how to change OracleNetServiceName = "orcl_db" to OracleNetServiceName = "MYdatabase"
Thanks!

Answer 1

You should create the cache groups by using cachadmin user, not use object owner user.
In Oracle DB:
SQL> @grantCacheAdminPrivileges "cacheadmin"
Please enter the administrator user id
The value chosen for administrator user id is cacheadmin
***************** Initialization for cache admin begins ******************
0. Granting the CREATE SESSION privilege to CACHEADMIN
1. Granting the TT_CACHE_ADMIN_ROLE to CACHEADMIN
2. Granting the DBMS_LOCK package privilege to CACHEADMIN
3. Granting the RESOURCE  privilege to CACHEADMIN
4. Granting the CREATE PROCEDURE  privilege to CACHEADMIN
5. Granting the CREATE ANY TRIGGER  privilege to CACHEADMIN
6. Granting the DBMS_LOB package privilege to CACHEADMIN
7. Granting the SELECT on SYS.ALL_OBJECTS privilege to CACHEADMIN
8. Granting the SELECT on SYS.ALL_SYNONYMS privilege to CACHEADMIN
9. Checking if the cache administrator user has permissions on the default
tablespace
     Permission exists
11. Granting the CREATE ANY TYPE privilege to CACHEADMIN
********* Initialization for cache admin user done successfully *********
SQL>In TimesTen:
Command> CREATE USER cacheadmin IDENTIFIED BY oracle;
User created.
Command> GRANT CREATE SESSION, CACHE_MANAGER, CREATE ANY TABLE, DROP ANY TABLE TO cacheadmin;
Command>
Command> CREATE USER oratt IDENTIFIED BY oracle;
User created.
Command> grant create session to oratt;
Command>

Command> call ttCacheUidPwdSet('cacheadmin','oracle');

Command> Additionally dont forget to issue the grants for cacheadmin user in Oracle DB
SQL> GRANT SELECT ON readtab TO cacheadmin;
Grant succeeded.Regards,
