Oracle 9iFS performance with WebService

Hello,
We use Oracle 9iFS with Oracle iAS and Oracle Database. We have implemented WebServices that use iFS API to upload/view/modify the documents in iFS. Even for a file that is ~5Mb, the performance is poor. Do we have any Benchmark testing results so that we can compare our results? We also get some Errors every now and then, which locks up the iFS instance and can only be solved by restarting the instance, the errors are like follows
oracle.ifs.common.IfsException: IFS-21008: Unable to connect to iFS service
oracle.ifs.common.IfsException: IFS-12214: Unable to get item in collection by name (CLASSOBJECT)
oracle.ifs.common.IfsException: IFS-12201: Unable to resolve collection
oracle.ifs.common.IfsException: IFS-20008: Unable to prepare query statement
java.sql.SQLException: Refcursor value is invalid
or
oracle.ifs.common.IfsException: IFS-21008: Unable to connect to iFS service
oracle.ifs.common.IfsException: IFS-21002: Unable to construct S_LibraryObject for class oracle.ifs.server.S_LibrarySession (unexpected Exception occurred in invoked method)
java.lang.Exception: java.lang.OutOfMemoryError
or
oracle.ifs.common.IfsException: IFS-21008: Unable to connect to iFS service
oracle.ifs.common.IfsException: IFS-20001: Unable to get schema version
oracle.ifs.common.IfsException: IFS-20000: Unable to get repository parameter (SCHEMAVERSION)
java.sql.SQLException: Bigger type length than Maximum
Are these errors because of - Not applying patches or some problem with concurrent iFS access. We have identified an issue with memory leak and are working to resolve it, but we feel that there maybe more issues. Any help would be appreciated, thanks

That depends on at least three things:
(1) what is the range of words that will appear in the document set (wide range of documents = smaller resultsets = better performance)
(2) how precise are the user's queries likely to be (more precise = smaller resultsets = better performance)
(3) how many milliseconds are your users willing to wait for results
So, unfortunately, you'll probably have to experiment a bit before you'll know...

Register the Oracle 9iFS Portlet with Oracle Portal

I did register the Oracle 9iFS Portlet with Oracle Portal.
But when I am adding the portlet to a portal page I get the error:
"500 Internal Server Error"
When I am trying to access the page by url:
http://<myserver>:7777/ifs/portlet
I get the error:
"You are not authorized to view this page"

not a problem with BEA , just means your database has been configured to close your session after a period of inactivity(which is normal).
Check you connection pool testing settings and tune accordingly.

Oracle 10g – Performance with BIG CONTEXT indexes

I would like to use Oracle XE 10.2.0.1.0 only for the full-text searching of the files residing outside the database on the FTP server.
Recently I have found out that size of the files to be indexed is 5GB.
As I have read somewhere on this forum before size of the index should be 30-40% of the indexed text files (so with formatted documents like PDF or DOC even less).
Lets say that the CONTEXT index size over these files will be 1.5-2GB.
Number of the concurrent user will be max. 5.
I can not easily test it my self yet.
Does anybody have any experience with Oracle XE or other Oracle Database edition performance with the CONTEXT index this BIG?
Will Oracle XE hardware resources license limitation be sufficient to handle one CONTEXT indexe this BIG?
(Oracle XE license limitations: 1 GB RAM and 1 CPU)

Oracle Database Performance With Semantic

Hello,
Is there a Developer's Guide for Semantic that specifically talks about database performance with the Semantic network/tables/indexes? We are having issues with performance the larger the semantic network becomes.
Any help or pointers would be appriciated.
Thanks
-MichaelB

