Export and Import of mappings/process flows etc

Question

Hi,
We have a single repository with multiple projects for DEV/UAT and PROD of the same logical project. This is a nightmare for controlling releases to PROD and in fact we have a corrupt repository as a result I suspect. I plan to split the repository into 3 separate databases so that we have a design repos for DEV/UAT and PROD. Controlling code migrations between these I plan to use the metadata export and subsequent import into UAT and then PROD once tested. I have used this successfully before on a project but am worried about inherent bugs with metadata export/imports (been bitten before with Oracle Portal). So can anyone advise what pitfalls there may be with this approach, and in particular if anyone has experienced loss of metadata between export and import. We have a complex warehouse with hundreds of mappings, process flows, sqlldr flatfile loads etc. I have experienced process flow imports that seem to lose their links to the mappings they encapsulate.
Thanks for any comments,
Brandon

This should do the trick for you as it looks for "PARALLEL" therefore it only removes the APPEND PARALLEL Hint and leaves other Hints as is....
#set current location
set path "C:/TMP"
# Project parameters
set root "/MY_PROJECT"
set one_Module "MY_MODULE"
set object "MAPPINGS"
set path "C:/TMP
# OMBPLUS and tcl related parameters
set action "remove_parallel"
set datetime [clock format [clock seconds] -format %Y%m%d_%H%M%S]
set timestamp [clock format [clock seconds] -format %Y%m%d-%H:%M:%S]
set ext ".log"
set sep "_"
set ombplus "OMBplus"
set omblogname $path/$one_Module$sep$object$sep$datetime$sep$ombplus$ext
set OMBLOG $omblogname
set logname $path/$one_Module$sep$object$sep$datetime$ext
set log_file [open $logname w]
set word "PARALLEL"
set i 0
