.<\/p>\n

    \nAt dbi services, we really like Lighty for Oracle, a tool which helps exploring performance statistics whether they originate from AWR (available only in Enterprise Edition with Diagnostic Pack option) or from Statspack (available via Standard Edition). As a matter of fact, we like it so much that we have became Orachrome Partner.<\/p>\n

    If you want to try it out for yourselves, there is a free trial here<\/a>. If you have Statspack installed (see spdoc.txt in ORACLE_HOME\/rdbms\/admin to install it), you can immediately use Lighty.<\/p>\n

    Let me show you how to install it. First, you have to define a connection (shortcut: Ctrl-A):<\/p>\n

    \"CaptureLighty001.PNG\"<\/a><\/p>\n

    It is a jdbc connection without the need to install anything else. You just need the listener host, port, and service:<\/p>\n

    \"CaptureLighty002.PNG\"<\/a><\/p>\n

    As you are on Oracel Standard Edition, you don’t have Diagnostic Pack nor tuning Pack.
    \nBut you have installed Statspack, and you will install L-ASH very soon:<\/p>\n

    \"CaptureLighty003.PNG\"<\/a><\/p>\n

    Now, you can install L-ASH as documented. But the goal of this post is to show what you can get it immediately. Go to the menu: Reports > DB Statistics > Past Activity (Statspack)
    \nYou can select a day and see the snapshots. The color bar immediately shows when the activity was high:<\/p>\n

    \"CaptureLighty004.PNG\"<\/a><\/p>\n

    Then you can choose the graphical equivalent for my preferred Statspack sections:
    \nTop Events:<\/p>\n

    \"CaptureLighty005.PNG\"<\/a><\/p>\n

    Top Segments (change the Statspack level to 7 for that):<\/p>\n

    \"CaptureLighty007.PNG\"<\/a><\/p>\n

    And of course Top SQL Statements:<\/p>\n

    \"CaptureLighty006.PNG\"<\/a><\/p>\n

    For each statement (click on its sql_id) you will have everything: SQL text, execution plan, statistics.
    \nIf you like the tool, it’s time to go further and install L-ASH so that you can mine from the Activity Viewer tab, which is the most valuable feature of Lighty for Oracle.<\/p>\n","protected":false},"excerpt":{"rendered":"
