System Requirements and Setup › Installation Prerequisites

Installation Prerequisites

Before you install the product, check the following prerequisites:

• Privileges required

  In order to install CA XCOM Gateway on Microsoft Windows, you must log on to Microsoft Windows as a user with administrator privileges. On UNIX or Linux, you must log on as a user with root privileges.

• System Libraries for Linux

  The CA Embedded Entitlements Manager (EEM) installation requires the library libstdc++.so.6 to exist in the usr/lib directory. This library can be installed from rpm libstdc++ if it has not been previously installed as part of your operating system.

• Database preparation

  CA XCOM Gateway needs access to a DB2 or MySQL database server; the product installer automatically creates the required database tables within a designated database.

  Note:

  • For MySQL, the installer can either create a database or use an existing one.
  • For DB2, the installer is unable to create a database. To create a database, it must be done using DB2 administration tools before installing CA XCOM Gateway.
  • For DB2, the installer is unable to create a database table schema owner. To create a database table schema owner, it must be done using DB2 administration tools before installing CA XCOM Gateway.

    To enable the creation of tables (and optionally, for MySQL only, the creation of a database), the installer requests the following items:

  • The user ID and related password for a database administration user account that has the necessary create and drop structure privileges.

    To enable the database access by CA XCOM Gateway, the installer also requires a copy of the JDBC connector/driver for the appropriate database system. Using DB2, a copy of the JDBC Driver License is needed.

  • Database Engine Considerations:
    • The default engine for MySQL is InnoDB and it cannot be changed to any other engine.
    • Other engines like MyISAM do not support foreign key constraints, as well as not supporting transactions.
    • MyISAM (unlike InnoDB) tables can become corrupt when there is a server crash.
    • MyISAM cannot be used when the data integrity is a priority, according to recommendation from various sources.

• Samba Support/ UNC Path Support

  The CA XCOM Gateway installer requires a copy of samba support java library, to support file transfers to and from UNC paths. This is an optional step in installation process. Samba support can be added after installation.

• Free disk space

  Approximately 1 GB of disk space is required for the software files that a full CA XCOM Gateway product installation creates. In addition, disk space is required for the CA XCOM Gateway database, logs, and trace files, and for the CA XCOM Gateway staging area that CA XCOM Gateway stores uploaded files. The amount of space that is needed varies depending on:

  • The size of the database
  • The number and size of uploaded files
  • The configured retention periods
