Hello to my fellow Cache Gurus:

I ran into two issues with Cache to XML Export and Cache to JSON Export in regard to array sequences. So before I waste time opening a WRC ticket, I figured I would poll the Development Community, since there is always so much wonderful feedback and suggestions via this Developer Community! So much thanks in advance for everyone's input! Go Team!

Hello,
In short, I am trying to get the Content-Length of my response,

We have a CSP application, when we get a new request we begin to process it, throughout the app we WRITE to the response in different places,
now when the response is about to be sent back to the client - we would like to know its Content-Length (in the RESPONSE HEADERS).
So it comes down to two questions:
1. How can we access the Content-Length of our response?

Hello,

One of our clients has a 'Notes' class with over 3 million records. We have a report that pulls data from this table that was taking about an hour to run. Our test environment (which has a copy of the production database) runs the same report query in 1 second.

We attempted to purge and rebuild indices which made an improvement (down to 15 minutes) but still not great.

I have a module that sends EMAIL from a Cache INT routine (listed below).

In order to make sure the columns align in the body of the message that the recipient receives I want to force the setting of the FONT and SIZE in the body.

Does anyone know what I need to insert in this code in order to control font and size?

Alternatively is there a way to send mail from within Cache that will keep column data aligned?

Thanks.

I'm dealing with a situation that leaves in doubt what I understand about CACHE.WIJ (C:\Roche\CobasInfinity\HealthShare\mgr)..
Journal files store records already written to the base.. and CACHE.WIJ records not yet written to the base..
theoretically, the data contained in CACHE.WIJ is temporary... until the record is written to the base (consequently generating journal).

Good morning,

First of all we would like to thank you for your time reading, thinking and aswering this question.

We have been developing a Transformation to convert a source ORU_R01 to a target ORU_R01. For each OBX segment we need to check an if, and then, if it is true we just need to put this OBX and continue to the next iteration, otherwise, if it is false, we need to put (copy) the ORC + OBR + TQ1 before this OBX, and then put this OBX, and after that, the SPM.

As I was trying to create a routine search query via RoutineList, I discovered that documentation both for Cache and Iris offers only ABC* and ABC? syntax for including routine names and, unlike %RO, does not offer name ranges. Is that indeed so?

After some system files reading, I discovered that you can EXCLUDE certain routines with ', by using the 'ABC or 'ABC* syntax. That is not documented but it should be. Any other non-documented RoutineList syntax capabilities?

New to Python. Attempting to use pypyodbc to select data from a table in one Cache database, and inserting into a similarly configured table in another. Process works fine except for tables containing Date types. NULL values in date columns are handled without issue, but when data is present, insert fails with:

An error occurred: argument 7: TypeError: 'NoneType' object cannot be interpreted as an integer.
