HP stronglyB suggests that you use LD devices to support partitioned hard?  drives. See the DCL command LD HELP for more information. 3 Qualifiers /CLASS /CLASS=className> Specifies a subset of the complete LASTport Disk (LAD) name space.A The purpose of class names is to subdivide name spaces so thatD clients see only those names that are meaningful to them. The useD of class names also allows two services to have the same name and! not conflict with one another.@ You can, for example, use different class names for d ifferent: on-disk structures that several client systems use. You= might use SERVICEA/CLASS=ODS-2 for some client systems and@ SERVICEA/CLASS=ISO_9660 for other client systems. The serviceB has the same name, SERVICEA, but the class names are different.C The class name you use depends upon the client systems that will? connect to the service being created. The default class nameB is ODS_2. For example, OpenVMS systems use the ODS_2 name spaceC when attempting to mount an I nfoServer device. Note that OpenVMS@ clients can solicit only those services that are in the ODS_2 service class.'

The service with the highest service rating is selected.C The system adjusts the dynamic service rating based on load. YouD can also set a static rating between 0 and 65535. The system does not adjust static ratings.@ One use of static ratings is to migrate clients from one copy> of a service to another. If you set a static rating of 0 onA services you want to migrate clients away from, no new clientsC will connect to a 0-rated service; instead, they will connect toD higher-rated services. When all current clients have disconnected, from a service, you can safely delete it. /READAHEAD /READAHEAD (Default) /NOREADAHEADA When a disk read is required to fill a cache block, /READAHEADB specifies that the read is to be from the first block requested< to the end of the bucket boundary. Readahead can speed upC sequential operations by pre-loading disk blocks that are needed into the cache.< If you specify both /READAHEAD and /READBEHIND, any blockA requested within a cache bucket causes the entire bucket range' of blocks to be read into the cache. /READBEHIND /READBEHIND /NOREADBEHIND (default)B When a disk read is required to fill a cache block, /READBEHIND< specifies that the read is to include all blocks from theA beginning of the cache bucket boundary up to and including the requested blocks.< If you specify both /READAHEAD and /READBEHIND, any blockA requested within a cache bucket causes the entire bucket range' of blocks to be read into the cache. /READERS, /READERS=number (default READERS 1000) /NOREADERSB Specifies the maximum number of simultaneous client connectionsC allowed for read access. The default is 1000 readers. A value of! 0 indicates write-only access.D If a client requests read-only or read/write access to a service,( the system counts this as one reader. /WRITERS /WRITERS /NOWRITERS (default)D Specifies that the service is to allow access to a single writer. 3 Examples$ 1.$ SHOW DEVICE MOVMAN$DQA0:/fullJDisk MOVMAN$DQA0:, device type Compaq CRD-8322B, is online, file-orientedJ device, shareable, served to cluster via MSCP Server, error logging is enabled.6 Error count 0 Operations completedE Owner process "" Owner UIC [SYSTEM]E Owner process ID 00000000 Dev Prot S:RWPL,O:RWPL,G:R,WE Reference count 0 Default buffer size  512E Total blocks 16515072 Sectors per track 63E Total cylinders 16384 Tracks per cylinder 16" $ MOUNT/SYSTEM dqa0 OVMSIPS11 Volume is write locked) OVMSIPS11 mounted on _MOVMAN$DQA0: $ InfoServer: InfoServer> CREATE SERVICE VMS_SIPS_V11 _MOVMAN$DQA0:D %INFOSRVR-I-CRESERV, service VMS_SIPS_V11 [ODS-2] created for _MOVMAN$DQA0:.D This example shows commands you might enter to create a service for a CD device:D o The SHOW DEVICE . . . /FULL command displays a complete list1 of information about the _MOVMAN$DQA0 CD.; o The MOUNT/SYSTEM mounts the OVMSIPS11 volume on the _MOVMAN$DQA0: CD.C o The InfoServer CREATE SERVICE command creates the VMS_SIPS_+ V11 service on the _MOVMAN$DQA0 CD.! 2. $LD CREATE KIT1/SIZE-100000 $DIRECTORY KIT1 Directory DKB0:[DISKS]?

