Oracle 10g vs 11g
Oracle databases yog cov khoom lag luam ntsig txog kev tswj hwm cov txheej txheem tsim thiab xa tawm los ntawm Oracle Corporation. Qhov tseeb version ntawm Oracle databases yog Oracle 11g, thawj zaug tso tawm thaum lub Cuaj Hlis 2008; nws ua tiav Oracle 10g. Cov qauv no yog ib feem ntawm kev hloov pauv txuas ntxiv ntawm Oracle databases txij li xyoo 1980s. Txhua tus tshiab version muaj cov tshiab patch teeb tso tawm tsis tu ncua, qhov tseem ceeb tshaj plaws uas yog hu ua kev tso tawm. Lub hom phiaj tseem ceeb ntawm txhua qhov kev hloov kho tshiab yog txhawm rau ua kom muaj kev ua tau zoo thiab ua kom muaj peev xwm tshaj qhov qub version. Yog li ntawd muaj ntau yam tshiab hauv 11g ua rau saum cov uas twb muaj nyob rau hauv 10g. Cov no muab kev muaj peev xwm zoo dua rau cov thawj tswj hwm cov ntaub ntawv (DBAs) los tswj lawv cov chaw khaws ntaub ntawv ntau qib uas tau txais ntau dua thiab loj dua xyoo.
Oracle 10g
Oracle 10g yog qhov hloov kho dua tshiab los ntawm Oracle 9i. Nws yog qhov ruaj khov heev los ntawm qhov tawm teeb nrog ntau cov kab hauv 9i tsau thiab nrog tus tswv ntawm cov yam ntxwv tshiab. Feem ntau nws muab daim phiaj xam los ntawm kev muab CPUs thiab cov ntaub ntawv. Txog qhov kawg no, Oracle Enterprise Tus Thawj Coj (OEM) tau muab cov phiaj xwm tswj hwm muaj zog. Cov ntawv no kuj tau muab kev txhim kho rau cov kev txuas ntxiv xws li Oracle RAC (Cov Ntawv Thov Tiag), Oracle Data Guard thiab Oracle Stream. 10g coj txog kev ua haujlwm ntawm kev tswj hwm feem ntau los ntawm kev qhia txog ntau yam kev tswj tus kheej xws li kev siv cov ntaub ntawv txheeb xyuas cov ntaub ntawv, kev siv lub cim xeeb sib koom ua ke, kev tswj xyuas qhov chaw khaws cia, thiab automated disk raws li thaub qab thiab rov qab.
Oracle 11g
Oracle 11g thawb lub hnab ntawv ntxiv, txhim kho ntau yam ntawm cov yam ntxwv pom hauv 10g. Nws muab cov khoom tshiab xws li Oracle Application Express, Oracle SQL Developer, Oracle Real Application Testing, Oracle Configuration Manager (OCM), Oracle Warehouse Builder, Oracle Database Vault thiab Oracle Shadow Copy Service. Yog li 11g muab kev ua tau zoo dua thiab nws qhov kev tso tawm 2 tau npaj rau kev ua haujlwm tshiab xws li Windows 7, Server 2008 thiab cov ntawv tshiab ntawm Linux, Unix, Solaris, thiab lwm yam.
Qhov txawv ntawm 10g thiab 11g yog dab tsi?
Piv nrog 10g, 11g muab kev yooj yim dua, txhim kho thiab kev tswj hwm lub cim xeeb thiab muaj peev xwm zoo dua los kuaj xyuas qhov tsis raug los ntawm kev tsim kho vaj tse los tiv thaiv, ntes, kuaj xyuas, thiab pab daws qhov teeb meem tseem ceeb hauv database, nrog rau, cov teeb meem kev ua haujlwm tsawg. Nws muab cov kev ntsuas pom tsis pom, kab ntawv virtual, kev faib cov lus thiab lub peev xwm los kho cov lus uas muaj cov ntaub ntawv pom thaum nyob online. Qhov sib txawv loj ntawm ob yog qhov tshiab kev ruaj ntseg nta pom nyob rau hauv 11g xws li zoo dua lo lus zais-raws li authentication nrog cov ntaub ntawv sib xyaw passwords, encryption ntawm tablespace-theem thiab txhim kho cov ntaub ntawv twj tso kua mis encryption thiab compression.
11g txuas ntxiv siv cov ntawv sib txawv siv hauv 10g uas yog Enterprise Edition (EE), Standard Edition (SE), Standard Edition Ib (SE1), Express Edition (EX) thiab Oracle Database Lite rau cov khoom siv txawb.
Zaj lus
Txhua yam, 11g yog qhov kev txhim kho zoo los ntawm 10g nrog ntau yam kev txhim kho zoo ntawm kev hloov kho thev naus laus zis. Cov ntaub ntawv thev naus laus zis uas tau zoo hauv 10g tau dhau los ua qhov zoo dua hauv 11g, qhov txiaj ntsig tseem ceeb rau DBAs, uas nyob ntawm nws txhua hnub. Nws yog ib qho uas cov koom haum tsis siv tag nrho cov yam ntxwv ntawm Oracle database. Yog li ntawd, cov txiaj ntsig ntawm kev hloov kho tshiab yuav tsum tau siv kom zoo rau lub koom haum kom txo lawv cov nqi ntawm cov tswv cuab, kev poob qis thiab nce kev ua tau zoo, uas 11g tuaj yeem xa tuaj.