Matt,
Thanks for your response. Here are the answers to the questions about our setup/environment.
1) Are you querying multiple models and/or a model + entailment? If so, are you using a virtual model and using the ALLOW_DUP=T query option?
A single model, no entailments. We attempted to use multiple models, and a virtual model (with ALLOW_DUP=T), however the UNION ALL in the explain plan made the query duration unacceptable.
2) Are you using named graphs?
No named graphs.
3) How many triples are you querying?
Approximately 85 million.
4) What semantic network and/or datatype indexes have been created?
We have PCSGM, PSCGM, PSCM, PCSM, CPSM, and SCM.
5) What is your hardware setup (number and type of disks, RAM, processor, etc.)?
We are running the 11.2.0.3 database on a Sun Solaris T2000, we have ASM managing our disks from RAID5, I believe currently we have two Disk Groups with the indexes in one and the data tables in the other. We have 32 GB of memory, and 32 CPUs. However, it is not the only thing running on the machine.
6) How much memory have you allocated to the database (pga, sga, memory_target, etc.)?
We have the memory_target set to 9GB, the db_cache_size set to 2GB, and the db_keep_cache_size set to 4.5GB. `pga_aggregate_target` is set to 0 (auto), as is `sga_target`.
(Since my initial request, we pinned the RDF_VALUE$ (~2.5GB) and C_PK_VID (~1.7GB) objects in the KEEP buffer cache, which drastically improved performance)
7) Are you using parallel query execution?
Yes, some of the more complex queries we run with the parallel hint set to 8.
8) Have you tried dynamic sampling?
Yes. We have ODS set to 3 for our more complex queries, we have not altered this much to see if there is a performance gained by changing this value.
Thanks again,
-Michael

Oracle Spatial Performance with 10-20.000 users

Does anyone have any experience when Oracle Spatial is used with say 20.000 concurrent users. I am not interested in MapViewer response time, but lets say there is:
- an app using 800 different tables each having an sdo_geometry column
- the app is configured with different tables visible on different view scales
- let's say an average of 40-50 tables is visible at any given time
- some tables will have only a few records, while other can hold millions.
- there is no client side caching
- clients can zoom in/out pan.
Anwers I am interested in:
- What sort of server would be required
- How can Oracle serve all that data (each Refresh renders the map and retrieves the data over the wire as there is no client side caching).
- What sort of network infrastructure would be required.
- Can clients connect to different servers and hence use load balancing or does Oracle have an automatic mechanism for that?
Thanks in advance,
Patrick

