Welcome to my profile.

I have thirty-one (31) years of experience in the field of information technology (IT), including twenty-five (26) years as an Oracle database administrator 8i, 9i, 10g, 11g 12c, 19c.

During the last 3 years, I participated in several large-scale projects which allowed me to develop a key skill for

the migration of critical databases to the version of Oracle RAC 19c,

which involved the following work:

• installation, according to best practices, of software (GI infrastructure (ASM and RAC-CLUSTER) and RDBMS),

• the quarterly update of security vulnerabilities,

• the optimal configuration,

• setting up backup and restoration procedures (RMAN) in the event of problems,

• the implementation of security procedures (UNIFIED AUDITING) to meet the expectations of external audits,

• infrastructure consolidation (MULTITENANT - CDB-PDB) to reduce licensing costs,

• high availability (DATAGUARD),

• monitoring (OEM - Enterprise Manager and Toad)

• and documentation.
