Steps for Clean restart OMS.
===========================

1.Shutdown all the OMS related processes

$<OMS_HOME>/bin/emctl stop oms -all -force

Kill if there are any stale processes running out of the installation path for OMS.

ps -ef | grep EMGC_ADMINSERVER

ps -ef | grep EMGC_OMS1

ps -ef | grep java

kill any of the above processes which are running from the OMS $ORACLE_HOME using 'kill -9 <PID>'

2. Checking for the invalid objects in the repository shows several objects in INVALID status:

SQL> select object_name, object_type, owner from dba_objects where status = 'INVALID';

Ensure that none of the SYSMAN, SYSMAN_RO and SYSMAN_MDS objects are invalid

3. Remove the *.DAT and *.lok files from the paths below:

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_OMS1/data/store/diagnostics/WLS_DIAGNOSTICS000000.DAT

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_OMS1/data/store/default/_WLS_EMGC_OMS1000000.DAT

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_ADMINSERVER/data/store/diagnostics/WLS_DIAGNOSTICS000000.DAT

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_ADMINSERVER/data/store/default/_WLS_EMGC_ADMINSERVER000000.DAT

and

$ find . -name "*.lok"

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/config/config.lok

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_OMS1/data/ldap/ldapfiles/EmbeddedLDAP.lok

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_OMS1/tmp/EMGC_OMS1.lok

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_ADMINSERVER/data/ldap/ldapfiles/EmbeddedLDAP.lok

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_ADMINSERVER/tmp/EMGC_ADMINSERVER.lok

4. Go to the AdminServer directory which is in $EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_ADMINSERVER/data

5. Create a backup of ldap folder and delete the current one.

6. Go to the $EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_OMS1/data directory

7. Create a backup of ldap folder in this path and delete the current one.

8. Move all the logs from below locations to a new folder by creating a directory named old_logs_dir

$EM_INSTANCE_BASE/gc_inst/WebTierIH1/diagnostics/logs/OHS/ohs1

$EM_INSTANCE_BASE/gc_inst/WebTierIH1/diagnostics/logs/OPMN/opmn

$EM_INSTANCE_BASE/gc_inst/user_prolojects/domains/GCDomain/servers/EMGC_OMS1/logs

$EM_INSTANCE_BASE/gc_inst/user_projects/domains/GCDomain/servers/EMGC_ADMINSERVER/logs

9. start the OMS

$<OMS_HOME>/bin/emctl start oms
