You can simply produce an ASH report, which contains both the current active session data from the V$ACTIVE_SESSION_HISTORY view as well as the historical active session data stored in the DBA_HIST_ACTIVE_SESS_HISTORY view The ASH report shows you the SQL identifier of SQL statements, object information, session information, and relevant wait event information You can produce an ASH report by simply going to the OEM Database Control, or by running an Oracle-provided script In fact, Oracle provides you with two ASH-related scripts, as follows: The ashrptsql script produces an ASH report for a specified duration for the default database The ashrptisql script produces the same report as the ashrptsql script, but lets you specify a database instance Actually, the ashrptsql script defaults the DBID and instance number to those of the current instance, and simply runs the ashrptisql script.

------------------------------

Both of the preceding described scripts are available in the $ORACLE_HOME/rdbms/admin directory Here s how you get an ASH report for your instance: SQL> @ORACLE_HOME/rdbms/admin/ashrptsql You can then look at the ASH report, which is placed in the directory from which you ran the ashrptsql script 18 explains a typical ASH report, in the section titled Producing an ASH Report..

For Oracle to use stored outlines consistently, you need to turn the USE_STORED_OUTLINES parameter on by setting its value to TRUE. By doing this, you re ensuring that the CBO is stable and won t change its plans over time. If the system tablespace is being filled up with too many stored outlines, you can drop some of the outlines by using the DBMS_OUTLN.DROP_UNUSED procedure. This procedure, which doesn t need any parameters, removes all literal SQL outlines from the OUTLN tables. The DBMS_OUTLN_EDIT.CREATE_EDIT_TABLES procedure. creates tables in a user s schema if you need to edit any private outlines. The DBMS_OUTLN_EDIT.DROP_TABLES procedure enables you to drop the outlined editing tables.

So far in this chapter, you ve looked at ways to improve performance how to make the database go faster. Sometimes, however, your problem is something much more serious: the database seems to have stopped all of a sudden! The following sections describe the most important reasons for a hanging or an extremely slow-performing database, and how you can fix the problem ASAP. One of the first things I do when the database seems to freeze is check and make sure that the archiver process is doing its job. The following sections describe the archiver process.

Stratum 1 primary timeservers: These could be dedicated timeservers such as Symmetricom s NTS-200 unit shown in Figure 5-1 or multipurpose Unix servers that integrate a primary reference clock. Stratum 2 or higher devices: These are the local masters or impersonators. Routers, switches, and various operating system servers that do not support primary reference clocks, including a Windows 2003 server without any third-party software to turn it into a primary timeserver, could be used in that capacity. That s provided they have the option of being configured as master devices. The net effect of utilizing this option without the presence of dedicated timeservers is that time synchronization throughout the network is possible but without accurate reference to UTC.

The DBMS_SPACE package is useful for finding out how much space is used and how much free space is left in various segments such as table, index, and cluster segments. Recall that the DBA_FREESPACE dictionary view lets you find out free space information in tablespaces and data files, but not in the database objects. Unless you use the DBMS_SPACE package, it s hard to find out how much free space is in the segments allocated to various objects in the database. The DBMS_SPACE package enables you to answer questions such as the following: How much free space can I use before a new extent is thrown How many data blocks are above the high-water mark (HWM) The DBA_EXTENTS and the DBA_SEGMENTS dictionary views do give you a lot of information about the size allocated to objects such as tables and indexes, but you can t tell what the used and free space usage is from looking at those views. If you ve been analyzing the tables, the BLOCKS column will give you the HWM the highest point in terms of size that the table has ever reached. However, if your tables are undergoing a large number of inserts and deletes, the HWM isn t an accurate indictor of the real space used by the tables. The DBMS_SPACE package is ideal for finding out the used and free space left in objects.
