Entire Net-Work Operator Commands

This section describes the Entire Net-Work operator commands. It covers the following topics:


Overview

Although Entire Net-Work operates automatically, there are operator commands available to display or modify the status of the network and control the local Entire Net-Work node.

The Entire Net-Work commands described in this section are similar to Adabas operator commands. A summary and description of the operator commands for z/OS, BS2000/OSD are provided.

The Entire Net-WorkTCPX line driver has the ability to process operator commands that are directed to a specific link or directly to the driver. For more information about TCPX line driver operator commands, read TCPX Operator Commands.

Operator Command Descriptions

This section describes each of the operator commands in detail. The underlined portion of the command is the minimum abbreviation.

ADAEND, END, HALT, NETEND, STOP, and TERMINATE Commands

ADAEND 
END 
HALT 
NETEND 
STOP 
TERMINATE 

Any one of the above commands can be used to terminate an Entire Net-Work session normally. The STOP operator command (for example, STOP taskid or P taskid) can be used in z/OS environments.

A check is made for any additional parameters. If one is found, the command is rejected and message NET0115 is issued. Thus, erroneous commands are rejected and an accidental termination of Entire Net-Work is avoided.

Once the termination command has been accepted by Entire Net-Work, no more requests are selected from the request queue. Message NET0999 is displayed on the operator console confirming that normal termination procedures have been started.

Note:
The DUMP command also ends Entire Net-Work operation after performing a snap dump of pertinent data areas.

CLOSE Command

CLOSE driver

Terminate all activities of the driver by disconnecting and closing all links related to the driver, then closing the driver itself.

The effect of this command can be reversed by issuing the OPEN or START command for the driver, and CONNECT commands for the links (as appropriate).

CLOSE NETPRNT Command

CLOSE NETPRNT

Close the NETPRNT file and route all trace and snap output to the DDPRINT file. When the NETPRNT file is closed, the data set can be copied for sending to Software AG support, without shutting down Entire Net-Work. The file must be allocated SHR. This command cannot be abbreviated.

CONNECT Command

CONNECT linkname

Attempt to connect link linkname. The link name specified must match that used on the LINK statement. If the link was disconnected after a "handshaking" conflict, the CONNECT command can be used to retry the procedure. If the link is disabled, the CONNECT command can be used to enable it.

DEFINE Command

DEFINE   LINK   linkname={ link statement | LIKE linkname }

Define a link during Entire Net-Work operation. The link statement must adhere to the format described in the section about the related line driver.

Note:
DEFINE commands will only be accepted if the NODE statement DEFINE parameter is set to"Y" .

The LIKE linkname parameter can be used instead of the link statement to define a link by copying the parameters specified for a previously defined link. For example:

DEFINE LINK TOPSYS LIKE BOTSYS

Note:
DEFINE LINK, is permitted only if DEFINE=Y is specified on the NODE statement

DISABLE Command

DISABLE  linkname

Instructs the specified link not to accept any connections from other Entire Net-Work nodes. If the link is connected, it is disconnected and then disabled.

DISCONNECT Command

DISCONNECT linkname

Disconnect the specified link, which is connected to this node. The link name specified must be the same as that used on the LINK statement.

DISPLAY Command

DISPLAY  { ALINKS | CSCI | LINKS | LOGGING | NODES | PATHS | STATS | TARGETS | ZAPS } 
                  [ {name | string* } ]

Displays current information about the specified network component. Only one component type (link, node, path, logging, statistics, target, or zaps) can be specified in a single DISPLAY command. The information is displayed in the form of Entire Net-Work messages. For more information, see the section Messages and Codes.

The optional second parameter serves to qualify the display request, thereby limiting the information displayed. At the same time, additional information is displayed for qualified DISPLAY LINK or DISPLAY NODES requests.

The possible qualifier values and their meanings depend on the type of request. A link name, node name, or (numeric) target ID may be specified. Alternatively, a string ending in a "wild card" character (*) may be used to indicate all links or nodes whose names start with the specified string. The asterisk (* ) alone may be used to produce a display of all links or nodes, but additional information is shown only for qualified display requests.

