Ignore DIB Entry Ignore and delete an existing data integrity block (DIB) entry in the Associator and initiate a new session.
Ignore Work Part 4 Ignore data related to the recovery of previously incomplete transactions that resides in the two-phase commit area (Work part 4) and start the nucleus anyway. For emergency use only: contact your Software AG technical support center before using.
LOCAL Nucleus Restrict a nucleus to local use only (no connection to other Entire Net-Work nodes).
Non-DE Search Restrict searches to descriptors only in search buffers (no searches on nondescriptors).
OPEN Required Require an OPEN command as the first command of a user session.
Read-Only Session Restrict a database session to reading data only (no updates allowed).
Ext. Error Recovery Enable extended error handling and message buffering.

Active Parameters for Open Systems Databases

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

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 On).

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:
The nucleus log can be displayed by right-clicking on the database name and choosing Nucleus Log in the dropdown menu.

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 Locations 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 Continue is enabled, the autorestart will continue even in case of a conflict (the default is Abort).

For more information on the nucleus parameters see the Adabas Open Systems Utilities documentation.
