O talosaga Java e mafai ona fa'aogaina lelei le advantage o foliga fou P10 ISA i luga o faiga faʻaogaina o loʻo faʻaogaina i le P10 mode e ala i le faʻaogaina o le Java runtime versions o loʻo lisi atu i lalo pe fou:
Java 8

IBM SDK 8 SR6 FP36
IBM Semeru Runtime Open Edition 8u302: openj9-0.27.1

Java 11

IBM Semeru Runtime Certified Edition 11.0.12.1: openj9-0.27.1
IBM Semeru Runtime Open Edition 11.0.12.1: openj9-0.27.1

Tele Itulau
O le fautuaga lautele mo le tele o faʻamaumauga a Oracle i luga o le AIX o le faʻaaogaina o le 64KB itulau lapoʻa ae le o le 16MB itulau lapoʻa mo le SGA. E masani lava, 64 KB itulau e maua mai toetoe lava tutusa
faʻamanuiaga faʻatinoga e pei o 16 MB itulau e aunoa ma se pulega faʻapitoa.
TNS Faafofoga
Oracle 12.1 database ma faʻasalalauga mulimuli ane e ala i le le mafai ona faʻaogaina itulau 64k mo tusitusiga, faʻamaumauga, ma faʻaputu. Ae ui i lea, mo le TNSLISTENER o loʻo faʻaogaina pea itulau 4k mo tusitusiga, faʻamaumauga, ma faʻaputu. I
fa'ataga 64k itulau mo le fa'alogologo fa'aaoga le fa'atonuga fa'atau atu a'o le'i amataina le faiga fa'alogologo. Manatua o loʻo tamoʻe i se siosiomaga faʻavae ASM lea e alu ese le tagata faʻalogo
GRID_HOME ae le o ORACLE_HOME.
O faʻamaumauga mo le "strictly setenv" poloaiga na suia i le 12.1 poʻo faʻasalalauga mulimuli ane. O le -t poʻo le -T na aveese mo le -env poʻo -envs. I totonu ole siosiomaga Oracle Listener seti ma auina atu i fafo:
– LDR_CNTRL=FA’ATA’IGA=64K@TEXTPSIZE=64K@STACKPSIZE=64K - VMM_CNTRL=vmm_fork_policy=COR (fa'aopoopo le 'Copy on Read' command)
Syntax fa'asoa
O le LDR_CNTRL=SHARED_SYMTAB=Y fa'atulagaina e le mana'omia ona tu'u fa'apitoa ile 11.2.0.4 po'o fa'asalalauga mulimuli ane. O filifiliga feso'ota'iga tu'ufa'atasi e fa'atonutonuina lenei fa'atulagaga ma e le toe mana'omia le fa'atulagaina fa'apitoa. E le fautuaina le fa'atulagaina o le LDR_CNTRL=SHARED_SYMTAB=Y i le 12c po'o le fa'asalalauga mulimuli ane.
Gaugau Mea Fa'atonu
Ose tulaga taua lea i totonu ole siosiomaga RAC pe a fa'aogaina LPARs fa'atasi ai ma gaioiga gaugau e mafai. Afai e le fetuutuuna'i le tulaga lea, e maualuga le tulaga lamatia o le tuliesea o pona RAC i lalo ole tulaga mama o le mamafa o galuega. Scheda -p -o vpm_xvcpus=2
VIOS & RAC Feso'ota'i
O se feso'ota'iga tu'ufa'atasi 10G (ie, 10G Ethernet Adapter) e fautuaina e fa'atauva'a ina ia lava le fa'alava mo fela'ua'iga fa'aletonu taimi. RAC fa'apipi'i fe'avea'i - feso'ota'iga fefa'ataua'iga e tatau ona tu'ufa'atasi ae le fa'asoa. Fetufa'aiga o feso'ota'iga e mafai ona mafua ai le tuai o le taimi e o'o atu ai i fa'afitauli tautau/fa'ate'a.
Feso'ota'iga Fa'atinoga
O se faʻamatalaga faʻapipiʻi fesoʻotaʻiga umi lea mo Oracle i luga o le AIX, e ui o le faaletonu e tumau pea ile 0. TCP Seti o rfc1323=1
Fa'amatalaga sili atu
Va'ai le feso'ota'iga: Puleaina o le mautu ma le fa'atinoga o fa'amaumauga a le Oracle Database o lo'o fa'aogaina le AIX i luga ole Power Systems e aofia ai le POWER9
