SPILL (Transfer Data to RXX) › When to Use Inactive Recovery

When to Use Inactive Recovery

With an Inactive Recovery File and when the console message DB00308 occurs, log blocks are spillable and a spill should be done. A spill may not be successful at other times for the following reasons:

• The Log Area may have data, but due to an active transaction, no blocks are spillable. The utility terminates processing the utility job step and takes no action concerning the Recovery File.
• A spill may already be in progress. In this case, a message so indicates and the utility terminates processing the utility job step and takes no action concerning the Recovery File.
• The Log Area might be empty. In this case, a message indicates the empty condition, and the utility continues to the next function without error and no action concerning the Recovery File.

Note: When using inactive recovery (that is, NO specified for the MUF startup option LOGRCV) and checking for spillable data based upon the LOGSPILL percentage, CA Datacom/DB presumes that the portion of the Log Area (LXX) that contains pipelined index and/or data need not be spilled when determining the number of blocks spillable. This allows a spill option to reduce index/data I/O when preparing for a spill.
