I'm probably going to [re]start a blog just because of this issue. HUGE
thanks goes out to Brian Pardy for his help on this and writing a great blog
about recreating (modifying) the Oracle Wallets to get rid of the demo certs.

First, this "adventure" started with laying down EM 12.1.0.5 vanilla install.
Due to the numerous java vulnerabilities identified in the last 12-15
months, there have been several patches that browser makers have applied and
pushed out. These browser updates effectively "broke" the ability to peruse
EM 12c (the console) and generated numerous Metalink documents.

The error was:

https://host:port/console generates Server has a weak ephemeral
Diffie-Hellman public key. The https://host:port/em server seemed to work ok.

Secondly, after trying to patch this problem away using the CPU 2015 Patch
Guide (Applying Enterprise Manager 12c Recommended Patches (Doc ID
1664074.1), the brokeness of the EM 12.1.0.5 install only increased.

Then, I ran across Brian Pardy's blog post about setting the Oracle wallets
and getting rid of the demo certs and generating new certificates HERE:

https://pardydba.wordpress.com/2015/03/03/step-by-step-configuring-third-party-ssltls-certificates-in-em12c-r4/

(I skipped the section "Creating Wallets for each agent" about generating
certificates for each agent for now as that would require CSRs for each host
where an agent will be running. I might come back to that though.

So, here's the steps that got me to a perfectly useable EM 12.1.0.5
installation. I'm going to attempt the October 2015 Patching guide again now
but at least I know I can flash back to this structure and it be useable.
In a nutshell, when laying down EM 12.1.0.5 vanilla install today, you REALLY
should get 1024 or 2048 bit keys, appropriate Trusted/Issuing/User
Certificates, and patch Weblogic.

Steps (at a high level) - the only steps I came up with were the 3 Weblogic
Patching steps to support Keys longer than 512 bits (steps 16-18). This may
be messy but I formatted it with FIXED WIDTH and it shows up correctly in
draft mode.

01. Install EM 12.1.0.5 Software Browse
to https://host:port/console - should receive error due to browser updates.
If not, you don't have the latest updates.
02. Backup installed directories:
- agent dir $ORACLE_BASE/product/agent12c
- middleware dir $ORACLE_BASE/product/middleware
- instance dir $ORACLE_BASE/product/gc_inst
- swlib dir $ORACLE_BASE/product/swlib
03. Create an Oracle Wallet
https://pardydba.wordpress.com/2015/03/03/step-by-step-configuring-third-party-ssltls-certificates-in-em12c-r4/
04. Generate 2048 bit Keys inside wallet
https://pardydba.wordpress.com/2015/03/03/step-by-step-configuring-third-party-ssltls-certificates-in-em12c-r4/

05. Generate certificate signing request (CSR) for the created wallet
https://pardydba.wordpress.com/2015/03/03/step-by-step-configuring-third-party-ssltls-certificates-in-em12c-r4/
06. Send CSR to Signing Authority
https://pardydba.wordpress.com/2015/03/03/step-by-step-configuring-third-party-ssltls-certificates-in-em12c-r4/
07. After receiving certs import them into the wallet

$OMS_HOME/bin/emctl secure add_trust_cert_to_jks -trust_certs_loc
$ORACLE_WALLET_LOC/issuing.cer -alias <choose_an_alias_name> -password welcome