DISPLAY CSCI Example

The following is an example of DISPLAY CSCI output:

F NETWK,D C
NETQ002I:  Csi Server  -ESG111- Act Targ(00039) Srv(00013)

NETQ002I:  Csi Server  KCOSRV4  Act Targ(01014) Srv(00007)
NETQ004I:  Registered Servers Display Function Complete

DISPLAY NODES Examples

The following is an example of DISPLAY NODES output:

F NETWK,D N
NET0122I: NODE FNODE     (50752) LOCAL
NET0122I: NODE ALSNODE   (54080) DIST 000040 VIA LINK LNKE

NET0122I: NODE ENODE     (50496) DIST 000020 VIA LINK LNKE

A qualifier is used in the following example:

F NETWK,D N A*
NET0122I: NODE ALSNODE   (54080) DIST 000040 VIA LINK LNKE
NET0123I: TARGETS: 00025 00171 00194 00175 00173 00018 00009
NET0123I: TARGETS: 00177
NET0122I: NODE ANODE     (49472) DIST 000020 VIA LINK LNKA
NET0123I: TARGETS: 00125 00192

NET0122I: NODE ENODE    (50496) DIST 000020 (001) VIA LINK LNKE

DISPLAY STATS Examples

The DISPLAY STATS command produces the same type of information found in the statistics displayed at the end of an Entire Net-Work session. A qualifier parameter, if given, would have no effect. The buffer usage statistics displayed depend on the operating system being used.

The following is an example of DISPLAY STATS output. It includes a NETB001I and a NETB009I for each active buffer pool, a set of NETB008I, NETB010I, and NETB012I for each subpool within the buffer pools, and a NETB013I for each operator command issued.

NET0124I: TARGET 00234 (I-N) ACTIVE ON NODE ANODE
NET0124I: TARGET 55769 (C-N) ACTIVE ON NODE ANODE

DISPLAY ZAPS Example

The DISPLAY ZAPS command lists, for each Entire Net-Work module, its name, assembly date, system maintenance level, and zap level. If zaps were applied after initial shipment, their numbers are listed as "Additional Zaps". The following is an excerpt from a DISPLAY ZAPS example:

F NETWK,D Z
NET0037I: NETCLF (1998/11/10 SM=0001) ZAP LEVEL 0000

DUMP Command

DUMP

Issue a snap dump, then end the Entire Net-Work session. DUMP is equivalent to the SNAP command followed by an ADAEND (or synonymous) command.

ENABLE Command

ENABLE  linkname

Revokes a previously entered DISABLE command. The specified link is instructed to accept incoming connect requests. Enabling a disconnected link does not connect the link.

FORCE Command

FORCE { nodename | nodeid }

Broadcasts a control message through the network to notify all Entire Net-Work nodes that the specified node is no longer available. This command is provided for diagnosis and exception handling, and should be used only on the advice of your Software AG technical support representative.

HELP Command

HELP

Lists the available Entire Net-Work operator commands with a short explanation of their function.

LOGDON Command

LOGDON TCPX

Activates logging for the Simple Connection Line Driver.

LOGDOFF Command

LOGDOFF TCPX

Deactivates logging for the Simple Connection Line Driver.

LOGLON Command

LOGLON {linkname[,linkname]... | (linkname[,linkname]...)  | ALL }

Activates logging for currently defined links that match the linknames specified in the command. The link names can be specified in parentheses or out of parentheses. At least one link name or "ALL" must be specified. If you specify "ALL", logging is activated for all links. You can use an asterisk (*) as a wildcard at the end of a link name ("linkname*") to specify a pattern of link names; logging will be activated for all currently defined links that match the pattern.

In the following example, logging is activated for links named XYZ and for links beginning with the characters "ABCD".

LOGLON XYZ, ACBD*

LOGLOFF Command

LOGLOFF {linkname[,linkname]... | (linkname[,linkname]...) | ALL }

Deactivates logging for currently defined links that match the linknames specified in the command. The link names can be specified in parentheses or out of parentheses. At least one link name or ALL must be specified. If you specify ALL, logging is deactivated for all links. You can use an asterisk (*) as a wildcard at the end of a link name ("linkname*") to specify a pattern of link names; logging will be deactivated for all currently defined links that match the pattern.

In the following example, logging is deactivated for links named XYZ and for links beginning with the characters "ABCD".

LOGLOFF (XYZ, ACBD*)

LOGTON Command

LOGTON {target-ID[,target-ID]... | (target-ID[,target-ID]...) }

Activates logging for the targets specified in the command. The target IDs can be specified in parentheses or out of parentheses. At least one target ID must be specified. Valid target ID values range from "1" through "65535".

In the following example, logging is activated for targets 12 and 181.

LOGTON 12, 181

LOGTOFF Command

LOGTOFF {target-ID[,target-ID]... | (target-ID[,target-ID]...) | ALL }

Deactivates logging for the targets specified in the command. The target IDs can be specified in parentheses or out of parentheses. At least one target ID or ALL must be specified. If you specify ALL, logging is deactivated for all targets. Valid target ID values range from "1" through "65535".

In the following example, logging is deactivated for targets 12 and 181.

LOGTOFF (12, 181)

OPEN Command

OPEN  driver

Reopen an installed/defined line driver that was stopped due to an access method or other network or system failure, or by the CLOSE operator command. The driver name must be the same as that specified on a DRIVER statement. Note that this command is currently a synonym for the START command. For further information, see the explanation of the START command.

