When you setup the Content Collector DB2 Textsearch feature you might experience the following erorr while the DB2TS service is starting.

IQQG0181E The constructor AFUCTOR4EMAIL initialization process failed. Error details: AFUI0020E The plain text password could not be encrypted and saved to the file ‘C:\IBM\SQLLIB\db2tss\plugins\pw.txt’

In this case it seems that you forgot to copy the Masterkey.txt file from the Content Collector Server installation, stored unter ContentCollector\cmts to the following directories on you Content Manager 8 EE server.

You need to copy it into the DB2 instance db2tss folder e.g. C:\Program Files\IBM\SQLLIB\db2tss

And into the ContentCollector_DB2TS_Support folder.
