TimesTen In-Memory :: Manual Refresh Cache Groups From Oracle DB?
May 3, 2013we want to truncate a oracle Table in the Oracle DB. After the truncate the fact table will be loaded again. After the new load in the fact table we want to tell the times ten db to refresh the cache table. The cache Table is a user owned read-only cache group with no autorefresh. We want to tell times ten in a PL/SQL Block from Oracle DB that starts the refresh from the cache group in times ten. The refresh should not be a autorefresh because the refresh should only start if the fact table will new loaded after the truncate.

Inserting Timesten Cache Is Taking More Time Than Insert In Db11gR2?
Jan 20, 2011We are inserting data using JDBC (Java program) in Oracle 11gR2 DB and Timesten to oracle (using AWT cache group) . In reality insertion in oracle is faster than Timesten Cache DB.
Timesten version - TimesTen Release 11.2.1.7.0 (64 bit Linux/x86_64)
1. It is Client/Server Model.
2. Cpu has 4 core and we are using 3 core for insert the Data.
3. Perm and Temp size is big enough compare to Data Size
4. auto commit=0
5. durable commit=0
6. PassThrough=1
7. LogBufParallelism=3
8. LogPurge=1
9. LockWait = 0.1

Sep 2, 2013We cache oracle 11g2 data in timesten 11.2.2.5.0 ( IMDB ) We can't find any trigonometric functions like cos(x), sin(x) or so in timesten. Does that means timesten doesn't support trigonometric functions?

TimesTen In-Memory :: Unable To Receive XLA Events After A While?
Mar 12, 2013We have been using XLA to capture events on TimesTen for a while now without any issues. We were on TimesTen 7.0.5 and then moved to 11.2.2.3.0 and now 11.2.2.4.0. The XLA processes used Java 6 64 bit and works well with TimesTen versions 11.2.2.4.0 - 64 bit and 11.2.2.3.0 - 64 bit, without any issues.
However, we recently upgraded to Java 7 64 bit both during build time of our XLA processes as well during runtime. The problem we see now is that XLA process upon startup processes events for a while and then after that doesnt receive any events. The process doesn't throw any errors/exceptions. If we restart the XLA process, all the unprocessed events are received and then it behaves normally for a while after which it fails to receive any further events.
Is there any issue with Java 7 64 bit and the TimesTen XLA API? I read the TimesTen 11.2.2.4.0 manual and it says that Java 7 and the ttjdbc7.jar have been certified to work well. Was just wondering if there were any other issues.
In addition, to debug the problem, we ran XLA on a single node and on a two safe setup. The same observations are noted. On Java 6, the process runs just fine capturing all events without any issues, but with Java 7, the issues persist.
In addition, we are only performing updates/inserts on to TimesTen, no delete actions. The OS on which TimesTen's and XLA runs is Red Hat Enterprise Linux Server release 5.7 (Tikanga).

TimesTen In-Memory :: OracleDataReader - Object Reference Not Set To Instance Of Object
Jan 25, 2013I have a problem with executing oracleCommand.ExecuteReader() method. Whatever I try it always returns null and it won't create OracleData reader object. I'm using ODAC 1120320_x64 for .net 4.0 and timesten112241.win64. Don't sure what to do. Debugger is showing strange thing in OracleConnection object : ConnectionState = Closed, but output of ttStatus shows connection to TimesTen data store and ExecuteNonQuery() command works just fine with or without (in or out) parameters. But when I try to execute some query with multile output such as select *, I can't get any result.
I also have a strange problem with connection.Open() When I execute Open() i throws AccessViolationException that can be handled with [Handle ProcessCorruptedStateExceptions] attribute, but connection is established after that and my application works fine until I try to instance OracleDataReader object.
Here is the code:
OracleCommand select = null;
OracleDataReader reader = null;
select = new OracleCommand(selectStmt, connection);
select.CommandType = CommandType.Text;
try
{
reader = select.ExecuteReader(); // this line throws NullReferenceException
if (reader.HasRows)
{
[code]....
Just to mention, I tried it with different queries (pl/sql, plane sql, stored procedure) and all of them works fine in SQL Developer, but not in app.
Application Express :: How To Create Radio Groups Dynamically Based On Records In A Table
Nov 29, 2012below requirement..
We have certain records like SQL, PL/SQL, Reports, Forms, OAF etc in a table. We wanted to capture rating for each of these criteria. So we want a form to be displayed dynamically..
SQL 1 2 3 4 (1,2,3,4 represent radio buttons)
PL/SQL 1 2 3 4
Reports 1 2 3 4
Forms 1 2 3 4
OAF 1 2 3 4
If we add another row, XMLP in that table additional radio button should be displayed automatically..

