Problem Description:<\/strong> In production environment we have two nodes and it\u2019s clustered. The environment has OAS and Oracle Access Manager Products installed in same node. I have seen issue like OC4J not coming up while restarting the osinfra services in one node. Previously everything was working fine, unable to understand what happen suddenly.<\/p>\n

Cause:<\/strong> \u00a0Somehow LBR hostname is missed in one node. SSO is using LBR to get OID connection.<\/p>\n

Workaround summary,<\/strong><\/p>\n

1. Stop the osinfra service or kill the (OAS) process manually since the pid are catch hold by oracle user<\/p>\n

2. Start the OID service [oracle_home\/opmn\/bin]$.\/opmnctl startproc process-type=OID<\/p>\n

Confirmed whether ldapbind is happening or not<\/p>\n

3. [oracle_home\/bin]$ .\/ldapbind -h <oid_hostname> -p <oid_non_ssl_port> -D cn=orcladmin -w <pwd><\/p>\n

4. [oracle_home\/bin]$ .\/ldapbind -h <oid_hostname> -p <oid_ssl_port> -U 1 -D cn=orcladmin -w <pwd><\/p>\n

5. Start the OC4J service [oracle_home\/opmn\/bin]$.\/opmnctl startproc process-type=OC4J_SECURITY<\/p>\n

6. Unable to come up, once again stop all services in osinfra, and truncate the ods_process table and start the process again but no luck.<\/p>\n

I did some more workarounds but no luck.<\/p>\n

Finally I replace the old backup of osinfra folder and try to bring up the services one by one.<\/p>\n

1. Started the OID service but ldapbind not happening. Executed the action plan in this metalink 558296.1<\/p>\n

Now ldapbind happen smoothly but again OC4J service not coming up after replaces the backup.<\/p>\n

2. Tried to reset the IASpassword but it\u2019s failed.<\/p>\n

After long workaround, we come to know the solution for this issue.<\/p>\n

3. resetiaspassword is not working because is expecting LBR working and we get a little clue about this issue and we tried to bind with LBR hostname but its failed.<\/p>\n

4. Verified the LBR hostname in \/etc\/hosts file and we surprised how LBR entry get missed.<\/p>\n

5. Added LBR hostname in \/etc\/hosts and then ping\/ldapbind was working<\/p>\n

Finally, executed resetiaspasswd too and OC4J_SECURITY started as expected.<\/p>\n

I hope this will hep you. \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