Patrick, et al.
There are lots of things one can do to improve performance in mapping environments because of a lot of the visualisation is based on "background" or read-only data. Here are some "tips":
1. Spatially sort read-only data.
This tip makes sure that data that is close to each other in space are next to each other on disk! Dan gave a good suggestion when he referenced Chapter 14, "Reorganize the Table Data to Minimize I/O" pp 580- 582, Pro Oracle Spatial. But just as easily one can create a table as select ... where sdo_filter() where the filtering object is an optimized rectangle across the whole of the dataset. (This is quite quick on 10g and above but much slower on earlier releases.)
When implementing this make sure that the created table is created such that its blocks are next to each other in the tablespace. (Consider tablespace defragmentation beforehand.) Also, if the data is READ ONLY set the PCTFREE to 0 in order to pack the data up into as small a number of blocks as possible.
2. Generalise data
Rendering spatial data can be expensive where the data is geometrically detailed (many vertices) esp where the data is being visualised at smaller scales than it was captured at. So, if your "zoom thresholds" allow 1:10,000 data to be used at 1:100,000 then you are going to have problems. Consider pre-generalising the data (see sdo_util.simplify) before deployment. You can add multiple columns to your base table to hold this data. Be careful with polygon data because generalising polygons that share boundaries will create gaps etc as the data is more generalised. Often it is better to export the data to a GIS which can maintain the boundary relationships when generalising (say via topological relationships).
Oracle's MapViewer has excellent on-the-fly generalisation but here one needs to be careful. Application tier caching (cf Bryan's comments) can help here a lot.
3. Don't draw data that is sub-pixel.
As one zooms out objects become smaller and smaller until they reach a point where the whole object can be drawn within a single pixel. If you have control over your map visualisation application you might want to consider setting the SDO_FILTER parameter "min_resolution" flag dynamically so that its value is the same as the number of meters / pixel (eg min_resolution=10). If this is set Oracle Spatial will only include spatial objects in the returned search set if one side of a geometry's MBR is greater than or equal to this value. Thus any geometries smaller than a pixel will not be returned. Very useful for large scale data being drawn at small scales and for which no selection (eg identify) is required. With Oracle MapViewer this behaviour can be set via the generalized_pixels parameter.
3. SDO_TOLERANCE, Clean Data
If you are querying data other than via MBR (eg find all land parcels that touch each other) then make sure that your sdo_tolerance values are appropriate. I have seen sites where data captured to 1cm had an sdo_tolerance value set to a millionth of a meter!
A corollary to this is make sure that all your data passes validation at the chosen sdo_tolerance value before deploying to visualisation. Run sdo_geom.validate_geometry()/validate_layer()...
4. Rtree Spatial Indexing
At 10g and above lots of great work went in to the RTree indexing. So, make sure you are using RTrees and not QuadTrees. Also, many GIS applications create sub-optimal RTrees by not using the additional parameters available at 10g and above.
4.1 If your table/column sdo_geometry data contains only points, lines or polygons then let the RTree indexer know (via layer_gtype) as it can implement certain optimizations based on this knowledge.
4.2 With 10g you can set the RTree's spatial index data block use via sdo_pct_free. Consider setting this parameter to 0 if the table/column sdo_geometry data is read only.
4.3 If a table/column is in high demand (eg it is the most commonly used table in all visualisations) you can consider loading (a part of) the RTree index into memory. Now, with the RTree indexing, the sdo_non_leaf_tbl=true parameter will split the RTree index into its leaf (contains actual rowid reference) and non-leaf (the tree built on the leaves) components. Most RTrees are built without this so only the MDRT*** secondary tables are built. But if sdo_non_leaf_tbl is set to true you will see the creation of an additional MDNT*** secondary table (for the non_leaf part of the rtree index). Now, if appropriate, the non_leaf table can be loaded into memory via the following:
ALTER TABLE MDNT*** STORAGE(BUFFER_AREA KEEP);
This is NOT a general panacea for all performance problems. One should investigate other options before embarking on this (cf Tom Kyte's books such as Expert Oracle Database Architecture, 9i and 10g Programming Techniques and Solutions.)
4.4 Don't forget to check your spatial index data quality regularly. Because many sites use GIS package GUI tools to create tables, load data and index them, there is a real tendency to not check what they have done or regularly monitor the objects. Check the SDO_RTREE_QUALITY column in USER_SDO_INDEX_METADATA and look for indexes with an SDO_RTREE_QUALITY setting that is > 2. If > 2 consider rebuilding or recreating the index.
5. The rendering engine.
Whatever rendering engine one uses make sure you try and understand fully what it can and cannot do. AutoDesk's MapGuide is an excellent product but I have seen it simply cache table/column data and never dynamically access it. Also, I have been at one site which was running Deegree and MapViewer and MapViewer was so fast in comparison to Deegree that I was called in to find out why. I discovered that Deegree was using SDO_RELATE(... ANYINTERACT ...) for all MBR queries while MapViewer was using SDO_FILTER. Just this difference was causing some queries to perform at < 10% of the speed of MapViewer!!!!
6. Consider "denormalising" data
There is an old adage in databases that is "normalise for edit, denormalise for performance". When we load spatial data we often get it from suppliers in a fairly flat or normalised form. In consort with spatial sorting, consider denormalising the data via aggregations based on a rendering attribute and some sort of spatial unit. For example, if you have 1 million points stored as single points in SDO_GEOMETRY.SDO_POINT which you want to render by a single attribute containing 20 values, consider aggregating the data using this attribute AND some sort of spatial BUCKET or BIN. So, consider using SDO_AGGR_UNION coupled with Spatial Analysis and Mining package functions to GROUP the data BY <<column_name>> and a set of spatial extents.
6. Tablespace use
Finally, talk to your DBA in order to find out how the oracle database's physical and logical storage is organised. Is a SAN being used or SAME arranged disk arrays? Knowing this you can organise your spatial data and indexes using more effective and efficient methods that will ensure greater scalability.
7. Network fetch
If your rendering engine (app server) and database are on separate machines you need to investigate what sort of fetch sizes are being used when returning data from queries to the middle-tier. Fetch sizes for attribute only data rows and rows containing spatial data can be, and normally are, radically different. Accepting the default settings for these sizes could be killing you (as could the sort_area_size of the Oracle session the application server has created on the database). For example I have been informed that MapInfo Pro uses a fixed value of 25 records per fetch when communicating with Oracle. I have done some testing to show that this value can be too small for certain types of spatial data. SQL Developer's GeoRaptor uses 100 which is generally better (but this one can modify this). Most programmers accept defaults for network properties when programming in ADO/ODBC/OLEDB/JDBC: just be careful as to what is being set here. (This is one of the great strengths of ArcSDE: its TCP/IP network transport is well written, tuneable and very efficient.)
8. Physical Format
Finally, while Oracle's excellent MapViewer requires data its spatial data to be in Oracle, other commercial rendering engines do not. So, consider using alternate, physical file formats that are more optimal for your rendering engine. For example, Google Earth Enterprise "compiles" all the source data into an optimal format which the server then serves to Google Earth Enterprise clients. Similarly, a shapefile on local disk to the application server (with spatial indexing) may be faster that storing the data back in Oracle on a database server that is being shared with other business databases (eg Oracle financials). If you don't like this approach and want to use Oracle only consider using a dedicated Oracle XE on the application server for the data that is read only and used in most of your generated maps eg contour or drainage data.
Just some things to think about.

