-===== Create database =====
-==== Windows ====
-  * open dsn admin
-  * Create a new dsn
-  * Select TimesTen Data manager
-  * Select the Data & logs path
-  * Configure some ops (if you want)
-  * create dsn
-  * Open cmd
-  * run ttenv.bat
-  * run ''"ttIsql InstanceName"''
-  * Create a user:
-<code sql>
-CREATE USER <USERNAME> IDENTIFIED BY <PASSWORD>;
-GRANT CREATE SESSION, CREATE TABLE TO <USERNAME> ;
-</code>
-Maybe you also must give that user
-Connect as the user:
-<code sql>
-connect "dsn=<INSTANCENAME>;uid=<USERNAME>";
-</code>
-==== Linux ====
-  * Login as the user that installed TimesTen
-  * cd to the "info" directory":
-<code>
-cd /home/timesten/TimesTen/tt1122/info

-  * edit ''sys.odbc.ini''
-  * Define a new DSN under "[ODBC Data Sources]" section
-<code>
-[ODBC Data Sources]
-test-ttdb=TimesTen 11.2.2 Driver
-</code>
-  * Define the settings of the new DSN under "new data source"

-Connect as the user:
-<code sql>

-</code>
-==== create a cache grid ====
-st of all, in the OracleDB run the following scripts as sysdba:
-<code sql>
-@initCacheGlobalSchema.sql
-@grantCacheAdminPrivileges.sql
-</code>
-Both are located on the TimesTen installation (//oraclescripts// folder).
-This time I use the user named on the TT db creation.
-Then create the grid on TimesTen:
-<code>
-call ttGirdCreate('GridName');
-call ttGirdNameSet('GridName');
-</code>
-=====Steps to remove Cache groups and Cache Grid from TimesTen and Oracle (Doc ID 836887.1)=====
-TimesTen side:
-<code>
-call ttGridDetach;
-call ttrepstop;
-DROP CACHE GROUP tester.writecache;
-DROP CACHE GROUP tester.dummy_cli;
-call ttGridDestroy('ttGrid');
-call ttCacheStop;
-</code>
-Oracle Side:
-<code>
-DROP USER cacheadm CASCADE;
-DROP USER tester CASCADE;
-DROP USER timesten CASCADE;
-DROP ROLE tt_cache_admin_role;
-DROP TABLESPACE cachegrid_tbl INCLUDING CONTENTS AND DATAFILES;
-DROP TABLESPACE cacheadmtblsp INCLUDING CONTENTS AND DATAFILES;
-</code>
-=====Steps to add a TimesTen node into an existing Cache Grid (Doc ID 842990.1)=====
-This assumes you already have a functioning Cache Grid with at least one TT node and one Oracle database.
-. Create the relevant users in the TimesTen datastore to be added to the Cache Grid. The datastore in the examples is called tt1121_2. Connect as the Instance Administrator user. This is assuming the Cache Admin user cacheadm and Oracle user tester are the same users / passwords that you created in previous TT nodes attached to the same grid, and hence do not need to be pre-created on Oracle again.
-<code>
-CREATE USER cacheadm IDENTIFIED BY cacheadmora;
-CREATE USER tester IDENTIFIED BY tester;
-GRANT CREATE SESSION, CACHE_MANAGER TO cacheadm;
-grant create any table to cacheadm;
-grant drop any table to cacheadm;
-grant admin to tester;
--- as a shortcut make the TT user an administrator
--- this isn't recommended anywhere else apart from for testing
- </code>
-. Run the following as the Cache Administrator on the Timesten datastore tt1121_2. This assumes the tester.writetab table has already been created on Oracle:
-<code>
-call ttCacheUidPwdSet('cacheadm','cacheadmora');
-call ttGridNameSet('ttGrid');
-call ttCacheStart;
-CREATE DYNAMIC ASYNCHRONOUS WRITETHROUGH GLOBAL CACHE GROUP tester.writecache
-FROM tester.writetab
-(a NUMBER NOT NULL PRIMARY KEY, b VARCHAR2(31));
-call ttrepstart;
-call ttGridAttach(1,'tt1121_2','mymachine',9992);
-</code>
-. Run the following as Instance Administrator on the Timesten datastore tt1121_2:
-<code>
-GRANT SELECT ON tester.writetab TO cacheadm;
-GRANT insert ON tester.writetab TO cacheadm;
-GRANT update ON tester.writetab TO cacheadm;
-GRANT delete ON tester.writetab TO cacheadm;
-</code>

