Free Oracle Tool to Simplify Commonly Run Dictionary Queries

Question

(orastat has a very good 'Hot Blocks' query)
Hi,
My co-workers and I at Agilent Technologies have developed a
useful tool to simplify running common dictionary queries. It
runs on UX and requires that you be the "oracle" user. You can
download it from
http://dbamon.com/orastat
For example, if you wanted info about a certain table, you could
query DBA_TABLE, DBA_INDEXES. With our tool "orastat", you would
just run 'orastat -ti <OWNER>.<TABLE>. Example:
2002/01/13-09:09:17 orastat | oraver=8.1.6 oraver3=8.1 sqlcmd=sv
2002/01/13-09:09:17 orastat | ORACLE_SID=DBA ORACLE_HOME=/opt/oracle/product/8.1.6
2002/01/13-09:09:17 orastat | Version=2.23 Host=bigdog Company=agilent

Answer 1

If the application uses a single database session, you can also generate a SQLTrace file to analyse with tkprof by using either Oracle Enterprise Manager to turn on SQL Trace for the session, or use DBMS_MONITOR SESSION_TRACE_ENABLE(session_id, serial_num) - you then have to find the trace file on the datbaas eserver USER_DUMP_DEST and either read manually (the queries are easily visible) or use tkprof to analyze it Using Application Tracing Tools  Among other things tkprof can tell you the top resource consuming SQL statements.
