Dear colleagues,
On Tuesday, 15.10.2024, maintenance work will be carried out on the Oracle infrastructures.
There are several clusters under maintenance, so it is difficult to give an exact schedule, but the work on the IT-RAC should be completed by late noon.
We will inform the users of the IT-RAC separately about the completion of the work.

In general, the DB services are available and should be accessible.
However, there will always be session interruptions as the database services have to be swivelled.

This means that for most applications that work request-orientated, such as
web servers etc., or where session pools are used, such as Apex applications, there will be hardly any impairment.

There is a residual risk of transactions being cancelled, so attention should be paid to ensuring that data has actually been saved or, even better, that access is read-only.

Affected by the maintenance work are ALL
databases/database services/database clusters.

ALL database services and thus also the applications running on them are affected!
For example:
. BPM (GO)
. DESY (EASY, dosimetry, DOOR, vehicle pool, KDS, FORMS, contract management, Zeuha and many more. - f. APEX applications see:
https://it.desy.de/dienste/uco/aktuelles/liste_apex_anwendungen_auf_desy_db/index_ger.html)
. GIS
. IAM (IAM, annual meetings, risk management)
. Registry
. DMS (document management system)
. TeamCenter

The maintenance work was communicated in September and October CUC.
We will inform you as soon as the work has been completed.
If you have any questions, please contact Oracle Service directly by e-mail (oracle.service@desy.de).

Best regards,
DESY Oracle Service

PS: The maintenance can be viewed at https://it-news.desy.de/.

Maintenance caused by: Maintenance work on the infrastructure

Since the last update of the Cisco Secure Client for vpn.desy.de <http://vpn.desy.de/> on 7.3.2025, the behaviour of the software has changed.

It can happen that the previously pre-filled “vpn.desy.de <http://vpn.desy.de/>” disappears in the login window of the program. Previously, the Cisco VPN software “remembered” the settings. Since the update to more recent versions, vpn.desy.de <http://vpn.desy.de/> sometimes has to be entered again.

On Monday, 06.01.2025, the name resolution on central Linux installations will be changed to Anycast DNS. Anycast DNS increases the availability and reliablity of name resolutions on Linux.

After the change, only a single DNS server (dns.desy.de - 10.0.0.20) will be configured in /etc/resolv.conf. Additionally, the DHCP templates bios_Linux & uefi_Linux will be changed to Anycast DNS as well.

This change has been announced in the Computer User Committee (CUC).

By the end of the year, the DESY data center and the UCO will be staffed:

- Mon., 23.12.
- Fri., 27.12.
- Mon., 30.12.

Each day from 9:00h; Mon. until 17:00h / Fri. until 15:00h

On the following days the DESY computer center as well as the UCO won't be staffed and thus only the IT on-call service will be reachable on the following days:

- Tue., 24.12. - Thu., 26.12.
- Sat., 28.12. + Sun., 29.12. (Weekend)
- Tue., 31.12. + Wed., 01.01.

From Thursday, 02.01.2025, we will be available again as usual:
https://it.desy.de/help_uco

The acceptance of goods during opening hours and the continuous supervision of critical services are guaranteed. The telephone numbers of the IT on-call service are known to the experiment and machine control rooms as well as the technical emergency service.

On Tuesday, 14.01.2025, the additional protection of e-mail/calendar programs required for security reasons will become mandatory.

In order to be able to continue working with Outlook, Thunderbird or smartphone apps after 14.01.2025, please proceed as described in the following instructions already now:

https://it.desy.de/services/mfa/e_mail_programs/setting_up_an_apptoken

As agreed in the CUC, as of Tuesday, 03.12.2024 access from extern to the Wiki service XWiki (https://xwiki.desy.de) will only be possible via VPN or SSH.
A solution for worldwide read access without login for Spaces which have to be activated explicitly for this kind of access, is currently being developed.

The reason for this measure is to increase the security level of the information provided in XWiki.

If you have any questions, please contact the IT helpdesk at any time (uco@desy.de, Tel: 5005).

The DFN-Verein will severely restrict the GEANT TCS certificate service which is offered via the service provider Sectigo. Sectigo has unilaterally terminated the service as of 10.1.2025.

This means that it will no longer be possible to issue new server and user certificates from this date at the latest. This also applies to IGTF certificates in the grid computing environment. GEANT and DFN are working on providing the service via a new provider as quickly as possible.

Time scales are not yet known here, as soon as
information is available we will let you know.

If you are using server or user certificates from the above-mentioned certificate service yourself we strongly recommend that you renew the certificates that are due to expire in the next few months now.

Information on how to deal with server and user certificates can be found at.

Access to commercial channels and software repositories of Anaconda Inc. has been blocked DESY-wide with immediate effect.

Anaconda Inc. meanwhile considers research institutions like DESY as commercial users, for which corresponding usage fees apply. To prevent accidental use of non-free services it has been decided to block access to the Anaconda Inc. repositories (repo.anaconda.com) from the DESY network with immediate effect.

Existing conda environments and the Windows DSM installations will not be affected. Access to conda-forge and all other free channels hosted on anaconda.org will still be possible. Only the access to the non-free anaconda channels and download of the Anaconda Inc. provided installers (anaconda, miniconda) will not be possible anymore. We recommend to use miniforge (https://github.com/conda-forge/miniforge) instead.

Please get in touch with UCO (uco@desy.de) in the very unlikely case of problems due to the blocking of the commercial anaconda channels.
