Placing journal receivers in a different disk pool from the journaled objects may prevent performance bottlenecks.
Before you place the journal receiver in a library basic disk pool, you must first create the library for the journal receiver in the disk pool.
You can only place a journal receiver in an independent disk pool if the independent disk pool is library capable. If you are placing the journal receiver in a switchable independent disk pool, you must place it in the same disk pool group as the journal and the object you are journaling. Manage disk units in disk pools has more information about disk pools. The Independent disk pools topic has detailed information about independent disk pools.
If you are creating the journal receiver with the Create Journal Receiver (CRTJRNRCV) command, you can use the ASP parameter to allocate storage space for the journal receiver in a different disk pool (ASP) than the library to which you assigned the journal receiver. Do this only if the disk pool is a basic nonlibrary disk pool.
