Initialize OnLine

Initialize OnLine
OnLineprompts you for confirmation that you wish to initialize immediately
using these current values:
Do you really want to continue? (y/n)
WARNING: The root dbspace will be initialized.
All previous data will be destroyed.
When you initialize OnLine starting from theDB-Monitor Initialize option
(disk parameters screen), you are initializingboth disk space and shared
memory. When you initialize disk space, you automatically re-create a new
OnLine database server and destroy all existing data in that space.
Enter y to direct thetbinit process to initialize both OnLine disk space and
shared memory.
Ifyou enter n, the changed parameter values are retained in the configuration
file and DB-Monitor returns to the Parameters menu.
Ifyou receive any error messages as OnLine attempts to initialize, turn now
topage 1-60. Otherwise, OnLine displays messages as the initialization
proceeds. When initialization is complete, OnLine is in quiescent mode.
AfterOnLine is initialized, continue with the remaining tasks to prepare your
system to receive data:
■Set your environment variables
■Modify UNIX startup and shutdown scripts, if desired
■Create blobspaces and additional dbspaces, if desired
Set Your Environment Variables

youloaded the software. This section instructs you in setting two additional
environment variables:
