How long does Oracle RAC cluster deployment take?

It depends on node count and environment complexity. A basic 2-node RAC takes about 2-3 days including OS preparation, Grid Infrastructure installation, ASM storage configuration, database creation and functional verification; multi-node or Data Guard configurations take longer. ZhongLianDa has Oracle OCE-certified engineers and has deployed hundreds of RAC clusters for finance and manufacturing customers, going live inside maintenance windows with data safety as a priority.
