1The optional parameter ifi is an internal file identification. The default ifi (ALL) is all the files the current process has opened.
2Specifying the PIO option causes the SHOW PROCESS/RMS command to display the indicated structures for process-permanent file I/O.

The default option is ALL:ALL,NOPIO, designating for display by the SHOW PROCESS/RMS command all structures for all files related to the image I/O of the process.

To list more than one option, enclose the list in parentheses and separate options by commas. You can add a given data structure to those displayed by ensuring that the list of keywords begins with the * (asterisk) symbol. You can delete a given data structure from the current display by preceding its keyword with NO.


Qualifiers

None.

Description

The SET RMS command determines the data structures to be displayed by the SHOW PROCESS/RMS command. (See the examples included in the discussion of the SHOW PROCESS command for an indication of the information provided by various displays.) You can examine the options that are currently selected by issuing a SHOW RMS command.

Examples

#1

SDA>  SHOW RMS
RMS Display Options:  IFB,IRB,IDX,BDB,BDBSUM,ASB,CCB,WCB,FCB,FAB,RAB,NAM,
XAB,RLB,BLB,BLBSUM,GBD,GBH,FWA,GBDSUM,JFB,NWA,RU,DRC,SFSB,GBSB
 
Display RMS structures for all IFI values.
   
SDA>  SET RMS=IFB
SDA>  SHOW RMS
   
RMS Display Options:  IFB
 
Display RMS structures for all IFI values.
 
      

The first SHOW RMS command shows the default selection of data structures that are displayed in response to a SHOW PROCESS/RMS command. The SET RMS command selects only the IFB to be displayed by subsequent SET/PROCESS commands.

#2

SDA>  SET RMS=(*,BLB,BLBSUM,RLB)
SDA>  SHOW RMS
   
RMS Display Options:  IFB,RLB,BLB,BLBSUM
 
Display RMS structures for all IFI values.
      

The SET RMS command adds BLB, BLBSUM, and RLB to the list of data structures that the SHOW PROCESS/RMS command currently displays.

#3

SDA>  SET RMS=(*,NORLB,IFB:05)
SDA>  SHOW RMS
   
RMS Display Options:  IFB,BLB,BLBSUM
Display RMS structures only for IFI=5.
      

The SET RMS command removes the RLB from those data structures displayed by the SHOW PROCESS/RMS command and causes only information about the file with the ifi of 5 to be displayed.

#4

SDA> SET RMS=(*,PIO)
      

The SET RMS command indicates that the data structures designated for display by SHOW PROCESS/RMS be associated with process-permanent I/O instead of image I/O.

SHOW CALL_FRAME

Displays the locations and contents of the longwords representing a procedure call frame.

Format

SHOW CALL_FRAME [starting-address|/NEXT_FP]


Parameter

starting-address

Expression representing the starting address of the procedure call frame to be displayed. The default starting-address is the longword contained in the FP register of the SDA current process.

Qualifier

/NEXT_FP

Displays the procedure call frame starting at the address stored in the FP longword of the last call frame displayed by this command. You must have issued a SHOW CALL_FRAME command previously in the current SDA session to use the /NEXT_FP qualifier to the command.

Description

Whenever a procedure is called using CALLG or CALLS instructions, information is stored on the stack of the calling routine in the form of a procedure call frame. Figure SDA-5 illustrates the format of a call frame.6

The SHOW CALL_FRAME command interprets the contents of the designated call frame and displays whether the call frame was generated by a CALLG or CALLS instruction. If it locates nonzero bits in the portion of the second longword that represents the upper byte of the processor status word (PSW), it presents a message that indicates the fault or trap in effect. For example:


Nonzero PSW Bits (15:8) => Reserved Operand Fault on RET 

SHOW_CALL_FRAME then produces four columns of information:

Figure SDA-5 Call Frame


The SHOW CALL_FRAME command follows this listing with an indication of how many bytes were used to align the call frame to a longword boundary.

For call frames generated by a CALLS instruction, the SHOW CALL_FRAME instruction displays the argument list to the call frame in three columns containing the virtual address of each item, its contents, and its symbolic representation.

