Maitiro ekutarisa⁤ ndangariro kushandiswa muOracle Dhijitari yeExpress yeDatabase?

Mune dhatabhesi reOracle, kushandiswa kwakanaka kwendangariro kwakakosha kuti uve nechokwadi chekushanda kwehurongwa. Memory muOracle inoshandiswa kuchengetedza data mu ⁣cache,⁤ kumhanya mivhunzo, nekuchengetedza kuvimbika kwe ⁤database. Naizvozvo, zvakakosha kuti ⁢kunyatso tarisisa mashandisirwo endangariro kuti uone zvingangoita mabhodhoro kana nyaya dzekuita. Muchikamu chino, tichaongorora akasiyana matekiniki uye maturusi ekutarisa⁢ uye kuongorora mashandisiro endangariro. muOracle Database Express Edition.

1. Kushandisa Oracle Memory Manager: Oracle Database Express Edition inosanganisira chishandiso chinonzi "Oracle Memory Manager" chinokutendera kuti utore uye utarise mashandisirwo endangariro. Tichishandisa Oracle Memory Maneja, tinogona kuona kuti ndeapi matunhu endangariro ari kushandisa zvakanyanya zviwanikwa uye kutora matanho ekugadzirisa mashandisiro azvo.

2. Kugadzirisa Oracle Activity Monitor: Chinoongorora Chiitiko Oracle ndeye yakavakirwa-mukati dhatabhesi chishandiso chinopa tarisiro yekuita uye kushandiswa kwezviwanikwa. munguva chaiyo. Ichi chishandiso⁢ chinokutendera kuti utarise kushandiswa kwendangariro, pamwe nezvimwe zviwanikwa zvakaita seCPU, I/O, uye ⁤network. Nekugadzirisa Oracle Activity Monitor kuratidza mametric ane chekuita nendangariro, tinogona kuwana tarisiro yakadzama yemashandisirwo ari kuitwa ndangariro mukati mebhodhi. nguva chaiyo uye kuona chero matambudziko kana kusashanda.

3. Kushandisa Mibvunzo yeSQL: Oracle inopa nhevedzano yemaonero uye matafura epivot anopa ruzivo rwakadzama nezvekushandiswa kwendangariro uye zvimwe zviwanikwa zvehurongwa. Semuenzaniso, iyo "V$SGASTAT" maonero anopa nhamba dzepasi rose yakagovaniswa kushandiswa kwendangariro, nepo "V$BUFFER_POOL_STATISTICS" tafura inoratidza ruzivo nezve data cache performance. Kuburikidza neSQL queries⁤ tichishandisa maonero aya uye matafura epivot, tinogona kuwana mishumo yakadzama nezve ⁤memory⁤ mashandisirwo uye nekuiongorora kuti tione chero nyaya kana matambudziko.

Muchidimbu, kutarisa kushandiswa kwendangariro muOracle Database Express Edition kwakakosha kuti uve nechokwadi chekushanda kwakakwana uye kudzivirira zvipingaidzo. Kushandisa zvishandiso⁤ seOracle Memory Manager, iyo Chinoongorora Zviitiko Kubva kuOracle uye SQL mibvunzo kune maonero uye pivot matafura, tinogona kuwana yakadzama yekuona mashandisiro endangariro munguva chaiyo uye kutora matanho akakodzera kukwirisa kuita kwayo.
