Oracle Audio Technologies B10508-01 manual Using Autogen

HP OpenVMS Alpha SYSGEN Parameters

** 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.

Additional Information: For more information about the reserved memory registry, refer to the Hewlett-Packard documentation.

To review memory reservations on your node, run the following command:

$ show memory/reserved

System Memory Resources on 13-JUL-2001 09:57:11.72

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,