All valid procedure call frames begin on a longword boundary. If the specified address expression does not begin on a longword boundary, the call frame is invalid and SDA displays the following message:


Invalid Call Frame:   Start Address Not On Longword Boundary 

If you attempt to format an address that is not a call frame or is an invalid call frame (that is, bit 28 of the second longword is not 0), SDA displays the following message:


Invalid Call Frame:   Bit 28 is Set in "Mask-PSW" Longword 

When using the SHOW CALL_FRAME/NEXT_FP command to follow a chain of call frames, SDA signals the end of the chain by this message:


%SDA-E-NOTINPHYS, 00000000 : not in physical memory 
This message indicates that the saved FP in the previous call frame has a zero value.

The SHOW CALL_FRAME commands in this SDA session follow a chain of call frames from that specified in the FP of the SDA current process.

Note

6 In Figure SDA-5, the second longword contains the stack pointer alignment (SPA) bits, which indicate the zero to three bytes needed to align the frame to a longword boundary. The S bit is set if the frame resulted from a CALLS instruction; it is clear if it resulted from a CALLG instruction.

SHOW CLUSTER

Displays connection manager and system communications services (SCS) information for all nodes in a cluster.

Format

SHOW CLUSTER {/CSID=csid|/NODE=name|/SCS}


Parameters

None.

Qualifiers

/CSID=csid

Displays VAXcluster system information for a specific VAXcluster member node. The value csid is the cluster system identification number (CSID) of the node to be displayed.7

/NODE=name

Displays VAXcluster system information for a specific VAXcluster member node. The value name is the name of the node to be displayed.

/SCS

Displays a view of the cluster as seen by SCS.

Description

By default, the SHOW CLUSTER command provides a view of the VAXcluster system from the perspective of the connection manager. When you use the /SCS qualifier, however, SHOW CLUSTER provides a view of the cluster from the perspective of the port driver or drivers.

VAXcluster as Seen by the Connection Manager

The SHOW CLUSTER command provides a series of displays.

The VAXcluster summary display supplies the following information:

The CSB list displays information about the VAXcluster system blocks (CSB) currently in operation; there is one CSB assigned to each node of the cluster. For each CSB, the CSB list displays the following information:

The cluster block display includes information recorded in the cluster block (CLUB), including a list of activated flags, a summary of quorum and vote information, and other data that applies to the cluster from the perspective of the node for which SDA is being run.

The cluster failover control block display provides detailed information concerning the cluster failover control block (CLUFCB), and the cluster quorum disk control block display provides detailed information from the cluster quorum disk control block (CLUDCB).

Subsequent displays provide information for each CSB listed previously in the CSB list display. Each display shows the state and flags of a CSB, as well as other specific node information. (See the Show Cluster utility section of the OpenVMS System Management Utilities Reference Manual for information about the flags for VAXcluster nodes.)

VAXcluster as Seen by the Port Driver

The SHOW CLUSTER/SCS command provides a series of displays.

The SCS listening process directory lists those processes that are listening for incoming SCS connect requests. For each of these processes, this display records the following information:

The SCS systems summary display provides the system block (SB) address, node name, system type, system ID, and the number of connection paths for each SCS system. An SCS system can be a VAXcluster member, HSC, UDA, or other such device.

Subsequent displays provide detailed information for each of the system blocks and the associated path blocks. The system block displays include the maximum message and datagram sizes, local hardware and software data, and SCS poller information. Path block displays include information that describes the connection, including remote functions and other path-related data.

This example shows a subset of a typical output for the SHOW CLUSTER/SCS command. In this system, there are three nodes (DORIS, GUS, and SOLLY), and there are two HSCs (PINTO and DODGER). After the summary information in the first two screen displays, specific information for each system block and its associated path block is shown.

Note

7 You can find the CSID for a specific node in a cluster by examining the CSB list display of the SHOW CLUSTER command. Other SDA displays refer to a system's CSID. For instance, the SHOW LOCK command indicates where a lock is mastered or held by CSID.
8 For information about the state and status of nodes, see the description of the ADD command in the Show Cluster utility section of the OpenVMS System Management Utilities Reference Manual.
