Change Continuous Access Journal options used by journals

Most Continuous Access Journal pair operations are performed on multiple pairs. This is done
using journals. You can change the following options that affect the pairs in journals:
Inflow Control—allows you to restrict the inflow of data to allow other journals with higher
priority data unrestricted inflow
Data Overflow Watch—establishes a timeout period
Use of Cache—which enables using store journal data in the cache on the secondary system
Prerequisite information
Please be aware of the following when changing journal options:
Journal options must be changed on both systems, primary and secondary.
To change journal options, one of the following conditions must be satisfied:
- The attribute of the journal is Initial.
- The status of the journal in the mirror is one of the following:
◦ Initial
◦ Stopped
Hold(Failure)
◦
When one journal uses multiple mirrors, whether you can select Change Journal Option
depends on the status of the journal whose mirror is not in Hold, Holding or Hold(Failure)
status. For example, if mirrors in the journal are in the Hold and Active status, you can not
change the journal option. If mirrors in the journal are in the Hold and Stopped status, you
can change the journal option.
When changing options for multiple journals, you can leave some options unchanged by
entering or selecting no value. If you specify a value, it is applied to the selected journals.
