Unix Systems Administrator
European Central Bank Frankfurt
April 2004 November 2006
The ECB required an experienced Solaris administrator to perform second line support as wellas project tasks.
The range of skills required varied from knowledge of NIS+, Veritas Volume
Manger and Disksuite to supporting the many varied bespoke applications and webservers
used by the Statisticians and National Banks.
My primary tasks were to take care of any UNIX issues being raised by the first line supportteam,and to
facilitate any required hardware replacements. The range of systems comprised
of a full range of servers from E15K and Sun Cluster down to Ultra 2's running a combinationofSolaris 8 and 9
and Sun 5200 Storage Arrays.
I was required to use TSM ( Tivoli ) for network restores and backups,and to perform standardadmin tasks such
as password resets,printer setups,resetting NIS+ credentials and well asthe usualrole of monitoring disks and
filesystems, and arranging engineer site visits forhardware replacements.
I also installed Fortran compilers and liaised with the suppliers of anapplication called “Troll” when
troubleshooting problems encountered by the statisticians.
I also supported the Solaris system hosting a Sybase database systemused for Reuters feeds,which was housed
in the Bundesbank.
