Python is 31 today ; let’s celebrate it 🎂 

And special thanks to Guido van Rossum 

Context: 

mirrored configuration with one primary member and one async member (without failover/backup member)

Purpose:

replace the CACHE.DAT of a mirrored database on the primary member.

to dismount/mount a database, use Dismount() and Mount() methods in SYS.Database class available in %SYS namespace.
NB: the database ID is its Directory

You'll find  some examples of how to dismount/mount and check if a database is mounted (Mounted=1) or not (Mounted=0), and quickly see all the attributes of a database (via zwrite)

%SYS>set db="/opt/irisapp/data" 

%SYS>w ##class(SYS.Database).%OpenId(db).Mounted                     
1
%SYS>w ##class(SYS.Database).%OpenId(db).Dismount()
1
%SYS>w ##class(SYS.Database).%OpenId(db).Mounted   
0
%SYS>w ##class(SYS.Database).%OpenId(db).

This sample class will add parameter DSINTERVAL to each class containing the parameter DSTIME

To execute it from a Terminal :

SAMPLES>d ##class(adm.param).add(,,1)
[SAMPLES] parameter DSINTERVAL=5 added to class DeepSee.Study.CityRainfall (via adm.param)
[SAMPLES] parameter DSINTERVAL=5 added to class HoleFoods.Transaction (via adm.param)
[SAMPLES] parameter DSINTERVAL=5 added to class News.DeepSee.NewsArticle (via adm.param)
DSINTERVAL parameter was added to 3 classes

Class adm.

C:\data\backup.bat :

C:\InterSystems\Ensemble\bin\cache -s"C:\InterSystems\Ensemble\Mgr" -U%%SYS ##Class(Backup.General).ExternalFreeze() <C:\data\login.scr 

echo %ERRORLEVEL%

rem note that we need to check errorlevel from highest to lowest here.

A customer needs to add lines in the Excel sheet before the MDX resultset content.

Is there a more elegant/convenient way than modifying %DeepSee.UI.MDXExcel methods ?

Thanks in advance.

I’m interested in our DeepSee references who define cubes with external databases.
