Issues for us (I)• Where is our server?
• Our restrictions: Server can be abroad, but it must be Europe; certainly not US.
• Ex Libris works with www.equinix.de (Computer/Data center worldwide, our installation in Amsterdam) ok fo

Issues for us (II)• circulation
performance
(distance to server 900 km instead of 20m or 1 km)
Till now we are happy with performance and connection! fo

Zentral- und Hochschulbibliothek Luzern
www.zhbluzern.ch homepage
Issues for us (III)• Cooperation too complicated? it works well (daily work like in the past)
• For example: GUI-Access only open for registered IP-Adresses? GUI-Access no restrictions (just restrictions you want to handle in server_ip_allowed) Restrictions only for SSH/SFTP (just registered IP-Adresses), which is reasonable

Zentral- und Hochschulbibliothek Luzern
www.zhbluzern.ch homepage
Issues for us (IV)• Loss of autonomy (some local programs/interfaces
not allowed/not possible??)
Until now, everything works fine, e.g.- Dirlist (Pearl) (Tool for web based access to parameter tables) - SAP-Interface (PL SQL)
(we do not have a lot of local specialities)

Zentral- und Hochschulbibliothek Luzern
www.zhbluzern.ch homepage
Issues for us (V)• Access rights?
Standard Aleph-User (aleph/oracle/sql) + sudo-rights where needed
aleph@dc03kg0257eu(a21_1) ILU01> sudo –lMatching Defaults entries for aleph on this host: !lecture, tty_tickets, !fqdnUser aleph may run the following commands on this host: (root) NOPASSWD: /exlibris/aleph/u21_1/alephe/apache/bin/
• Until now, we are ok with sudo rights – when we need more, we can talk to Exlibris fo

Issues for us (VI)• Exlibris to be stingy with Disk-Space?
Until now no problems, enough space for temporary needs

Issues for us (VII)• Can we work on the SQL-Level as we did the last 14 years? (f.ex.
Global updates in Z30)
Lucerne: Do we have the same rights to work on sql?Ex Libris: Select ok, Update forbidden (for all Aleph-Installations: local or hosted)
Lucerne: But we are used to update data on sql-level!Ex Libris: You will have same users/access-Rights in the hosted version as before, so you can work in the same way. fo

People concerned• Exlibris (Germany):
- 1 project manager- 1 technical consultant- 1 Implementation Consultant- ‘cloud team’
• Lucerne:- 1 project manager- 1 system librarian

who did what• Exlibris:
- Initial installation V21- Installation u-tree- [Initial export/import Oracle] by ourselves- Upgrade-Express (UPX) steps <1000 (parameters)
• Lucerne:- Adapting parameter tables- 2 x Export/Import of Oracle and UPX step > 1000 (oracle tables) - Service Pack 2 weeks prior to STP - Final Export/Import Oracle + UPX step > 1000 fo

Special problems• STP planned to be done by ourselves
(out of office hours!)Saturday 13.7.13 17:00 toSunday 14.7.13 17:00
• Starting with unexpected problem:imprudent killing a first launch of the Oracle-Export-script (it was not launched in the background) caused an Oracle Error and blocked the export needed Exlibris support 7x24hub in IsraelSupport was very very good, problem solved in the early morning

Communication during project
• In general good and uncomplicate• But could sometimes be improved:
- communication of some important parameters/informations took a long time- Some technical questions needed (too) many mails
• One explanation/reason: vacation period (june/july)

Backup
• Exlibris offers 7x24 service (no down time for Backup)
• We decided to have a shutdown/restart once a week

MonitoringThere are server level checks, that are not related to the product:1. Disk space2. CPU3. Load4. Ping There are app level checks:1. Search in the Aleph2. Oracle health checks3. J-Boss (For interoperability with Primo) In general, the checks are done every minute and create a critical alert if there is a sequence of 3 failed checks. But this can change, according to the level of false alerts we get and load on the monitoring system. If the customer wants to take down its Aleph, they need to let us know in advance so that we shut down the monitoring. Otherwise we will think that they are down and will try to restart their Aleph, which can ruin any work they are doing

Hello All –
IGELU-ELUNA-HOSTED-L is an unmoderated discussion list for users of Ex Libris’ Cloud Services. It is a way for users to share alerts and information specifically about that service, such as questions about connectivity or response problems. It’s an extremely low-traffic list. The only messages are generally the rare “Our catalog (or any other product) seems to be off line, is anyone else having that issue” posting. Discussions of specific Ex Libris products should be posted to the appropriate lists, such as Voyager-L or Aleph500-Discuss-L.
