AE and BS2000

This topic provides an overview of how to use BS2000 on your AE system. It describes how you download, transport, and extract BS2000 files to your system. The BS2000 agent, which supports all file transfer functions, allows you to set specific attributes and you can use remote function calls. Examples show how you run BS2000 commands through Script objects.

Note: This integration capability, like all integrations of the Automic system, can support Service Orchestration Workflows. Such Workflows orchestrate automated processes that run across multiple platforms, domains, and applications to deliver a specific IT service. For more information, see About Service Orchestration.

Program BS2-TAR and BS2000 Text Archive (TAR file)

The downloads page provides BS2000 agent and BS2000 CallAPI files for download as a BS2000 text archive (TAR file). This text archive is a collection of BS2000 files that may include various file types such as SAM, ISAM, PAM, and PLAM. You use this text archive to transport the provided BS2000 files to your system. The program BS2-TAR then serves to extract them.

Download and Extract the Program BS2-TAR

BS2-TAR is available in IMAGE:TOOLS\BS2_TAR. This program extracts the text archive to your own user ID and is required for all transfers that are made with text archives.

Two options are available for using BS2-TAR:

BS2-TAR.BIN

This file contains the program BS2-TAR. This program has been transferred to the image folder using FTP in binary mode and you can re-transfer it to BS2000 using FTP as follows:

FTP

OPENBS2000 computer

user id (TSOS)

password

account

BIN

PUT BS2-TAR.BIN

BYE

In BS2000:

/CAT BS2-TAR.BIN,BS2-TAR,STATE=U,SHARE=YES,ACCESS=READ

BS2-TAR.TAR

This file includes the latest version of the program BS2-TAR in TAR format. To use it, BS2-TAR must already be installed on the BS2000 computer.

The file is transferred to BS2000 in text mode using any file transfer and extracted in BS2000 with BS2-TAR as follows:

/FILE BS2-TAR.TAR,LINK=TAR
/EXEC BS2-TAR

Use the Program BS2-TAR

The supplied TAR files whose names include NK4 are for NK4 pubsets. You can extract a TAR file with the following commands:

/FILEfrom file, LINK=TAR
/EXEC BS2-TAR

BS2000 Agent - File Transfer Support

The BS2000 agent supports all file transfer functions such as the transfers of text and binary files or file transfers with wildcard characters.

File Attributes for the File Transfer Destination

Specify file attributes for the destination in the File Transfer object properties. For more information, see File Transfers (JOBF). You can use all file attributes that comply with the file command. Enter them in the File Attributes field in the Destination Settings section of the File Transfer object. If you specify several file attributes, you need to separate them with commas. The following attributes are used by default:

Text mode

FCB=SAM,LINK=UCEXSAM,SPACE=(300,300)

Binary mode

SPACE=(300,300),BLKSIZE=STD,BLKCTRL=NO,FCB=PAM

Explicitly specified attributes replace default values or are added to the above command.

Important! You can use a file transfer to create ISAM files.

Example:

FCB=ISAM,BLKCTRL=DATA,RECFORM=V,KEYPOS=5,KEYLEN=8

Library Elements As Source and Destination

Elements of LMS libraries (PLAM) can be the source and the destination of a file transfer.

Library elements can be transferred between two LMS libraries.
A library element can be transferred to any destination system as a file.
Text files from any destination system can be transferred to an LMS library.

Use the following format to specify the element:

*LIB(Library,Element(Version),Type)

The element version is optional. If you do not define a version, the source file reads the highest version, or the target file writes version @.

Examples:

*LIB($RS.LMS.LIB,MY.ELEMENT,S)

*LIB($RS.LMS.LIB,MY.*,S)

Keeping the Original Attributes

To use the attributes of source files for the destination files, use the option Keep Original File Attributes in the Destination Settings of the File Transfer page. Source and destination platform must comply with each other.

Important! If you use this setting, you must not include additional attributes for the destination file as this will result in an error.

The following file attributes can be kept in BS2000 file transfers:

Attributes Catalog Macro
- ACCESS
- ACLPROT
- BASACL
- BACKUP
- CCS
- DESTROY
- EXDATE
- GROUPAR
- GUARDS
- LARGE
- OTHERAR
- OWNERAR
- RETPD
- SHARE
Attributes File Macro
- BLKCTRL
- BLKSIZE
- DUPEKY
- FCBTYPE
- KEYLEN
- KEYPOS
- RECFORM
- RECSIZE
- RETPD
- SPACE

Limitations to File Transfers with PAM Files

Important!

