Oracle Database Discussions

Hi,

I am using Oracle Enterprise Linux 5 Update 4 for the Installation of Oracle Database 11g R2 in Linux 32 Bit.

Following is my downloaded zip file linux_11gR2_database_1of2.zip and linux_11gR2_database_2of2.zip. I unzipped

both the files into linux_11gR2_database_1of2 folder for avoiding installation issues and errors.

I have allocated 14 GB Memory as well as same SWAP space (14 GB)  in my Linux OS as per Oracle Documentation.

Following are the etc/sysctl.conf contents

Kernel sysctl configuration file for Oracle Enterprise Linux

#

# For binary values, 0 is disabled, 1 is enabled.  See sysctl(8) and

# sysctl.conf(5) for more details.

# Controls IP packet forwarding

net.ipv4.ip_forward = 0

# Controls source route verification

net.ipv4.conf.default.rp_filter = 1

# Do not accept source routing

net.ipv4.conf.default.accept_source_route = 0

# Controls the System Request debugging functionality of the kernel

kernel.sysrq = 0

# Controls whether core dumps will append the PID to the core filename

# Useful for debugging multi-threaded applications

kernel.core_uses_pid = 1

# Controls the use of TCP syncookies

net.ipv4.tcp_syncookies = 1

# Controls the maximum size of a message, in bytes

kernel.msgmnb = 65536

# Controls the default maximum size of a message queue

kernel.msgmax = 65536

# Controls the maximum shared segment size, in bytes

kernel.shmmax = 4294967295

# Controls the maximum number of shared memory segments, in pages

kernel.shmall = 2097152

fs.file-max = 6815744

kernel.msgmni = 2878

kernel.sem = 250 32000 100 128

kernel.shmmni = 4096

net.core.rmem_default = 262144

# For 11g recommended value for net.core.rmem_max is 4194304

net.core.rmem_max = 4194304

# For 10g uncomment the following line, comment other entries for this parameter and re-run sysctl -p

# net.core.rmem_max=2097152

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

fs.aio-max-nr = 1048576

net.ipv4.ip_local_port_range = 9000 65500

Following are the /etc/security/limits.conf

# Recommended stack hard limit 32MB for oracle installations

My oracle database path is

/u01/app/oracle/Database/11.2.0/orcl

Given proper permissions for user oracle

I run the installer using oracle user as

./runInstaller.sh from the source folder.

Installation goes fine till oracle net configuration assistant. When Database configuration assistant starts
I get the following error ORA-00443 background process “CKPT” did not start.

For this I tried re-installing from the scratch every time I get the same error ORA-00443 background process
sometimes for “DBWR”, sometimes for “PMON”, “SMON” and so on.

Every new Installation gives the new process Error with same code as ORA-00443.

Please correct me,  Where I am wrong. . either in SWAP versus MEMORY, sysctl.conf or limits.conf.

Thanks
