Red Hat Enterprise Linux (RHEL) is a Linux distribution developed by Red Hat and targeted toward the commercial market. Red Hat Enterprise Linux is released in server versions for x86, x86-64, Itanium, PowerPC and IBM System z, and desktop versions for x86 and x86-64.
There are often questions surrounding the ideal Apache HTTPD Web Server configuration for HealthShare. The contents of this article will outline the initial recommended web server configuration for any HealthShare product.
As a starting point, Apache HTTPD version 2.4.x (64-bit) is recommended. Earlier versions such as 2.2.x are available, however version 2.2 is not recommended for performance and scalability of HealthShare.
This post provides useful links and an overview of best practice configuration for low latency storage IO by creating LVM Physical Extent (PE) stripes for database disks on InterSystems Data Platforms; InterSystems IRIS, Caché, and Ensemble.
I am looking for a way to deploy production changes (code and/or production configs) via script or some other systematic way other than the Ensemble/Deploy page in the Management Portal. My goal is to store these configurations in Subversion, then have a piece that can pull the XML from source control and deploy it to a given server. Is there some kind of script that I can run on a given server to perform this deployment? If so, I can tie it up with Subversion using another tool that I have access to.
I have been asked to assist in the planning of the a new server for our database, which we will be changing operating systems from OpenVMS to Linux (RedHat distribution). However, its difficult to find material regarding what would be recommended, which is likely due to the database being proprietary.
In looking at the information provided below and hoping to decrease processing time, would anyone be able to recommend type of configuration we should have for the new Linux server? Please feel free to ask any clarifying questions.
Have you ever thought what could be a reason why some development environment (database, language) would eventually become popular? What part of this popularity could be explain as language quality? What by new and idioms approaches introduced by early language adopters? What is due to healthy ecosystem collaboration? What is due to some marketing genius?
Too often users finding themselves in need of a software solution do not consider “open source” vs. “proprietary” alternative. Most of them either have their go-to favorite developer or just google for reviews and ready-made answers. However, this alternative must be the starting point of their search, as the decision has the most consequences.
It is not an overstatement to say that open source is the future of technology, albeit, it has its own unique challenges. Here is what users, especially corporate users should consider choosing the software for their business needs.
(We are in contact with IS support for this problem but I would like to ask Community too, perhaps somebody experienced this problem in the past)
Hello Community,
we need your help with Cache 2017.2 freezing on Linux machine.
Since we moved our primary production Cache from Windows to Linux in the begging of this year, we have experienced system freezing twice. Yesterday without any good reason Cache stopped to respond with the log shown below.
Currently, we are running 2014.1 on two different servers (OpenVMS, RHEL). The plan is to transition from OpenVMS to RHEL, but our Write Daemon is in a Troubled state on both servers.
On the OpenVMS server, we have a WIJ file that's 26G and can grow to 40G (size of database cache). Since it hasn't grown to 40G, we don't believe the size of the WIJ file to be the issue.
What else should we be looking at regarding the performance of the Write Daemon?
Is anyone using Veritas NetBackup 8.1 to backup Caché database? DB is on Linux 7.4 on host running VMware ESXI 6. Size of DB is about 1.5TB. Any advice on integrating with freeze/thaw.
I have a DR member and in this cache server the database "cachetemp" start to getting bigger without any reason (50GB that was all the free disk space we have)
In the members of the mirrors the cachetemp its ok and the size is 31MB.
I restarted the server because I read that the cachetemp database purge when restarting, but didnt happend.
Any recommendation to clean this database? can I just deleate the CACHE.DAT from this database?
We will be transitioning from a server running HP OpenVMS to one running RHEL 7. The main question some of the team had was what would be the best method for moving the globals to the new system.
Also, I was wondering if any others have transitioned from OpenVMS to RHEL. If so, were there any kinks that we should be aware of prior to transition?
Caché Version String: Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2016.2.1
We have a mirrored Ensemble system (110, backup and 210, primary). At one time (14:00) there is a disruption in the production. The messages are not being processed.
I am designing the software architecture for an Ensemble/Healthshare production to be deployed on Amazon AWS EC2 servers (2 mirrored m4.large - 4 vCPUs / 16 GiB RAM running RedHat Linux 3.10.0-327.el7.x86_64 and Healthshare for RHEL 64-bit 2016.2.1). It's a rather CPU-intensive production involving massive XSLT 2.0 transformations (massive both in terms of size and volume). I was wondering if anyone has experience configuring Ensemble productions on EC2 servers. My question or concern has to do with the following statement in the Ensemble documentation:
I'm trying to add a DR async member to a mirror but when I add this member I get this messages in the mirror monitor (on the DR member):
The message im talking about is the "missing Mirrored Databases report".
The only step I did was the " System Administration -> Configuration -> Mirror Settings -> Join as Async" an fill the blanks. Maybe Im skipping a step?
We have a function that was written for us that allows us to create text files for logging certain aspects to the OS using %Stream.FileCharacter. We had no issues with this until we moved from AIX to Red Hat.
Now it seems the 1st time the function is called, and the file is created the permissions seem to be correct on the file. But as soon as we attempt to write another line to the file using MoveToEnd() it seems the permissions are changed on the file. I have been able to narrow the issue down to the MoveToEnd() by calling the function from different users.
I'm at a loss with configuring the IRIS ODBC driver (v02.10) on my Amazon Linux machine, connecting to a REMOTE IRIS backend. It should be simplified by not requiring a DSN (the app uses a DSN-less connection and generates the connection string). I have
The database is increasing a lot (almost a 1TB) and getting bigger with no sense after migration, the use of the plataform did not increase after the migration so is strange for us this increase.
how can I check everything is ok in the database? for example any table getting bigger.
Hello guys! I need some assistance with these problems I have.
The first one is that I need to execute a Python file, which is at /XY path. This PY is supposed to read an excel file and create a CSV version in /XZ path.
I am quite sure that the PY file is correct, but when using this function I get nothing but this error:
First time setting up a SSL/TLS connection, and I am running into issues when I call it from within a Business Operation. I used openssl to generate a RSA 4096 SHA512 key/csr request for our Active Directory Certificate Service to generate a Certificate Chain for me to use within RedHat. I was
able to connect to our Web Service server using a generic request from terminal, however when I try it from our Business Operation I am running into issues.
I tested the SSL/TLS connection using the following commands from the terminal...
DEVCLIN>set request=##class(%Net.HttpRequest).%New()