The command in theD second example displays all sessions, even those with no client connections.N wwWȭ1 SPAWNC Spawns a process to execute a DCL command. If you do not enter aD command, the command terminal is attached to the spawned process.A If you do enter a command, that command is executed, and, uponD completion of the command, control returns to the parent process. Format SPAWN [DCL Command] 2 Example InfoServer> SPAWN DIRECTORY . . . (output) . . O . InfoServer>B The command in this example spawns a process to execute a DCLC DIRECTORY command. Following execution of the command, control' returns to the InfoServer process. wwgȭ1 START 2 SERVER@ This command starts the LASTport/Disk server and sets various$ server and cache characteristics.< Usually, this command is executed by SYS$STARTUP:ESS$LAD_? STARTUP.COM using data from SYS$STARTUP:ESS$LAD_STARTUP.DAT.@ HPP strongly recommends that you make all modifications in the( SYS$STARTUP:ESS$LAD_STARTUP.DAT file.@ You can use the START SERVER command interactively to use itsB qualifiers to change server settings so long as no services are currently defined.& NOTE> If you enter the START SERVER command directly, you must? specify all four qualifiers, or the system will revert to using default values. Format START SERVER Q 3 Qualifiers /BUFFER_SIZE /BUFFER_SIZE=nA The InfoServer block cache is structured as an array of fixed-A size buffers (also called buckets.) The /BUFFER_SIZE qualifier; determines the size of each bucket. (The /CACHE qualifer% determines the number of buckets.)B The numeric value of this parameter is an integer between 3 andB 8 inclusive, representing the bucket size in 512-byte blocks as follows: 3 - 8 blocks (default) 4 - 16 blRocks 5 - 32 blocks 6 - 64 blocks 7 - 128 blocks 8 - 256 blocks The default value is 3.B Bucket sizes that are larger than 32 blocks are not appropriate@ for most users. The OpenVMS client segments I/O requests thatB are larger than 31 blocks into 31-block chunks, and the default< bucket readahead behavior might result in unnecessary I/O activity to the disk. /CACHE0 /CACHE = number-of-buckets (default = 512): The InfoServer blocSk cache is structured as an array of@ fixed-size buffers (also called buckets. The /CACHE qualifierB determines the number of buckets in the cache. The /BUFFER_SIZE0 qualifier determines the size of each bucket.> Numbers larger than 16384 can adversely affect performance.> Consider increasing the /BUFFER_SIZE qualifier to reach the desired cache size. /MAXIMUM_SERVICES4 /MAXIMUM_SERVICES = maxservice (default = 256)= Sets the maximum service count for the servTer. This is the> maximum number of services that can be defined at one time.C Each service descriptor consumes non-paged pool; however, unused+ service slots consume only 4 bytes each. The maximum value is 1024. /WRITE_QUOTA$ /WRITE_QUOTA = n (default = 0)A Number of simultaneous synchronous writes permitted within theB server. The default of zero means that all write operations are performed synchronously. 3 Example $ InfoServer SHOW SERVERUF Node BILBO [HP rx2600 (900MHz/1.5MB)] running OpenVMS XAR8-D2Y' LASTport/Disk Server Version 1.2= Max Services: 64 Write Quota: 0D Cache Buckets: 2048 Cache Bucket Size: 32 blocks$ Cache Size: 33554432 bytes> Hits: 0 Hit Percentage: 0% Misses: 0= Current Sessions: 0 Peak Sessions: 00 Read WriteV0 Requests: 0 00 Blocks: 0 00 Errors: 0 00 Aborted: 0 00 Conflicts: 0 0/ $ InfoServer START SERVER/MAXIMUM_SERVICES=128 /CACHE=2048/BUFF=5/WRITE=09 %INFOSRVR-I-STARTED, LASTport/Disk server started. $ InfoServer SHOW SERVERF Node BILBO [HP rx2600 (900MHz/1.5MB)] running OpenVMS XAR8-D2Y' W LASTport/Disk Server Version 1.2: Max Services: 128 Write Quota: 0A Cache Buckets: 2048 Cache Bucket Size: 32 blocks!

The second command starts the@ server and increases the maximum number of services for theA server. The third command displays the new information aboutB the server, showing the increases maximum number of services.ww
