View Descriptions

This section gives a detailed description of every view available through Entire System Server. The section is structured as follows:

  • The selection box below lists all view descriptions in alphabetical order. Each view description subsection gives a full description of the view, listing first all field names according to operating system. An overview of error messages relevant to the view is given, followed by a detailed description of each field in alphabetical order.

  • The subsection General Information  explains how the description of each view is organized, and describes global fields (that is, fields relevant to each view).

  • The subsection View Summary provides an overview of available views, listing them according to their functional area.

General Information

The description of each view in this section begins with a header subsection containing the following general information about the view:

Item Meaning
File   The file number assigned to the view within Entire System Server. This number must not be changed.
Opsys  Operating system(s) to which the view applies.
Statement  The statement you must use in your Natural programs to access the view. This is either FIND or PROCESS, depending on the view and the required function.
Task  A short description of the purpose of the view. This description is based on the online help text provided for each view in the online tutorial (see Online Tutorial).

Note:
The view name may be changed by the Entire System Server Administrator. The file number and access statement cannot be changed.

Example:

You will find this header subsection for the view ACTIVE-JOBS:

Item Meaning
File 29
Opsys  z/OS, z/VSE, BS2000
Statement  FIND
Task Retrieve the tasks that are currently active in the system and get information about them (for example, the amount of CPU time already used by the tasks).

BS2000: corresponds to BS2000 command /sta p: retrieve tasks of Type 2 or 3.

Each view description contains the following information for fields defined to the view:

Item Meaning
Dictionary Field Name The name of the field in Natural.
F/L  Field format and length:
A Alphanumeric
B Binary
D Date
N Numeric
T Time
Mu  For fields that can be specified more than once, this column gives the maximum number of occurrences.
DE  Descriptor.

D in this column means that this field name can be specified in the WITH clause of the FIND statement or the USING clause of the PROCESS statement. These fields support the search criteria available for the FIND statement (see Getting Started) where this is appropriate.

Remarks  General remarks concerning the field, for example, whether it is required, or whether it is dependent on a particular function.

Example:

The following table is the overview of some fields common to all operating systems for the view COPY-FILE:

Dictionary Field Name F/L Mu DE Remarks
Common Fields for all Operating Systems:
ERROR-CODE N3      
ERROR-TEXT A58      
NODE N3   D  
NODE-NAME A16   D  
SYSTEM-MESSAGE-CODE A10      
FROM-DSNAME A54   D Required
FROM-PRODUCT A1   D  
FROM-PASSWORD A32   D  
TO-DSNAME A54   D Required

Global Fields

Certain fields are common to all views. These are known as global fields and do not appear in the full description of each field in this section (though they are included in the field overview for each view). The global fields are:

Field Name Type/Length Operating System
ERROR-CODE (N3) z/OS, z/VSE, BS2000

Message code returned. For the meaning of message codes, see the Entire System Server Messages and Codes documentation.

Field Name Type/Length Operating System
ERROR-TEXT (A58) z/OS, z/VSE, BS2000

Message text. For the meaning of message, see the Entire System Server Messages and Codes documentation. .

Field Name Type/Length Operating System
NODE (N3) z/OS, z/VSE, BS2000

Number of the Entire System Server node to be addressed. Typically, the node number is required if you are working in a distributed environment and you wish to perform a function on a different computer in the network (see also Using the Entire System Server in the Entire System Server Installation and Customization documentation).

Field Name Type/Length Operating System
NODE-NAME (A16) z/OS, z/VSE, BS2000

Name of the Entire System Server node to be addressed. This field is optional. For further information, see Using Entire System Server in a Multi-Computer Environment in the section Getting Started.

Field Name Type/Length Operating System
SYSTEM-CODE (B2) BS2000

Original system error code.

Field Name Type/Length Operating System
SYSTEM-MESSAGE-CODE (A10) BS2000, z/OS, z/VSE

System error code specific to the operating system. A code returned in the ERROR-CODE field can translate to any of a number of operating-system-specific system codes.

If any call to Entire System Server gets an error code of 508 with the error text ESY5508 ADABAS response code :1: returned from ESY, then the field SYSTEM-MESSAGE-CODE is filled with the appropriate Adabas response code in the form ADAnnn, where nnn is the Adabas response code.

Global Error Codes

Certain error codes may be returned with any view. These are known as Global Error Codes. Each view description in this section contains a table with possible error codes relevant to the view. The table below contains a list of global error codes. A full explanation of error codes is given in the Entire System Server Messages and Codes documentation.

Code Text z/OS z/VSE BS2000
0 Request completed successfully X X X
507 Too many parallel ESY requests. X X X
508 Adabas response code xxx returned from ESY. X X X
510 Logon required. X X X
520 No core available (ASIZE). X X X
521 NATPNI/NATPNIP unresolved. X X X
530 Access denied by Security Facility.     X*
774 No core available. X X X
776 Request was cancelled. X X X
777 Request has abended. X X X
999 Entire System Server node nnn not active. X X X

*

Note:
In BS2000, if error code 799 (Entire System Server internal error) is returned, check the field SYSTEM-MESSAGE-CODE for additional information.

Order of Information returned by Views

Unless otherwise noted, the default return order of information returned by view processors accessed by FIND (but not FIND (1) for reading views) is not guaranteed to be in any specific order. The views that have a guarantee of default order are:

  • CONSOLE

  • CONSOLE-LOG

  • IDCAMS

  • IEBCOPY

  • LIB-DIRECTORY

  • LIB-ZAP

  • NET-OPER

  • READ-FILE

  • READ-SPOOL

  • SYSTEM-COMMAND

More information regarding a specific order of returned information can be found in the appropriate view description.

If information needs to be returned in a specific order, the Natural SORT statement can be used. See the Natural Statements manual for more information.

All views accessed by PROCESS or FIND (1) (update views) will deliver data in the order received by the program.
