Upgrades of Operational Linux Platforms Vito Baggiolini BE-CO-DO 1

Upgrades of Operational Consoles Console New Generation (a.k.a. “Console NG”) – Local home directories for operational accounts – bash shell (instead of tcsh) – Symbolic links to special places on NFS servers (e.g. ~/images) – Reason: less dependency on NFS, less cr*p in shared home dir, no tricks needed to handle shared home dir (JavaWS, Firefox, etc) Continue to replace Windows Operational Consoles by Linux – E.g. Cryo PVSS consoles Review Common Console Manager (CCM) – Review of functionality together with OP et al. – Better integration with the operating system (especially Linux) – Re-engineering and technology upgrade (e.g. JNI, shreg) 220-March-2013Vito Baggiolini

Upgrade of Operating Systems Operational Consoles: – Upgrade to SLC7/64bit (when it is ready, i.e. end 2013?) – Keep 32bit compatibility libraries only if needed for legacy apps Back-ends (Proliants): – Upgrade to pure SLC6/64bit, from Easter onwards Front-ends: – Two platforms: pure SLC5/32bit or pure SLC6/64bit – New kernel for SLC5 – Keep Kernels stable until LS2 (but ready to upgrade if absolutely needed) CO wants to move ahead with 64bit, currently validating – Go/no-go decision will be announced in April – End-of-life announcement: no 32bit support after LS2 320-March-2013Vito Baggiolini

Major CO TS after Easter (2-4 April) Change from Run to LS mode [DA] Change passwords of operational Oracle database accounts [DA] Adjust (possibly re-release) applications that access the databases, following the above change [DO] Change operator passwords [DO] Change operator accounts from tcsh to bash [DO] Upgrade Oracle client shared libs from Version 10 to 11 [DO] Upgrade Java from 1.6 to 1.7 [DO] Upgrade all non-PVSS servers from SLC5 to SLC6 [DO] Remove PVSS 3.6 from all the Consoles [IN] Upgrade firmware on all non-PVSS servers [IN] Upgrade and reboot all our NFS servers, restrict access lists [IT] Make Network changes (remove Class-B network, change default gateway) [IT] Replace 3com switches by HP [IT] Clean-up patch panels of big star points in 354, CCR/CCC, North Area “Note de coupure” will be sent out by Pierre soon 420-March-2013Vito Baggiolini