-===== tt15105 =====
-Error sample:
-<code>

-connect "DSN=myinstance_tt";
-: User XXXX requesting database creation is not the instance administrator.  Please verify user id and password. Only the instance administrator can create a database.
-The command failed.
-Done.
-</code>
-The problem is that you're trying to access the instance WITHOUT being super admin (the one who installed the software).
-See the admin user with:
-<code>
-PS C:\TimesTen\tt1122_64\bin> .\ttStatus.exe
-TimesTen status report as of Mon Mar 23 18:42:23 2015

-Command>
-</code>
-===== No Oracle password =====
-This error is either in sqldeveloper or ttIsql:
-<code>
-No Oracle password found in connection.  This command requires a connection with an Oracle password.
-</code>
-The cache admin username MUST BE THE SAME as the oracle user tt admin.
-In sqldeveloper you must allow the creation of cache groups and fill the connection settings.
-===== TT5907 =====
-<code> 5907: The cache admin user id was not set before performing the operation.  Set the cache admin user id and password ei
-ther through the built-in procedure ttCacheUidPwdSet or the utility ttAdmin and try again.
-The command failed.
-</code>
-You must set the it all:
-<code>
-ttAdmin -cacheUidPwdSet -cacheUid cache_manager_user -cachePwd ThePassword myDSN
-</code>
-===== TT5002 / TT5051 =====
-<code>
-Warning  5002: Unable to connect to the cache agent for c:\timesten\DIVAPRE_TT; check agent status
-Warning  5051: Commit message to cache agent failed. Cache agent must be restarted
-</code>
-Start (or restart) the cache agent:
-<code>
-ttadmin -cacheStart myDSN
-ttadmin -cacheStop myDSN
-</code>
-===== TT5221 =====
-<code>
-: Oracle syntax error in OCIStmtExecute(): ORA-00907: missing right parenthesis rc = -1
-</code>
-While executing [[http://docs.oracle.com/database/121/TTREF/proced.htm#TTREF248|ttGridAttach]]:
-<code>ttGridAttach(currentNode, 'name1', IPAddr1, port1)</code>
-I found that ALL THE PARAMETERS need to be between single quotation mark!
-===== TT3344 =====
-Whole stack:
-<code>11:23:24.10 Err :    :  1344: 1670/0x14c6030: cacheGrid.c (10349): Member TT001: sbCGAttach failed at line 10193, errCode=3344 - TT3344: Error creating grid threads: cacheGridAPI.c (759): Member DIVAGRID_TT001_1 got error TT3401: P2P error: Failed to bind to socket
-</code>
-While executing [[http://docs.oracle.com/database/121/TTREF/proced.htm#TTREF248|ttGridAttach]]
-The combination ip:port must be FREE! (TT will bind that ip:port combo).
-Maybe you've tried early an attachment and the data are logged on the oracle side.
-You can see that info in a table matching TT_%_CGNODEINFO, search it:
-<code sql>
-select owner, object_name, object_type
-from dba_objects
-where object_name like '%CGNODEINFO%' order by 2;
-</code>
-And delete the data:
-<code sql>SELECT 'DELETE FROM ' || OWNER || '.' || OBJECT_NAME || ' ; '
-FROM dba_objects
-where object_name like '%CGNODEINFO%' ;
-commit;
-</code>
-(maybe you want to make a backup of the data).
-===== TT3316 =====
-Whole stack:
-<code>Command> CREATE DYNAMIC ASYNCHRONOUS WRITETHROUGH GLOBAL CACHE GROUP CACHEDUSER."aaaa"

-: Cache group definition mismatch among the members of the grid
-</code>
-Maybe you've tried early a definition of the cache group, maybe not with the same name but using the same table!!
-Drop it from Oracle.
-You can seek that info in a table matching TT_%CGGROUPDEFS:
-<code sql>
-select owner, object_name, object_type
-from dba_objects
-where object_name like '%CGGROUPDEFS%' order by 2;
-</code>
-And delete the data:
-<code sql>SELECT 'DELETE FROM ' || OWNER || '.' || OBJECT_NAME || ' ; '
-FROM dba_objects
-where object_name like '%CGGROUPDEFS%' ;
-commit;
-</code>
-(maybe you want to make a backup of the data).