Oracle: slow performance with SELECT using ojdbc14 and connection pooling

Hello,
i'm working hard the last days to solve a performance problem with our customer using a oracle 10g database. For testing I used our oracle 9.2.0.1.0 database which shows the same symptoms. All doing solved nothing: the performance while using this oracle is much slower than other databases. This result I cannot trust and so I need some advice. What is missing to improve the performance on the java side?
The webapplication I use runs fast on MySQL 4.x and SQLServer 2000, but on the above mentioned Oracle it was always 4 times slower. The webapplication uses a lot of simple SELECT-Statements without complicated joins and so on (because it should run on many different databases). Doing some days of creating tests within this webapplication, I was not able to find any entrance point for a change. All databases server I'm using, having only the default configurations after a common installation.
To reduce the complexity I wrote a simple java application with connection pooling using only the latest libraries from apache-commons(dbcp, pool), and the latest ojdbc14 for oracle 9.2.
First the results than the code: MySQL needed less than 1000 millisecond, SQLServer around 1000 milliseconds and Oracle over 2000 milliseconds. I stopped pooling and the results are for Oracle even worse: over 18000 milliseconds (mysql:2500, sqlserver:4100).
I changed the classes for Oracle and used the class oracle.jdbc.pool.OracleConnectionCacheImpl from the ojdbc14-library. No difference (around 100 milliseconds more or less).
The only Select-Statement works on this table, which has one index on HICTGID.
It contains 259 entrances.:
CREATE TABLE HIERARCHYCATEGORY (
HICTGID NUMBER (19) NOT NULL,
HICTGLEVEL NUMBER (10) NOT NULL,
HICTGEXTID NUMBER (19) NOT NULL,
HICTGEXTPARENTID NUMBER (19) NOT NULL,
HICTGNAME VARCHAR2(255) NOT NULL
);The application simply loops through this table using
SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?, but I always open a connection before this query and closes this connection afterwards. So I use the pooling as much as possible. That's all SQL I'm using.
 protected static DataSource setupDataSource(String sDriver, String sUrl, String sUser, String sPwd) throws SQLException {
 BasicDataSource ds = new BasicDataSource();
 ds.setDriverClassName(sDriver);
 ds.setUsername(sUser);
 ds.setPassword(sPwd);
 ds.setUrl(sUrl);
 // The maximum number of active connections:
 ds.setMaxActive(3);
 // The maximum number of active connections that can remain idle in the pool,
 // without extra ones being released, or zero for no limit:
 ds.setMaxIdle(3);
 // The maximum number of milliseconds that the pool will wait (when there are no available connections)
 // for a connection to be returned before throwing an exception, or -1 to wait indefinitely:
 ds.setMaxWait(3000);
 return ds;
 }I can switch by using external properties between three databases (oracle, mysql and sqlserver) and if I want I can switch pooling off. And all actions I'm interested are logged by Log4J.
 public static Connection getConnection() throws SQLException {
 Connection result = null;
 String sJdbcDriver = m_oJbProp.getString("jdbcDriver");
 String sJdbcUrl = m_oJbProp.getString("databaseConnection");
 String sJdbcUser = m_oJbProp.getString("dbUsername");
 String sJdbcPwd = m_oJbProp.getString("dbPassword");

