Rolling back the scenario deleting folder hotfix/10.7.0-HF10 Hotfix 10.7.0-HF10 was rolled back successfully


and the hotfix is not applied

Cause

The hotfix installer checks through the jars that are present for versions that do not fit with it it's permitted range if a mismatch is found the hotfix does not apply.

The check is done by looking at the Bundle_version value in the META-INF\MANIFEST.MF file in the existing jars for hf10 teh range that is acceptable is 10.7.0.45 -> 10.7.0.98.

In this case one of the reported versions was 10.7.0.0_sp

Environment

APM 10.7 on Linux

Resolution

Used the following shell script to help identify problem jar file in the <EM_HOME>/product/enterprisemanager/plugins folder

for i in `ls com.ca*jar com.wily*jar`
do
echo $i
jar xf $i META-INF/MANIFEST.MF
grep undle-Vers META-INF/MANIFEST.MF
rm META-INF/MANIFEST.MF
done


This identified fileĀ  com.wily.intrsocope.em.client_10.7.0.jar was the cause and this had come from a test fix - replaced with GA version and installer ran through ok
