How to create the Group of cache for many to many relationship tables?
Hi, Chris,.Page 4-4 < < the user manual of the Oracle Database Cache in memory > > there is a saying,
A child table cannot reference multiple parent tables.
If there is a many-to-many relationship table in Oracle and I want to cache in TT, there is not a la carte approach that?
Or I have to logically break his references to the two tables in one of them?
I forgot to mention that I have a root table and one of its child tables is a many-to-many relationship table.
Yes, that's correct. You can not exactly this model in TimesTen. You to omit some of the relationships so that things are defined in TimesTen as a pure parent/child relationship. You can also consider putting the tables into groups separate cache. Of course, there are consequences to this:
1. the 'missing' relationship cannot be run by TimesTen. The application must respect/run it. If this is not some updates may not to be propagated to Oracle if they violate the relationship in Oracle.
2 If the parallel AWT is configured (to improve the performance of spread) it will not be used for all tables where they lack of relationships. All updates to the tables in the order will apply.

Created the Group Linked Clone/pool - now how to connect to / them?
OK, I got the pool group / a linked clone. Now, what should I do to connect with them? I worked off the coast of the "VMware-View4-EvaluatorsGuide" and there is nothing after having created the group/pool? So, how do I connect to this pool? I've created or set it to 5 desktop computers.
Anything will help maaaaannnn... cuz this trial and the guide is just don't do it for me.
Thank you
OK, don't know if the guide had suggestions on the construction of your model, but you must make sure that the view agent is installed on your VDI machines. You must also ensure that the client view is installed on the computer that you connect from. Once entitle those who have been verified a user to use the admin view pool manager. You can then connect on the vdi client and should be able to access the pool. Simply specify your connection broker name after you run the client from the view.

How to create the column of the table for long-form Master detail relationship
Apex 4.1
Oracle 11g
I created a form master detail and see the main table hotel_list and table hotel_mapping as detailed below.
Hotel_list
ID HOTEL_NAME
1 Holiday Inn
Hotel Hilton 2
Hotel_mapping
ID HOTEL_NAME MAPPING_NAME
1 Inn Holiday Inn Select hotel
2 holiday hotel Holiday Inn Select
3 hotel Holiday Inn Holiday Inn Hotel
4 Hilton Hotel Hilton Hotel chain
Hotel Hilton 5 HiltonHotel
Table Hotel_name Hotel_list is a linked table Hotel_mapping
When I add a line to the Hotel_mapping table for the selected row in the hotel_list table, mapping_name of column is null, therefore impossible to create the relationship between the main table and the secondary table.
I would like to know, how to create the relationship?
Thank you very much
Best regards
Yong Huang,
simple step see creating a form detailed master with APEX - Assistant Master retail
and check how to maintain the relationship between two tables,
simple return the packaged application «Sample of Masters details»
and try to understand this concept...
In your example, use Hotel_list.ID as a foreign key in the table Hotel_mapping
and maintain the relationship with the column ID...
and choose the display type of the column Hotel_list.ID in table Hotel_mapping as List(Query Based LOV) select.
otherwise the best way is to create sample on oracle.apex.com
I hope this helps...
Leave.

