Logging Configuration

You can choose to have multiple log files or a single log file. Multiple log files are the

default. If you choose the single log file option, all the output is sent to a single log file

(that is, servlet.log).

Switching From Multiple Log Files to a Single Log File

If you are switching from the multiple log files option (the default) to the single log file

option, perform the following steps:

1. Stop the NSJSP container as described under Stopping NSJSP on page 2-6.

2. Navigate to your /conf subdirectory, as follows:

cd iTPWS_INSTALL_DIR/servlet_jsp/conf

3. Use the DIFF program to compare the iTP_server.xml with the

iTP_server.xml.sample and save the changes.

4. Back up the iTP_server.xml file.

5. Copy the iTP_server-singleLog.xml.sample to the iTP_server.xml file.

6. Delete the iTP_server.xml.sample and create the

iTP_server.xml.sample by symbolically linking to the iTP_server-

singleLog.xml.sample file, as follows:

ln -s iTP_server-singleLog.xml.sample iTP_server.xml.sample

7. Migrate the changes saved in step 3 to the iTP_server.xml file.

8. Change the Stderr from servlet_error.log to servlet.log in the

servlet.config file, as follows:

Stderr $root/logs/servlet.log

9. Restart the NSJSP container.
