Products

• CA Workload Automation AE
• CA Workload Automation AE - System Agent (AutoSys)

Issue/Introduction

When performing a silent install of the Workload Automation R12 System Agent to be used with AutoSys, it is failing with the following error...

Exit Code: 1
Invalid key size for the algorithm
:
Status: FATAL ERROR
Additional Notes: FATAL ERROR - "Post-Install: Creation of encryption key failed"

Environment

Release : 12.0

Component : Workload Automation System Agent

Resolution

If the install properties file has AUTOSYS_MODE=true, the cipher algorithm will always be AES. The install will fail with the error above if you have AUTOSYS_MODE=true but a DES is specified for the STRONG_ENCRYPTION_KEYGEN parameter. When the agent is to be used with AutoSys, the STRONG_ENCRYPTION_KEYGEN parameter value must be an AES encryption key.
