First tried to start up dbconsole:
$ emctl start dbconsole OC4J Configuration issue. /home/oracle/oracle1123/product/oc4j/j2ee/OC4J_DBConsole_perf234-target1.delphix.com_SOE60G #ff0000;">not found.
\OK, missing file. EM wasn’t configured for this database, make sense. Let’s configure it
$ emca -config dbcontrol db -repos create ... #ff0000;">SEVERE: Dbcontrol Repository already exists. Fix the error(s) and run EM Configuration Assistant again in standalone mode.Looks like there is already a repository, so lets configure EM with out making the repository
# emca -config dbcontrol db #ff0000;">WARNING: ORA-00942: table or view does not exist SEVERE: The existing database you have specified has Grid Control repository. This operation is not supported.Hmm, what table is missing? Put db in sql trace mode to see what SQL statement ran into the 942 error
sqlplus / as sysdba alter database set sql_trace=true exitrerun and grep for 942 in trace files in user_dump_dest
cd /home/oracle/oracle1123/diag/rdbms/soe60g/SOE60G/trace grep 942 *this show a dozen or so files.
Open each one up and searched for 942 and found two distinct SQL queries:
SELECT ATTRIBUTE,SCOPE,NUMERIC_VALUE,CHAR_VALUE,DATE_VALUE FROM #ff0000;">SYSTEM.PRODUCT_PRIVS WHERE (UPPER('SQL*Plus') LIKE UPPER(PRODUCT)) AND (USER LIKE USERID) select count(*) from #ff0000;">sysman.mgmt_versions where status > 0 and component_mode like 'SYSAUX' and component_name in ('DB','CORE')The first table is from not having run $ORACLE_HOME/sqlplus/admin/pupbld.sql
Second is the problem emca was running into. Let’s look at sysman’s objects and see what’s there.
sqlplus sysman/sys select object_name from user_objects; -> no rows returnedOK, sysman looks empty , let’s drop it and recreated it
sqlplus / as sysdba drop user sysman cascade; drop user MGMT_VIEW cascade;someone’s blog had suggested dropping the following but I didn’t
# drop role MGMT_USER; # drop public synonym MGMT_TARGET_BLACKOUTS; # drop public synonym SETEMVIEWUSERCONTEXT; # host port SID # $ORACLE_HOME/sysman/admin/emdrep/bin/RepManager antarctic 2483 sprod -action drop # ./emca -repos creatererun emca
$ emca -config dbcontrol db -repos create .... Do you wish to continue? [yes(Y)/no(N)]: y Apr 20, 2013 7:27:51 AM oracle.sysman.emcp.EMConfig perform INFO: This operation is being logged at /home/oracle/oracle1123/cfgtoollogs/emca/SOE60G/emca_2013_04_20_07_27_38.log. Apr 20, 2013 7:27:51 AM oracle.sysman.emcp.ParamsManager checkListenerStatusForDBControl #ff0000;">WARNING: ORA-01031: insufficient privileges Apr 20, 2013 7:27:51 AM oracle.sysman.emcp.EMConfig perform SEVERE: Database connection through listener failed. Fix the error and run EM Configuration Assistant again. Some of the possible reasons may be: 1) Listener port 1521 provided is incorrect. Provide the correct port. 2) Listener is not up. Start the Listener. 3) Database service SOE60G is not registered with listener. Register the database service. 4) Listener is up on physical host and ORACLE_HOSTNAME environment variable is set to virtual host. Unset ORACLE_HOSTNAME environment variable. 5) Listener is up on virtual host. Set environment variable ORACLE_HOSTNAME=. 6) /etc/hosts does not have correct entry for hostname.
Notice the ORA-01031. Hmm, I can connect as sqlplus / as sysdba but connecting as sysdba through the listener requires a password file. Let’s see if password files are set up
sqlplus / as sysdba show parameters remote_login_passwordfile remote_login_passwordfile string EXCLUSIVEthat’s set correct, but is there a password file?
cd $ORACLE_HOME/dbs ls orapw$ORACLE_SID ls: cannot access orapwdSOE60G: No such file or directorynot there, let’s create it
orapwd FILE=orapw$ORACLE_SID ENTRIES=30
now emca works !
Now what URL to I use to access OEM for the second database?
It’s the same URL as the first database but with different port. We can find the ports for each database in the following file
cat $ORACLE_HOME/install/portlist.ini Enterprise Manager Console HTTP Port (o1123) = 1158 Enterprise Manager Agent Port #ff0000;">(o1123) = 3938 Enterprise Manager Console HTTP Port (SOE60G) = 5500 Enterprise Manager Agent Port #ff0000;">(SOE60G) = 1830
After the above steps, one of the bizarre things I ran into was being able to access OEM database page in Chrome but nothing else. Coming into OEM, I’m first asked for a login. I login as system, I see the database home page, then if I click on the performance tab, then I get prompted for the login again. I then login again, and I’m back at the database home page. No matter what tab I click, I end up back at the database home page after giving login credentials.
In Firefox, though once I login, I can go to any of the other tabs and it works!
PS when running emca above I was prompted for a number of variables. didn’t try this, but looks like all the arguments can be given in the command line
emca -repos create -silent -ORACLE_HOSTNAME perf234-target1 -SID SOE60G -SERVICE_NAME SOE60G -ORACLE_HOME /home/oracle/oracle1123/product -SYS_PWD sys -DBSNMP_PWD sys -SYSMAN_PWD sys -HOST_USER oracle -HOST_USER_PWD -PORT 1521
Post Script II:
Never seen this one before and it was super annoying. I set up a VM in Virtual Box on my Mac with LINUX and Oracle 126.96.36.199 and OEM. On the VM I could access OEM but not from my Mac. On my Mac I kept getting
