7 1 Access Contr ol Introduction Access Control W ith T imesT en you can optionally install a layer of intern al security , which throughout the TimesT en docum entat ion set and in the installation scripts is referred to as “Access Control.
8 Oracle T imesT en In-Memo ry Datab ase Installation Guide Cache Connect For Cache Connect, the T imesT en inte rnal user must match the Oracle user . External Client/ Server users mu st match the Oracle user . If you are using the Cache Connect Administrato r interface, the user must be an internal T imesT en user .
Access Contr ol 9 % ttDaemonAdmin -start T o stop an instance: % ttDaemonAdmin -stop Inst ance data store A DSN for a minimal instance-wide data sto re is defin e d by TimesT en at install time to guarantee that TimesT en alw a ys has som ething with which to connect.
10 Oracle T imesT en In-Memory Database Installation Guide Note: All examples in the TimesT en d ocum entation set use the name timesten to represent the in stance administrator . For details on estab lishing the T ime sT en instance admini strators group, see “Create the TimesTen instance ad ministrators group” on page 37 .
Access Contr o l 11 automatically converts the external us er name to upper case, rendering it case insensitive. The PW DCrypt attribute allows you to encr ypt a password rather to use cleartext passw.

87 – 3 Data S tor e Upgrades Introduction When a T imesT en data store is loaded into shared memory , many of its attributes are fixed, including size, logging options, TimesT en software release number , and the location of its checkpoint and log files on disk.

Data S tore Up gr ades 89 the same as the character set speci fied for the Oracle database that the T imesT en data store connects to. • Replication is not possible between data stores with different character sets. Because data stores created with versions of T imesT en prior to 7.
90 Oracle T imesT en In-Memory Database Installation Guide Converting dat a types to Oracle dat a types Note: If you intend to use your data store with T imesT en Cache Connect to Oracle, you must convert your data types to Oracle data types. However , you will not b e able to perform an online upgrade usin g replication.
Data S tore Up gr ades 91 Dat a store character set conversion Beginning with T imesT en 7.0, a char acter set must be specified for each T imesT en data store usi ng the DSN attribute DatabaseCharacterSet . In some cases, you may need to change the configured data store character set as part of the upgrad e proc ess.
92 Oracle T imesT en In-Memory Database Installation Guide 4. Load the data store from the file using ttMigrate with the -noCharsetCon version command line option. This option ensures that no character values are changed when the data is loaded into the DSN using the new character set.
Data S tore Up gr ades 93 Upgrade modes T imesT en allows you to perform th ese kinds of upgrades: In-place upgrades In-place upgrades are av ailable for moving to a new patch release of T imesT en, such as moving from the first patch release of 7.0, v ersion 7.
94 Oracle T imesT en In-Memory Database Installation Guide Online upgrades with replication When upgrading to a new major rel ease of TimesT en, y ou may have a mission critical data store that needs to remain continuously availab le to your applications.

Starting with 7.0, T imesT en Server is able to talk directly to all versions of TimesT en Client fro m 6.
96 Oracle T imesT en In-Memory Database Installation Guide utility . (See "tt Admin" in Oracle T imesT en In-Memory Databa se API Refer e nce Guide .) In order to unload a data store: 1. Disconnect all applications from the data store. 2. In this example, the data store original is from the previous release.
Data S tore Up gr ades 97 Performing an offline upgrade Y ou can do an offline upgrade by exporting the data store into an external file using either the ttMigrate or ttBackup utility , then restoring the data store with the desired changes.
98 Oracle T imesT en In-Memory Database Installation Guide Note: After ttMig rate has been used, all autorefresh cache groups in the destination data store have AUTOREFRESH ST A TE set to OFF , no matter how it was s et on the source d ata store. Reset AUT OREFRESH ST A TE to ON by using the ALTER CACHE GROUP statement.
Data S tore Up gr ades 99 Note: Before mo ving a repli cated data store to another machine, you should be experienced with TimesT en replication. W e highly advise calling T imesT en customer support for help with this procedure. T o copy a data store from one system to another with the same CPU architecture and operating system: 1.
100 Oracle T imesT en In-Memory Data base Installation Guid e Reducing dat a store size Once a data store has been define d with a particular size for the permanent partition (indicat ed by the PermSize DSN attribu te), it cannot be loaded at a smaller size, even if tables or rows are deleted.
Data S tore Upgrades 101 Note: The temporary partiti on size of a data store may be changed by simply modifying the Te m p S i z e attribu te of th e DSN, unloadin g the data store from memory , and then reconnecting to it. See “Unloading a data store” on page 95 for the steps to unload a data store from memory .

Data S tore Upgrades 103 Now upgrade data store subscriber1 from release 5.1 to release 7.0. Perform the f ollowing steps: 1. On the machine subscriberhost , use the 5.1 release’ s ttAdmin ut ili ty to stop the replication daemon: ttAdmin -repS top subscribe r1 2.
104 Oracle T imesT en In-Memory Data base Installation Guid e Performing an online upgr ade with replication In “Performing an offlin e upgrade” on page 97 we showed how to perform various maintenance operations on TimesT en data stores that require that all applications be stopped.
Data S tore Upgrades 105 release data store using ttMigrate from the newer release, and then reconnecting all applications to the upgraded data store. Note: The ttMigrate -r -rename option, used to rename the o wner of data store tables, cannot be used with online upgrades.
106 Oracle T imesT en In-Memory Data base Installation Guid e 2. Connect all applications to the active data store, if they are not already connected. 3. Disconnect all applicatio ns from the upgrade data store. 4. Set replication to the upgrade system to the pause state.
Data S tore Upgrades 107 After the above procedures have been carried out on the upgrade system, the active system can be upgraded using the same steps. Limit ations Online upgrades can be performed only on data stores for which all the user tables meet the replication requi rements.
108 Oracle T imesT en In-Memory Data base Installation Guid e Online upgrade example This section describes how to do an online upgrade of two bi- directionally replicated TimesT en data st ores, using a concrete example.