 } else {

 if (log.isDebugEnabled()) {
 log.debug("ConnectionPooling false");
 try {
 Class.forName(sJdbcDriver);
 result = DriverManager.getConnection(sJdbcUrl, sJdbcUser, sJdbcPwd);
 } catch (ClassNotFoundException cnf) {
 log.error("Exception: Class Not Found. ", cnf);
 System.exit(0);

 rsInner.close();
 con.close();
 lNextBottom++;
 if (log.isInfoEnabled()) {
 log.info("\rResult values: Hictgid, Hictgname \r");
 log.info(sb.toString());
 }and the main method:

 if (null != m_ds) {
 printDataSourceStats(m_ds);
 shutdownDataSource(m_ds);
 if (log.isInfoEnabled()) {
 log.info("Datasource closed.");
 } catch (SQLException sqe) {
 log.error("SQLException within main-method", sqe);

A few comments.
There is of course another difference between your test cases then just the database. There is also the driver. And I suspect that in at least the case with the jtds driver it is helping you along where you are doing something silly and the Oracle driver is not.
Before I explain the next part I would say the speed differences between MS-SQL and MySQL look about right I think you are aiming here for MS-SQL level performance not MySQL. (For a bunch of reasons MySQL is inherently faster but there are MANY drawbacks as well which have been well discussed on previous threads)
Here is where I believe your problem lies
while (lNextBottom <= lNextCeiling) {
 con = getConnection();
 innerSelStmt = con.prepareStatement("SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?");
 innerSelStmt.setLong(1, lNextBottom);
 rsInner = innerSelStmt.executeQuery();
 if ((rsInner != null) && (rsInner.next())) {
 sb.append(rsInner.getLong(1) + ", " + rsInner.getString(2) + "\r");
 if (log.isDebugEnabled()) {
 log.debug("Inner Statement: " + rsInner.getLong(1) + "\r");
 rsInner.close();
 con.close();
 lNextBottom++;
 }There at least four things that are wrong with above.
1) Why are you preparing the statement INSIDE the loop. Let us for a moment say that the loop will spin 100 times. That means that you are preparing the same statement 100 times. This is bad. It is also very relevant because for example the Jtds driver is going to be caching the prepared statements you make so that actually while you try and prepare it 100 times it only actually does it once... but in Oracle I don't know what it is doing for sure but if it is preparing on each pass well than that bit of it is going take 100 times longer then it should.
2) You are opening and closing the connection on each pass through the loop... also a terrible idea. You need to fix this first so that you can repeatedly use the same prepared statement.
3) Why are you looping in the first place? More on this later.
4) Where do you close the PreparedStatement? It doesn't look like you do.
Okay so for starters your loop should look a lot more like this...
code]
con = getConnection();
innerSelStmt = con.prepareStatement("SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?");
while (lNextBottom <= lNextCeiling) {
innerSelStmt.setLong(1, lNextBottom);
rsInner = innerSelStmt.executeQuery();
if ((rsInner != null) && (rsInner.next())) {
sb.append(rsInner.getLong(1) + ", " + rsInner.getString(2) + "\r");
rsInner.close();
lNextBottom++;
innerSelStmt.close();
con.close();
I think the code above (and you can put your debug stuff back if you want) which uses ONE connection and ONE prepared Statement will improve your performance dramatically.
The other question though I would as is why in the hell you are doing 100 or whatever number of queries anyway. This can be done all in ONE query which again will improve performance.
Your query and such should look like this I think.
String sql = "SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID >=? AND HICTGID<=?";
PreparedStatement ps = conn.prepareStatement(sql);
ps.setLong(1,lNextBottom );
ps.setLong(2,lNextCeiling);
ResultSet rs = ps.executeQuery();
while(rs.next()){
// your appending to string buffer code goes here
}and I can't understand why you're not doing that in the first place.