Create a group of cache problem
Hello
I have three tables T1, T2 and T3 in Oracle. The T3 table has two foreign keys F1 and F2 which refers to tables T1 and T2, respectively. When I try to create the cache group in TimesTen for table T3, I get the following error:
«8211: user table.» T1 is not a member of the Group of cache.
Here's the script for Oracle and TimesTen
Oracle
======
CREATE TABLE T1
(ID1 integer PRIMARY KEY,
A varchar (30));
CREATE TABLE T2
(ID2 integer PRIMARY KEY,
A varchar (30));
CREATE TABLE T3
(ID3 integer PRIMARY KEY,
OF THE varchar (30),
Whole F1 references T1 (ID1),
Entire F2 references T2 (ID2)
);
TimesTen
========
CREATE GROUP OF READONLY C_T1 CACHE
AUTOREFRESH INTERVAL 5 SECONDS
FROM T1
(ID1 NUMBER (38) NOT NULL PRIMARY KEY,)
THE VARCHAR2 (30));
CREATE GROUP OF READONLY C_T2 CACHE
AUTOREFRESH INTERVAL 5 SECONDS
THE T2
(ID2 NUMBER (38) NOT NULL PRIMARY KEY,)
THE VARCHAR2 (30));
CREATE GROUP OF READONLY C_T3 CACHE
AUTOREFRESH INTERVAL 5 SECONDS
T3)
ID3 NUMBER (38) NOT NULL PRIMARY KEY,
F1 NUMBER (38) NOT NULL,
F2 NUMBER NOT NULL, (38)
FOREIGN KEY (F1) REFERENCES (ID1) T1,
FOREIGN KEY (F2) REFERENCES T2 (ID2),
THE VARCHAR2 (30));
How can I create groups of cache of these paintings? Please notify
Thank you
Vishin DasThere are two problems here:
1. If you want to set a FK between tables cached in TimesTen then all tables must be part of the same group of cache.
2. part of a group of cache, that you must have a single table at a higher level and all the other tables should be child tables of this table or one of its children. Which tables should be linked hierarchically.
So at first glance you may not be cached in this series of paintings in TimesTen, but actually you can because...
1. you do not have to set all the present FKs in oracle in cache TT groups. for groups of READONLY cache isn't generally a problem because FK execution happens in Oracle. Sometimes, it is not a problem for WAT cache groups either, but you know how the application handles data to be sure about this.
2. all READONLY cache with the same AUTOREFRESH interval groups are updated in the same transaction; You can avoid transactional inconsistencies in the data in the cache.
So the best solution here is probably:
CREATE GROUP OF READONLY C_T1 CACHE
AUTOREFRESH INTERVAL 5 SECONDS
FROM T1
(ID1 NUMBER (38) NOT NULL PRIMARY KEY,)
THE VARCHAR2 (30));CREATE GROUP OF READONLY C_T2 CACHE
AUTOREFRESH INTERVAL 5 SECONDS
THE T2
(ID2 NUMBER (38) NOT NULL PRIMARY KEY,)
THE VARCHAR2 (30));CREATE GROUP OF READONLY C_T3 CACHE
AUTOREFRESH INTERVAL 5 SECONDS
T3)
ID3 NUMBER (38) NOT NULL PRIMARY KEY,
F1 NUMBER (38) NOT NULL,
F2 NUMBER NOT NULL, (38)
THE VARCHAR2 (30));CREATE INDEX T3_IX1 ON T3 (F1);
CREATE INDEX T3_IX2 ON T3 (F2);Indexes are created based on the assumption that, when the application queries these tables cached, it is likely to join based on the PK/FK relationship. The presence of the indices will speed up joins immensely.

Satellite P750 PSAY1A: how to create the recovery Toshiba on the new HARD drive partition
Hello
I have an old Toshiba Satellite P750 (PSAY1A-01Y022). I just upgraded my memory from 4 GB to 8 GB and am preparing to take my 500 GB HARD drive 1 TB. I had to order the disk online and wait to happen.
I always try to understand how to create the arrival of my new HARD drive Toshiba Recovery Partition. I do the same thing for an old book, I handled based on something similar to it's original factory State.
I have reflected on the recovery partition, but does not know how it was created. It is not NTFS. Does anyone have experience in the creation of a Toshiba Recovery on a new HARD drive Partition?
And the help is very appreciated.
Thanks and regards,
DineshRecovery partition can be created when you use the original Toshiba Recovery disk and install recovery image. Before the partitions to boot OS install will be automatically created, recovery image copied on a recovery and then partition as last step recovery image installation starts.
A sort of migration of files from one to the other HARD disk is not solution.
Only for laptop with factory will work and the usable recovery partition.