When the BS2000 agent sends the file: All the pages are read if the PAM file is available in Non-Key (NK) format without an end being marked.
When the BS2000 agent receives the file: When writing a PAM file, an end marker (an additional logical block) is attached. This block can occasionally destroy file structures.

Service Program for Remote Function Call (RFC) Tasks

The supplied files for the BS2000 agent include the service program UCYBRFC? for RFC tasks.

The INI file of the agent contains the section [RFC] with the parameter LOGON for the Agent BS2000. Here you can set the parameter 1 to have the user ID considered in the file transfer. In this case, the agent generates a batch job for this user ID. This batch job calls the service program UCYBRFC? which connects to TCP/IP using the port that has been defined in the [RFC] section with the parameter PORT. This connection enables the agent to verify the access rights of the specified user for the particular file.

Creating this batch job causes a performance loss for the agent. Therefore, the RFC tasks are kept available for further file transfers. The RFC task ends automatically after a specified timeframe (parameter TIMEOUT=) when it has not received queries anymore. When the agent ends, all the corresponding RFC tasks too.

Important! The file UCYBRFC? must be shareable when the RFC mechanism is activated.

Examples

BS2000 OS Command

Creating, forming, and processing a data sequence is a complex process where script functions and statements, and specific objects cooperate closely. The following example describes a BS2000 OS command that is executed from a Script object. The result is written to the script's activation report line by line.

Start the Script object SC.PROCESS.BS2000CMD with the following script:

:SET &HND# = PREP_PROCESS ('C70', 'BS2000CMD',,'CMD=/STA P','UC_LOGIN=Admin')

:PROCESS &HND#

: SET &LINE# = GET_PROCESS_LINE (&HND#)

: PRINT &LINE#

: ENDPROCESS

This script calls the function PREP_PROCESS which prepares the data sequence processing. The following parameters are assigned:

Host
The agent name where an event job is executed - in this case: C70.
EventJob
The job that should be executed - in this case EVENT.BS2000CMD.
Specifying BS2000CMD has the effect that the job EVENT.BS2000CMD starts.
Note: By default, client 0 includes the following event jobs in the PREP_PROCESS folder of the Process Assembly perspective: EVENT.BS2000CMD, EVENT.BS2000UCON, EVENT.UNIXCMD, EVENT.UNIXFS and EVENT.WINCMD. You can use them as they are or adjust them for your own event jobs.
Filter
This parameter is not used. Therefore, the default value "*" is used and all output lines from the console command are considered.
Action
The value /STA P is assigned to the script variable &CMD of the event job.
UC_LOGIN=
The event job executes this command by using the Login (LOGIN) ADMIN.

The job EVENT.BS2000CMD starts.

Important! In this job's Attributes page, activate the Display Attribute Dialog check box in the Runtime Parameters section. This action ensures the Include object ATTRDIA.BS2000 to be read. All attributes that are listed in the script of the Include object ATTRDIA.BS2000 can now be supplied with values. The Attribute Dialog is not displayed because the variable contents are passed on internally.

The job EVENT.BS2000CMD can now log in to run the console command.
- The scheduled command /STA P is stored in the script variable &CMD.
- SYSOUT is redirected to an output file and the command is executed.

The output file is transferred to the Automation Engine and is then available as a data sequence. The execution of the job EVENT.BS2000CMD is complete.

In the Script object SC.PROCESS.BS2000CMD, the script function PREP_PROCESS now returns a value. It refers to the administration data of the data sequence that should be processed.

This value is passed on to the script statement :PROCESS as a start parameter. :PROCESS and :ENDPROCESS form a processing loop which runs until the end of the data sequence is reached. During each iteration, a new line of this data sequence is read from the memory. By using the current value, the script function GET_PROCESS_LINE can retrieve the line content of the data sequence.

The script writes the current console line to the activation report.

BS2000 Console Command

Creating, forming, and processing a data sequence is a complex process where script functions and statements, and specific objects cooperate closely. The following example describes a BS2000 console command that is executed from a Script object. The result is written to the script's activation report line by line.

Important: To execute a BS2000 console command the UCYEBXXZ utility must be installed on the host. See Installing the Agent for BS2000.

Start the Script object SC.PROCESS.BS2000UCON with the following script:

:SET &HND# = PREP_PROCESS ('C70', 'BS2000UCON',,'CMD=BCDSIP DISP=O')
