• Hardware Server Specs for the JAMS Client
• Supporting JAMS in a Virtual Environment

.NET Framework 

The JAMS Client, JAMS Scheduler, and JAMS Windows Agent require .NET Framework 4.8. If it is not installed, the JAMS installer displays a message and attempts to install the .NET Framework.

Microsoft Message Queue (MSMQ)

The JAMS Scheduler requires the Microsoft Message Queue (MSMQ). When installing the JAMS Scheduler, the setup will check for the MSMQ and, if it is not installed, will ask you to confirm that you want to install it.

NOTE: MSMQ is included with Microsoft Windows, but it is optional and not installed by default.

Microsoft SQL Server

The JAMS Scheduler requires Microsoft SQL Server 2019, 2017, 2016, or 2014. The SQL Server does not need to be installed on the same machine as the JAMS Scheduler. The database is fully supported in clustered configuration.

If you or your DBA choose to install the JAMS Scheduler component, the setup will first check for a connection to an SQL Server. If the server not installed, the setup will ask to install the SQL Server 2019 Express Edition.

You also have the option of using a SQL Server on a different machine. Please note that when the installer checks for the SQL Server, it only looks for the default instance names of MSSQLSERVER and SQLEXPRESS.

If you have a different instance preference, decline the SQL Express installation and specify your preferred instance when the JAMS installer asks for the SQL server name and instance.

To run SSISDirect Execution Method Jobs, the Client Tools Backwards Compatibility and Client Tools SDK Shared Features are required. If you see an error message indicating an Invalid Class Exception while editing an SSISDirect Job, ensure the latest SQL Server Management Studio is installed.

PowerShell

JAMS Supports PowerShell V3 and higher.
The JAMS Client component includes a JAMS PowerShell Module that contains JAMS cmdlets and a JAMS Provider. PowerShell is not required, but you must install PowerShell before installing JAMS to use the JAMS PowerShell Module. If you install PowerShell after installing the JAMS Desktop Client, reinstall the JAMS Desktop Client to access the JAMS PowerShell Module.

NOTE: JAMS V6.X Agents support PowerShell V2, and may be connected to JAMS V7.X Scheduler Servers. By leveraging a V6.X Agent, V7 users may run PowerShell V2. 

Hardware Server Specifications for the JAMS Scheduler

• Processor: Dual Core ~2.5 GHZ (x86 or x64)
• Memory: 8 GB
• Disk Space: 10 GB, in addition to the disk space required by the OS.

These are the minimum system requirements that can support running thousands of jobs per day. Heavy loads, for example, over 100,000 jobs per day, will require more resources.

For database planning, the JAMS test lab runs approximately 1,000 jobs per day using one instance of JAMS. Retaining 30 days of information generates a database approximately 110 Mb in size.

For sites running over 100,000 Jobs per day

Based upon customer implementations where more than 100,000 jobs are executed each day, the JAMS installation should consist of:

• Two Windows servers, each with Dual Quad 3.2 GHz CPUs and 64 GB of RAM (or more).
• Specifically, one of the above servers hosting the JAMS Scheduler and the second server reserved for the SQL Server with multiple high-speed SCSI drives.

Hardware Server Specs for JAMS Agents

• Processor: 1 GHZ (x86 or x64)
• Memory: 1 GB
• Disk Space: 75 MB

Hardware Server Specs for the JAMS Client

• Processor: 1 GHZ (x86 or x64)
• Memory: 1 GB
• Disk Space: 300 MB

Supporting JAMS in a Virtual Environment

You can run JAMS on any supported operating system in a virtualized environment, such as VMware and HyperV. JAMS is supported in cloud-based environments such as AWS or Microsoft Azure.
