HP OpenVMS Systems Documentation

Returns status and identification information about the local system (or about a node in the local mixed-architecture OpenVMS Cluster system, if your system is part of an OpenVMS Cluster).

Format

F$GETSYI (item [,node-name] [,cluster-id])

Return Value

Arguments

item

Indicates the type of information to be reported about the local node (or about another node in your OpenVMS Cluster, if your system is part of an OpenVMS Cluster). Specify the item as a character string expression.

You can also specify any of the system parameters listed in the HP OpenVMS System Management Utilities Reference Manual.

node-name

Specifies the node in your OpenVMS Cluster system for which information is to be returned. Specify the node as a character string expression. You cannot use the asterisk (*) and the percent sign (%) wildcard characters to specify the node-name argument.

cluster-id

Specifies the cluster node identification number for which the information is to be returned.

To get information for all the nodes in a cluster, use the F$CSID lexical function to obtain each cluster system identification number, and use the cluster-id argument of F$GETSYI to gather information about each node.

Description

The F$GETSYI lexical function invokes the $GETSYI system service to return status and identification information about the local system (or about a node in the local OpenVMS Cluster, if your system is part of a cluster). The F$GETSYI function returns information on the items that can be specified with the $GETSYI system service. For more information about the $GETSYI system service, see the HP OpenVMS System Services Reference Manual.

You can specify the node for which you want information by supplying either the node-name or the cluster-id argument, but not both.

Table DCLI-10 lists the items you can specify with the F$GETSYI lexical function.

Examples

$ SYSID = F$GETSYI("SID")
$ SHOW SYMBOL SYSID
  SYSID = 19923201  Hex = 01300101 Octal = 000401
      

This example shows how to use the F$GETSYI function to return the information in the system identification register. Use quotation marks (" ") around the argument SID because it is a string literal. The value returned by F$GETSYI is assigned to the symbol SYSID. Because a node is not specified, information about your current node is returned.

$ MEM = F$GETSYI("CLUSTER_MEMBER", "LONDON")
$ SHOW SYMBOL MEM
  MEM = "TRUE"
      

This example uses the F$GETSYI function to determine whether the node LONDON is a member of the local cluster. The return value TRUE indicates that the remote node LONDON is a member of the cluster.

$ LIM = F$GETSYI("IJOBLIM")
$ SHOW SYMBOL LIM
  LIM = 16   Hex = 00000010  Octal = 00000000020
      

This example uses the system parameter IJOBLIM as an argument for the F$GETSYI function. This argument returns the batch job limit for the current system.

$  DECNETVERS = F$GETSYI("DECNET_VERSION")
$ SHOW SYMBOL DECNETVERS
  DECNETVERS = "00050D01"
$ DECNETPHASE = F$INTEGER(F$EXTRACT(2,2,DECNETVERS))
$ SHOW SYMBOL DECNETPHASE
  DECNETPHASE = 5   Hex = 00000005  Octal = 00000000005
      

This example shows how to use F$GETSYI to return the DECnet version, using the DECNET_VERSION item.

$ RADCPU = F$GETSYI("RAD_CPUS")
$ SHOW SYMBOL RADCPU
  0,0,0,1,1,4,1,5
      

This example uses the system parameter RAD_CPUS as an argument for the F$GETSYI function. This argument returns a list of RAD,CPU pairs, separated by commas. In this example, the first RAD,CPU pair is 0,0, the second pair is 0,1, and so forth.

RAD is supported on AlphaServer GS series systems and starting from OpenVMS Version 8.4, support is extended to NUMA capable Integrity servers.
