Displays information about all resources in the system or about a resource associated with a specific lock.
SHOW RESOURCES [ /ADDRESS=n
| /ALL (d)
| /CONTENTION [=ALL][/FULL]
| /STATUS=(keyword[,...]) ]
/ADDRESS=nDisplays information from the resource block at the specified address.
/ALLDisplays information from all resource blocks (RSBs) in the system. This is the default behavior of the SHOW RESOURCES command.
/BRIEFDisplays a single line of information for each resource.
/CACHEDDisplays resource blocks that are no longer valid.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.) By default, a single line summary is displayed for each resource, followed by a single line summary for each lock on the resource. Use /FULL to obtain a detailed display for each resource that is in contention.
/FULLWhen used with /CONTENTION [=ALL], causes SDA to display details of each resource that is in contention instead of a single line summary.
/LISTDisplays summary information for each resource, followed by a list of all locks associated with the resource.
/LOCKID=lock-idDisplays information on the resource associated with the lock with the specified lock-id.
/NAME=nameDisplays information about the specific resource. Name may be the actual name of the resource, if it only contains uppercase letters, numerals, the underscore (_), dollar sign, colon (:), and some other printable characters, as for example, /NAME=MY_LOCK. If it contains other printable characters (including lowercase letters), you may need to enclose the name in quotation marks (""), as for example, /NAME="My_Lock/47". If it contains nonprintable characters, the name may be specified as a comma-separated list comprised of strings and hexadecimal numbers, as for example, /NAME=("My_Lock",0C00,"/47") would specify the name "My_Lock<NUL><FF>/47". The hexadecimal number can be no more than 8 digits (4 bytes) in length. Nonprintable sequences or more than 4 bytes must be split into multiple hexadecimal numbers. The maximum length of a resource name is 32 characters.
/OWNEDDisplays only owned resources.
/STATUS=(keyword[,...])Displays only resources that have the specified status bits set in the RSB$L_STATUS field. If you specify only one keyword, you can omit the parentheses. 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 directory entry 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_FORCE Forces tree move RM_FREEZE Freeze resource tree on this node RM_INTEREST Remaster due to master having no 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 sub-range requests in wait queue XVAL_VALID Indicates last value block was long block
The SHOW RESOURCES command displays the information listed in Table 4-26 either for each resource in the system or for the specific resource associated with the specified lock-id, address, or name.
Table 4-26 Resource Information in the SHOW RESOURCES Display Field (in order of display) Contents 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 4-27 shows the values and their meanings.
For information on conflicting and incompatible lock modes, see the HP 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 4-27. 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 4-27. 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 and ASCII dump of the first 16 bytes of the value block associated with this resource. See Extended Value Block later in this table for the display of the rest of the value block. Length Length in bytes of the resource name. x mode Processor mode of the namespace in which this RSB resides (Group, Kernel, User). 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. Extended Valblk If any of the last 48 bytes of the value block (see Valblk earlier in this table) are non-zero, then the entire 64-byte value block is displayed as hexadecimal and ASCII dumps. Otherwise this display is omitted. The display appears only when value block contents are non-zero, without regard to the state of the RSB$M_XVAL_VALID flag. 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.

These examples for Alpha and Integrity server systems show two cases:
- output from a program writing a longer block
- output where the last writer wrote a short value block (XVALID not set), but because a previous writer wrote non-zero data to the high portion of the block and these data are still present, the data in the Extended Value Block are shown.
This example of the SHOW RESOURCES/CONTENTION command shows all the resources for which there is contention, and which are to be included in deadlock searches.
This example shows the output from the SHOW RESOURCES/LIST command.
Displays information contained in the reserved memory descriptors. Reserved memory is used within the system by memory-resident global sections.
SHOW RMD [/qualifiers]
/ADDRESS=nDisplays a specific reserved memory descriptor entry, given its address.
/ALLDisplays information in all the reserved memory descriptors. This qualifier is the default.
The SHOW RMD command displays information that resides in the reserved memory descriptors. Table 4-28 shows the fields and their meanings.
Table 4-28 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
Gives the number of pages in use. If an error occurred 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 displays key flag bits by name. The names may use multiple lines in the display.

Displays the RMS data structures selected by the SET RMS command to be included in the default display of the SHOW PROCESS/RMS command.
The SHOW RMS command lists the names of the data structures selected for the default display of the SHOW PROCESS/RMS command.
For a description of the significance of the options listed in the SHOW RMS display, see the description of the SET RMS command and Table 4-3.
For an illustration of the information displayed by the SHOW PROCESS/RMS command, see the examples included in the description of the SHOW PROCESS command.
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.
The SHOW RMS command displays the full set of options available for display by the SHOW PROCESS/RMS command. SDA, by default, selects the full set of RMS options at the beginning of an analysis.
SDA> SET RMS=(IFAB=1,CCB,WCB) SDA> SHOW RMS RMS Display Options: IFB,CCB,WCB Display RMS structures only for IFI = 0001
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, about a specific SCS connection.
SHOW RSPID [/CONNECTION=cdt-address ]
/CONNECTION=cdt-addressDisplays 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:
SDA> SHOW RSPID --- Summary of Response Descriptor Table (RDT) 805E6F18 --- RSPID CDRP Address CDT Address Local Process Name Remote Node ----- ------------ ----------- ------------------ ----------- 39D00000 8062CC80 805E8710 VMS$VMScluster VANDQ1 EE210001 80637260 805E8C90 VMS$DISK_CL_DRVR ROMRDR EE240002 806382E0 805E8DF0 VMS$DISK_CL_DRVR VANDQ1 EE440003 806393E0 805E8F50 VMS$TAPE_CL_DRVR VANDQ1 5DB90004 80636BC0 805E8870 VMS$VMScluster ROMRDR 5C260005 80664040 805E8870 VMS$VMScluster ROMRDR 38F80006 80664A80 805E8710 VMS$VMScluster VANDQ1

Displays information about the shared memory common property partitions (CPPs). The default display shows a single-page summary that includes a single line for each CPP.
SHOW SHM_CPP [/qualifiers]
/ADDRESS=nDisplays a detailed page of information about an individual shared memory CPP given the address of the SHM_CPP structure.
/ALLDisplays a detailed page of information about each shared memory CPP.
/IDENT=nDisplays a detailed page of information about an individual shared memory CPP.
/PFN [=(option[,option,...])]Displays PFN data in addition to the basic SHM_CPP. The default is to display all lists (free, bad, untested), plus the PFN database pages and the complete range of PFNs in the CPP.
You can limit which lists are displayed by specifying one or more keywords from the following table. If you specify multiple keywords, enclose them in parentheses and separate keywords with a comma.
ALL_FRAGMENTS Displays the complete range of PFNs in the CPP. BAD Displays only the bad page list. FREE Displays only the free page list. PFNDB Displays the PFNs containing the PFN database. UNTESTED Displays only the untested page list.
If you specify /PFN without /ALL, /IDENT, or /ADDRESS, the system displays the PFN lists from the last shared memory CPP accessed.
