20 CHAPTER 1 ■ INSTALLING, UPGRADING, AND MANAGING CHANGE■Note Your database upgrade may take a long time since the database will collect optimizer statisticsfor any dictionary tables that are missing statistics or whose statistics were significantly changed duringthe upgrade. You can speed up the upgrade process by gathering statistics for these tables by using theDBMS_STATS.GATHER_DICTIONARY_STATS procedure before starting the upgrade.1. Log in as the owner of the Oracle 11.1 release Oracle home directory, and copy theutlu111.i sql file from the $ORACLE_HOME/rdbms/admin directory to another directorysuch as /tmp.2. Log in as the owner of the Oracle home directory of the database you want to upgrade,and run the utlu111.i sql script (from the /tmp directory, where you copied it to) to getthe pre-upgrade information such as the necessary initialization parameter changes,tablespace space requirements, and so on. Spool the results of the script execution soyou can review the output later. For example, the following is a run of the utlu111i.sqlscript on one of our own systems:SQL> spool upgrade.logSQL> @utlu111i.sqlOracle Database 11.1 Upgrade Information Utility 03-23-2007 13:36:14.**********************************************************************Database:**********************************************************************--> name: ORCL--> version: 10.2.0.1.0--> compatible: 10.2.0.1.0--> blocksize: 8192.**********************************************************************Tablespaces: [make adjustments in the current environment]**********************************************************************--> SYSTEM tablespace is adequate for the upgrade..... minimum required size: 593 MB....
