## ACCOUNT-NATSUB

Operating System | Type | Default | Maximum Value Length
--- | --- | --- | ---
BS2000 | Optional | There is no default. | 8 bytes

The `ACCOUNT-NATSUB` value specifies an account number used for all Natural subtasks running under control of the Entire System Server. Do not specify any user information in startup parameter `PRMNATSUB`, if `ACCOUNT-NATSUB` is supplied.

## ADA5SVC

Operating System | Type | Default
--- | --- | ---
z/OS, z/VSE | Required. | None

The Adabas SVC number to be used. The Adabas SVC is used to perform various internal functions, including communication between the Natural program and the Entire System Server nucleus in multi-user mode.

Note
This parameter is also valid for all Adabas versions.

## APPC-LUNAME

Operating System | Type | Default | Maximum Value Length
--- | --- | --- | ---
z/OS | Optional | `NPRLU01` | 8 bytes

The name of the APPC/MVS LU to be used for the transaction program invoked by the `SYSTEM-COMMAND` view processor to execute TSO/E commands.

## APPC-MODENAME

Operating System | Type | Default | Maximum Value Length
--- | --- | --- | ---
z/OS | Optional | `APPCHOST` | 8 bytes

The name of the default logon mode name to be used with the APPC/MVS transaction program invoked by the `SYSTEM-COMMAND` view processor to execute TSO/E commands.

## APPC-TPNAME

Operating System | Type | Default | Maximum Value Length
--- | --- | --- | ---
z/OS | Optional | `SAG.NPRvrs.XCOMTP46` | 64 bytes

The name of the APPC/MVS transaction program to be invoked by the `SYSTEM-COMMAND` view processor to execute TSO/E commands.

## AUTOLOG

Operating System | Type | Default
--- | --- | ---
z/OS, z/VSE, BS2000 | Optional | `YES`

Specifies automatic logon to the Entire System Server at the start of the Natural session. Possible options:

Option | Explanation
--- | ---
`YES` | No password check is done as part of the Entire System Server logon, as long as the specified user ID matches the internal Natural user ID. An implicit logon is performed if the first user request is not a logon call.
`NO` | No logon to the Entire System Server is performed at the start of the Natural session, but note that if an external security system is installed, a logon to the Entire System Server including user ID and password is always required.

The usage of the `AUTOLOG` parameter depends on the network environment. If there is no Net-Work installed, the autolog feature should be used to avoid additional logon procedures if the password check has already been done as part of the TP or Natural logon.

In a Net-Work environment, the usage of `AUTOLOG` depends on the defined Net-Work nodes. If only mainframes are connected, we recommend using the autolog feature. In environments with PCs connected to Net-Work, Entire System Server should run without autolog (`AUTOLOG=NO`).

## CDATALEN

Operating System | Type | Default
--- | --- | ---
z/OS, z/VSE, BS2000 | Optional | `0`

The maximum size (in K bytes) of the common data pool. A value greater than 0 must be specified if the view `COMMON-DATA` is to be used.

## COMPLETE

Operating System | Type | Default
--- | --- | ---
z/OS, z/VSE | Optional | `NO`

Specifies whether Com-plete is installed on the system.

## CONACCESS

Operating System | Type | Default
--- | --- | ---
BS2000 | Optional | `NONE`

Specifies the access capability of the Entire System Server node to the Console Task. Possible options:

Option | Explanation
--- | ---
`NONE` | Default. Console Task will not be activated. The view `CONSOLE` can, therefore, only be used for the functions WTO and WTOR.
`READ` | Console Task will be activated if the parameter `JOBCONS` is specified. All retrieval functions of the view `CONSOLE` can be used.
`WRITE` | Same as for `READ` option, but operator commands can also be issued by using the view `CONSOLE`.

Write access can be restricted to certain users and commands, using the exit `USERCSEC`. For more information, see BS2000 Security Considerations in the Section BS2000 Considerations of the Entire System Server Administration documentation.

