TimesTen stores metadata (information about the contents of your database) in system tables in your database.
Your applications can read the system tables, but it cannot update the system tables. If your application defines a table with the same name as a system table, then your application can read a system table by prefixing the system table name with SYS
. For example, SELECT * FROM SYS.TABLES
selects rows from the TABLES
system table.
Information specific to system tables:
Locks acquired by users on system tables may prevent others from defining data or executing the SQLPrepare
ODBC function or the Connection.prepareStatement
JDBC method.
The last character in name columns is always a space. Therefore, while the column length for name columns is 31, the maximum object name length is 30.
On 64-bit systems, TimesTen system tables declare certain fields as data type TT_BIGINT
. When retrieving these columns with an ODBC program, the application must bind them using SQL_C_BINARY
. For information about SQL_C_BINARY
, see ODBC documentation.
Note:
Some tables contain columns namedSYS
number
. Because these columns contain values used internally by TimesTen, they are not documented in this chapter.Several system tables and views in TimesTen are reserved for internal or future use. These tables are not described in detail in this chapter:
PL/SQL system tables are reserved for internal use. Use the PL/SQL system views instead. PL/SQL system tables in TimesTen are:
If PL/SQL is enabled in your database, there are tables and views created for the operation of the package UTL_RECOMP
:
These PL/SQL system views are reserved for internal use:
By default PUBLIC
has SELECT
privileges on various system tables and views and EXECUTE
privileges on various PL/SQL objects. You can see the list of objects by using this query:
SELECT * FROM sys.dba_tab_privs WHERE grantee='PUBLIC';
The ADMIN
or SELECT ANY TABLE
privilege is required to access other system tables and views.
The ALL_ARGUMENTS
view lists the arguments of the procedures and functions that are accessible to the current user.
SYS.DBA_ARGUMENTS
lists the arguments of the procedures and functions that are available in the database. It has the same columns as ALL_ARGUMENTS
.
SYS.USER_ARGUMENTS

The MONITOR
table stores information about system performance. It contains a single row with statistics about certain events. For many columns, statistics are gathered starting from the time the database is loaded into memory and statistics are cleared when the database is unloaded from memory. With a ramPolicy
of manual
or always
, the database remains in memory when there are no application connections.
For some columns, statistics are gathered as needed. TimesTen does not gather statistics from the time of the first connection for these columns:
PERM_ALLOCATED_SIZE
PERM_IN_USE_SIZE
TEMP_ALLOCATED_SIZE
LAST_LOG_FILE
REPHOLD_LOG_FILE
REPHOLD_LOG_OFF
FIRST_LOG_FILE
CHECKPOINT_BYTES_WRITTEN
For most columns, the MONITOR
table is reset whenever there are no connections to the database. TimesTen does not reset the values of the following columns, even when there are no connections to the database:
PERM_ALLOCATED_SIZE
PERM_IN_USE_SIZE
TEMP_ALLOCATED_SIZE
LAST_LOG_FILE
REPHOLD_LOG_FILE
REPHOLD_LOG_OFF
FIRST_LOG_FILE
TimesTen frequently updates information in the MONITOR
table. To prevent these updates from slowing down the system, they are not protected by latches. Hence values in the MONITOR
table are not absolutely accurate. They can be used as a reliable indication of activities in the system.
The PLAN
table contains the execution plan that the TimesTen query optimizer prepares after an application calls ttOptSetFlag
. See "Generating a query plan" and "Modifying plan generation" in Oracle TimesTen In-Memory Database Operations Guide.
The execution plan includes the operation performed at each step and the table or index that it references.
