ISG Issue faced in EBS R12.2

Issue 1:  When clicking on view WADL http 500 is returned

• cd $COMMON_TOP/java/lib
• Check  isgagent.zip  exists. If yes, give it full permissions (777).
• Recompile jar files using adadmin.
• Bounce the Oracle Application Framework server and retest

Issue 2: Modifying Existing REST Service, not reflected.

• cd $INST_TOP/soa/isgagent.properties   
• ##Add the below parameter
• ISG_CLEAR_JPUB_CACHE=YES
• Bounce all the appsTier services

Issue 3: ISG REST deployment - failed to be authenticated.

• Check the UMX|APPS_SCHEMA_CONNECT role has been assigned to ASADMIN user:

select role_name from wf_user_roles where user_name='ASADMIN';

select role_name from wf_user_role_assignments where user_name='ASADMIN';

If missing, run "Workflow Directory Services User/Role Validation" Program 

• Ensure you can log into EBS front end using ASADMIN user.
• Ensure the the following SQL returns the proper value:

select fnd_vault.get('ISG','ASADMIN') from dual;

• If this value is incorrect / not the same a login password run & then re-check this is correct password:

@$FND_TOP/sql/afvltput.sql ISG ASADMIN <password>

• Ensure the following SQL returns a 'Y".

select fnd_web_sec.validate_login('ASADMIN','<password>') from dual;
