** Reserved memory size =

<size>

greater than created SGA size =

<size>

** Please reduce reserved memory size to avoid wasting memory. **

** Memory was not reserved for the SGA. SGA size =

<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
