SAP IDM 8.0 PATCH2 ERROR : util-functions sqlplus command not found

Hi experts,

We just tried to apply the Patch2 for IDM8.0 and when i start with the databse after changing as always the include file etc...., I launch the mxmc-update.sh i have this message error " ./util-functionsh line 76 sqlplus: command not found "

We did not changed any configuration after the first installation of the IDM 8.0 so the PATH and environment variable and the JDBC are fine.

We use Oracle as Database/Linux

any one have any ideas about this problem ?
