Does OracleConnectionCacheImpl cache physical or logical db connections?

Hello -
Can anyone tell me if the "cache" in oracle.jdbc.pool.OracleConnectionCacheImpl is of logical or physical database connections?
(My app selectively enables roles (depending on end user) on the connections it gets - trying to determine if I can use OracleConnectionCacheImpl as a data source...)
-- Thanks

Does JNDI cache physical IP address on ldap lookups? And How to stop it?

We are using Oracle's 11.1.0.6 thin jdbc driver using the 'ldap lookup' syntax for database connect string lookups. The ldap server we specify is a DNS alias pointing to a hardware server load balancer, which returns different IP addresses based on load and current availability. During maintenance, we will remove a server from the load balancing rotation, but applications will continue to try connecting to this physical IP address even though DNS is no longer serving it up as a valid address. This causes continuous application failures until either the server is brought back up or the application is bounced. Only the application needs to be bounced, not the websphere or the physical server, so the caching is not being done at the server level.
We've used the tracing capabilities in the 11g jdbc driver to trace the fact that Oracle is passing in thd DNS alias name and not an IP address to the JNDI interface, so it appears the caching is occurring at the JNDI level. Unfortunately, tracing is not detailed enough to show exactly what JNDI calls are being made.
Is there any JNDI attributes that can be set to stop JNDI from caching this IP address and force it to re-evalute the new DNS lookup at each invocation?
We already know Oracle's jdbc thin driver supports specifying secondary failover ldap lookup strings, but this IP address is also getting cached, so while this will reduce the frequency of errors, it won't eliminate the problem, especially if a server is removed from the load balancing rotation permanently.

Creating logical/virtual connection object from physical connection

Can anybody help me what is creating logical/virtual connection object and how to create it from physical connection in java ??
Thanks in advance...

WHile you are waiting for an answer, you might want to review the related Oracle documentation:
For 10g, all docco is at http://www.oracle.com/pls/db102/portal.portal_db?selected=3 and docco I suspect will help you is "Java Developer's Guide" and "JDBC Developer's Guide and Reference"

OBIEE -10.1.3.4.1 - high physical and logical query response

Hi All,
I am facing an performance issue in OBIEE 10g .My report is taking 2 mins to come up and when i fired the physical query in the db the data is coming in 2 secs.
Below is the details from the log file.Here I observed that response time for physical and logical query is 109 sec ~ 2 mins.Please provide me the helpful pointers.

Did you run the SQL from a client on the OBIEE server or your local machine? Does the Physical SQL on the OBIEE server against the DB run in 2 Seconds and when sent by the OBIEE server it takes 109 seconds?? Is that correct?

Logical table does not join to any logical table

HI,
I want to implement Business Unit hierarchy for drill down in OBIEE so I’ve created a custom table with the hierarchy information,
I’ve imported that table in the out-of the box physical schema & defined a relationship between the W_ORG_D table & my custom INVENTRY_ORG table as INVENTRY_ORG.BU_ID = W_ORG_D. VIS_PR_BU_ID* but when I try to check in my changes I’m getting the following error.*
Logical table INVENTRY_ORG does not join to any logical table.
Kindly let me know how to resolve this error.One more doubt i have is can we import custom tables in the out of the box OBIEE mappings for SIEBEL..that is the core subject area.
Thanks,

Hi user10340125 ,
1) I think you have joined tables in physical layer, but you have not created complex join in logical layer.
Check your consistency and see what warnings you are getting.
2) Yes you can import custom tables in whatever subject area. Once you imported tables in physical layer, then they all are just objects, so you can freely play around with them. Just for best practices, make sure you follow proper naming convention for custom tables and columns..

Logic Remote connectivity issues after updating to iOS 8 (solved!)

Has anyone else has been experiencing connectivity issues with Logic Remote after updating to iOS 8?
After updating to iOS 8 I could no longer connect so I sent a feedback report to Apple and got a response that cleared up my problem immediately:
Navigate to the following directory on your desktop system running GarageBand:
~/Library/Containers/com.apple.garageband10/Data/Library/Preferences/
You can quickly navigate there using the “Go” menu in Finder -> Go To Folder (shift-command-G), then copy this path:
~/Library/Containers/com.apple.garageband10/Data/Library/Preferences/
In the Preferences folder should be a file named "com.apple.garageband10.cs”.
Make sure GarageBand is not running and delete the "com.apple.garageband10.cs” file.
Relaunch GarageBand and see if you should now be able to connect.
The same can be done for Logic by navigating to:
~/Library/Preferences/
And deleting "com.apple.logic.pro.cs" and restarting Logic.
Note that doing this will fix Logic Remote connectivity issues (and possibly other problems with latency and mixer functionality) but will also delete any other Controller settings that you've configured with Logic, if you happen to be using another controller of some sort.

