  Hi all

  We plan to patch Linux Redhat Enterprise Server (6.4 and 6.5) to 6.7.

  I tried Searchin' on support of oracle for the compatibility of the database for Linux patches, but not able to find accurate information.

  can anyone share the ID document or information related to it.

  Oracle used shared memory to implement the CMS, which was the largest consumer of memory of the Oracle instance. The problem is that in of many modern operating system, including linux, it is difficult to define the use of memory real fo software. This is because the memory used by a process consists of shared (for example, shared memory, shared library, executable code) and private components (for example, the heap, stack). Utilities such as top, ps, etc. provides all the visible memory through a process, regardless of whether or not it is shared. Accordingly, the total amount of VIRT etc. will be inflated by shared components. A more accurate figure of the use of memory, shared memory / library / code should be counted once.

  Before 11g, Oracle used System V ipc, and it is possible to control the amount of memory allocated by using IPCS. 11 g, Oracle passed to/dev/SHM, use df to check memory allocation. (Thanks user11150436)

  The figure of "Mem used" in the upper part is the actual use of memory: shared memory and the library are not counted multiple. However, Linux always puts in cache (read before actually requested) and disk i/o buffer (writing after completion of signaling). Therefore, "Used Mem" is almost always of very nearly the amount of physical memory. "Used Mem' - 'buffers' - 'cached' reflects the memory actually used by the operating system and all the programs most accuately.

  And you can use the pmap utility to check the memory card. Can classify you the use of memory sharable and unsharable to calculate a more accurate result, adapted to your need. You need knowledge of OS to understand the output.

• 10.2.0.5 Oracle database link (Linux - x 86) for MS SQL Server 2012 (x 64)

  Please guys, I really need your help on this issue.

  I tried using freetds driver but when I use db link I get this error:

  ORA-28500: connection between ORACLE and a non-Oracle system has sent this message:

  [Generic connectivity using ODBC] [S1000] [9013] error General nvITrans_BeginT - rc = - 1. Please see the log file for more details.

  ORA-02063: preceding 2 lines MIXERI

  To cite that I can connect to the remote sql server through isql tool with no problem at all. I study a lot and I found no solution for this error, so to this end, I will try to find another alternative way.

  
  

  Is there another way to manage the communication link between the system of 2 DB db?

  Thank you

  Hello

  S erro coming from the ODBC side then you can try the following-

  1. change the listener.ora LD_LIBRARY_PATH for-

  (ENVS=LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/db/oracle/10.2.0/lib)

  stop and start the listener.

  2. don't you get the error even if you delete the entry-

  HS_FDS_SQLLEN_INTERPRETATION = 32

  3. get a debugging bridge route-

  -Comment the entry
  HS_FDS_TRACE_FILE_NAME = /db/oracle/10.2.0/hs/admin/MIKSERI.trc

  then the tracks go to the location by default with default names-

  /DB/Oracle/10.2.0/HS/log

  -set the level of the trace-

  HS_FDS_TRACE_LEVEL = DEBUG

  -start a new session of SQLPLUS, run select, close the session.

  -Download the trace from somewhere, it can be displayed by our care.

  It can also be an idea to install and use the 11.2.0.5 last DG4ODBC gateway that is certified with RDBMS 10.2.0.5 and available at My Oracle Support you.

• All parameter memory index for Oracle text indexes

  Hi Experts,

  I'm on Oracle 11.2.0.3 on Linux and have implemented Oracle Text. I'm not an expert in this area and need help on a question. I created the Oracle text index with the default setting. However, in a white paper of oracle, I read that the default setting is perhaps not good. Excerpt from the white paper by Roger Ford:

  URL:http://www.oracle.com/technetwork/database/enterprise-edition/index-maintenance-089308.html

  "(Part of this white paper below. )" ...)

  Index memory as mentioned above, $I entries cached emptied out on the disk each time the indexing memory is exhausted. The default index to installing memory is a simple 12MB, which is very low. At the time of creating indexes, users can specify up to 50 MB, but it is still quite low.                                   

