Please help

I installed Oracle 8.1.7 on a Sun Blade 100 running Solaris 8 following the Installation Guide and this mailing list.

I have a machine like this.
SUN Blade 100 with 2GB membory, 7GB disk space for /opt which is the place to install oracle software and data files.

sysdef command below:

........

  swap files device swaplo block &#31354;&#12365;&#23481;&#37327;

     1  min shared memory segment size (SHMMIN)

   200 shared memory identifiers (SHMMNI)     20 max attached shm segments per process (SHMSEG)

........

All installation went well. I created database by DBCA(select:Typical).
That results in an SGA:

  Total System Global Area 692265120 bytes

And inittestdb.ora is below:

db_name = "testdb"
db_domain = sd1.agrex.co.jp

instance_name = testdb
service_names = testdb.sd1.agrex.co.jp
control_files = ("/opt/oradb01/app/oracle/oradata/testdb/control01.ctl",
                 "/opt/oradb01/app/oracle/oradata/testdb/control02.ctl",
                 "/opt/oradb01/app/oracle/oradata/testdb/control03.ctl")

open_cursors = 300
max_enabled_roles = 30
db_block_buffers = 62322
shared_pool_size = 170180812
large_pool_size = 614400
java_pool_size = 0
log_checkpoint_interval = 10000
log_checkpoint_timeout = 1800
processes = 50
log_buffer = 163840
user_dump_dest = /opt/oradb01/app/oracle/admin/testdb/udump db_block_size = 8192
remote_login_passwordfile = exclusive
os_authent_prefix = ""
compatible = "8.1.0"
sort_area_size = 65536
sort_area_retained_size = 65536

There were no apparent problems during Installation and creation. However, when I try to run sqlplus on the machine running oracle installed, I get the following:

ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist SVR4 Error: 2: No such file or directory

I checked the settings in /etc/system and DBSTART up and listener up and environment parameter(ORACLE_SID,ORACLE_BASE,ORACLE_HOME) and path.
I have checked that but that does not seem to be the problem.

I cannot figure out why I cannot connect to database.

Any suggestion on troubleshooting,please.
