Running IDMSDBAN fails with condition code 4 and message:
598526 - PAGE 1/9549926 COMPUTED SPACE AVAILABLE NOT EQUAL TO PAGE HEADER SPACE AVAILABLE
Release : All
Component : CA IDMS/DB
The error indicates the space calculated to be available on the indicated database page is not equal to the available space, as indicated by the SR1 record for the page.
The available space is calculated to be the page size minus the space used for the footer, the line indexes, and the data.
More information may be available by turning on optional bit 194 by specifying #DEFOPTF OPT00194 in the RHDCOPTF module. Create a RHDCOPTF module only for the use of this IDMSDBN1 step.
0194 Scan free space in IDMSDBN1. Issue DC598502 if any non-zero values are detected
The space available error does not indicate there is any broken chain and will not cause any error during normal processing.
Depending on the size of the difference it could cause records targeting to that page may not fit, and will overflow to a page with sufficient space.
The space available on the header will be corrected the next time an unload/reload is performed.
