Journal receiver calculator

Estimate the size of the journal receiver manually

Use the journal receiver calculator to estimate the size of your journal receiver. This calculator makes the following assumptions:

You are journaling database physical files.
You are journaling after-images only.
You are using a single journal receiver for an entire day's transactions.
You are journaling database physical files only. It does not include estimates for access path journaling, integrated file system objects, data areas, data queues, or user-created entries.
You are not minimizing entry-specific data (MINENTDTA parameter) for the files.

As an alternative to the calculator, you can use the manual method to estimate the size of the calculator.

Enter the average record length of files to be journaled:	(bytes)
Enter the number of transactions for a day:

Select fixed-length options you are using:
	Job name (JOB) User profile (USR) Program name (PGM) Program library (PGMLIB)	System sequence number (SYSEQ) Remote address (RMTADR) Thread identifier (THD) Logical unit of work (LUW) Transaction identifier (*XID)
