This example shows information on the CPUs and memory for RAD 2.
Displays information about all resources in the system, or about a resource associated with a specific lock.
SHOW RESOURCES {/ADDRESS=n|/ALL (d)|
/BRIEF|/CACHED|/CONTENTION [=ALL]| /LOCKID=lock-id|/NAME=resource-name|
/OWNED|/STATUS=(keyword [keyword,])}
None.
/ADDRESS=n
Displays information from the resource block at the specified address./ALL
Displays information from all resource blocks (RSBs) in the system. This is the default behavior of the SHOW RESOURCES command./BRIEF
Displays a single line of information for each resource./CACHED
Displays resource blocks that are no longer valid. The memory for these resources is saved so that later requests for resources can use them./CONTENTION [=ALL]
Displays only resources that have at least one lock on either the waiting or conversion queue. Unless you specify the ALL keyword, resources with locks on the waiting or conversion queues that are not participating in deadlock searches are ignored. (Locks not participating in deadlock searches are requested with either the LCK$M_NODLCKWT or LCK$M_NODLCKBLK flags.)/LOCKID=lock-id
Displays information on the resource associated with the lock with the specified lock-id./NAME=resource-name
Displays information about a specific resource./OWNED
Causes SDA to display only owned resources./STATUS=(keyword [keyword,])
Displays only resources that have the specified status bits set in the RSB$L_STATUS field. Status keywords are as follows:
Keyword Meaning 2PC_IP Indicates a two-phase convert operation in progress BRL Indicates byte range resource CHK_BTR Checks for better master CVTFULRNG Indicates full-range requests in convert queue CVTSUBRNG Indicates sub-range requests in convert queue DIRENTRY Indicates entered in directory during failover DIR_IP Creates directory entry DIR_RQD Indicates directory entry required INVPEND Checks for value block invalidation RBLD_ACT Indicates lock rebuild active for this tree RBLD_IP Indicates rebuild operation in progress RBLD_RQD Indicates rebuild required for this resource tree RM_ACCEPT Accepts new master RM_DEFLECT Deflects remote interest RM_IP Indicates resource remaster in progress RM_PEND Indicates a pending resource remaster operation RM_RBLD Indicates to always rebuild resource tree RM_WAIT Blocks local activity VALCUR Indicates value block is current VALINVLD Indicates value block invalid WTFULRNG Indicates full-range requests in wait queue WTSUBRNG Indicates a full-range requests in wait queue
The SHOW RESOURCES command displays the information listed in Table 4-21 either for each resource in the system or for the specific resource associated with the specified lock-id, address or name.
Table 4-21 Resource Information in the SHOW RESOURCES Display Field Contents Address of RSB Address of the resource block (RSB) that describes this resource. GGMODE Indication of the most restrictive mode in which a lock on this resource has been granted. Table 4-22 shows the fields and values and their meanings. They are shown in order from the least restrictive mode to the most restrictive. For information on conflicting and incompatible lock modes, see the OpenVMS System Services Reference Manual.