  This would be by a CREATE INDEX, something like statement:

   CREATE INDEX myindex ON mytable(mycol) INDEXTYPE IS ctxsys.context PARAMETERS ('index memory 50M');  

  Allow index of the parameters of memory beyond 50 MB, the CTXSYS user must first of all increase the value of the MAX_INDEX_MEMORY parameter, like this:

   begin ctx_adm.set_parameter('max_index_memory', '500M'); end;  

  The parameter memory must never be high point causes paging, because this will have a serious effect on indexing speed. The smallest of dedicated systems, it is sometimes advantageous to temporarily reduce the amount of memory consumed by the Oracle SGA (for example by reducing DB_CACHE_SIZE and/or SHARED_POOL_SIZE) during the index creation process. Once the index has been created, the size of the SGA can be increased again to improve query performance. & quot;

  (End of the excerpt from the white paper)

  
  My question is:

  (1) to apply this procedure (ctx_adm.set_parameter) obliged me to log on as user CTXSYS. Is this fair? or can it be avoided and will be based on the application schema? The CTXSYS user is locked by default and I had to unlock it. Is this OK to do it in production?

  (2) what value I should use for the max_index_memory there are 500 MB - my SGA is 2 GB in Dev / QA and / 3 GB in the production. Also in the creation of the index which is the value should I set for the parameter memory index - I had left to default, but how do I change now? Should it be 50 MB as shown in the example above?

  (3) the white paper also refer to the reconstruction of an index to an interval like once a month: ALTER INDEX DR$ index_name$ X REBUILD online;

  -Is this good advice? I would like to ask the experts once before doing this.  We are on Oracle 11 g and the white paper was drafted in 2003.

  Basically, while I read the book, I'm still not clear on many aspects and need help to understand this.

  Thank you

  OrauserN

  Index entries are built in memory, and then flushed to disk, memory is exhausted. With a setting of high index memory will mean the index entries can be longer and less fragmented, which provides better performance of the query.  Conversely, a small memory parameter index will mean emptied the disk pieces are smaller, so queries (especially on common words) will have to do a lot more e/s to extract several pieces of index for the words.

• Options for Oracle GoldenGate and Oracle Data Guard

  Hello

  Hello

  3. no additional license required for Oracle Data Guard to install.

  Oracle GoldenGate:

  1 operating system in the primary database and the Standby Database are not necessarily even.

  2. major databases and standby are not necessarily even. (Including database software).

  3 oracle GoldenGate Software license required in the Source code and database is target.

• zip file to create diagrams for Oracle and Oracle Discoverer Portal

  Hello everyone.
  
  Im trying to install WebLogic for forms and reports under linux,
  I need the zip file to create diagrams for Oracle and Oracle Discoverer Portal
  to run the rcu scrip.
  
  Can someone send me the link where I can find it?
  
  Thanks to advanced & happy new year to all.

  If you are a developer of FMw 11 g installation, you need not configure the portal or the discoverer, unless of course you plan to use these products.

  When I installed and configured the FMw 11 g, I followed the * how to install Fusion Middleware 11 g forms and reports only [854117.1 ID] * (available via My Oracle Support). WLS and FMw share the Directory Home of Middleware. I accepted directories default installation (\Oracle\Middleware\) and WLS installed in \Oracle\Middleware\wlserver_10.3 and FMw installed at \Oracle\Middleware\Oracle_PFRD, and the Instance of forms at \Oracle\Middleware\instances\ft_inst. More Doc ID 854117.1, I chose only the following for installation in step "configure the components:
  

  
  
  • Server - Oracle Forms and Oracle reports components
    
  • Developer - Oracle Forms Builder and Oracle report builder tools
    
  • Management components - Enterprise Manager
    
  • The system - Oracle HTTP Server components
    

  IM thinking I have need save the fmx in a directory of this tree and also the FMAS and configure ther formsweb agreeing with that.

  It is not necessary. All you have to do is add the Variable environment of FORMS_PATH (EV) and include the directory where your files .fmb and .fmx will be created. This EV indicates forms where to find your forms Modules and libraries of forms (.pll/.plx) you can use in your forms.

  The usefulness of the repository creation (RCU), you can download it here: http://www.oracle.com/technetwork/middleware/downloads/fmw-11-download-092893.html
  Just scroll down for the * @ section additional software required and there is a separate download.