## CONSNAME

Operating System | Type | Default
--- | --- | ---
z/OS, z/VSE | Optional | is the string `ESYnnnnn`, where `nnnnn` is the node number of this Entire System Server.

This parameter indicates the name for your logical console in an MCS environment. If you have 2 different Entire System Servers running on the same SYSPLEX system with the same node number, you may choose your own name for your console in this case.

--- | --- | ---
z/OS, z/VSE | Optional | 1000 messages.

`nnn` is the number of messages to be kept. This parameter has been valid since MVS/ESA 5.1. and z/VSE 2.1. A wraparound table for z/OS or z/VSE console messages is generated. The number of slots for this table can be defined here.

`CONSTAB=0` will switch off the reading of console messages which is done in the background.

## DEFNATSEC

Operating System | Type | Default
--- | --- | ---
z/OS | Optional | ADDRSP

This parameter controls if a Natural subtask for an Entire System Management (ESM) product is to run in the security environment of the Entire System Server’s address space or in a separate subtask security environment with a RACF protected user ID.

Option | Explanation
--- | ---
`ADDRSP` | Natural subtasks are run in the security environment of the address space.
`TASK` | Natural subtasks are run in the security environment of the task with the user ID specified in the `DEFNATUSER` startup parameter. This user ID must be defined in RACF as a protected user ID.

## DEFNATUSER

Operating System | Type | Default
--- | --- | ---
z/OS | Optional | None

This parameter indicates a default z/OS Natural user which can be used to run Natural in Entire System Server's address space (for example: NCL, NOM, NOP).

## DYNAMPOOL

Operating System | Type | Default
--- | --- | ---
z/VSE | Optional | None

This parameter indicates the name of the CA-Dynam/D 'virtual' volume.

The `DYNAM` pool name is supported in `READ-FILE`, `WRITE-FILE` and `LIB-DIRECTORY` for referencing single volume data sets and libraries. It is not currently supported for `FILE-ALLOCATE`.

## EDIT-TIMEOUT

Operating System | Type | Default
--- | --- | ---

An `EDIT` session using Natural ISPF will stay active `nnn` minutes for Entire System Server, until it erases all resources for this user. You should adjust this value to timeout values for your TP system (Com-plete, CICS, TSO, etc.).

## EOR-JOBNAME-WITH-NODE

Operating System | Type | Default
--- | --- | ---
BS2000 | Optional | `NO`

This parameter allows you to manipulate the composition of job names for Entire Operations tasks managed as NATURAL-SUB-TASKS. If multiple Entire Operations monitors are running on the same machine, you may define this parameter value to `YES`. However, please consult Software AG support staff before adding or changing this parameter. Possible options:

Option | Explanation
--- | ---
`YES` | The `NODE` parameter value is used to replace the rightmost three bytes of the EOR job names. If the value of `NODE` is greater than 999, the rightmost five bytes of the job names are used for the `NODE` value.
`NO` | The job names supplied by EOR are used without any modification.

`NONE` | No userID is authorized.

## SYSTEMCONS

Operating System | Type | Default
--- | --- | ---
z/OS | Optional | `NONE`

This parameter indicates the system names where Entire System Server should collect console messages (for example, `SYSTEMCONS=DAEF`, `DA2F`, `ABCD`). In this case, we collect console messages from the 3 systems indicated.

The default value `NONE` means that no z/OS System limitation has been provided.

In other words, if you are running in a Sysplex environment, Entire System Server will read all messages from all z/OS consoles defined in the Sysplex. This may lead to an unwanted CPU power consumption if other products are producing much output on the related consoles.

Therefore we recommend to carefully check which console messages your programs want to see by using view `CONSOLE`. and to set this parameter to the system ID of your locals z/OS, if you only want to read the console messages from your local z/OS.

Note for z/VSE:

- The parameter `TCP-STACK` is supported at version 4.2 or above. It is ignored in earlier versions.

- The parameter must contain the ID of the corresponding stack, that is you need to set `TCP-STACK = SOCKETnn`, where nn is the ID of the VSE TCP stack.
