| And what is your question? All you gave is facts. This seems to be a ESDS dataset, which is in fact not automatically recoverable. How about changing it to a KSDS? |

Two things.....
What gives you the idea that recovery is being done?
What gives you the idea that this file is non-recoverable? |

Experts,
Using CEDC transaction i found that RECOVERY parameter in FCT was set to "Backoutonly", so the file i was working with, is a recoverable resoure. That is why backout was applied.
Explanation for Backput parameter is given below.
RECOVERY(BACKOUTONLY) - If you specify RECOVERY(BACKOUTONLY), CICS provides backout recovery only, writing only before-images to the system log.
Thaks for all your replies.
Thanks,
Ravikumar. |
