Preparing your database for an upgrade

Before you upgrade the BMC Remedy IT Service Management, prepare your database correctly, as described in the following topics:

To avoid a decline in the BMC Remedy AR System server performance, BMC recommends the following:

  • Do not use a firewall between the AR System server and database tiers. This can impact performance significantly.
  • When possible, set up a high-speed backbone between the AR System server and the database server.
  • If using Ethernet, install the BMC Remedy AR System server and the database server on a separate switched network that is isolated from other network traffic.
  • Avoid putting a wide-area network between the AR System server and the database server.
  • Make sure that each network device between the AR System server and the database server is communicating at the maximum bandwidth.
  • If you are planning to install CMDB or ITSM applications in addition to BMC Remedy AR System, the following minimum space is required:
    • 2 GB for the data file
    • 1 GB for log and temp files
      When installing more than one ITSM application, add 2 GB to the data file and 100 MB to the log file size for each additional application. BMC recommends at least 2 GB of disk space for the database. Depending on the number of records your system handles and the specific type of database you are using, however, you might need more than this. If you do not have 2 GB or more before beginning the installation, you might run out of free space during installation. As the transaction log fills up, the BMC Remedy AR System suspends operation. When the transaction log is completely full, the BMC Remedy AR System writes a message to the BMC Remedy AR System error log and the installation terminates.

      Note

      • In BMC Remedy AR System 8.1, the installer displays a warning message indicating the required space for additional installation of CMDB or ITSM applications.
      • If the transaction log fills during the installation and the installation fails, clear the transaction log, and then increase the size of the transaction log before reinstalling the product.

Note

A common issue is that a router's Auto Negotiate option can incorrectly set the router to 10 MB Half Duplex. NICs, routers, and other network devices then agree on the fastest speed to communicate together, but that speed is usually too slow. To remove this variable, if all the network devices can communicate at 1 GB Full Duplex, set them as such, and disable the Auto Negotiate option on the router.


For technical assistance on installing your database, contact the database vendor.
