Question Jules Monoury · Jan 27, 2017

Hello community,
 

I'm triing to use perl with Caché on CentOS 7.

  • Caché is installed and working
  • Reading doc for perl module
  • Adding path of Caché/bin in PATH and LD_LIBRARY_PATH as suggested in doc
  • Creating mMakefile (perl Makefile.PL)
  • Success at compilation (make)
  • Fail at test (make test). And return the following message:

Can't load 'blib/arch/auto/Intersys/PERLBIND/PERLBIND.so' for module Intersys::PERLBIND: libcbind.so: cannot open shared object file: No such file or directory at /usr/lib64/perl5/DynaLoader.pm line 190.
 at test.pl line 10.

Question Mack Altman · Jan 21, 2017

Can someone direct me to where in the documentation we can find how consumption may be calculated for global storage?

Caché Version 2010.1
Operating System HP OpenVMS 8.4

EDIT: After receiving some responses, it seems I was unclear in my initial inquiry. I am looking to determine our rate of consumption of storage; however, I am having some difficulty in doing that.

While utilizing ^%GSIZE, which is used by the %GlobalEdit class, the results appeared odd. I have provided my results below, which illustrate the global structure on the left and the usage indicated by ^%GSIZE on the right.

Recently I started working with GitLab - GitHub self-hosted foss alternative. So far so good, liked the UI,  ease of administration, and available functionality (I was on Phabricator previously,  and still use it for repo mirroring).

GitLab has GitLab CI  (GitLab Continuous Integration) which looks promising (pluggable docker/vm/ds to run code) , but I wondered if someone uses it already and can share scripts for it?

Ansible helped me solve the problem of quickly deploying Caché and application components for Data Platforms benchmarks. You can use the same tools and methodology for standing up your test labs, training systems, development or other environments. If you deploy applications at customer sites you could automate much of the deployment and ensure that system, Caché and your application are configured to your applications best practice standards.

Hi, Community!

We have our internal backup system which produces *.cbk files for Full, Incremental and Cumulative backup modes.

Does anyone have an automation procedure to restore this files on some target testing system, check the integrity and mark the files as "restorable"?

Please, share?

Thank you in advance!

Last week I was onsite with a new customer of ours, implementing Deltanji to give them control of their development and deployment cycle. One particularly satisfying part of the visit was seeing their pleasure at how their production class now records its changes over time, allowing them to quickly diff the versions and see what configuration items have been added or what settings altered. ​

I have a server with public web application with Unauthenticated access and there seems to  be a problem that CSP session ends, but associated license persists for some time (hours). If several users log in, we can hit license limit and all the other users get 503 Service unavailable error.

We are currently debugging it and moving to authenticated web applications,  but is there a way to free these licenses quickly?

Here's how it looks like in SMP:

One of the great availability and scaling features of Caché is Enterprise Cache Protocol (ECP). With consideration during application development distributed processing using ECP allows a scale out architecture for Caché applications. Application processing can scale to very high rates from a single application server to the processing power of up to 255 application servers with no application changes.

Question Manoj Jayaraj · Dec 5, 2016

Hello folks,

      We have recently upgraded the cache (5.x) to cache 2016. All are working perfectly. But i am struggling in Telnet.

Working Good,

      when i connect to telnet it automatically gets the username(for example when we give the system ip addr(148.168.2.50), the ip address is taken as username) and directly goto the Password field in Telnet on old cache (5.x).

Now my problem is,

      I can't get the same from my new upgrade instance 2016. When i connect to telnet  it directly goes to username field but not to password field.

What is the problem ?

Enterprises need to grow and manage their global computing infrastructures rapidly and efficiently while simultaneously optimizing and managing capital costs and expenses. Amazon Web Services (AWS) and Elastic Compute Cloud (EC2) computing and storage services meet the needs of the most demanding Caché based application by providing
 a highly robust global computing infrastructure.

Hi -

I know that when specifying Caché password rules (i.e. what constitutes a valid password definition) that the "Pattern Matching" logic is what is getting leveraged under the covers to enforce the "A Password Must conform to X" rule. I was hoping that people could share some more sophisticated pattern matching rules. (in particular, I was wondering what a rule that would require non-repeating mixture of letter, numbers, & punctuation of an overall minimal size)

Question Dmitry Maslennikov · Nov 24, 2016

Just curious how many companies use in their work Docker containers, I mean not only with InterSystems products. And if such companies exist, which of them uses docker and doesn't  use it for InterSystems products  by some reasons. What are the reasons? For companies which already uses InterSystems in containers, how do you use it? Development environment, testing or even in production ?

And if you don't use but thought about it, what are the reasons which stop you.

As for me, I've been using InterSystems Caché inside a Docker container in some different cases:

This is a list of all the posts in the Data Platforms’ capacity planning and performance series in order. Also a general list of my other posts. I will update as new posts in the series are added.


You will notice that I wrote some posts before IRIS was released and refer to Caché. I will revisit the posts over time, but in the meantime, Generally, the advice for configuration is the same for Caché and IRIS. Some command names may have changed; the most obvious example is that anywhere you see the ^pButtons command, you can replace it with ^SystemPerformance.


While some posts are updated to preserve links, others will be marked as strikethrough to indicate that the post is legacy. Generally, I will say, "See: some other post" if it is appropriate.


Capacity Planning and Performance Series

Generally, posts build on previous ones, but you can also just dive into subjects that look interesting.

Question sansa stark · Nov 10, 2016

Hi All,

We are accessing the InterSystems`s cache database via UNIX ODBC and displaying the data in PHP website . Recently we have upgraded the PHP version to 5.6.  We are getting the nondisplayable characters (�) for only strings. But the numbers and date fields are displaying correctly. 

While querying the database via ISQL everything working fine (No Special characters).

I have looked around the internet and found the PHP 5.6 changed the default character to UTF-8.

For this issue anything, we can do from cache side.

This is the first article in a series discussing how to regain disk space from Caché databases at the operating system level. This introductory article discusses Caché database growth and gives an overview of various methods you can use to return unused disk space that is allocated to database files back to the file system. But before we talk about returning space to the file system, let’s first review how does it get allocated in the first place.

Starting with the Field Test of 2017.1 InterSystems products will include Feature Tracker. It is enabled by default during the Field Test and is explained more fully in the product documentation included below. Information collected by Feature Tracker is limited to technology usage information and instance identification.  This tool has been carefully crafted to not transmit sensitive information related to customer applications or data. It is important to note that sharing of information about your system is under your control and the information being shared with InterSystems is always

Hello

I have noticed that Cache (2016.1 at the time of writing) doesn't come with a systemd startup script for RHEL7.

Here is a small example script I have built.

[Unit]
Description=Intersystems Cache

[Service]
Type=forking
ExecStart=/bin/bash -c '/usr/cachesys/cstart 2>&1 | logger -t cache_start'
ExecStop=/bin/bash -c '/usr/cachesys/cstop quietly 2>&1 | logger -t cache_stop'
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

The file should be placed as /usr/lib/systemd/system/cache.service

After saving the file, use these commands to install and run the Cache service
