GG Build Source Single instance---to target RAC Environment 11.2.3 version one-way synchronization Purpose After completing this Oracle by Example (OBE) tutorial, you will be able to keep two heterogeneous databases synchronized using Oracle Goldengate (OGG), in which case the Linux Oracle 11GR2 database to the 11GR2 exadata database. In this lesson, you will learn how to: Prepare your environment to configure the Oracle goldengate process. Configu

Multi-table join query. the test process mainly targets QData and Oracle Exadata1/4 and 1/8 configurations of voqutech. Test conclusion: 1. QData completes all 17 tests; 2. When the hardware configuration of QData is significantly lower than that of Oracle Exadata 1/4 and 1/8, the performance index is significantly better than that of Oracle

lineorder INMEMORY Distribute by PARTITION; If the data should be stored in the memory area of redundancy, if it is a normal RAC database, then the data will not be in the memory area to save redundancy, and for the Exadata-in-memory area of the data can be set redundant. The reason why this is chosen is that the private network configuration of the non-Exadata integrated RAC system is very diverse, if you

Preface: Table Compression should be supported from 10 Gb. Oracle 11g exadata used this feature to the extreme and vigorously promoted the compression technology. In the condition that the cpu performance of modern machines is blowout, the reduction of IO and memory usage is particularly important. compression technology will certainly be a common technology in the future. Now, this technology is becoming more and more mature, so that we can use this

brief introduction to exadata (oracle all-in-one) in an oracle Open Class. Here I would like to make a simple record and start with an all-in-one machine to solve four problems. (1) how to solve the performance problems caused by traditional database deployment? Traditional database deployment: Storage layer: 1. Increasing the I/O bottleneck of data volume; 2. unevenly distributed data; Network Layer: insufficient bandwidth Server layer: excessive Da
