How do I determine which model fax modem is being used?

  • Log in as root
  • Check the VSIFAX status to determine your modem names:

  • Example output:
[root@firestorm log]# egrep "Multi|MT" $VSIFAX/spool/logs/modem1
14.34.53.401: :                 END,LOG,SYS,EVT,T30,QRY,MTP,TRM
14.34.55.009: : Modem manufacturer    : Multi-Tech Systems
14.34.55.011: : Modem model           : MT5634ZBA-USB
14.34.55.012: : Modem entry used      : Multi-Tech with 56k Lucent chipsets

What is the procedure to restore an Eclipse database server?

If the need arises to restore the Eclipse database, we recommend following the general procedure below:

  • Whenever possible, backup the existing system
  • Whenever possible, move the existing /u2 filesystems to a new location and create new /u2 filesystems
  • Restore the database filesystems
  • Start the UniVerse database, SYSTEM.ADMIN and JBoss application server

If the need arises to restore an Eclipse database server from bare metal, we recommend following the general procedure below:

  • Install the OS (Red Hat Enterprise Linux or AIX) using the DVD media
  • Configure the OS for use with Eclipse
  • Restore the OS configuration files (i.e. users, printers, email relay configuration, etc.)
  • Install and configure the UniVerse database and VSIFAX
  • Restore the Eclipse filesystems (/u2/eclipse, /u2/pdw, etc.)

What is the typical directory structure of an Eclipse database server?

A typical Eclipse database server running AIX or Linux contains the following important directories:

  • /u2: base directory for Eclipse installation
    • /u2/eclipse: Eclipse database
      • /u2/eclipse/modules: contains the JBoss application server and SYSTEM.ADMIN utility
      • /u2/eclipse/ereports: default location of Eclipse Reports temp space and archives
    • /u2/pdw: PDW database files
    • /u2/vsifax: VSIFAX installation
      • /u2/vsifax/lib: VSIFAX configuration files
      • /u2/vsifax/spool/logs: VSIFAX log files for troubleshooting purposes
    • /u2/uv: UniVerse database
    • /u2/unishared: UniVerse database shared files
    • /u2/uvinstall: UniVerse database installation files
    • /u2/uvtmp: UniVerse database temp space
    • /u2/UTILS: miscellaneous Eclipse utilities external to the core application
  • /usr/spool/uv: UniVerse spooler temp space, configuration and driver files