Thanks very much! This solved my connection problem.

Query on Physical Architecture,Logical Architecture and Model

Hi Experts,
I have a confusion regarding Physical Architecture,Logical Architecture and Model.Please tell me what type of information or data these above three hold.
Thanks

Physical architecture contains information on the physical setup of your environment i.e. server names, jdbc connection strings, usernames, Passwords etc.
The logical architecture provides a layer of abstraction that allows you to group via contexts similar Physical architecture components which reside in different locations/environments.
Models are the reversed representations of the objects in your physical architecture i.e. tables, flat files etc. Models are used as sources and targets in your interface design

Physical Vs Logical Partitioning

We have 2 million records in the sales infocube for 3 years. We are currently discussing the pros and cons of using Logical partitioning Vs Physical Partitioning. Please give your inputs.

hi
there are two types of partitioning generally talked about with SAP BW, logical and physical partitioning.
Logical partitioning - instead of having all your data in a single cube, you might break into separate cubes, with each cube holding aspecific year's data, e.g. you could have 5 sales cubes, one for each year 2001 thru 2005.
You would then create a Multi-Provider that allowed you to query all of them together.
A query that needs data from all 5 years would then automatically (you can control this) be split into 5 separate queries, one against each cube, running at the same time. The system automatically merges the results from the 5 queries into a single result set.
So it's easy to see when this could be a benefit. If your queries however are primarily run just for a single year, then you don't receive the benefit of the parallel processing. In non-Oracle DBs, splitting the data like this may still be a benefit by reducing the amount of rows in the fact table that must be read, but does not provide as much value to an Oracle DB since Infocube queries are using a Star_Transformation.
Physical Partitioning - I believe only Oracle and Informix currently support Range partitioning. This is a separately licensed option in Oracle.
Physical partitioning allows you to split an Infocube into smaller pieces. The pieces, or partitions, can only be created by 0FISCPER or 0CALMONTH for an InfoCube (ODSs can be partitioned, but require a DBAs involvement). The DB can then take advantage of this partitioning by "pruning" partitions during a query, e.g. a query only needs data form June 2005
The DB is smart enough to restrict the indices and data it will read to the June 2005 partition. This assumes your query restricts/filters on the partitioning characteristic. It can apply this pruning to a range of partitions as well, e.g. 0FISCPER 001/2005 thru 003/2005 would only look at the 3 partitions.
It is NOTsmart enough, however, to figure out that if your restrict to 0FISCYEAR = 2005, that it should only read 000/2005 thru 016/2005 since 0FISCYEAR is NOT the partitioning characteristic.
An InfoCube MUST be empty in order to physically partition it. At this time, there is no way to add additional partitions thru AWB, so you want to make sure that you create partitions out into the future for at least a of couple of years.
If the base cube is partitioned, any aggregates that contain the partitioning characteristic (0CALMONTH or 0FISCPER) will automatically be partitioned.
In summary, you need to figure out if you want to use physical or logical partitioning on the cube(s), or both, as they are not mutually exclusive.
So you would need to know how the data will be queried, and the volume of data. It would make little sense to partition cubes that will not be very large.
physical partitioning is done at database level and logical partitioning done at data target level.
Cube partitioning with time characteristics 0calmonth Fiscper is physical partitioning.
Logical partitioning is u partition ur cube by year or month that is u divide the cube into different cubes and create a multiprovider on top of it.
logical Vs physical partitions ?

Export physical and logical details on ASA 5520 and 8.0 software

Hello...does anybody know if there is any way to export details of the physical and logical interface details (including interface descriptions) to Excel, PDF or and other format from the command line or ASDM?
Thanks,
John

Export directly in xls, xlsx or pdf - no.
The output of "show run interface" or "show interface" is pretty structured however and easily parsed by Excel - either manually or via a macro. See output below (you can omit the interface identifier to get all interfaces. I used one for brevity.)
One can build a script to log in, perform an arbitrary command logging the output to a file which can then be massaged to extract the information you want in a suitable format (csv, etc.). Once in Excel it can be saved as pdf if you're so inclined.
Of couse, some of the full-featured network management tools do a lot of this (and lots more) if you have them.

Changing ip of physical and logical host

I have a 2 nodes Sun cluster 2.2 working. I have to put it in another lan, so I have to change both Physical and logical host and terminal concentrator and console ip addresses. How can I do?
Thanks

I don't see a reply so I'll take a shot. Just like you have 0-9 for numbers and you can arrange them anyway you want, you still only have 0-9. You have the physical (system block and datafiles) which are somewhat static. Then you have the the logical (tablespace, segements, extents)which are volatile and connected by chaining (links) which may be all over the place in the physical but appears to be one whole unit in the logical. Just like an image on a TV screen wearing a red hat, you see a red hat (logical) but it is actual pixels which are chained or linked (data pointers) to each other by the color red. I hope that helps until someone comes by with a better answer.

