Using Red Hat Enterprise Linux Server release 5.11 (Tikanga) but I need to change the values for shmmax & shmall.vi /etc/sysctl.conf# Controls the maximum shared segment size, in byteskernel.shmmax = 68719476736 # Controls the maximum number of shared memory segments, in pageskernel.shmall = 4294967296fs.suid_dumpable = 1fs.aio-max-nr = 1048576fs.file-max = 6815744kernel.shmall = 2097152kernel.shmmax = 536870912kernel.shmmni = 4096# semaphores: semmsl, semmns, semopm, semmnikernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default=262144net.core.rmem_max=4194304net.core.wmem_default=262144net.core.wmem_max=1048586kernel.shmmax = 4294967295In the above shmax is in three times and shmall is two times mentioned. Where should I change?when I type the command ipcs -lm it shows[oracle@NTSLSRVDBS02 ~]$ ipcs -lm------ Shared Memory Limits --------max number of segments = 4096max seg size (kbytes) = 4194303max total shared memory (kbytes) = 8388608min seg size (bytes) = 1I need to change the values of shmmax and shmall.
Edit sysctl.conf file
