should take note.8 Caché Upgrade Checklists
