Our back-up is taking 3-4 Gb per day... Why and how to solve it?

Hello gentlemen,

I hope you can help me because this is a very serious that I can't wait to resolve... Our back-up is currently taking 3 up to 4 Gb per day and we don't know why. We had 270 Gb yesterday and we are today at 274.3 Gb. We keep a computer history of the messages for only 50 days. Here is a picture of what's currently taking the most data place in our healtshare system:

(don't forget that our DB is also connected to the back-up, maybe it is related, I don't know)

Thanks you in advance,

Thomas

Looking for Example of How to Use %SQL.Export.Mgr Export Method

https://docs.intersystems.com/irislatest/csp/documatic/%25CSP.Documatic....

 

method Export(savertn As %Boolean = 0) [ Language = objectscript ]

 

I am looking to export table to a text file in a programmatic way. I am not familiar with this class and how to invoke a "savertn" as input here.

 

Essentially I would like to Export Table (SELECT * FROM Table) and save it as a text file locally on Linux server. Is there any examples out there of that? Perhaps I need to save the query output to a global and then pass that input to the export?

 

Thanks,

James

SQL - use specific index

Hello Community,

we want to use a specific index on our sql-class.

The index we want to use is called "iFilter".
Currently we use the following technique of ignoring all other indices because the automatically chosen index is always too slow. 

SELECT TOP 100 d0.ID FROM %IGNOREINDEX Belegindex %IGNOREINDEX KundenNrGlobalindex %IGNOREINDEX Rechnungsnummerindex %IGNOREINDEX Erfassungsartindex %IGNOREINDEX Belegsuche %IGNOREINDEX DatumAuftragindex %IGNOREINDEX OnlineBestellnummerindex %IGNOREINDEX Belegnummerindex %IGNOREINDEX KundenNrGlobalindex %IGNOREINDEX VAMindex %IGNOREINDEX BelegnummerbeiLagerLagerBestellungIndex %IGNOREINDEX iStatusSolr db.BelegeKopf AS d0 WHERE (((d0.KundenNr = 'BUKR01')) AND d0.ErfassungsartBez IN ('AB', 'AN') AND d0.DatumAuftrag >= '2020')

Do you know of a better/shorter way to resolve this?

 

Best regards.

Florian Hansmann

怎么获取Caché的CDC数据?

1.Caché数据库有没有办法配置然后用sql读取数据库实时变化的数据,类似于mssql那样?我看了可以写类去读取global获取journal的值,但是怎么用sql读呢?

2.不行的话,那用什么方式可以读取到journal日志文件,并输出日志文件的内容?

先谢谢大家了!!!
