How affect to db server if analyzing table and index every day ?

 Hi all,

   I used oracle version 9.2.0.4 on Unix

   If I need to compute size of objects in database and use this information to monitor how big is one table or index might be a candidate for moving or rebuilding in order to improve performance. 

   The first, I must run ANALYZE such: 

ANALYZE TABLE TEST.T2 COMPUTE STATISTICS;

   

   Or:

EXEC DBMS_STATS.gather_table_stats('TEST', 'T2');

   But I want ask just about analyze table object: If every day, I analyze some tables, this work affect to perfomance of DML ? About index, every week I scheduled shrink and analyze index.
