Disk space requirements

Ensure that the system you choose has the necessary disk space for Q Replication or Event Publishing to meet expected performance demands. The main installation-time requirements include Db2® and IBM® MQ.

The total amount of required disk space is the sum of the components that are listed in Table 1, with slight variation depending on the product installed.

  • If you plan to use a target other than a Db2 database, you can specify which type of database while installing replication, and the installation program installs a relational wrapper for that database.
  • If a compatible edition of Db2 Version 9.7 database system is not already installed, Db2 Restricted Enterprise Edition will be installed.
  • The installer needs temporary disk space while the product is being installed.

Additional disk space considerations:

  • The disk space requirements vary depending on your configuration and the type of disk drive that you have.
  • Windows: Significantly more disk space might be required on FAT drives with large cluster sizes than NTFS drives.
  • Include required client software and communication products when you calculate the amount of disk space that is needed for your installation.
