Remote-Admin

Introduction

The administration of a CortexDB instance takes place via the so-called Remote-Admin. This allows the administration of basic database settings and provides corresponding functions. Among other things, this tool makes it possible to create the configuration from remote workstations (or directly at the server location itself), to set up users, to carry out updates or to carry out a manual backup and/or a restore.

After starting the Remote Admin, the login is done at the database to be managed. To do this, enter the server name (or IP address) followed by the database port.

For example:

    demoserver:29000

or:

    127.0.0.1:29001

The login will then be completed by entering the corresponding server password and confirmed with OK (or the Enter key).

After login, functions for further administration are available. These are called via the respective buttons:

General View

The Remote Admin window is divided into several sections:

In the upper white area, the current log entries are output. These are also written in the ctxserver.log file. Usually, the meaning of the messages listed here is very easy to read.

Version:3.0.14;todo:check and fix;Date:15.10.2016; Name:Screenshot.RemAdm.Anwend

The second text window shows the logged-in instances on this server. Usually, only the accesses via the remote admin and the php accesses are listed here. If a replication was started by another server, this access is also visible.

The graphic output in traffic light form displays the runtime status of the database server. As a rule, this traffic light should be on * green * - the database is running. In the case of maintenance tasks or errors, the traffic light will jump to yellow or red. Any errors can therefore be read in the log file (or in the log window).

Functions of the Remote-Admin

The administration of a CortexDB instance takes place via functions that can be accessed via individual buttons. If an administrator has the access data to a server, the administration can be carried out remotely (remote).

The functions shown here are explained below in detail:

Backup/Restore

The Backup and Restore functions perform a manual backup or restore a backup file.

When performing the backup, a query is created whether the backup should be created with or without serial number. A backup file with serial number can only be used with the corresponding license and can not be read on any other server with a different license. A backup without a license is generally readable and can therefore be restored to other servers.

Only after confirming the query will the corresponding backup file be created in the configured backup directory (see configuration in the ini file). Depending on the size of the database and the changes logged, it will take a few minutes to complete.

While a backup is being created, it is possible to continue working with the database. The backup contains only the database information that was available up to the moment the backup started. If additional data is recorded in the database during the backup creation, it will not be available until the next backup.

To restore a database, it is necessary that the appropriate backup file is available in the configured backup directory. When the Restore function is called, the respective file is selected, which is then read in immediately.

On restores all database contents and change information (if any) will be restored. If a backup file is imported without a license, it is necessary that the second license file (the so-called lic file) to be integrated after the restoration via the license button.

As a rule, the backup files have complete configurations and license entries, so that the database can be used immediately after the restoration.

Info

This feature displays the version information and the license information in a detail area. As a rule, this information can also be viewed directly via the server files (possibly also via user programs).

Field-Definition

The field definition allows fields to be configured, imported or exported to use the CortexUniplex application. Since this function has meanwhile been implemented in the CortexUniplex, the field maintenance should be omitted here.

Counter-Definition

During the use of the CortexUniplex by users, so-called counter fields can be used. These offer the possibility of using unique counter readings, for example to generate specific, unique values (for example ticket numbers, invoice numbers, ...). Within the = CortexUniplex configuration, these fields are therefore controlled separately. A response of the counters via the API or during the automatic import is not possible.

Variables are available for these fields in order to be able to reset the counters after a certain time or to supplement them with further information.

    %j    Jahr zweistellig, z.B. für '96'
    %J    Jahr vierstellig, z.B. für '1996'
    %m    Monat einstellig von 1-9,
          sowie A,B,C für Oktober, November, Dezember
    %M    Monat zweistellig, z.B. '06' für 'Juni'
    %z    Fortlaufende Nummer ohne autom. Rücksetzung
    %Z    Fortlaufende Nummer mit autom. Rücksetzung
          nach Ablauf eines Monats bzw. Jahres

For leading zeroes in the consecutive numbers, the number of digits behind can be specified. For example, it is possible to configure the following counter:

     %j%M%Z3 -> 1401001, 1401002, 1401003, ... , 1402001, ... 

The use of these meter fields is only possible in an interactive user environment. It is not possible to access and set the counters via API or other mechanisms.

License

To activate a new database or to extend functions, it is necessary to include the second part of the database license (the so-called lic file). This is possible via the license function of the remote admin. After selecting the appropriate license file, the integration is acknowledged accordingly.

If the lic file does not match the stored par file in the server directory, a corresponding error message is output and logged in the log file of the server (error code-1010, DSV_LICENSE_ERROR).

CHH-Init

The database server logs all changes in the so-called change history (chh). This change history is also kept in the backup files and is also available after a restore. If the change information is irrelevant and the backup file is to be reduced, this history can be completely emptied with a chh-init.

PHP-Projects

These projects are functional extensions that are stored inside the server. For example, the application CortexUniplex is a plugin within the server. Other functions (including extensions for the CortexUniplex) can be integrated here as well. So it is also possible to create your own extensions to use individual programs or program functions.

As a rule, the entry for each extension is one application identifier required within the license (lic file). So every extension can be individually and securely unlocked and licensed separately. The corresponding rights must then be set for the user accounts.

The file format is so-called xjz files. These may include, for example, html, php, JavaScript, image files and other formats.

User

The user administration allows the definition of application rights for selected users and password assignment.

NOTE

To change the default password for the administrative user of the remote admin, change the password for the user "root" (Id: 1).

Please note that the Password and Web password fields can be set for each user. The web password refers to all applications that are executed with the help of a browser (usually all extensions that use IP port 80). The password is for all native applications and should still be set on default per user to minimize potential security vulnerabilities.

Version:3.0.14;todo:check and fix;Date:15.10.2016; Name:Screenshot.RemAdm.UserVerw

The Web Admin privilege defines a user account as an administrator within the CortexUniplex application. Thus is the access to the administrative area possible.

If a user is to be granted usage rights for an application and this application is licensed, the corresponding option is available in the Options/Applications area. The different application names indicating the used and available licenses are listed there and can be activated/deactivated.

minimum necessary user

To be able to use the tools of the CortexPlatform completely, the user php with any password is necessary. This user owns the application php.

Report-Definition

The reporter is a database function that can be used to determine specific key figures for a dataset via direct references. For example, the sum of all invoice items could be aggregated into a billing record. Using definable filters, the operations sum, minimum, maximum, average and number can be determined and written into a dataset.

Note that the target fields are a separate field type (so-called Reporter Fields), which must be defined separately (via the field management). These fields, like all other fields, are also available for further evaluations and selections.

Reorganization

The database server transforms every scanned and changed dataset into its individual components (fields and contents) and writes them into the database index. Each content is therefore available for quick selection. For the ongoing changes during operation, the server maintains a temporary, dynamic working index, which, in contrast to the fixed database index, is constantly organized.

Therefore, many changes over a longer period of time can lead to considerable speed advantages if the dynamic index is transferred into the fixed index using the reorganization and thus will be reduced in size. Similarly, a reorganization is once necessary if a data import was initially performed via import mode and the database index must be established for the first time.

Report-Reorg.

Because the reporter fields are managed separately, they must be included in the database index. When changing the reporter rules, reorganize the reporter accordingly. Only then will the rules be executed correctly.

Start, Stop, Exit

The database server can be started and stopped via Start and Stop. The displayed traffic light then jumps to the corresponding color.

Leave the remote admin using Exit.
