Overview › Product Resource Allocation
Product Resource Allocation
Typically, two sets of resources are allocated to bring a product into use.
- The first set is a collection of disks owned by a user ID defined for one specific product and one specific product release. The ID exists just to own the disk space. It is defined as a NOLOG user ID.
- The second set is disk space allocated to house and run the product. A server-based product requires a server user ID which accepts requests and delivers services. It may employ worker virtual machines so it can offload function which can run in parallel. It may employ administration user IDs, like a tape librarian virtual machine, to manage and control the server function. Another type of product is a utility product. It does not have a server virtual machine. The product just supplies function executed directly by an end user. A utility product may just need disk space to hold the utility code.
The first set of resources is allocated during the Product Installation steps. The second set is allocated during each deployment of a product. When VMFINS INSTALL with the PLAN option is executed, a PLANINFO file is generated to document resource requirements for both sets of resources.
You may retrieve the resource requirements for both sets of resources directly from this PLANINFO file, or you may use the VMALLOC command tool to extract the information for you. VMALLOC may be configured to call CA VM:Secure or CA VM:Director if you use either product at your site.