Oracle text performance with context search indexes

Search performance using context index.
We are intending to move our search engine to a new one based on Oracle Text, but we are meeting some
bad performance issues when using search.
Our application allows the user to search stored documents by name, object identifier and annotations(formerly set on objects).
For example, suppose I want to find a document named ImportSax2.c: according to user set parameters, our search engine format the following
search queries :
1) If the user explicitely ask for a search by document name, the query is the following one =>
 select objid FROM ADSOBJ WHERE CONTAINS( OBJFIELDURL , 'ImportSax2.c WITHIN objname' , 1 ) > 0;
2) If the user don't specify any extra parameters, the query is the following one =>
 select objid FROM ADSOBJ WHERE CONTAINS( OBJFIELDURL , 'ImportSax2.c' , 1 ) > 0;
Oracle text only need around 7 seconds to answer the second query, whereas it need around 50 seconds to give an answer for the first query.
Here is a part of the sql script used for creating the Oracle Text index on the column OBJFIELDURL
(this column stores a path to an xml file containing properties that have to be indexed for each object) :

Oracle XE 10.2.0.1.0 – Performance with BIG full-text indexes

I would like to use Oracle XE 10.2.0.1.0 only for the full-text searching of the files residing outside the database on the FTP server.
Recently I have found out that size of the files to be indexed is 5GB.
As I have read somewhere on this forum before size of the index should be 30-40% of the indexed text files (so with formatted documents like PDF or DOC even less).
Lets say that the CONTEXT index size over these files will be 1.5-2GB.
Number of the concurrent user will be max. 5.
Does anybody have any experience with Oracle XE performance with the CONTEXT index this BIG?
(Oracle XE license limitations: 1 GB RAM and 1 CPU)
Regards.

I have used the 100% same configuration as above, but now for the Oracle Database 11g R1 11.1.0.7.0 – Production instead of Oracle 10g XE.
The result is that AUTO_FILTER for Oracle 11g is able to parse Czech language characters from the sample PDF file without any problems.
The problem with Oracle Text 10g R2 may be I guess:
1. In embedded fonts as mentioned in the Link: [documentation | http://download-west.oracle.com/docs/cd/B12037_01/text.101/b10730/afilsupt.htm] (I tried to embbed all fonts and the whole character set, but it did not helped)
2. in the character encoding of the text within the PDF documents.
I would like to add that also other third party PDF2Text converters have similar issues with the Czech characters in the PDF documents – after text extraction Czech national characters were displayed incorrectly.
If you have any other remarks, ideas or conclusions please reply :-)

Performance issues with Webservices in XI

Hi,
Friends,
my issue is with the performance of webservices.how to improve performance of webservices in XI?
We don't have any hardware issues.no big mapping or payload.webservice is actually residing in the XI server.there is a bottleneck somewhere which is hampering the performance.
Any advice is greatly appreciated!
Thanks and Regards,
Pavan M.
Chicago,US

Hi,
Is XI a webservice provider or consumer?
If XI is the consumer, then you can use any SOAP client tool (there are lots of generic 3rd party soap client test tools on the internet) to execute the webservice to detemine whether it is causing performance problem.
If XI is the provider, you can take the sender soap adapter out of the equation by using a HTTP client test tool.
The SXI_MONITOR also provides execution time for every step in the pipeline of the XI engine.
Regards,
Bill

Non jdriver poor performance with oracle cluster

Hi,
we decided to implement batch input and went from Weblogic Jdriver to Oracle Thin 9.2.0.6.
Our system are a Weblogic 6.1 cluster and an Oracle 8.1.7 cluster.
Problem is .. with the new Oracle drivers our actions on the webapp takes twice as long as with Jdriver. We also tried OCI .. same problem. We switched to a single Oracle 8.1.7 database .. and it worked again with all thick or thin drivers.
So .. new Oracle drivers with oracle cluster result in bad performance, but with Jdriver it works perfectly. Does sb. see some connection?
I mean .. it works with Jdriver .. so it cant be the database, huh? But we really tried with every JDBC possibility! In fact .. we need batch input. Advise is very appreciated =].
Thanx for help!!

