Oracle 11g Training on 29JAN1010

Posted on 29-Jan-2010 By Admin No Comments on Oracle 11g Training on 29JAN1010

-SERVICE_NAMES = INSTANCE_NAME + DB_DOMAIN

-GLOBAL DATABASE NAME should be same as SERVICE_NAMES

-If system ts is LMT then temporary tablespace is required.

-if system ts is lmt then no dmt can be created in db.

-When system ts is LMT then undo tbs is also must.

-1 tbs can have max 1022 dbfs.

-1 database can have max 65533 dbfs.

-1 db can have unlimited tbs. but max dbf per db is 65533 so max 65533 tbs allowed.

-autoextend on is not good for UNDO and TEMP files.

-extent mgmt local will replace all manual extent parameters.

-segment space mgmt auto will ignore pctfree, pctused, freelists, freelist groups.

-the min extent size for LMT with autoallocate is 64K

-bigfile tbs are always LMT.

-temp tbs are by default LMT with uniform size 1M

-lsnrctl services listener_testdb will give all db service listing and cumulative information for how many connections are made, rejected for that dbservice from that listener.

– dynamic service registration of database services to listener is there since oracle 8i.
