#Red Hat Enterprise Linux (RHEL)

3

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.

I am trying to setup a OAuth2.0 configuration to connect to a server within our Network using OAuth2.0. My previous attempt worked, however forgot to capture the steps before I had whipped the System so please bear with me.

I have an SSL/TLS Client configuration setup as we use the setup for our LDAP configuration.

When I go through the following steps within the Terminal, I am getting the following error...

new RHEL server Intel vs AMD

we are looking at replacing our VMS system with Linux :-( yes a sad day!

now the question has become should we go with Intel or AMD. personally I think Intel is the way to go for several reasons.

has anyone seen or heard of an AMD being slower or there is a definite performance of one over the other.

thanks for your feedback.

I am exporting data from Cache using the SQL export wizard. This is on a docker image of Cache hosted on a Linux server.

I select my database, schema, and table, make sure that all columns are being exported, check other settings, and then finish the export.

All server settings look correct and permissions are rwe on the directory. I have tried various directories, including a system level directory. I tried creating the file before I do the export in case there was an issue with creating the files, and I also made sure the created files had rwe permisisons.

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()

I am trying to setup our first SSL/TLS configuration so we can possibly connect to the EMR FHIR server to pull data into the Interoperability engine.

I am running on Red Hat, and created and submitted a openssl CSR request to our Windows ADCS system.

I used the following command to generate the key and CSR request to submit to Windows ADCS

openssl req -new -sha512 -nodes -newkey rsa:4096 -keyout xxxxxxx.key -out xxxxxxxx.csr

Forgive me but our System Administrator who knows how the networking works is OOO...

How does IRIS know which local adapters are available to populate in an Inbound or Outbound TCP Adapter Object? We recently moved from HealthShare Health Connect 2018.1.3 to IRIS HealthShare Health Connect 2022.1. When we migrated we moved the VIP over to the new box and set it at the hardware level.

On RedHat when I do an ifconfig I have two ens192 adapaters..

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.

Linux and links

If I create a link does root use it? (it’s in profile.d dir)

I'm trying to use a shortcut for a filepath as such: anyone have any thoughts?

PROCAUTO = /JRNDSK/ProcAuto_share

yet in the application it isn't recognizing it.

Here’s the scenario. (link is in place) that my manager thinks maybe an issue.

We just upgrade from cache 2016.2 to IRIS 2020.1.1.

After this upgrade we cannot access to the portal web management, and dont give errors about that just this:

09/28/21-15:59:16:654 (20192) 1 [Utility.Event] Private web server has not started after 5 seconds.

Is this normal?

I followed the guide but dont talk nothing about that.

This is a normal problem when upgrading?

Thanks!!

Database increase a lot

Hello,

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.

Before the migration the logs were like:

07/22/21-17:18:26:304 (19701) 0 Starting Expansion for database /opt/Intersystems/HS/HS_201521705/mgr/cachetemp/. 276 MB requested.

Hello,

We need to upgrade our cache instance from 2016.2 to the latest version.

I find the documentation about the "Upgrade Path" but I cant find where I can get the files to upgrade in the documentation.

Also I cant find how to make this upgrade, they talk about strategies but dont talk how to perform the task to upgrade.

Is there any documentation of how to make and upgrade and where I can get the files?

Hi,

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?

Thanks!!!

Hello,

We have a need to track Database changes over time - down to the SQL level of granularity if possible. Such as: User xyz runs routine ^abc and we get something similar to a changelog that tells us: table A had this value updated, insert, update etc....

Is that possible using IRIS level tools (Audit Log, Journal File, etc...) , is there a way to convert the global sets and kills from the journals into SQL level changes?

Hi,

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?
