HP OpenVMS 8.x manual @Sys$Startupess$Ladstartup.Com

Parameter	Description
	6	64 blocks
	7	128 blocks
	8	256 blocks
CACHE_BUCKETS	Determines the number of buckets in the cache. The default is 512. Numbers larger
	than 16384 might adversely affect performance. To reach a desirable cache size,
	consider increasing the BUFFER_SIZE parameter.
MAXIMUM_SERVICES	Sets the maximum number of services that can be defined at one time for the server.
	The value of this parameter must be a power of 2. The default and minimum value
	is 256 (adequate for most circumstances); the maximum value is 1024. Each service
	descriptor consumes nonpaged pool; however, unused services consume 4 bytes
	each.
WRITE_LIMIT	The number of asynchronous write operations that can be outstanding for the
	server at any time. The default is 0 (no outstanding asynchronous write operations).

NOTE: As indicated in the file comments, the LAD cache comes out of nonpaged pool. If you increase the cache significantly, you might need to increase the nonpaged pool SYSGEN parameters (NPAGEDYN and NPAGEVIR).

3.Determine which network device will be used for InfoServer LAD operations. You can use any network device that is visible to OpenVMS. Typically, any network device that works with DECnet or TCP/IP Services for OpenVMS should work. Use the LANCP command SHOW CONFIGURATION to determine which device to use, as described in Section B.2.1 (page 191).

For this release of OpenVMS, the LASTport protocol runs on only a single network device. To enable this device, copy the SYS$STARTUP:ESS$LAST_STARTUP.TEMPLATE file to the SYS$STARTUP:ESS$LAST_STARTUP.DAT file, and then open the SYS$STARTUP:ESS$LAST_STARTUP.DAT file and make the following changes:

a.Remove the comment character (!) from the line that has the following text: DEVICE =

(). Within the parentheses, specify the device name. For example: DEVICE = (EIA).

b.Comment out the line that specifies ALL_CONTROLLERS = ON (comment out a line by inserting an exclamation point (!) at the beginning of the line).

The following example shows the SYS$STARTUP:ESS$LAST_STARTUP.DAT file with the suggested changes made (shown in bold):

!++

!This file will be used to set the appropriate LASTCP qualifiers. The following

!LASTCP qualifiers: ALL_CONTROLLERS, CHECKSUM, TRANSMIT_QUOTA, or SLOW_MODE

!can be set by using the following statement format:

! LASTCP qualifier = 1 to enable e.g. SLOW_MODE = 1 enables SLOW_MODE

!LASTCP qualifier = 0 to disable e.g. SLOW_MODE = 0 disables SLOW_MODE

!The remaining LASTCP qualifiers will require the appropriate value settings.

DEVICE	=	(EIA)	! Uncommented; device name specified
! TIMEOUT		= n	minimum interval in seconds
! CIRCUIT_MAXIMUM		= n	maximum number of nodes
! GROUP		= n	Group number
! NODE_NAME		= name	Node name
! CONTROLLERS		= ([{controller letter,}...]) Controller list
! TRANSMIT_QUOTA		= n	Number of transmit buffers
!--
!ALL_CONTROLLERS = ON			! Commented out

4.Add the following line to the system startup file SYS$MANAGER:SYSTARTUP_VMS.COM:

@SYS$STARTUP:ESS$LAD_STARTUP.COM

5.If you changed any SYSGEN parameters, run AUTOGEN and reboot (for information about running AUTOGEN, see Section 7.22 (page 144)). If no SYSGEN parameters were changed,
