Hello,

 

I try to open an existing log file and append to it. In Windows I use Open file:(NRW):1. I would expect it to append to the file, but each time I execute the code I get only the new entries, the prior file content is lost.

 

What is the proper syntax top open a file in "Append" mode?

 

I will deploy this code in Linux. Is there a different syntax to open a file in Linux versus Windows?

 

Thanks,

 

Oliver Wilms

Starting with 2017.1, InterSystems is adding Ubuntu (64-bit) as a third linux server platform. Prior to 2017.1 Ubuntu was already available as a development platform and customers could use InterSystems distributions build for SUSE to run on Ubuntu. As a result there are a few license key implications for 64-bit linux versions starting with Caché and Ensemble 2017.1:

a) Customers using RedHat will observe no changes

b) Customers using InterSystems products(1) for SUSE on SUSE will need new license keys (no charge)

InterSystems is currently verifying InterSystems IRIS 2019.1 with Windows Server 2019. This work is scheduled to complete by the end of January  2019. In the second half of this month InterSystems will add Caché/Ensemble 2018.1.2 to be verified on this platform.

As we get closer to the completion of those tasks, I will update this post with information on release dates, and which products and version will support Windows Server 2019.

The Amazon Web Services (AWS) Cloud provides a broad set of infrastructure services, such as compute resources, storage options, and networking that are delivered as a utility: on-demand, available in seconds, with pay-as-you-go pricing. New services can be provisioned quickly, without upfront capital expense. This allows enterprises, start-ups, small and medium-sized businesses, and customers in the public sector to access the building blocks they need to respond quickly to changing business requirements.

InterSystems has completed the verification process for OpenJDK 8.

Customers now have the option to either use the Oracle JDK, or the OpenJDK with all InterSystems products and versions that support Java 8.
 
Support for future versions will continue to be supported on both of these Java Development Kits.

Google Cloud Platform (GCP) provides a feature rich environment for Infrastructure-as-a-Service (IaaS) as a cloud offering fully capable of supporting all of InterSystems products including the latest InterSystems IRIS Data Platform. Care must be taken, as with any platform or deployment model, to ensure all aspects of an environment are considered such as performance, availability, operations, and management procedures.  Specifics of each of those areas will be covered in this article.

Starting with 2017.1, InterSystems has moved macOS from being a server platform to a development platform. 2017.1 will only support macOS 10.12 and will no longer be available as dmg kits.

Verification of macOS 10.12 has not been completed at this time and Field Test kits for this platform are not yet available.

What are the best steps for troubleshooting printing to a Windows printer from Cache.  The printer has been configured in the Windows Printer Manager and has been able to print a test page (from the windows print manager).

The device has been configured in Cache -> Sys Admin -> Config -> Device Settings -> Devices with properly formatted |PRN|printer device name and "W" for open parameters and 101 for Alias.
