Oracle golden gate comparison

  1. 1. DATABASE REPLICATION SO ORACLE GOLDEN GATNo. Category 1 HETEROGENEITY2 RECOVERABILITY AND RESTARTABILITY3 PERFORMANCE AND OVERHEAD4 SINGLE PRODUCT VS. MULTIPLE PRODUCTS5 EASE OF TROUBLESHOOTING
  2. 2. DATABASE REPLICATION SOFTWARE ORACLE GOLDEN GATEOracle Goldengate key differenciatorGoldenGate’s database and platform support is very extensive,already proven, with real customer referenceExample of supported DB:- Oracle- DB2 OS/390- DB2 UDB- Microsoft SQL Server- Sybase- Ingres- Enscribe- SQL/MP- SQL/MX- Teradata- My SQLExample of supported OS:- Windows 2000, 2003, XP- Linux- Sun Solaris- HP-UX- IBM AIX- HP NonStop- TRU64- IBM z/OS, LUWGoldenGate persists change data into Trail files and has check-pointing system that allows to “trace” a transaction through ourreplication flow, thus OGG persisted Trail files allow you to replaytransactions. When the target system or the network is down for anyreason, GoldenGate continues to capture new transactions to bedelivered when the target system or the network is again availableGoldenGate can handle higher load volumes and is less intrusive on the source database than similar products. For exampcustomer site, we found out that other product need to have 6-7 processes running on the source database server, while OprocessesGoldenGate is only one product, which make it easier to install andconfigure (take less than 1 day, compared to other similar product thatis complex to install and it takes usually several days)GoldenGate allows users to access/search Trail files and allows fasttroubleshooting.
  3. 3. SOFTWAREGATE Compared to other products With some product, although they claimed to support multiple DB, but it use some customization to do that, for example some product need to use triggers to capture from Sybase, and some product don’t have capture from Teradata. Also even though some product sometimes claim to support Oracle DB, they don’t have any real references for real time capturing from Oracle DB and they don’t usually fully support Oracle ASM. Some products has problems with restarting processes because of their queue approach for managing change data (versus our persisted Trail files where you can replay transactions). Most of the time they need to re-instantiate every table after a server shuts down or process is killed due to network hiccups, disk corruption, etc. Also most similar product doesn’t handle network environments that are not stable and can lose transactions after a network error.ntrusive on the source database than similar products. For example, in one ofve 6-7 processes running on the source database server, while OGG only need 2 Some product need multiple products for data integration and replication for HA purposes, thus requires the purchase of multiple products Similar product usually doesnt allow following transactions during the data movement, so it need longer time to do troubleshooting on Prod environment
