Revive the Down Half of the Mirrored Disk
If you shut down half of $SYSTEM and other mirrored disks before applying the new RVU, revive
the disks now. For instructions on how to bring up the downed half of a mirrored disk, see the
Guardian User's Guide.
Start User and System Applications
You can now start your application software. Follow your site’s procedures for executing the system
configuration and startup (command) files to accomplish this.
DSM/SCM is often started automatically by a system command file. If not, you must start it manually
as described next.
Before Starting DSM/SCM
Initialize SQL for NonStop SQL/MP
1. Check that TMF is started:
> TMFCOM STATUS TMF
2. Save a copy of the existing ZZSQLCI2 file on the $SYSTEM disk. For example:
> FUP DUP $SYSTEM.SYSTEM.ZZSQLCI2,$SYSTEM.BKUPZSQL.*, SAVEALL
3. Enter:
> SQLCI INITIALIZE SQL; EXIT;
4. Copy the ZZSQLCI2 file saved previously back to the $SYSTEM disk. For example:
> FUP DUP $SYSTEM.BKUPZSQL.ZZSQLCI2, $SYSTEM.SYSTEM.*, SAVEALL
NOTE: ZZSQLCI2 is a temporary file that contains the SQLCI2 program. SQLCI2 is the
process through which the NonStop SQL/MP conversational interface (SQLCI) communicates
with the NonStop SQL/MP executor to request various functions. After SQL initialization is
complete, ZZSQLCI2 is renamed and becomes the permanent SQLCI2 program.
HP recommends that you always have a current backup copy of the
$SYSTEM.SYSTEM.ZZSQLCI2 file in case you need to initialize SQL later for some reason. If
you cannot find a copy of ZZSQLCI2 on the $SYSTEM disk, use DSM/SCM to export the file
from the software archive. (ZZSQLCI2 is a component file of the TSQLCI2 product, T9198.)
For more information, see the SQL/MP Installation and Management Guide. For information
on exporting the file from the Archive, see the DSM/SCM User's Guide.
Although NonStop SQL/MP requires that you initialize SQL before you start DSM/SCM, NonStop
SQL/MX does not require this step. For information about installing NonStop SQL/MX, see the
SQL/MX Installation and Management Guide.
