ethraza Posted June 11, 2005 Report Share Posted June 11, 2005 Hi! I posted this to ask how to set bigpages in Mandriva Linux LE 2005. Becose I think this will resolv my problem. But I'll describe my problem here, if sombody knows... I have installed Mandriva LE2005 Download Edition on a Dell PowerEdge 1850 with 4GB of memory, and Oracle 9i. All is ok but I cannot create a DB with the SGA greater than 1.7GB. Why? If I have 4GB of memory the max size of SGA is 2.7, dont't? I get some tricks from net and applyed all but the bigpages part don't worked, so I think this maybe helps me. Here is my important files or part of that files: lilo.conf (kernel-smp-2.6.11.6mdk-1-1mdk - Note the bigpages option, is part of the trick that don't work.): image=/boot/vmlinuz label="linux" root=/dev/sda5 initrd=/boot/initrd.img append="acpi=ht resume=/dev/sda6 splash=silent bigpages=3100" vga=788 read-only sysctl.conf (This is appended to the end of the original file. The kernel.shm-use-bigpages=2 "is an unknown key" with command sysctl -p.): kernel.shmmax=2147483648 kernel.shmmni=4096 kernel.shmall=2097152 kernel.sem=1000 32000 100 150 fs.file-max=65536 net.ipv4.ip_local_port_range=1024 65000 kernel.shm-use-bigpages=2 kernel.sem=250 32000 100 128 kernel.shmmax=3000000000 df (The tmpfs pointing to /dev/shm with size=3GB is part of the trick, but this worked -): Filesystem Size Used Avail Use% Mounted on /dev/sda5 43G 2,5G 38G 7% / /dev/sda7 88G 3,3G 80G 4% /opt/oracle none 3,0G 0 3,0G 0% /dev/shm cat /proc/meminfo (To you know my meminfo -): MemTotal: 3369412 kB MemFree: 3066224 kB Buffers: 12916 kB Cached: 172724 kB SwapCached: 0 kB Active: 182300 kB Inactive: 86948 kB HighTotal: 2490112 kB HighFree: 2228224 kB LowTotal: 879300 kB LowFree: 838000 kB SwapTotal: 5245180 kB SwapFree: 5245180 kB Dirty: 28 kB Writeback: 0 kB Mapped: 130884 kB Slab: 19624 kB CommitLimit: 6929884 kB Committed_AS: 178836 kB PageTables: 1484 kB VmallocTotal: 114680 kB VmallocUsed: 6520 kB VmallocChunk: 106768 kB cat cpuinfo (To you know my CPUs -): processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Xeon(TM) CPU 2.80GHz stepping : 1 cpu MHz : 2793.436 cache size : 1024 KB physical id : 0 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmovpat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm pni monitor ds_cpl cid xtpr bogomips : 5537.79 processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Xeon(TM) CPU 2.80GHz stepping : 1 cpu MHz : 2793.436 cache size : 1024 KB physical id : 0 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmovpat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm pni monitor ds_cpl cid xtpr bogomips : 5586.94 processor : 2 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Xeon(TM) CPU 2.80GHz stepping : 1 cpu MHz : 2793.436 cache size : 1024 KB physical id : 3 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmovpat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm pni monitor ds_cpl cid xtpr bogomips : 5586.94 processor : 3 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Xeon(TM) CPU 2.80GHz stepping : 1 cpu MHz : 2793.436 cache size : 1024 KB physical id : 3 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmovpat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm pni monitor ds_cpl cid xtpr bogomips : 5570.56 I don't know wath to do anymore.

ethraza Posted November 29, 2005 Author Report Share Posted November 29, 2005 Hehe... now I have HugeTLB on kernel, everything is configured but Oracle still unable ta see more than 1.7GB of memory! F****** Quote Link to comment Share on other sites More sharing options...
ethraza Posted April 8, 2006 Author Report Share Posted April 8, 2006 Oracle 9i 32-Bit version have a limitation that don't let it to see more that 1.7G of memory. They have a patch to work around this in metafile. But, Oracle 10gR2 with Mandriva 2006 work great! See all my memory if I want. Quote Link to comment Share on other sites More sharing options...
