The DeepSee Shell best Practices Series - Execute an MDX query in the DeepSee Shell with/without results cache

This cache is different from cache reset. Cache reset clears everything in the namespace but “cache off” only clears the cache in ^DeepSee.Cache.Results and ^DeepSee.Cache.Axis global node for the corresponding cube. The difference is quite smaller in the case as below, but in some cases it can be a big difference.

Presenter: Murray Oldfield
Task: Avoid bottlenecks caused by scaling up, before they become a problem
Approach: Discuss what operating system and InterSystems metrics you should look at and how to interpret them

Systems behave differently when database activity scales up. In the worst case, bottlenecks appear and users are impacted. This session shows you which operating system and InterSystems metrics you should be looking at and how to interpret them so you can head off bottlenecks before they impact users. This sessions also shows strategies for planning infrastructure taking into consideration InterSystems' data platforms requirements.

NewBie's Corner Session 4 The Plus Sign and Concatenation Operators

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Plus Sign (+) operator

Typically, the Plus sign (+) adds two numbers together. This is true in COS (Caché ObjectScript), but COS uses it in other ways as well.

Set the variable X to a value of +12

2015.2.4 Maintenance Release

Developer Community email notification subscriptions

Serenji 2.6 is now available

1. Don’t use Python built into Mac. Because of System Integrity Protection (SIP) you will not be able to access the libraries that the InterSystems Python binding requires. The Python build into the MAC has baked in what libraries it can use.
2. Install another Python. Don’t put this other ahead of Mac Python on path since this could break things. Apple regards its Python as part of the its OS, and may use that Python in its system operations.
3. This Python will not be installed into the protected area.

I have posted to aid others in diagnosing problem with SSL/TLS connections to superserver port from .NET client executable.

The cache instance this appeared on is quite old - 2011 - so I do not know if Intersystems have added a better error message in a later version

The actual fault was due to the certificate in the %SuperServer SSL/TLS configuration having expired.

The unhelpful message that appeared in the .NET client included the following partial stack trace.

We heard from a customer who wanted to display a version number as a read-only production setting. During the build on the build server, this version number is added to the Production class. This works fine, and the Version is displayed in the Portal, but the customer wanted to write protect it, so the enduser can’t change it. The customer had defined the setting like this:

Property Version As %String;
Parameter SETTINGS = "Version:Info";

We advised the customer to define SETTINGS like this instead:

Parameter SETTINGS = "Version:Alerting:label"

I am pleased to announce the next 2016.2 field test kit, 2016.2.0.605.0.

There are about a hundred changes from the previous field test kit, including the following fixes to problems found by those using the kits in the field:

Hi, Community!

The Second Global Summit Free Registration Contest is running and we have only one week to celebrate new winner!

Presenter: Mark Bolinsky
Task: Decide whether a converged infrastructure is ideal for your enterprise applications
Approach: Discuss best practices and provide guidance on the right questions to ask

The traditional use of “SAN storage” is no longer the only choice for deploying enterprise application. Software defined data centers are making inroads into enterprise data centers, and there is good reason for it. There is the potential for significant infrastructure cost savings, architecture simplification, reduced administration costs, and depending on the configuration - even better performance. This session will discuss some best practices and outline decision guidance to help you ask the right questions when considering hyper-converged architectures.

Presenter: Maxim Vershinin
Task: Easily extend your solution’s range of interoperability
Approach: Build Java-only business services and business operations that exploit open-source Java libraries

Problem: The title states the problem Open source java libraries exist for hundreds of protocols and formats. This session explains how you can easily build java only Business Services and Business Operations to that exploit these libraries to extend the range of interoperability.

InterSystems is pleased to announce that Caché and Ensemble 2015.2.4 are now available as maintenance releases.

For a complete list of the corrections in 2015.2.4, please review the release notes.

Caché and Ensemble 2015.2.4 are available for the same platforms as 2015.2.3, with this exception:

It has been noticed that some customers running JAVA programs (for example, FOP) on AIX would see the server eventually running low then out of memory. Customer would notice the system pages heavily and user experience becomes bad. And the server would crash when out of memory.

When the problem happens, we can see in ipcs a lot of shared memory segment marked for deletion (Capital D at the beginning of MODE section). This means they will not disappear until the last process attached to the segment detaches it.