Status The contents of the resource block status field. Parent RSB Address of the RSB that is the parent of this RSB. This field is 00000000 if the RSB itself is a parent block. CGMODE Indication of the most restrictive lock mode to which a lock on this resource is waiting to be converted. This does not include the mode for which the lock at the head of the conversion queue is waiting. See Table 4-22. Sub-RSB count Number of RSBs of which this RSB is the parent. This field is 0 if the RSB has no sub-RSBs. FGMODE Indication of the full-range grant mode. See Table 4-22. Lock Count The total count of all locks on the resource. RQSEQNM Sequence number of the request. BLKAST count Number of locks on this resource that have requested a blocking AST. CSID Cluster system identification number (CSID) and name of the node that owns the resource. Resource Dump of the name of this resource, as stored at the end of the RSB. The first two columns are the hexadecimal representation of the name, with the least significant byte represented by the rightmost two digits in the rightmost column. The third column contains the ASCII representation of the name, the least significant byte being represented by the leftmost character in the column. Periods in this column represent values that correspond to nonprinting ASCII characters. Valblk Hexadecimal dump of the 16-byte block value block associated with this resource. Length Length in bytes of the resource name. Mode Processor mode of the namespace in which this RSB resides. Owner Owner of the resource. Certain resources, owned by the operating system, list "System" as the owner. Locks owned by a group have the number (in octal) of the owning group in this field. Seqnum Sequence number associated with the resource's value block. If the number indicates that the value block is not valid, the words "Not valid" appear to the right of the number. Granted queue List of locks on this resource that have been granted. For each lock in the list, SDA displays the number of the lock and the lock mode in which the lock was granted. Conversion queue List of locks waiting to be converted from one mode to another. For each lock in the list, SDA displays the number of the lock, the mode in which the lock was granted, and the mode to which the lock is to be converted. Waiting queue List of locks waiting to be granted. For each lock in the list, SDA displays the number of the lock and the mode requested for that lock.

The SHOW RESOURCES command displays information taken from the RSBs of all resources in the system. For instance, the RSB at FFFFFFFF.7FA66A5016 is a parent block with no sub-RSBs.
This example of the SHOW RESOURCES/CONTENTION commands shows all the resources for which there is contention, and which are not to be included in dead lock searches.
Displays information contained in the reserved memory descriptors. Reserved memory is used within the system by memory-resident global sections.
SHOW RMD [/QUALIFIERS]
None.
/ADDRESS=n
Displays a specific reserved memory descriptor entry, given its address./ALL
Displays information in all the reserved memory descriptors. This qualifier is the default.
The SHOW RMD displays information that resides in the reserved memory descriptors. Table 4-23 shows the fields and their meaning.
Table 4-23 RMD Fields Field Meaning ADDRESS Gives the address of the reserved memory descriptor. NAME Gives the name of the reserved memory descriptor. GROUP Gives the UIC group that owns the reserved memory. This is given as -S- for system global reserved memory. RAD Gives the required RAD for the reserved memory. Displays "Any" if no RAD specified. PFN Gives starting page number of the reserved memory. COUNT Gives the number of pages reserved. IN_USE
/ERRORGives the number of pages in use. If an error occured when the reserved memory was being allocated, the error condition code is displayed in parentheses. A second line, giving the text of the error, is also displayed in this case. ZERO_PFN Gives the next page number to be zeroed. FLAGS Gives the settings of flags for specified reserved memory descriptor, as a hexadecimal number, then key flag bits are also displayed by name. The names may use multiple lines in the display.

The SET RMS command establishes the IFB, CCB, and WCB as the structures to be displayed, and only for the file whose internal File Identifer has the value 1, when the SHOW PROCESS/RMS command is issued. The SHOW RMS command verifies this selection of RMS options.
Displays information about response IDs (RSPIDs) of all System Communications Services (SCS) connections or, optionally, a specific SCS connection.
SHOW RSPID [/CONNECTION=cdt-address]
None.
/CONNECTION=cdt-address
Displays RSPID information for the specific SCS connection whose connection descriptor table (CDT) address is provided in cdt-address. You can find the cdt-address for any active connection on the system in the CDT summary page display of the SHOW CONNECTIONS command. CDT addresses are also stored in many individual data structures related to SCS connections. These data structures include class driver request packets (CDRPs) and unit control blocks (UCBs) for class drivers that use SCS and cluster system blocks (CSBs) for the connection manager.
Whenever a local system application (SYSAP) requires a response from a remote SYSAP, a unique number, called an RSPID, is assigned to the response by the local system. The RSPID is transmitted in the original request (as a means of identification), and the remote SYSAP returns the same RSPID in its response to the original request.The SHOW RSPID command displays information taken from the response descriptor table (RDT), which lists the currently open local requests that require responses from SYSAPs at a remote node. For each RSPID, SDA displays the following information:
