Full routing table exchange in Link State Routing?

In link state routing protocols, full update that happen every 30 minutes, does the routers exchange the whole routing table with each other? Or exchange something else, not full routing table. If not the whole routing table, what they are exchanged?

The interval depends on the routing table. OSPF will send out a fresh copy of the LSA (link-state advertisement) every 30 minutes. ISIS will send it every 20 minutes. Only LSAs are sent, not the routing table.

Proc fails with sqlcheck=full accessing tables across a link to non 11g db

I am trying to compile programs that were upgraded from 9i to 11g and having issues whenever I try to compile code that accesses non 11g databases across a link when sqlcheck is anything other then syntax.
If I have a select such as
select distinct a.ID_NUM, b.value1, b.value2, ...
from table_a a, table_b@external_db b
where a.ID_NUM = b.ID_NUM and a.process_name='REPORTS';
This compiler sits and hangs for a few minutes then aborts. This problem occurs in Pro*C, Pro*Cobol as well as Oracle Forms.
The query works fine under sql*plus. The compiler just can't handle it.
A work around under Pro*C is to use sqlcheck=syntax when compiling any code that accesses across a link. However this isn't a good workaround since it won't catch errors such as a typo in a column. This also won't work in forms, but a work around is to convert the selects into a view. However that isn't a good workaround due to the number of queries that would need changing.
Has anyone else seen this issue and found out what needs changed in the Database for this to work. I tried searching Oracle's web site but couldn't find any solution.

Rich,
I searched metalink for your issue. This may be a bug in 3.1 which will be fixed in 4.0. Please see Doc ID 740581.1 Database Link Tables Do NoT Show Up In Table Drop Down List In Apex. There is a workaround mentioned in the document.
I'm not sure why I never thought of searching MetaLink, but thanks for the pointer! It doesn't match my circumstances, however. The Bug smells like a view not being queried in the APEX development tool itself -- i.e. the IDE's coding needs changing, not necessarily those apps created with the IDE.
I'm working on getting you access to my hosted app...
Thanks,

Link State Routing Protocol Question

"In LSP, one router in each area is designated as the authoritative source of routing information (called a designated router). Each area router receives updates from the designated router" Why need designated router? How it work? Why can?t it just broadcast LSP and leant the routing information without the need of designated router? Is designate router the same as backbone or root area in OSPF? Is "area" concept only be used in Link State Routing Protocol OSPF?

hi...
you will find area topology in IS IS also...
here we are using the Area as well as DR and BDR for reducing the LSA flooding in the area... each router in ospf area will send update to the DR on multicast address and then DR will send the multicast update to all other router in the area... here each and every router in the area have the full adjucancy with DR but they are not in the full adjucancy with any other router ...
hope this will help you
rate this post if it helps

Routing loop avoidance in Link State

"The link state method is not susceptible to routing loops which is an advantage over the distance vector method" Why? How it avoid routing loop?

Link-state protocols like OSPF use reliable flooding mechanisms to ensure that all routers are acting on the basis of the same information. Loops occur when routers act on the basis of inaccurate or old information. That is what link-state protocols avoid. All routers in a link-state database have the same view of the network.

I don't believe so. For full Internet routes, you'll want a XL variant.

LSAs in link state protocols

Lets say we have a stable network and we are using a link-state routing protocol. Then something fails. Will the routers reflood ALL LSAs when one LSA changes or only refloods the changed LSAs?

Francisco
Only the LSA's that have changed will be advetised out. That is one of the big advantages of OSPF in that only affected links are advertised rather than the entire OSPF database.

How to use a Sybase table in Oracle SQL statement?

How to use a Sybase table in Oracle SQL statement?
Sybase version : 11.9.2.4
Oracle version : 10.2.05
Thanks.

Sybase version : 11.9.2.4
Oracle version : 10.2.05
Thanks.Any Oracle client connected to the Oracle database can access Sybase data through the Database Gateway for Sybase (it requires an additional license) or the Database gateway for ODBC (it's free).
The Oracle client and the Oracle database can reside on different machines. The gateway accepts connections only from the Oracle database.
A connection to the gateway is established through a database link when it is first used in an Oracle session. In this context, a connection refers to the connection between the Oracle database and the gateway. The connection remains established until the Oracle session ends. Another session or user can access the same database link and get a distinct connection to the gateway and Sybase database.
Database links are active for the duration of a gateway session. If you want to close a database link during a session, you can do so with the ALTER SESSION statement.
To access the Sybase server, you must create a database link. A public database link is the most common of database links.
SQL> CREATE PUBLIC DATABASE LINK dblink CONNECT TO
2 "user" IDENTIFIED BY "password" USING 'tns_name_entry';
--dblink is the complete database link name.
--tns_name_entry specifies the Oracle Net connect descriptor specified in the tnsnames.ora file that identifies the gatewayAfter the database link is created you can verify the connection to the Sybase database, as follows:
SQL> SELECT * FROM DUAL@dblink;
Configuring Oracle Database Gateway for Sybase

but it's wrong
please tell me how to left join A1 and A2, thx!

Whats your aim?
Any error message?

TABLE list on linked server?

In SQL Developer, i can see a list of TABLEs in the Connections list, and see TABLE definition and data.
I have a DB Link providing access to a number of TABLEs on a different server. Is there a way to see a similar list of the available TABLE on the linked server?

