REST Interface
• ORAchk and EXAchk include full REST support, allowing invocation & query over HTTPS
• Oracle REST Data Services (ORDS) is included within the install
• To enable REST:
1. Start ORDS:
2. Start the daemon, using the -ords option:
• Start a full health check run by accessing the URL: https://<host>:7080/ords/tfaml/orachk/start_client
• Run specific profiles: https://<host>:7080/ords/tfaml/orachk/profile/<profile1>,<profile2>
• Run specific checks: https://<host>:7080/ords/tfaml/orachk/check/<check_id>,<check_id>
• Any request will return a job id, which can then be used to query:
– Status: https://<host>:7080/ords/tfaml/orachk/status/<job_id>
– Download result: https://<host>:7080/ords/tfaml/orachk/download/<job_id>
–ordssetup
-d start -ords
The standalone ORDS setup feature utilizes file based user authentication and is provided solely for use in test and development environments.
For production use, the included orachk.jar and ords.war should be deployed and configured.

Remote node connection without passwordless SSH
• ORAchk/EXAchk will:
1. Prompt for remote node password
2. Login to remote node and generate private and public key pair on remote node
3. Copy contents public key into the .ssh/authorized_keys file of remote node and delete the public key
from remote node
4. Copy private key of remote node into local node and use as identity file to make future connections
• Alternatively you can provide the private key file yourself
Run:
E.g.:
• This will generate the following key pair in the $HOME/.ssh/ directory:
– id_dsa.myhost67.root (private key / Identity file)
– id_dsa.myhost67.root.pub (Public key)
Confidential – Oracle Internal/Restricted/Highly Restricted 9
ssh-keygen -f $HOME/.ssh/id_dsa.host.user -N ''
ssh-keygen -f $HOME/.ssh/id_dsa.myhost67.user -N ''

– Once the zip file is encrypted, the original zip and directory will
be deleted
• To decrypt a zip use:
Confidential – Oracle Internal/Restricted/Highly Restricted 15
–profile dba -encryptzip
–decryptzip <zip_filename>
The encrypt/decrypt feature is only supported on Linux and Solaris platforms.
