Hi, I was trying to convert a library in OA database to CDB through command line, using the following command. oa2cdb -lib TEST_LIB -cdslibpath /home/username/cds.lib -cdblibpath / home/username/CDBLIB/ -tech /home/username/TECHLIB/tsmcN45 In the cds.lib file, the library TEST_LIB is defined. The folder CDBLIB is newly & already created. It gives the following errors after execution of the above command: *WARNING* envGetVal: Could not find variable 'dbStatCacheOn' in tool[.partition] 'cdba'. *WARNING* envGetVal: Could not find variable 'dbInstNamingGlobalInc' in tool[.partition] 'cdba'. ERROR (OACDB-136): The -cdblibpath option cannot be used because the CDB version of library "TEST_LIB" already exists. Type "oa2cdb -h" for help on syntax and usage. INFO (OACDB-820): oa2cdb translation failed. How to get rid of this error? Thanks & Regards, Murali RC