View 1 Replies View RelatedServer Administration :: Settings Infringe On Any Available Memory On System That Is Already Tight On Memory?
Jul 25, 2012I have the following setup
SQL> show parameter sga;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 3G
sga_target big integer 2G
from what I read I beleive this will initially grab 2GB of memory on startup and will grab up to to 3GB of memory total for the SGA. The "total" memory can be allocated to different peices of the SGA when needed but will never exceed 3GB. Is this correct or would these settings infringe on any available memory on a system that is already tight on memory?
Secondly, what happens if both these values are set to the same value?
ASM Disk-groups / RAID?
Feb 25, 2011We have a new implementation which will be using ASM with RAID. The data area needs to be 3TB, and the recovery area, to be used for archive logs and RMAN backups, needs to be 1TB.
The configuration i'm thinking about now is:
+DATA diskgroup: 5*600G disks, using RAID 1+0 (this will include control files)
+FRA diskgroup: 2*500G disks, using RAID 1
+LOG diskgroup: 2*1G disks, using RAID 1 (this is only for redo logs)
So here are my questions:
1. Am I right in supposing that we would get the best performance on the +FRA and +LOG diskgroups by not using RAID 1+0?
2. It has already been agreed to use RAID 1+0 for the +DATA diskgroup, but I can't see the added benefit of this. ASM will already stripe the data, so surely RAID 0 will just stripe it again (i.e double striping the data). Would it not be the better just to mirror the data at a hardware level?

View 1 Replies View RelatedOne Materialized Views In Two Refresh Groups
Sep 11, 2013I have 5 MViews that I want to refresh in two occasions, every Sundays and at the 1st of the month. I created a Refresh Group for the weekly and that work fine.

You can only have a materialized view in one refresh group? What options to I have to refresh it in different intervals?
Materialized Views Vs Refresh Groups?
Sep 29, 2010We recently migrated a database from 9i to 10g (overdue we know!!) and discovered that dbms_mview.refresh default behavior was turned upside down - meaning that 10g didn't first truncate the MV to refresh it. We're trying to unwind a lot of legacy issues, but it also turns out that we also have 100 REFRESH GROUPs and 100 MATERIALIZED VIEWs. That means a 1 to 1 relationship between RGs vs MVs. There is one MV defined to each RG.
These are my questions:
1) Does a 1 to 1 relationship between RGs and MVs make sense to anybody? The original implementors are gone and we can't fathom the reason for this.
2) Is there any reason why I shouldn't convert these 100 groups to plain and simple 100 MVs? I don't want the delete/insert refresh behavior of dbms_refresh.refresh and I do want the truncate behavior of dbms_mview.refresh ATOMIC=FALSE for refreshing a standard MVIEW
SQL & PL/SQL :: Retrieving Related Records As Groups
Mar 12, 2008I have a table of N records with: Name SeqNo ID Col4 ... ColX
where Name and ID are non-unique, and SeqNo is a monotonic non-consecutive sequence 0 .. N that is unique within ID..I'd like to generate the following 'groups': For each record where SeqNo = 0, sorted by Name, create the 'group where ID is the same, ordered by SeqNo irrespective of the
values of any of the other columns. For instance, if the table contained:
NameSeqNoIDCol4 ... ColX
RPL2975...
TLM0444...
AAB2801...
AZZ0801...
ABA3444...
KTT4975...
ABA1801...
YHG0975...
DEF1444...
I'd like to generate:
NameSeqNoIDCol4 ... ColX
AZZ0801...
ABA1801...
AAB2801...
TLM0444...
DEF1444...
ABA3444...
YHG0975...
RPL2975...
KTT4975...
I got my desired results by brute-forcing via four sub-queries:
Sub-query 1 - Generate the sorted Names with SeqNo = 0
Sub-query 2 - Expand above with the additional columns,
maintaining original order
Sub-query 3 - For each of the records from sub-query 2,
generate the 'dependents' having the same ID
and SeqNo != 0
Sub-query 4 - Expand above with the additional columns,
maintaining original order of sub-query 1
Main query - Create UNION of 2 and 4, sorting by original
order and SeqNo
if there were not a simpler approach - after all, this must be a fairly common issue when generating BOMs.
