Quando a Oracle lan\u00e7a uma nova vers\u00e3o de banco de dados no mercado todos os profissionais da \u00e1rea ficam curiosos para conhecer as novas funcionalidades (features), e algumas delas proporcionam recursos fant\u00e1sticos para facilitar a vida de quem trabalha com isso, porem muitas vezes n\u00e3o fica claro que algumas dessas novas funcionalidades requerem uma licen\u00e7a adicional. Esse \u00e9 o caso do “Feature SQL Profile”, para utiliz\u00e1-la alem da licen\u00e7a do Oracle Database Enterprise Edition precisamos adquirir a “Option Tuning Pack<\/a><\/strong>” que por sua vez requer a “Option Diagnostic Pack<\/a><\/strong>“.<\/span><\/p>\n

A leitura do documento de licen\u00e7a da Oracle n\u00e3o \u00e9 muito clara quanto ao fato de que a “Feature SQL Profile” faz parte da “Option Tuning Pack”, para validar essa informa\u00e7\u00e3o vamos realizar uma simula\u00e7\u00e3o com uma consulta ativando e desativando a “Option Tuning Pack” para verificar se ela realmente faz parte dessa Option.<\/span><\/p>\n

Para aqueles que n\u00e3o disp\u00f5em das licen\u00e7as “Diagnostic and Tuning Pack” em sua base Oracle Enterprise Edition, uma alternativa \u00e9 a utiliza\u00e7\u00e3o da SQL Plan Management (SPM), cujos recursos s\u00e3o bem parecidos com SQL Profile. <\/p>\n

Simulando a utiliza\u00e7\u00e3o da SQL Profile<\/span><\/h2>\n

Para validar a necessidade da licen\u00e7a “Diagnostic and Tuning Pack” quando da\u00a0utiliza\u00e7\u00e3o da “Feature SQL Profile” vamos realizar o seguinte procedimento:<\/span><\/p>\n

 <\/p>\n

1)<\/strong> Vamos verificar se as “Options Diagnostic and Tuning Pack” est\u00e3o habilitadas consultando o valor do par\u00e2metro “control_management_pack_access”;<\/span><\/p>\n

2)<\/strong> Com as Options habilitadas vamos executar uma consulta que possui uma SQL Profile definida;<\/span><\/p>\n

3)<\/strong> Utilizando o pacote DBMS_XPLAN vamos exibir o plano de execu\u00e7\u00e3o e verificar se\u00e7\u00e3o “Note” se a SQL Profile esta sendo utilizada;<\/span><\/p>\n

Precisamos verificar quais s\u00e3o as options que possuem licen\u00e7a nas bases que estamos trabalhando pois podemos estar utilizando options que n\u00e3o foram adquiridas e isso pode causar problemas para a empresa numa auditoria de licen\u00e7as da Oracle.