OPEN NETPRNT Command

OPEN NETPRNT

Open the NETPRNT file and route all trace and snap output to NETPRNT. This command is necessary only after a CLOSE NETPRNT command has been used. It opens the NETPRNT file when Entire Net-Work is initialized. If the file is allocated SHR or OLD it will be erased when opened. This command cannot be abbreviated.

PROBE Command

PROBE  { nodename | nodeid } [ nnnn ]

The PROBE command verifies that the specified node is available and can be reached. Entire Net-Work issues internal probe commands for the same purpose during normal operation. PROBE routes an internal message to the specified node and back. If the node cannot be reached, this information is sent to all active nodes, updating the node status.

The optional second parameter specifies that nnnn bytes of random user data (64512 bytes maximum) are to be appended to the actual probe message. The exact length of the message sent can be calculated as follows:

70 + (nodestack size) + nnnn

where nodestack size is twice the number specified by the NODE statement parameter MAXPATH=, rounded up to the next multiple of 4. For example, with MAXPATH=4 (the default value) the following command results in a message of length 1078:

PROBE nodename 1000

The result of the operation is displayed on the operator console, as shown in the following example:

F NET1,PROBE TWO
NET0136I: PROBE MESSAGE SENT
NET0135I: PROBE FOR NODE TWO      (0001.711 SEC)
NET0120I: NODE TWO      (62194) DIST 000030 VIA LINK TOFIVE
NET0140I: VERSION v.r.s (1999/11/10)

RESUME Command

RESUME  linkname

Revokes a SUSPEND command for the specified link. The link's status changes to "active" and the link resumes sending queued messages.

SET Command

SET parameter=value, [ ... ]

The SET command can be used to change Entire Net-Work parameter settings dynamically without interrupting network operations. The SET command itself may be omitted.

Multiple parameters can be specified with one SET command. The parameters allowed for the SET command are a subset of those defined on the Entire Net-Work NODE statement. This section covers the following topics:

CQTIMER Parameter

SET CQTIMER=secs

The CQTIMER parameter of the SET command can be used to set the approximate waiting time allowed for a user or application to retrieve command results with a router-16-call before timeout occurs. For more information, read about the CQTIMER parameter of the NODE statement.

DUMP Parameter

SET DUMP={ ALL | NONE | BLOCKS | TRACETAB | BUFFERS | LINKAREA | FORMAT }

The DUMP parameter of the SET command can be used to set the storage areas to be included in a dump when Entire Net-Work terminates abnormally. The information is printed to the NETPRNT file if it is open. Otherwise, it is printed to the DDPRINT file. SET DUMP can be used to reduce the amount of output generated during an abend, especially on large Entire Net-Work systems. This command cannot be abbreviated.

In general, the default value of ALL should be used so that all diagnostic information is available to Software AG support.

Multiple values can be specified, separated by commas and surrounded by parentheses. For example:

SET DUMP=(BLOCKS, TRACETAB, FORMAT)

If conflicting values are specified, the last value specified is used. In the following, for example, the value used is NONE:

SET DUMP=(BLOCKS, TRACETAB, NONE)
Value Description
ALL All storage areas are dumped. This is the default value.
NONE No storage areas are dumped.
BLOCKS The major control blocks are dumped.
TRACETAB The internal trace table is dumped.
BUFFERS All internal buffer areas are dumped.
LINKAREA All storage areas related to a driver and link are dumped.
FORMAT The driver and link trace tables are formatted.

LOG Parameter

SET LOG={ ON | OFF | YES | NO | FULL | SHORT }

The LOG parameter of the SET command can be used to regulate control flow and logging of selected data areas to the printer data set. For more information, read about the LOG parameter of the NODE statement.

LOGBUF Parameter

SET LOGBUF={ ON | OFF | YES | NO}

The LOGBUF parameter of the SET command can be used to control the destination of log data. For more information, read about the LOGBUF parameter of the NODE statement.

LOGBUFSZ Parameter

SET LOGBUFSZ=[{0 | logbuffersize}]

The LOGBUFSZ parameter of the SET command can be used to specify the size of the log buffer. For more information, read about the LOGBUFSZ parameter of the NODE statement.

MAXPATH Parameter

SET  MAXPATH=linkcount

The MAXPATH parameter of the SET command can be used to set the maximum path link, specified in number of links, that a message from users on this node is expected to travel. For more information, read about the MAXPATH parameter of the NODE statement.

MSGFORM Parameter

SET  MSGFORM=message-format

The MSGFORM parameter of the SET command can be used to set the message format of console messages and DDPRINT output. For more information, read about the MSGFORM parameter of the NODE statement.

PASSWORD Parameter

SET  PASSWORD=password

The PASSWORD parameter of the SET command can be used to set the password that controls access to the Programmable Command Interface (PCI). For more information, read about the PASSWORD parameter of the NODE statement.

