Meridian Application Server Requirements

These requirements are recommended for the following example environments:

Workgroup — 50,000 documents and 15 users, or for demonstration computers
Department — 100,000 documents and 30 users, or for demonstration computers
Enterprise — 500,000 documents and 150 users. Vaults stored in SQL Server or Oracle should not exceed 2 million documents. Vaults stored in Hypertrieve can accommodate many more documents and several hundreds of users.

The preceding examples are general guidelines only. Capacity and performance depend on the specific server configuration and are not guaranteed.

These specifications pertain to Meridian Enterprise only. Meridian can be one system within a larger computing environment that also includes Meridian Explorer, which can serve many times more users than Meridian Enterprise. For information about Meridian Explorer system requirements and deployment, see Meridian Enterprise Server System Requirements. For the best possible performance, see Hypercache . This specification is recommended for SQL Server or Oracle installations on the same computer with Meridian.

Lesser specifications might be insufficient to configure HyperCache. For more information, see Hypercache.

Hardware specifications
Requirement	Workgroup	Department	Enterprise
CPU	Intel® Xeon® E3 or E5	Intel® Xeon® E3, E5, or E7 with 4 to 8 cores	Multiple Intel® Xeon® E5 or E7 CPUs with 8 or more cores
Memory	2 GB or higher depending on the total of all database sizes	16 GB or higher depending on the total of all database sizes	32 GB or higher depending on the total of all database sizes
Storage	1 GB + document storage space on high performance drives. Non-system partition volumes recommended. To calculate the document storage space and to prevent out of disk space errors, see Document Storage Space Requirements.

Dedicated server that is not used for anything other than Meridian and its database engine, SQL Server or Oracle. We recommend only the Enterprise hardware specifications when Oracle or SQL Server are used on the same computer or with multiple active vaults.
One of the Windows Server operating systems (with latest Service Pack) listed in Operating Systems. The operating system should be installed with the roles and services described in Server Role Requirements.
If the vaults will not be hosted on the Meridian application server with the Hypertrieve database engine, a connection to one of the database management systems listed in Database Management Systems.
- If any vaults will use a Meridian Enterprise MS SQL Server 5 (or later) database engine to connect to either a local or remote SQL Server instance, the Microsoft OLE DB Driver for SQL Server (MSOLEDBSQL) must be installed on the Meridian server.
- If any vaults will use the Meridian Enterprise Oracle 5 database engine (not Oracle 3) to connect to either a local or remote Oracle instance:
  - The 64-bit Oracle Data Access Components (ODAC) and Oracle Data Provider for .NET (ODP.NET) version 11.2 or higher must be installed on the Meridian server. For more information about database engine selection during vault creation, see Create a New Vault.
  - A default installation of Oracle is limited to 150 processes. If the database server has more than one CPU, that limit may be reached and cause vault errors, especially during large imports. We recommend that you configure Oracle to allow up to 500 processes.
The vault audit trail feature of the Meridian FDA Module and the subscriptions feature of Meridian Enterprise require a connection to one of the database management systems listed in Database Management Systems.
SQL Server Compact Edition 3.5 (64-bit only) or higher installed in advance. The Meridian Enterprise setup program will check for its existence and show a warning if it is not found. This is the default storage for external lookup tables, the user account database, and local workspace data. It is not used for vault data and is not installed by the Meridian setup programs. An installation package is provided for manual installation.

The lookup tables (but not the user account database or local workspace databases) can also be stored in a server edition of SQL Server. The supported versions of SQL Server are listed in Database Management Systems. Storage in a server edition has the following limitations:
- Lookup table entries will not be included in the vault configuration export (.met) file. Therefore, they cannot be imported for use in another vault unless that vault is also connected to the same database server.
- Lookup tables will not be included in the vault backup snapshots and must be backed up separately.
- Retrieving lookup table entries and using them in custom property pages requires VBScript programming. The database connection strings will be encoded in the scripting, which may pose a security risk for your organization and will require updating if the database server name is changed.
The data can be stored in Microsoft Access tables instead if the following requirements are met:
- An OLE DB driver is installed. Microsoft Office includes a 64-bit OLEDB driver named the Office System Driver that can be used to connect to Access, Excel, and text files. The provider name is Microsoft.ACE.OLEDB.<VersionNumber>.
  
  If Office is not installed, the driver is available as a separate download from the Microsoft Download Center by the name of Microsoft Access Database Engine Redistributable.
  
  For additional information, see Jet for Access, Excel and Txt on 64-bit systems at ConnectionStrings.com.
- The ConnectionString registry setting is configured as described in HKEY_LOCAL_MACHINE\Software\Cyco\AutoManager Meridian\CurrentVersion\Server\UserDatabase
- The TablesDb registry setting is configured as described in HKEY_LOCAL_MACHINE\Software\Cyco\AutoManager Meridian\CurrentVersion\Server
- The WorkspaceDB registry setting is configured as described in HKEY_LOCAL_MACHINE\Software\Cyco\AutoManager Meridian\CurrentVersion\Client
Note:
Depending on how much additional data is stored in Microsoft Access (for example: document subscriptions, audit log), the database can grow to where performance is degraded considerably. For that reason, we do not recommend using Microsoft Access for more than external lookup tables, the user account database, and local workspace data. Store all additional data in SQL Server instead.
One of the Internet Information Services versions listed in Web Servers and Browsers. The minimum IIS components that must be installed for proper operation are described in Server Role Requirements.
- If the Request Filtering feature option Allow unlisted file name extensions is disabled in IIS Manager, the following file extensions must be added to the File Name Extensions list and allowed: .dll,.gif,.png,.js,.css.
- If Meridian Mobile will be deployed, additional requirements must be met as described in Install the Meridian API Service.
- Transport Layer Security (TLS) 1.2 is supported by Meridian 2018 R2 Update 1 and higher.
One of the browsers listed in Web Servers and Browsers (some components are used by Meridian).
Microsoft .NET Framework 4.7.1 Full Profile (the Client Profile is insufficient)
Any additional requirements for specific operating systems or Meridian releases that are documented in the 2021 R2 Release Notes.
