CA Workload Automation Agent for AIX 32-bit
Version R11.3, Service Pack 1, Maintenance Level 1, Build 413
The spool file contained the following error
cybspawn: unable to obtain the message queue ID. errno:13 Reason:The file access permissions do not allow the specified action.
The problem was due to the fact that the /opt/CA did not have valid permissions for the world
drwxr-x--- 6 root system 256 Apr 12 18:12 /opt/CA
The ‘/opt/CA’ is a folder and it needs execute permission to be browseable
x bit for directory is also called as search bit. Actually, it enables you to access the inodes of the files listed inside the folder. So if you want to access spool folder then you must have search access on every parent folder.
Granting execute permission on /opt/CA resolves this problem
chmod 755 /opt/CA