There is a link at the top of the forum to the SQLDeveloper exchange where you can raise feature requests.
Post a link to your request back here so people can find it more easily to vote on it.
This also looks like the kind of thing which is amenable to an XML extension.

Link-state tracking on 3550

Hi,
I would like to know if the link-state tracking is supported on the 3550. If yes then please let me know on which IOS version. I was not able to check this on the IOS features.
Second question:
Can I trak on sub-interface (VLAN) instead of the full interface?

Hi Amin
I checked out for the same and it says its supported in Cisco 3550 but regarding the exact ios code you better can choose the required version from the feature navigator.

Can I Select from table skipping extents linked with lost datafiles?

Hi~,
I need your help to recover my database.
I'm using oracle 9.2.0.8 at Fedora 3 with no-archive mode.
and I don't have any backup.
Last night, I experenced hard disk failure.
I tried OS-level recovery, but I lost some datafiles of tablespace.
anyway, I wanted to recover my database without data of lost datafiles.
so, I issued "alter database datafile offline drop" and
start oracle instance.
But, datafiles were not removed from dba_data_files view and
extents linked with lost datafiles were not removed from dba_extents view!
Selecting query of some table containing extents linked with lost data files,
I got "ORA-00376: file xxx cannot be read at this time" message.
So, my question is that..
HOW CAN I SELECT FROM THAT TABLE WITHOUT SCANNING EXTENTS LINKED WITH LOST DATA FILES?
Thanks.

Hi,
Without being in archivelog and without backup, one can't do any sort of recovery. That's why backups and archivelog are so so important.
The offline data file command never does actually drop the datafile. It merely indicates to the control file that now the said tablespace will also be dropped. This won't update any view that the files are not supposed to be used or shown to you anymore.
This is what documentation says about the recovery of the database in the NoARch mode,
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14191/osrecov.htm#i1007937
You do need a backup in order to get those tables being read. Oracle doesn't have any feature which can offline/skip the missing extents for you and let you read the data without them.

How to use bind variable value for table name in select statement.

Hi everyone,
I am having tough time to use value of bind variable for table name in select statement. I tried &p37_table_name. ,
:p37_table_name or v('p37_table_name) but none worked.
Following is the sql for interactive report:
select * from v('p37_table_name') where key_loc = :P37_KEY_LOC and
to_char(inspection_dte,'mm/dd/yyyy') = :P37_INSP_DT AND :p37_column_name is not null ;
I am setting value of p37_table_name in previous page which is atm_state_day_insp.
Following is error msg:
"Query cannot be parsed, please check the syntax of your query. (ORA-00933: SQL command not properly ended) "
Any help would be higly appreciated.
Raj

Interestingly enough I always had the same impression that you had to use a function to do this but found out from someone else that all you need to do is change the radio button from Use Query-Specific Column Names and Validate Query to Use Generic Column Names (parse query at runtime only). Apex will substitute your bind variable for you at run-time (something you can't normally do in pl/sql without using dynamic sql)

More than one style for a single link state?

RH 8 outputting CHM
Hello,
Is it possible to define more than one style for a single link state?
For example, I would like a link in the footer of my master page to be smaller than the links that appear in the body of my topics. I want to retain behavior, and simply change the point size.
I can't simply hand format in Design mode, because my link is within a script. Or, am I missing something easy here?
Thanks much.

I'm pleased to say I figured out how to change the formatting of a hyperlink embedded within a script.
Within the script, I used a var string to reproduce the text in my link. Then I used another var to change the string size.
So, here's the part of my script that produces what I'm after:
var mailDisplay = 'Was this information helpful? ';
var str = 'Was this information helpful?';
var mailDisplay = str.fontsize("1");
Upon generation of the CHM, the script trumps the CSS. It's a beautiful thing.

Adding annotations throws off Table of Contents links

I asked this a month ago and got no responses...Help is critically needed. When annotations are added, the bookmarks seem OK on authoring machine, but once PDF is opened on another machine, everything thrown off!
I'm involved in a paperless pilot project and am having a difficult time circumventing an issue in Preview.
I'm re-formatting material for executive meetings from WordPerfect, Word, Excel and PowerPoint into bookmarked PDF format in Adobe Acrobat Pro X. When they are opened in Preview by senior management on MacBook Airs, the Table of Contents links everywhere correctly. However, the moment they add an annotation (in this case, notes), the table of contents is thrown one page off, regardless of their place in the document. Even after removing the note, the table of contents does not revert to the proper place. I'm assuming this occurs because the annotation throws off the markers from the imported bookmarks.
Using Acrobat Reader on the Airs isn't an option since annotations aren't possible. We are also really trying to keep production of the PDFs limited to Acrobat Pro to ensure cross-platform compatibility of the Table of Contents.
Has anyone else encountered these issues? Is there a potential workaround?

A lightweight alternative to Acrobat Pro for creating table of contents for any PDF is PDFOutliner (only $5 on Mac App Store.) The TOC links generated by PDFOutliner don't have the problem you've described above. You could open your PDF in PDFOutliner and re-save it (the TOC will be rebuilt) for a quick test.
Note: I'm the developer of PDFOutliner.