Thx for quick replys. I forget to mention .. we also tried 10g v10.1.0.3 from instantclient yesterday.
I have to agree with Joe. It was really fast on the single machine database .. but we had same poor performance with cluster-db. It is frustrating. Specially if u consider that the Jdriver (which works perfectly in every combination) is 4 years old!
Ok .. we got this scenario, with our appPage CustomerOverview (intensiv db-loading) (sorry.. no real profiling, time is taken with pc watch) (Oracle is 8.1.7 OPS patch level1) ...
WL6.1_Cluster + Jdriver6.1 + DB_cluster => 4sec
WL6.1_Cluster + Jdriver6.1 + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_cluster => 8-10sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_single => 4sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_cluster => 8sec
WL6.1_Cluster + Ora10.1.0.3 thin + DB_single => 2-4sec (awesome fast!!)
WL6.1_Cluster + Ora10.1.0.3 thin + DB_cluster => 6-8sec
Customers rough us up, because they cannot mass order via batch input. Any suggestions how to solve this issue is very appreciated.
TIA

else. I would try the latest
10g driver if it will work with your DBMS version.
It's much faster than any 9.X
thin driver.

How to improve Oracle Veridata Compair pair performance with tables that have big (30-40MB)CLOB/BLOB fileds ?

How to improve Oracle Veridata Compair pair performance with tables that have big (30-40MB)CLOB/BLOB fileds ?

Can you use insert .. returning .. so you do not have to select the empty_clob back out.
[I have a similar problem but I do not know the primary key to select on, I am really looking for an atomic insert and fill clob mechanism, somone said you can create a clob fill it and use that in the insert, but I have not seen an example yet.]

Error in WebDynpro with WebServices

Hi all,
Im getting some errors using applications deployed in WEB AS SP9 that runs as a WebDynpro IView in EP.
Running the application as standalone (out of EP) this works fine.
NetWeaver Developer Studio 2.0.9
WebDynpro application using WebServices that access Oracle 8i database in the follow sequence:
WebServices -> Session Bean stateless -> Entity Bean CMP (manage connections; generate sql code, etc.)
In WebDynpro application we import WebService Model by the follow sequence:
New Model - Import Web Service Model - Local Server for WSDL Source - <WebService deployed>
In each WebServices we have created these methods:
findByID(ID);
getAll();
insert(parameters);
remove(ID);
update(parameters);
We guess that the error is generated in Entity Bean because all WebServices generate these errors.

Hi,
I feel this error is nothing to do with webservice model.
Please check your application properties like startupPlug,Interface View etc. Set the properties correctly and deploy once again.

Oracle Mobile Server with SQLLite/Berkeley Db and dbsql

Hi all,
i am not sure if i am correct here but hopefully i am.
In the past we have had Oracle Mobile Server with Oracle Lite.
We decided to switch to new mobile Server because oracle webtogo is not longer supported and incompatible with windows 7. My administrator did migration of mobile server but migration utility reported that the available applications are incompatible.
So I decided to create a completely New Publication with a Java application. The new Publication contains only one publication Item. For the first tests I simply wanted to spool out the data contained in my local database.
In bin directory of sqlite folder i can find a utility named "dbsql". I understood it in this way that I can attach to an existing database file and take a look into that database.
If i call dbsql.exe BerkeleyTest all seems to be ok. But if i try to select some data from that file i only get the errormessage that databse is in wrong format or encrypted. What am i doing wrong there?
Am I right that the sql interface (I need that interface because I dont want to rewrite dataaccesslayer of my app) is only available in sqlite but not on "BerkeleyDb"?
Is anyone here to help me a little bit with my problem here?
Regards!
Martin

I do not know much about Oracle Mobile Server with Oracle Lite, does it use SQLite or BDB? I do know that databases created by SQLite cannot be read by Berkeley DB SQL (of which dbsql.exe is part of), and databases created by Berkeley DB SQL cannot be read by SQLite. Also, databases created by Berkeley DB outside of the SQL API cannot be read by the BDB SQL API. You can open BDB SQL databases with BDB outside of the SQL API, but I would not recommend that outside of a few BDB utilities described in the documentation. So if your BerkeleyTest database was created by SQLite or BDB outside of the SQL API, then it makes sense that dbsql.exe is returning an error when trying to read it.
Calling dbsql.exe BerkeleyTest does not open the database, that happens when the first operation is performed on it, which is why you did not get an error until you tried to select something.

