    HF15-57-107Chronos 4.12 simplifies the work of administrators and users through new functions. Modules CronSender and AppStateR available as license extensions.


    The latest Version 4.12 of Chronos, the standard software for database archiving, is now available. The solution developed by CSP GmbH & Co. KG makes the archiving process and cooperation with linked applications even easier now. The features facilitating the support of database archiving and the search function for users have been further expanded. For example, searching was stabilised, search grammar extended and the performance of index handling was enhanced. In addition, two helpful functions are available through license extensions from Version 4.12: The CronSender module and the new AppStateR. Altogether, the database archiving software Chronos is an important Compliance element in handling data and thereby complements document archiving with additional contents subject to retention such as measuring and production data. The user companies can enjoy legal safety through the archived information while being able to monitor the growth of their databases and lowering costs.


    CronSender now allows starting various jobs externally in the new Chronos version. Export and import processes, update/delete jobs, local-index jobs and storage-jobs are triggered here by external tools. Under Linux or Unix selection is made via the Crontab. If Windows is used, the functions mentioned can be selected via the task manager. The external tool sends a return code back as soon as a process is finished. Chronos thus receives a status about the respective job and is then able to supply it to the administrator or user.


    The new AppStateR (the name stands for Application State Returner) is a framework used to read the status of applications. To this end, the AppStateR monitor monitors the linked Chronos servers in an individually configurable cycle. In the course of this monitoring process a status page is accessed via HTTP provided by the respective Chronos server. The application assesses the status data thus received. The result is written to a log file. This file can be analysed by the customer, either manually through a system administrator or also automatically by a corresponding monitoring tool. The data listed shows whether a check was successful or whether an error is possibly present. In addition, there are different levels according to the severity of the error. Finally, the log file also provides information as to whether the status message itself was correct or faulty. In the event of faulty status checks information on the cause is provided. Adaptations of the values to be checked and reported as well as output by the AppStateR are individually possible for any customer requirement.


    “With the new features in Chronos we ensure simple and convenient control from linked existing applications of external tools as well as the necessary monitoring of the jobs triggered. This makes the work of many administrators easier” emphasises product manager, Korbinian Hermann.
