Create/Edit Table (with advanced options)up to 255 concurrent update transactions for any data block, depending on theavailable space in the block.Free Lists - Lists: Number of free lists for each of the free list groups for the table. Thedefault and minimum value for this parameter is 1, meaning that each free list groupcontains one free list.Free Lists - List Groups: Number of groups of free lists for the table. The default andminimum value for this parameter is 1. Oracle uses the instance number of RealApplication Clusters instances to map each instance to one free list group.Buffer Pool: means to use the Oracle Database default. KEEP means toput blocks from the segment into the Keep buffer pool; maintaining an appropriatelysized Keep buffer pool lets Oracle retain the database object in memory to avoid I/Ooperations. RECYCLE means to put blocks from the segment into the Recycle pool; anappropriately sized Recycle pool reduces the number of objects whose default pool isthe Recycle pool from taking up unnecessary cache space.Logging: means to use the Oracle Database default. ON means that thetable creation and any subsequent direct loader (SQL*Loader) and direct-path INSERToperations against the table, partition, or LOB storage are logged in the redo log file.OFF means that these operations are not logged in the redo log file.Partitioning tabSpecifies partitioning options for a partitioned table, which is a table that is organizedinto smaller and more manageable pieces called partitions. SQL queries and DMLstatements do not need to be modified in order to access partitioned tables; however,after partitions are defined, DDL statements can access and manipulate individualspartitions rather than entire tables or indexes. Also, partitioning is entirely transparentto applications.Partition By: The type of partitioning: RANGE partitions the table on ranges of valuesfrom the column list (which for an index-organized tablet must be a subset of theprimary key columns of the table); HASH partitions the table using the hash method(rows assigned to partitions using a hash function on values found in columnsdesignated as the partitioning key); LIST partitions the table on lists of literal valuesfrom column (useful for controlling how individual rows map to specific partitions).Available: Lists the columns whose values are available to be used in assigning rowsto partitions.Selected: Lists the column whose values are to be used in assigning rows to partitions.To add a column to the partitioning definition, select it in Available Columns and clickthe Add (>) icon; to remove a column from the partitioning definition, select it inSelected Columns and click the Remove (>) or Remove All (
Create/Edit Table (with advanced options)Tablespaces: Available and Selected tablespaces for storage of the data in asubpartition.Subpartition Templates: Specifications (subpartition templates) to control theplacement of rows in each subpartition. Click the Add (+) icon to add a subpartitiontemplate that is appropriate for the subpartition type.Subpartition Details: For each subpartition template, specify a name and (if relevant)a value or set of values that is appropriate for the subpartition type.Storage: Enables you to specify a tablespace for the subpartition.Partition Definitions tabDefines each partition for a partitioned table. The options depend on the partitiontype, and might include the following.Partitions: Specifications to control the placement of rows in each partition. Click theAdd (+) icon to add a partition specification that is appropriate for the partition type.Partition Details: For each partition specification, specify a name and (if relevant) avalue or set of values that is appropriate for the subpartition type.Storage: Enables you to specify a tablespace for the partition.Subpartitions: Enables you to specify subpartition information.Index Organized Properties tabSpecifies options for an index-organized table, which is a table in which the rows,both primary key column values and nonkey column values, are maintained in anindex built on the primary key. Index-organized tables are best suited for primarykey-based access and manipulation.PCTTHRESHOLD: The percentage of space reserved in the index block for anindex-organized table row; must be large enough to hold the primary key. All trailingcolumns of a row, starting with the column that causes the specified threshold to beexceeded, are stored in the overflow segment. PCTTHRESHOLD must be a value from1 to 50; the default is 50.Key Compression: If this option is checked, key compression is enabled, whicheliminates repeated occurrence of primary key column values in index-organizedtables. In the box to the right of this field, you can specify the prefix length, which isthe number of prefix columns to compress. (This value can be from 1 to the number ofprimary key columns minus 1; the default prefix length is the number of primary keycolumns minus 1.)Include Column: Column at which to divide an index-organized table row into indexand overflow portions. The primary key columns are always stored in the index. TheInclude Column can be either the last primary key column or any non-primary-keycolumn. All non-primary-key columns that follow the Include Column are stored inthe overflow data segment.Mapping Table: If this option is checked, SQL Developer creates a mapping of local tophysical ROWIDs and store them in a heap-organized table. This mapping is neededin order to create a bitmap index on the index-organized table. If the index-organizedtable is partitioned, then the mapping table is also partitioned and its partitions havethe same name and physical attributes as the base table partitions.Overflow: Specifications for the overflow segment. The options are the same as for theStorage Options tab.Dialog Boxes for Creating/Editing Objects 3-15