Note:
For security reasons, this command is accepted only through the Programmable Command Interface.

REMCMD Parameter

SET  REMCMD={ N | Y }

The REMCMD parameter of the SET command can be used to allow or disallow remote access to the Programmable Command Interface. For more information, read about the REMCMD parameter of the NODE statement.

REPLYTIM Parameter

SET  REPLYTIM=secs

The REPLYTIM parameter of the SET command can be used to set the time, in seconds, that this node is to wait for a reply to a user request before timing out. For more information, read about the REPLYTIM Parameter of the NODE statement.

SNAPERR Parameter

SET SNAPERR=[(msg1[,msg2][,msg3][,msg4]) | OFF]

Note:
The SET SNAPERR operator command does not work for all error messages. Use SNAPERR only under the direction of your Software AG support representative.

This optional parameter can be used for diagnostics. When specified correctly, it will take a snap dump whenever specific Entire Net-Work errors occur. For more information, read about the SNAPERR Parameter of the NODE statement.

To clear a SNAPERR setting, issue the operator command SET SNAPERR=OFF, or SET SNAPERR with no value specified.

TRACE, TROFF, and TRON Parameters

SET  { TRACE | TROFF | TRON }={ trace | (trace,...) }

The TRACE, TROFF, and TRON parameters of the SET command can be used to set the trace control parameters for performing program traces. For more information, read about the TRACE, TROFF, and TRON parameters of the NODE statement.

UCMSG Parameter

SET  UCMSG={ N | Y }

The UCMSG parameter of the SET command can be used to control whether messages are issued in upper case or mixed case. For more information, see the UCMSG parameter of the NODE statement.

ULINK Parameter

SET  ULINK={ N | Y }

The ULINK parameter of the SET command can be used to allow or disallow multiple links to an adjacent Entire Net-Work node. For more information, see the ULINK parameter of the NODE statement.

Examples

For example, the following operator command:

F NODEA,SET CQTIMER=180,TRACE=OFF

is equivalent to the following NODE statement specification:

NODEA,CQTIMER=180,TRACE=OFF

SNAP Command

SNAP  { BPH | CQ | CURRMSG |  LOGBUF | MAIN  | MYBLK |  TRACE |  UBQ } 

Issue a snap dump of selected data areas to the DDPRINT file and continue processing. (Under certain circumstances, a snap dump is performed internally at either normal or abnormal session end.)

The optional parameters are used to snap one or more specific data areas:

Parameter Area
BPH Buffer pool headers.
CQ Command queue.
CURRMSG Message that Entire Net-Work mainline is currently working on.
LOGBUF Log buffer.
MAIN Header of mainline module.
MYBLK Central control block.
TRACE Internal trace table.
UBQ UB-Queue (currently active Adabas commands).

START Command

START drivername

Restart an installed line driver that was stopped due to an access method or other network or system failure, or by the CLOSE operator command. The driver name must be the same as that specified on a DRIVER statement. The START command is a synonym for the OPEN command.

SUSPEND Command

SUSPEND linkname

Instructs the specified link to not send any more messages. However, Entire Net-Work can still queue messages on this link. The SUSPEND command is valid only if the link is active.

VERIFY Command

VERIFY target-id

The VERIFY command is used to verify whether a target is still active or present in the network.

This command will report on the status of the target. If the target is not active but still locally in the network, it is removed and will no longer be seen in the DISPLAY TARGETS command. If the target is active and on another node, the target, target attributes and node will be displayed. If the target is active locally, but is not known to Entire Net-Work, Entire Net-Work becomes aware of the target and broadcasts this information throughout the network.

Specify a valid numeric target-ID in the range from 1 to 65535 with this command.

Note:
This command potentially changes the status information within Entire Net-Work. You should therefore use it with care, and have a clear understanding of what's happening.

VERIFY command processing takes no action for virtual or relocatable targets managed by Adabas Cluster Services. It acts only on targets that are local to the Entire Net-Work node where the command is issued.

Examples

For example, the following command verifies whether target 181 is still in the network:

VERIFY 181 

When the target is active and local to the node, one of the following messages is issued:

NET0171I Verify target 00181 already active
NET0174I Verify target 00181 is relocatable or virtual

If the target is not present in the network, the following message is issued:

NET0172I Verify target 00181 not in this Net-Work

If the target is active and on another node, the following message is issued:

NET0124I: Target ttttt (a-a) active on node nnnnnnnn

where nnnnnnnn is the node name, ttttt is the target ID, and (a-a) are the attributes of the target.

If the target is locally active but is not known to Entire Net-Work, Entire Net-Work becomes aware of the target and issues the following broadcast message:

NET0042I  Local Target 000181 active
