PatOrg system requirements

What is at least required to operate PatOrg and what is recommended

Oracle database

Due to the complex Oracle compatibility with Linux, the combination of Oracle database and Linux version that can be used must be discussed in advance.
Documents can be stored directly on the app server or on a separate file server.
HDDs are generally not supported for the app and database server, but can be used for the file server.
Storage requirements are determined individually based on customer requirements.
Two virtual machines are required for 20 users or more.
A Windows operating system is required for the app server.
No other database should be operated on the virtual machine for the Oracle database.
In general, the PatOrg-Server benefits more from a higher clocked CPU than from many threads.
A RAID-5 or shared storage with HDD/SSD pool can lead to significant performance losses.
Only DE or EN are supported as system languages.
IPv6 must not be disabled.
A service user in AD is mandatory, which is added to the local administrator group on each VM.
A current browser must be pre-installed.
An installed .NET Framework 4.8 is a prerequisite on the app server.
A share is needed on which the service user and PatOrg users have read and write access.
During initial setup and later upgrades, third-party security tools/antivirus scanners must be temporarily disabled.
Only native Microsoft Exchange solutions are supported for the Outlook Add-In.
Oracle Express Edition (XE) supports a maximum of 12 users and two Oracle schemas due to its limitations.
