When Active Parameters is selected in tree-view, the following table is displayed in detail-view:
Pools and Queues

Logging
Options
User Exits to be Used
Note:
A dropdown menu allos the user to alternate the display between the
current and the default parameters.
The meaning of ON/OFF options in the Logging section of the active parameters panel are explained in the following table:
| Parameter | Action |
|---|---|
| Log Adabas Control Block | Enable Adabas control block logging. |
| Log Format Buffer | Enable format buffer logging. |
| Log Record Buffer | Enable record buffer logging. |
| Log Search Buffer | Enable search buffer logging. |
| Log Value Buffer | Enable value buffer logging. |
| Log ISN Buffer | Enable ISN buffer logging. |
| Log I/O Activity | Enable I/O activity logging. |
| Log Buffer Description | Enable buffer description logging. |
| Command Log Layout | New CLOG Layout |
| Protection Log required | Indicates whether a protection log is required for this session (the default is ). |
The meaning of ON/OFF options in the Options section of the active parameters panel are explained in the following table:
| Parameter | Action |
|---|---|
| Truncation | Enable truncation of alphanumeric field values. |
| Utilities Only | If this is enabled, all non-utility calls are rejected and the DBA has exclusive control over all database files. |
| Local Utilities | If Local Utilities is
enabled, remote utilities cannot be executed.
|
| Open Required | If Open Required is
enabled, an open (OP) command must be issued as the first command of a user
session. This option should be set if lnk_set_adabas_id is used when calling
Adabas from application servers, and also when using Net-Work, otherwise in
these cases Adabas cannot guarantee transaction integrity following an ADANUC
restart.
|
| Fault Tolerant AR | When Fault Tolerant AR is
enabled, the nucleus behaviour in the event of an Adabas
error during autorestart can be controlled. If an error occurs
for a given file, a detailed entry is made in the nucleus log, but the
autorestart continues. When the autorestart completes, the DBA can restore and
regenerate the file by using ADABCK RESTORE and ADAREC REGENERATE for the
affected file. If however the error occurred for the index of a file, it is
sufficient to rebuild the file's index by using the REINVERT function of
ADAINV. If Fault Tolerant AR is not selected,
Adabas aborts an autorestart if an error is
detected, and this can cause the database to be in an inconsistent state.
Note: |
| Autorestart Only | The AUTORESTART_ONLY keyword shuts down the nucleus immediately after its startup sequence has completed. If an autorestart is pending, the autorestart will be performed. No user commands or utility calls will be accepted by the nucleus. |
| Read Only | The READONLY option causes ADANUC to run in read-only mode. Refer to the Adabas for Open Systems Administration documentation for more details. |
| XA | The keyword XA indicates that the server will support distributed transaction processing according to the X/Open XA specification. If the Adabas XA interface is to be used by an application, OPTION=XA must be used. See XA Support in the Adabas for Open Systems Administration documentation for further information. |
| Auto Expand | Enable auto expand when the database becomes full. You can specify reserved and temporary locations for database auto expand by right-clicking the database name and selecting in the dropdown menu. For detailed information see the Adabas Extended Operation documentation. |
| Write Before Image to PLOG | Enable Write Before Image to
PLOG.
|
| Behaviour on Conflict During AUTORESTART | If is enabled, the autorestart will continue even in case of a conflict (the default is ). |
For more information on the nucleus parameters see the Adabas Open Systems Utilities documentation.
