adapcctl.sh: exiting with status 204


$ORACLE_HOME/Apache/Apache/logs/xml.log shows:

pid file /xxx/inst/apps/XXX/pids/10.1.3/Apache/httpd.pid overwritten

An unclean shutdown of previous Apache may have occurred.
 
$ORACLE_HOME/Apache/Apache/logs/error.log shows:

httpd: could not log pid to file /xxx/inst/apps/XXX/pids/10.1.3/Apache/httpd.pid
fopen: Permission denied

-- Steps To Reproduce:
The issue can be reproduced at will with the following steps:
1. Stop services as user root.
2. Re-start the services.

Cause:
The services were shut down using user root, and the file httpd.pid cannot be opened by oracle user.

Solution:

-- To implement the solution, please execute the following steps:

1. Check if root owns file httpd.pid:
/xxx/inst/apps/XXX/pids/10.1.3/Apache/httpd.pid

$ cd /xxx/inst/apps/XXX/pids/10.1.3/Apache
$ ls -lart
-rw-r--r-- 1 root system 7 Nov 16 15:10 httpd.pid

Issue 5:
You are running adapcctl.sh version 120.6.12000000.4
Starting OPMN managed Oracle HTTP Server (OHS) instance ...
adapcctl.sh: exiting with status 204

Review the HTTP log file. The error is very clear about the missing soft link. It would show this error:
...
<physical Path>/10.1.3/Apache/Apache/bin/apachectl startssl: execing httpd
<physical Path>/10.1.3/Apache/Apache/bin/httpd: error while loading shared
libraries: libdb.so.2: cannot open shared object file: No such file or directory
...

Soft link libdb.so.2 is missing.

Solution:

To implement the solution, please execute the following steps:

1. Shut down all Oracle Application Services.

2. As the unix root user, create a soft link as follows:

ln -s /usr/lib/libgdbm.so.2.0.0 /usr/lib/libdb.so.2
3. Start up all Oracle Application Services.

Error: Failed to open the wallet [Hint: incorrect path, incorrect password, bad wallet, ...]
(Server ebsdev1.snapbs.com:443, wallet file:/sid/inst/apps/hostname/certs/Apache)

Solution:

Then check the $ORACLE_HOME/opmn/conf/opmn.xml and make sure ssl-enabled is set:
<ias-component id="HTTP_Server">
<process-type id="HTTP_Server" module-id="OHS">
<module-data>
<category id="start-parameters">
<data id="start-mode" value="ssl-enabled"/>
</category>
</module-data>
<process-set id="HTTP_Server" numprocs="1"/>
</process-type>