Generic connector with webservice and SPML provider

Hi,
I have created a Generic connector in Oracle Identity server successfully with Webservice transport porvider and SPML payload provider. But when I am trying to create a user using this connector I am getting following error in OIM server log:
AJPRequestHandler-RMICallHandler-20 XELLERATE.WEBAPP - Setting the response code as GCPROV.ProvTransportProvider.WebServices.Caught exception while handling request: malformed array t
Can anyone please help me regarding this? I am even not able to identify where it is getting failed.
Thanks in advance

This is what I've found in the docs:
"Each SPML request is sent in a SOAP message. The SOAP header carries authentication information for the request. The actual SPML request data is the SOAP message body. "
All I'm trying to do is create a SOAP web service (in this case with Java 6, but that's not fundamental) that can intercept that message and grab the SPML request (and then do what I have to do).
I tried with something like the following code:
package wsspml;
import javax.jws.WebService;
import java.io.IOException;
import java.util.logging.*;
@WebService
public class SPMLServer {
public String processRequest(String requestData) {
but it won't work. It's like the exposed SOAP method "processRequest" is invisible. It's not being called. Perhaps the signature is wrong. I don't know what to make of it. I'm trying to understand how to grab that SPML request that's coming from OIM through the custom generic technology connector that I configured.

Spatial Performance with join

I have a Oracle Spatial table with 3.5 million rows plus another auxillary table with 3.5 million rows. A query over these two tables joined returns a full result (250 rows) based on one to one join - here's an example:
Select count(*)
from F, N
where F.id = n.id and (F.GEOM,mdsys.sdo_geometry (2003,8307, null, mdsys.sdo_elem_info_array (1,1003,1), mdsys.sdo_ordinate_array(-120.0,49.5,-119.0,49.5,-119.0,60.35,-120.0,60.35,-120.0,49.5)),
'mask= ANYINTERACT querytype=WINDOW') = 'TRUE') AND N.PNUM = '4';
It takes an average of 35 seconds to get the full result set back. I've gathered statistics, tweaked memory parameters and this is the best I can get. Does anyone have any suggestions?

This is an interesting problem. It looks like Oracle is doing the right thing for each of the table accesses - use the index and fetch by rowid.
The only thing you have to play with if you don't go to materialized views or temp tables is how the results of the two table queries are joined.
You don't have a lot of options. Hash join seems to be slow, but you don't know if it is faster or slower compared with nested loops or merge join.
I'd compare what you have done with something like the following to test nested loops:
select /*+ no_merge use_nl (f1,n1) */ count(*)
from
(select id
from f
where sdo_anyinteract ( F.GEOM,
sdo_geometry (2003,8307, null, sdo_elem_info_array (1,1003,1),
sdo_ordinate_array (-120.0,49.5,-119.0,49.5,-119.0,60.35,
-120.0,60.35,-120.0,49.5))) = 'TRUE') f1,
(select id
from n
where n.pnum='4') n1
where f1.id=n1.id ;
and presort with a merge join hint to see how it performs:
select /*+ no_merge use_merge (f1,n1) */ count(*)
from
(select id
from f
where sdo_anyinteract ( F.GEOM,
sdo_geometry (2003,8307, null, sdo_elem_info_array (1,1003,1),
sdo_ordinate_array (-120.0,49.5,-119.0,49.5,-119.0,60.35,
-120.0,60.35,-120.0,49.5))) = 'TRUE'
order by id) f1,
(select id
from n
where n.pnum='4'
order by id) n1
where f1.id=n1.id ;
It might be that you already have the best Oracle can do, but I'd be curious to know how you make out.
