Where do concurrent request log files and output files go?
The concurrent manager first looks for the environment variable $APPLCSF
If this is set, it creates a path using two other environment variables:
$APPLLOG and $APPLOUT
It places log files in $APPLCSF/$APPLLOG
Output files go in $APPLCSF/$APPLOUT
So for example, if you have this environment set:
$APPLCSF = /u01/appl/common
$APPLLOG = log
$APPLOUT = out
The concurrent manager will place log files in /u01/appl/common/log, and
output files in /u01/appl/common/out
Note that $APPLCSF must be a full, absolute path, and the other two are
directory names.
If $APPLCSF is not set, it places the files under the product top of the application associated with the request. So for example, a PO report would go under $PO_TOP/$APPLLOG and $PO_TOP/$APPLOUT
Logfiles go to: /u01/appl/po/9.0/log
Output files to: /u01/appl/po/9.0/out
Of course, all these directories must exist and have the correct permissions.
Note that all concurrent requests produce a log file, but not necessarily an output file.
Where are the log files located in R12?
For DBA’s who mostly worked on 11i environments, finding the log files (Concurrent manager log, apache log etc.,) on a R12 environment might pose a threat initially, because these log files no longer reside in their old location ie., $APPLCSF/$APPLLOG or $APACHE_TOP/Apache/logs.
In R12, the log files are located in $LOG_HOME (which translates to $INST_TOP/logs)
Concurrent Reqeust related logs
$LOG_HOME/appl/conc -> location for concurrent requests log and out files
$LOG_HOME/appl/admin -> location for mid tier startup scripts log files
Apache Logs (10.1.3 Oracle Home which is equivalent to iAS Oracle Home)
$LOG_HOME/ora/10.1.3/Apache -> Location for Apache Error and Access log files
$LOG_HOME/ora/10.1.3/j2ee -> location for j2ee related log files
$LOG_HOME/ora/10.1.3/opmn -> location for opmn related log files
Forms & Reports related logs (10.1.2 Oracle home which is equivalent to 806 Oracle Home)
$LOG_HOME/ora/10.1.2/forms
$LOG_HOME/ora/10.1.2/reports
