Server Hardware and Software Requirements

Server Requirements

Install Rosetta and the Oracle database on dedicated servers with the specifications listed in the table below.

All the Rosetta application servers that you are using must be dedicated to Rosetta only. If you are using a separate Oracle database server, this server may be shared.

Specification Per Server
Specification	Description
Operating system/platform	Red Hat Enterprise Linux 8.9
CPUs *	Minimum of 8
RAM *	Minimum of 24GB
Media for data exchange	FTP and an Internet connection (see Communication Requirements) CD-ROM drive for data and software exchange (in case FTP is temporarily unavailable, or if Ex Libris has approved work without an Internet connection)
Database **	Oracle 64-bit The installation of the database in Oracle Real Cluster configuration is supported.
Additional server software	C-shell package (csh or tcsh), as part of the operating system Linux platform GCC, as part of the operating system Oracle RDBMS add-on software **

* Consult with the Ex Libris Sizing Manager

** Installed by Ex Libris to ensure full compatibility with Rosetta

If you are configuring two or more servers, contact your Ex Libris representative to discuss the exact production server specifications required, including the required number of CPUs and RAM. The production server specifications are dependent on the database size and the number of concurrent users.

For detailed operating system requirements, refer to the Operating System Requirements for Red Hat Enterprise Linux document.

For each of the operating system versions, Ex Libris recommends that you install the latest operating system update level.

File System and Disk Space Requirements

Each physical disk that will be used by Ex Libris should be mounted on a separate file system. The names of the file systems should be /exlibris,
/exlibris1, /exlibris2, and so forth.

A file system named /exlibris, with a minimum size of 50 GB, is mandatory. It will be used exclusively for all software and configuration tables and files that will be installed by Ex Libris. Mount the /exlibris file system directly on the server.

The /exlibris file system cannot be a soft or symbolic link to any alternatively named file system.

The Rosetta database files can be placed in any of the file systems
(/exlibris, /exlibris1, and so forth). The Oracle software installation and database creation is performed by Ex Libris staff as a part of the Rosetta installation process.

The following table lists the minimal disk space requirements for running and maintaining Rosetta software and data.

Disk Space Requirements
Software and Data	Minimum Size *	File System	Server
Rosetta and Oracle software	50 GB	/exlibris	All servers
Oracle DB size *	At least 200 GB	/exlibris or /exlibris1, /exlibris2, /exlibris3	Oracle server
RAM *	At least 16 GB		All servers
Swap space *	At least 16 GB		All servers
/tmp *	At least 2 GB		All servers

* Consult with the Ex Libris Sizing Manager

When Rosetta is installed on more than one server, NFS shared disks are required. The following table lists the partitions that must be mounted on each server, as well as recommended mount point names.

Partitions
Use	Minimum Size *	Accessed By	Mount Point
Deposit storage *	At least 50 GB	Deposit and Staging servers	/deposit_storage
Staging storage *	At least 50 GB	Staging and Permanent servers	/operational_storage
Permanent storage *	At least 50 GB	Permanent and Staging servers	/permanent_storage
Operational Shared *	At least 50 GB	All Staging servers	/operational_shared

* Consult with the Ex Libris Sizing Manager

The above information is meant to provide general guidelines for determining the minimal disk space requirements. The exact disk space required should be determined in conjunction with your Ex Libris representative.

The above disk space requirements enable support of the following:

Reorganization of the database (as part of the periodic maintenance of the database) with minimal downtime
The above disk space requirements do not include:
System disk requirements for operating system overhead
Disk space needed for running Oracle in archive-log mode (see Backup and Recovery Media and Procedures)
Disk space requirements for backup at large sites (see Backup and Recovery Media and Procedures)
Any type of data redundancy, such as RAID 1, RAID 5 or RAID 0/1 solutions
Rosetta upgrade requirements

To upgrade during the post-STP stage, allocate twice the amount of disk space for the upgrade as you have available for the current version and database.

Storage Requirements

The following are the storage requirements for Rosetta:

Storage used for application and database (/exlibris)
- Supports any protocol (local file system, FCP, iSCSI, etc.
- Minimum performance recommendations:
  - Physical disks at least 75MB/Secs transfer rate
  - Dedicated NIC for storage (1Gb minimum)
  - Minimum 1500 IOP/Sec with response time <= 8 milliseconds (database only)
Storage for repositories (operational and permanent)
Supports the following protocols:
- NFS
- CDMI
- S3
- Any POSIX-compliant
- Others, via custom plugin/adaptor

The above information is meant to provide general guidelines for determining the minimal performance requirements. The exact transfer rate and IOP/Sec number required should be determined in conjunction with your Ex Libris representative.

Character Set

Ex Libris uses the UTF8 character set for all its products.

Backup and Recovery Media and Procedures

Backup and recovery procedures and their selected media are the customer's responsibility.
