SOLUTION

Source ENV

2. Set an alias for the correct orapki.
alias orapki=$FMW_HOME/oracle_common/bin/orapki
Verify using which orakpi

3. Create a new wallet with an acceptable self-signed certificate in $HOME/ss(You can use any location. Preferred is $HOME/ss).
Eg:
$ mkdir ~/ss
$ cd ~/ss
$ orapki wallet create -wallet . -auto_login_only
$ orapki wallet add -wallet . -dn "CN=FMWSmallCircleOfTrust" -asym_alg RSA -keysize 2048 -sign_alg sha256 -self_signed -validity 3652 -auto_login_only
$ orapki wallet display -wallet .

4. Go to the instance directory.
$ cd $FMW_HOME/webtier/instances/$iName

5. Find the default wallets used by this instance.
Eg:
$ find . -name cwallet.sso
./config/OPMN/opmn/wallet/cwallet.sso
./config/OHS/EBS_web/proxy-wallet/cwallet.sso
./config/OHS/EBS_web/keystores/default/cwallet.sso

6. Verify that each wallet only contains the self-signed certificate.
$ find . -name cwallet.sso | while read w ;do echo -e "\n$w"; orapki wallet display -nologo -wallet $w ;done
If it is a default wallet, each wallet should list one "User Certificate" and an identical "Trusted Certificate", as shown in the following example:
$./config/OPMN/opmn/wallet/cwallet.sso
Requested Certificates:
User Certificates:
Subject: CN=Self-Signed Certificate for EBS_web_OHS1\20,OU=OAS,O=ORACLE,L=REDWOODSHORES,ST=CA,C=US
Trusted Certificates:
Subject: CN=Self-Signed Certificate for EBS_web_OHS1\20,OU=OAS,O=ORACLE,L=REDWOODSHORES,ST=CA,C=US

7. Copy the new SHA-256 signed wallet to all default wallet locations.
$ find . -name cwallet.sso | while read w ; do echo $w; cp -p ~/ss/cwallet.sso $w ; done
This avoids modifying the OPMN and OHS configuration files to point to a different wallet (or wallet directory).

With the new wallet in place, OPMN and OHS should be able to start.

You can use adopmnctl.sh start ;

adapcctl.sh start to verify startup of just OPMN and OHS.

Alternatively, you can run adstrtal.sh to attempt to start everything simultaneously.

5. Retest the issue.

Services are up and running.
