Running the System Allocator (SALO)

Before you can run the system allocator (SALO), you must have:

There are two different ways you can run SALO, depending on whether you run SIP Stage I, or both SIP Stages I and II.

To Run Only SIP Stage I

  1. Code EXPRS=S on the SIP GENSIP macro.
  2. Assemble the Stage I deck.
  3. Run the JCL that was produced from SIP Stage I.

To Run Both SIP Stages I and II

  1. SALO is compiled automatically, link-edited, and executed during Stage II.

When SALO runs successfully, it produces the system allocator (SAL) table and the program allocator table (PAT), which are written to disk as partitioned data sets.
