Oracle R12/12i log file (Patch, Clone, Startup/Shutdown)

Log files are useful in troubleshooting issues in Oracle Applications. Here is the list of Log file location in Oracle Applications for Startup/Shutdown, Cloning, Patching, DB & Apps Listener and various components in Apps R12/12i:

A. Startup/Shutdown Log files for Application Tier in R12

Instance Top is new TOP added in R12 (to read more click here)

Startup/Shutdown error message text files like adapcctl.txt, adcmctl.txt…

–Startup/Shutdown error message related to tech stack (10.1.2, 10.1.3 forms/reports/web)
$INST_TOP/apps/$CONTEXT_NAME/logs/ora/  (10.1.2 & 10.1.3)
$INST_TOP/apps/$CONTEXT_NAME/logs/ora/10.1.3/Apache/error_log[timestamp] $INST_TOP/apps/$CONTEXT_NAME/logs/ora/10.1.3/opmn/ (OC4J~…, oa*, opmn.log)$INST_TOP/apps/$CONTEXT_NAME/logs/ora/10.1.2/network/ (listener log)
$INST_TOP/apps/$CONTEXT_NAME/logs/appl/conc/log  (CM log files)

B. Log files related to cloning in R12

Preclone log files in source instance
i) Database Tier – /$ORACLE_HOME/appsutil/log/$CONTEXT_NAME/(StageDBTier_MMDDHHMM.log)

ii) Application Tier – $INST_TOP/apps/$CONTEXT_NAME/admin/log/ (StageAppsTier_MMDDHHMM.log)

Clone log files in target instance

Database Tier – $ORACLE_HOME/appsutil/log/$CONTEXT_NAME/ApplyDBTier_<time>.log
Apps Tier  – $INST_TOP/apps/$CONTEXT_NAME/admin/log/ApplyAppsTier_<time>.log

If your clone on DB Tier fails while running  (Check metalink note – 415020.1)
During clone step on DB Tier it prompts for “Target System base directory for source homes” and during this you have to give like /base_install_dir like ../../r12 and not oracle home like ../../r12/db/tech_st_10.2.0

This is kumar. I got one issue after cloning R12.1.1, http_server is not up.By checking log file like it shows like

Apache has not been designed to serve pages while running as root user.There are known race conditions that will allow any local user to read any file on the system. If you still desire to serve pages as root then……………………..

like that

I want to do import of selected objecsts in oracle i have a full export of that schema.Is there is any way…

Sri says March 26, 2015

Hi Arul,

We are trying to use dmstool for Oracle EBS 12 application server 10.1.3 to list the performance metrics.Command works fine but displays very few metrics and most of the key metrics are missing.

dmstool -list -a opmn://hostname:requestport
dmstool -dump format=xml -a opmn://hostname:requestport

I dont see errors and output is displayed but with lot of missing metrics for key tables that are not found as given below


As per Oracle documents it is told that OC4J home must be running to use DMS, but when check the processes using adopmnctl we are not able to see OC4j Home.

adopmnctl status
it shows the below status as alive.

ias-component | process-type | pid | status
OC4JGroup:default_group | OC4J:oafm | 2383 | Alive
OC4JGroup:default_group | OC4J:forms | 2382 | Alive
OC4JGroup:default_group | OC4J:oacore | 2381 | Alive
HTTP_Server | HTTP_Server | 2380 | Alive

Is OC4j home not available with Oracle EBS 12 ? or what is the equivalent instance to use dmstool?
Please Help


Karthi says May 9, 2016

We have changed the default oacore logs to non default location. On similar fashion we need to change oacore_server.out files generated in $EBS_DOMAIN_HOME/servers//logs. Please advise how to change this .out file being generated to different location? Where it is configured
