Installed SQL*Plus Scripts
There are SQL*Plus scripts that are installed with TimesTen.
-
cacheCleanUp.sql
: This script drops Oracle Database objects such as change log tables and triggers used to implement autorefresh operations for TimesTen Classic. This script is used when a TimesTen Classic database containing cache groups with autorefresh is unavailable because the TimesTen Classic system is offline, or the database was destroyed without dropping its cache groups with autorefresh. Run this script as the cache administration user. Provide the host name of the TimesTen Classic system and the TimesTen database (including its path) as arguments. See Dropping Oracle Database Objects Used by Cache Groups with Autorefresh.This example uses the
cacheCleanUp.sql
script for a TimesTen Classic system. ThescaleoutCacheCleanup.sql
script runs in the same manner for TimesTen Scaleout, except that it requires the grid name and database name as input parameters.% cd timesten_home/install/oraclescripts % sqlplus cacheadmin/orapwd SQL> @cacheCleanUp "sys1" "/disk1/databases/database1" *****************************OUTPUT************************************** Performing cleanup for object_id: 69959 which belongs to table : CUSTOMER Executing: delete from tt_07_agent_status where host = sys1 and datastore = /disk1/databases/database1 and object_id = 69959 Executing: drop table tt_07_69959_L Executing: drop trigger tt_07_69959_T Executing: delete from tt_07_user_count where object_id = object_id1 Performing cleanup for object_id: 69966 which belongs to table : ORDERS Executing: delete from tt_07_agent_status where host = sys1 and datastore = /disk1/databases/database1 and object_id = 69966 Executing: drop table tt_07_69966_L Executing: drop trigger tt_07_69966_T Executing: delete from tt_07_user_count where object_id = object_id1 **************************************************************************

cacheInfo.sql
: This script returns change log table information for all Oracle Database tables cached in a cache group with autorefresh, and information about Oracle Database objects used to track DDL statements issued on cached Oracle Database tables. This script is used to monitor autorefresh operations on cache groups and DDL statements issued on cached Oracle Database tables. Run this script as the cache administration user. You can alternatively use thettCacheInfo
utility.The following example runs the
cacheInfo.sql
SQL*Plus script.% cd timesten_home/install/oraclescripts % sqlplus cacheadmin/orapwd SQL> @cacheInfo.sql ***************** Database Information ********************* Database name: DATABASE1 Unique database name: database1 Primary database name: Database Role: PRIMARY Database Open Mode: READ WRITE Database Protection Mode: MAXIMUM PERFORMANCE Database Protection Level: UNPROTECTED Database Flashback On: NO Database Current SCN: 21512609 ************************************************************* *************Autorefresh Objects Information *************** Grid name: grid1 (7D03C680-BD93-4233-A4CF-B0EDB0064F3F) Timesten database name: database1 Cache table name: SALES.CUSTOMERS Change log table name: tt_07_96977_L Number of rows in change log table: 4 Maximum logseq on the change log table: 1 Timesten has autorefreshed updates upto logseq: 1 Number of updates waiting to be autorefreshed: 0 Number of updates that has not been marked with a valid logseq: 0 *************DDL Tracking Object Information *************** Common DDL Log Table Name: TT_07_DDL_L DDL Trigger Name: TT_07_315_DDL_T Schema for which DDL Trigger is tracking: SALES Number of cache groups using the DDL Trigger: 10 **************************** PL/SQL procedure successfully completed.

grantCacheAdminPrivileges.sql
: This script grants privileges to the cache administration user that are required to automatically create Oracle Database objects used to manage the caching of Oracle Database data when particular cache group operations are performed. This includes theTT_CACHE_ADMIN_ROLE
role that defines privileges on Oracle Database tables. Run this script as thesys
user. See Create Oracle Database Objects Used to Manage Data Caching.The following example for a non-autonomous Oracle Database grants the required SQL privileges to the
cacheadmin
user for cache operations in the Oracle database:@grantCacheAdminPrivileges.sql cacheadmin

For Oracle Autonomous Database Serverless with the Transaction Processing workload type, Step 16 output is as follows:
16. Checking if the cache administrator user has permissions on the default tablespace
No existing permission.
Oracle Autonomous Database automatically configures tablespaces. Therefore, this permission is not necessary.

checkAdminPrivileges.sql
: This script checks that the cache administration user has all of the necessary privileges (those that are provided when you run thegrantCacheAdminPrivileges.sql
script) that are required for cache operations. Run this script as the user that you want checked. If privileges are missing, you can either have thesys
user grant the missing privileges or run thegrantCacheAdminPrivileges.sql
script for this user. See The checkAdminPrivileges.sql Script.Use SQL*Plus on the Oracle Database system from an operating system shell or command prompt, and connect to the Oracle database instance as the user (in most cases, the cache administration user) that you want checked for privileges. The following example shows that the user has all of the required privileges.
SQL> @checkAdminPrivileges.sql **** Checking privileges for cache administrator user **** **** User has all privileges for a cache administrator user ****
The following example shows the output if you have missing privileges needed on an Oracle database:
SQL> @checkAdminPrivileges.sql **** Checking privileges for cache administrator user **** Missing CREATE OPERATOR Missing CREATE INDEXTYPE Missing CREATE CLUSTER Missing EXECUTE ON SYS.DBMS_LOCK Missing EXECUTE ON SYS.DBMS_DDL Missing EXECUTE ON SYS.DBMS_FLASHBACK Missing EXECUTE ON SYS.DBMS_LOB Missing SELECT on SYS.GV$LOCK Missing SELECT on SYS.GV$SESSION Missing SELECT on SYS.DBA_DATA_FILES Missing SELECT on SYS.V$DATABASE Missing SELECT on GV$PROCESS Missing UNLIMITED TABLESPACE Missing SELECT ANY TRANSACTION Missing table ARDL_CG_COUNTER **** User missing privileges. Missing privilege count: 15 ****

initCacheAdminSchema.sql
: This script grants a minimal set of privileges to the cache administration user and manually creates Oracle Database objects used to manage the caching of Oracle Database data. This includes theTT_CACHE_ADMIN_ROLE
role that defines privileges on Oracle Database tables. Run this script as thesys
user. See The initCacheAdminSchema.sql Script.In the following example, the Oracle database cache administration user name is
cacheadmin
.@initCacheAdminSchema cacheadmin

scaleoutCacheCleanUp.sql
: This script drops Oracle Database objects such as change log tables and triggers used to implement autorefresh operations for TimesTen Scaleout. This script is used when a TimesTen Scaleout database containing cache groups with autorefresh is unavailable because the TimesTen Scaleout system is offline, or the database was destroyed without dropping its cache groups with autorefresh. Run this script as the cache administration user. Provide the grid name and the TimesTen database name as arguments.The
scaleoutCacheCleanup.sql
script runs in the same manner for TimesTen Scaleout as thecacheCleanUp.sql
script does for TimesTen Classic.See Dropping Oracle Database Objects Used by Cache Groups with Autorefresh.
