EntireX Broker provides the following internal services: Command Service and Information Service, which can be used to administer and monitor brokers. Because these services are implemented internally, nothing has to be started or configured. You can use these services immediately after starting EntireX Broker. This document covers the following topics:
Queries the Broker for different types of information, generating an
output text string with basic formatting. This text output can be further
processed by script languages. ETBINFO
uses data descriptions called profiles
to control the type of data that is returned for a request. ETBINFO
is useful
for monitoring and administering EntireX Broker efficiently, for example how
many users can run concurrently and whether the number of specified message
containers is large enough.
Although basic formatting of the output is available, it is usually formatted by script languages or other means external to the Broker.
In a BS2000 environment, run the command-line utility ETBINFO
as shown below:
/CALL-PROCEDURE (LIB=EXX103.JOBS,ELE=ETBINFO)
This executes the utility in BS2000 dialog mode.
The ETBINFO
parameters are supplied using an SDF variable, for
example:
/COMMAND = '-b&(BROKER-ID) -dBROKER'
See the delivered ETBINFO
job control in EXX103.JOBS.
The table below explains the command-line parameters. The format string and profile parameters are described in detail following the table. All entries in the Option column are case-sensitive.

If you do not use the profile option or a format string, your output will be an unformatted list with all columns of that display type. To display specific columns, specify a profile that includes only those columns.
The following default sample profiles include all the columns defined for each display type:
|
|
|
|
|
You can either delete the columns not required or copy the default profile and modify the order of the columns. Ensure that the column names have a leading "%". Column names can be written in one line or on separate lines. The output is always written side by side.
On BS2000, the profiles used to control the amount of data
displayed are contained in EXX103.JOBS and are called
PRO-BROKER
, PRO-CLIENT
etc.
Profile for object SERVICE: PRO-SERVICE.
To use a profile, the profile itself needs to be extracted from LMS
library EXX103.JOBS. Uncomment the LMS-section including SDF variable
COMMAND
in S-procedure ETBINFO
and adapt the
profile name. For example:
... / START-LMS // MOD-LMS-DEFAULTS MAX-ERROR-WEIGHT=*RECOVERABLE // EXTRACT-ELEMENT - // *LIB(LIB = &(EXX-JOBS), - // ELEM = PRO-SERVICE, - // TYPE = S), - // TO-FILE = #PROFILE, - // FILE-ATTR = (ACCESS-METHOD=*SAM), - // WRITE-MODE = *ANY //END /COMMAND = '-b&(BROKER-ID) -dSERVICE -p#PROFILE -lFULL' ...
See also the delivered ETBINFO
job control in EXX103.JOBS for more
details.
The format string, if specified, will override the use of a profile. The
format string is built like a printf()
in C language.
The string must be enclosed in quotation marks. You can specify the columns by
using a "%" and the column name. The column name must contain
letters only. Numeric characters are not allowed. You can specify the length of
column output by using a format precision, as in the ANSI-C
printf()
function. The column name must be followed by
a blank. For example:
/COMMAND = '-b&(BROKER-ID) -d BROKER -f "%12.12CPLATNAME %NUM-SERVER %NUM-CLIENT"'
which produces the following output, for example:
BS2000 W 30 100
You can also use an arbitrary column separator, which can be any
character other than "%". You can use \n
for a new
line in the output and \t
for a tabulator in the format string or
profile. For example:
/COMMAND = '-b&(BROKER-ID) -d SERVER -f "UserID: %5.5USER-ID Token: %5.5TOKEN"'
which produces:
UserID: HUGO Token: MYTOK UserID: EGON Token: UserID: HELMU Token: Helmu
If you want to structure your output a little more, you can operate with
the \n
or \t
character. For example:
/COMMAND = '-b&(BROKER-ID) -d SERVICE -f "Class:%5.5SERVER-CLASS \n\tName:%5.5SERVER-NAME \n\tService:%5.5SERVICE"
which produces:
Class:DATAB Name:DB10 Service:Admin Class:PRINT Name:LPT1 Service:PRINT ...
Allows the user to take actions - for example purge a unit of work, stop a server, shut down a Broker - against EntireX Broker.
In a BS2000 environment, run the ETBCMD
command-line utility like
this:
/CALL-PROCEDURE (LIB=EXX103.JOBS,ELE=ETBCMD)
This executes the utility in BS2000 dialog mode.
The ETBCMD parameters are supplied using an SDF variable. For example:
/COMMAND = '-b&(BROKER-ID) -dBROKER -cTRACE-ON -oLEVEL1'
See also delivered ETBCMD
job control in EXX103.JOBS.
