HP OpenVMS Alpha SYSGEN Parameters
3-14 Oracle9i Installation Guide Release 2 (9.2.0.2) for HP Alpha OpenVMS
** Reserved memory size = greater than created SGA size = **
** Please reduce reserved memory size to avoid wasting memory. **
** Memory was not reserved for the SGA. SGA size = **
** There might be performance advantages to allocating memory for
the SGA in the VMS reserved memory registry. **
If memory is reserved for an SGA, but not enough memory is reserved, then the
instance startup will fail
. In this case, the amount of reserved memory must be
adjusted, AUTOGEN must be run, and the system must be rebooted . For example,
to expand the SGA to 6.5 GB for the TEST instance, use the following commands:
$ MCR SYSMAN
SYSMAN> RESERVED_MEMORY REMOVE ORA_TEST_SGA
SYSMAN> RESERVED_MEMORY ADD ORA_TEST_SGA/SIZE=6656/ALLOCATE/ZERO/PAGE
SYSMAN> EXIT
Then run AUTOGEN and reboot the system.
To avoid rebooting the system, SYSMAN can be used to free the memory
reservation
. Then you may start the instance . The risk is that the system may not
have enough fluid pages to create the SGA
.
Also, the performance advantages of
using reserved memory are not available.
To review memory reservations on your node, run the following command:
$ show memory/reserved

Please consult Hewlett-Packard if you need more information about reserving
memory.
Using AUTOGEN
Because SYSGEN parameters affect the entire operating system, your system
administrator is the only person who should modify them
. Of course at some sites,