Whar are logical table, Physical table Logical data Source

Hi,
Can any one explain me in details what Whar are logical table, Physical table Logical data Source.
Any qucik help will be graetly appreciated

In OBI there are three layers - Physical, Business Model and Mapping (BMM) and Presentation.
As the name specifies the Physical layer mainly contain physical aspect of the application like which connection to use, which schema (also catalog in case of SQL server) to connect and also which table to use. This layer confirms the PK_FK joins for the related tables. This layer mainly depicts how the data has been stored in the database layer.
On top of this layer you will have you BMM layer. The place where all work of a developer starts. You will structure the tables accourding to the business need. The structure has to be a STAR schema. All the entities in this layer are called logical because they do not directly represent any database object rather they provides a logical mapping to the database entities. This becomes clear when you use more that one Logical Table Source (LTS) for your logical tables. One logical column can map to N number of physical columns based on context. You can also create calculative columns in this layer which are totaly logical in nature.
I am not writing anything on Presentation layer as it is not in you question. :)
Hope this will help.

Physical standby, logical standby which one shud i prefer?

Hi ,
how to decide which standby to create that is whether Physical or Logical.
I want to create it for database failover. so which one i shoul prefer?
pls give ur suggestions.
Thanks,
Kuamr.

Physical standby is the easiest to setup and administer and supports all datatypes. You can use it for reporting (if it's rarely req'd), except for you would have to cancel the recovery, open the db is a read-only mode, and then put it back in the recovery mode.
Logical standby is a pain, but you can run reports at anytime without canceling recovery. logical does not support certain datatypes, like IOT's, BLOBs, etc.

Physical versus Logical Lookups

Which type of lookup table is better to use - physical or logical ? does logical lookup table joins are done in memory or pushed to database.
Thanks

user457687 wrote:
logical lookup table joins are done in memory or pushed to database.Lookup's done in the physical layer are pushed to the database where as in the BMM layer, the BI Server does the in-memory joins and aggregations as needed. I believe physical lookup's are better compared to the logical lookup's as the joins are pushed to the database and they should perform faster than the in-memory joins.

Finding of the Logical and Physical filename,Logical and Physical Path

Hello All
Where and how can I find the below details in an SAP server
Logical filename:
Physical filename:
Logical path:
Physical path:
Regards
Kalyani

hi
Physical file is what you see from the OS level.
Logical file is what ABAP code can call certain functions to read/write.
Transaction FILE would link them together. Typically the logical path ends with "<FILENAME>", and the logical file refers to the logical path.
To extract the physical path from the logical path name
DATA: lf_mandt TYPE sy-mandt,
lf_opsys TYPE sy-opsys.
lf_mandt = sy-mandt.
lf_opsys = sy-opsys.
To extract the physical path from the logical path name
CALL FUNCTION 'FILE_GET_NAME'
EXPORTING
client = lf_mandt
logical_filename = p_unix
operating_system = lf_opsys
IMPORTING
file_name = gwa_input
EXCEPTIONS
file_not_found = 1
OTHERS = 2.
IF sy-subrc EQ 0.
Concatenating the physical path and the input unix file name
CONCATENATE gwa_input p_file INTO gf_file .
ENDIF.
You need to tak ehelp of ABAPer for this

My Canon MX 922 does not scan. My printer is connected via cable. Wireless doesn't work either.

My Canon MX 922 does not scan. My printer is connected via cable. Wireless doesn't work either. I get an error message with multiple suggestions but none of them apply to my situation.
I am so dissatisfied with this printer. I'm sorry I got it from Amazon because now it is a hassle to return it. I will never buy another Canon.
The printer menus are confusing. I hate using it. I loved my previous Canon which finally stopped working after many years, that's why I purchased a newer Canon model. Never again. Stick with cameras.
Marcy Hotz

This note won't be as angry and frustrated as the last one...
Because I still had my old printer drivers and other applications on my hard drive, I think the application was trying to connect with the old printer. I deleted all the old stuff.
I also had several scanning applications on my drive which just confused me.
When I used the actual Canon MX922 application, I was able to scan but could only save as JPG, TIF or BMP (and one more, I forget which). So I did some research on the Canon site and found out how to save documents as PDF files using the Canon IJ Scan Utility.
It works now. So I'm satisfied, will keep this maching. I just had to take some time, sit down and focus on the problem.
