Technical Consultant
- On Customer Unilever I was part on a large transition of their global MTS systems (Ecache,
Calido) from old Tru64 server to brand new HP Superdomes running HP-UX. All servers
were located in US and UK sites accessed remotely in Brazil, and I had to interact with the
local teams to check the physical part of the installation (mostly checking cabling) and
remotely configuring the kernel, filesystems and the high availability. Tests were conducted to
ensure the redundancy and high availability were working perfect.
- I have implemented an MC/Serviceguard cluster in a RHEL6 for Telefonica’s SAP system,
running full failure tests to ensure reliability
- Customer Vivo needed 150 Linux servers in 5 different configurations. Use of Kicstart files
reduced install from 3 weeks to 5 days.
- Worked on the logical move of the main SAP systems of customer Companhia Vale do Rio
Doce (a huge multinational Brazilian mining company) from Brazil to servers on a Canadian
site – 30 servers contained in 12 HP Superdomes, all being mission critical and with
MC/Serviceguard clusters. An international team split between Brazil and Canada, worked
with me helping to configure the servers and conduct high availability tests that made a quick
and tranquil transition in a single weekend.
- Worked on customer Claro’s physical move of 20 full-packed Superdomes containing over
50 servers (virtual and physical) from Rio de Janeiro to Campinas datacenter, the whole of
their mission critical servers, using bubble server strategy, and as Superdome modules were
freed on origin they were transferred to the destiny datacenter to the other Superdomes.
Besides configuration and tests, there were some module versions not compatible with some
Superdome complex versions, which demanded extra attention and some adjustments in the
migration waves, which in consequence occurred 100% on schedule and without incidents.
- I have implemented the new corporate servers (Superdomes) on customer MRS Logistica
with virtualization (vpars) and MC/Serviceguard high availability in 2 sites, following the best
redundancy, high availability and disaster recovery.
- Customer MRS HP-UX servers needed performance improvements. Analyzing their
environment I saw they would benefit from an OS upgrade, which was done in 2 waves (a
rolling upgrade) thanks to the high availability best pratices, without incidents and with a 40%
increase on disk performance, allowing all batches fit on the batch window.
- Customer NET (cable tv company) needed to install 48 servers, I have done it in one day
using virtual media resources of the blade servers.

2. -Customer Banco IBI had their virtual servers (vpars) reinitializing when customer issued an
ls –lR . I was called in a escalation and found an error on the virtualization configuration done
by the customer, corrected it and the problem was gone.
- Customer transitions escalated HP because of a simple tar command taking hours to
complete. I found an invalid entry on the nsswitch.conf file, corrected it and the problem was
gone.
- On a Consulting and Integration project on customer Vivo I was called to perform a server
migration on the TEMIP system. I have found out an opportunity to reform their high
availability configuration using the latest MC/Serviceguard version’s resources, such as
service hierarchy, on their packages and that helped solve long lasting problems and easing
the operation of the platform on scheduled or unscheduled outages.
- On customer Petrobras I implemented Serviceguard’s high availability in existing SAP
environments comprising 48 HP-UX virtual partitions (vpars). Because those SAP instances
were in use by the Dev team in Argentina I had to do it in 5 waves taking 2 weeks, working
around the clock on configuring and testing with the local SAP team, finishing it in record time
and delivering fail-proof systems.
- Customer Santher had performance problems. With help of a TOTVS specialist I made
adjustments on the HP-UX kernel, improving 150% the performance of their online and batch
transactions.
- On customer Santher I have found weakness on their high availability configuration,
applying the corrections allowed on the window and scheduling a new service including the
full analysis and correction along with other pending services.
- On customer Santher I have found long lasting problems caused by an old HP-UX version
bug. After I applied the patch the problem was gone.
