Administering Satellites Guide and Reference

Disk Requirements

This section describes the minimum amount of disk space that is required to install the DB2 control server component, create the DB2CTLSV instance, and create an empty satellite control database (SATCTLDB). You should add these numbers to the base requirements for DB2, which can be found in the "Planning for Installation" section of the appropriate DB2 Quick Beginnings book. These estimates do not include the disk space required for the operating system, application, or communication products. Consult each product's documentation for these values.

Windows NT

The recommended minimum disk space for the DB2 control server, plus an empty satellite control database, is 13 MB.

AIX

The recommended minimum disk space for the DB2 control server, plus an empty satellite control database, is as follows:

• Under the INSTHOME/db2ctlsv and INSTHOME/sqllib directory, is 23.2 MB, where INSTHOME represents the home directory of the instance.
• Under the /usr directory, is 0.4 MB

As you add groups, satellites, and scripts, and use the satellite control database, the satellite environment will consume more disk space. Formulas for estimating the size of your production SATCTLDB database can be found at the following URL: www.software.ibm.com/data/db2/library/satellite

Note:

Synchronization logs can consume rather large amounts of disk space unless they are periodically purged.
