Postgresql
I am unable to get StarOffice on solaris x86 to recognize the postgresql sdbc driver to connect with PostgreSQL. I have not found a way to connect with the database. Does anyone know how to successfully connect StarOffice 8 (update 7) with PostgreSQL that comes with Solaris 10/11?
thanks,
Hi,
you need to edit config/data-sources.xml to use postgreSQL as a datasource by adding the following lines to that file besides installing PostgreSQL.
<data-source
name="Default data-source"
class="com.evermind.sql.ConnectionDataSource"
location="jdbc/DefaultDS"
pooled-location="jdbc/DefaultPooledDS"
xa-location="jdbc/xa/DefaultXADS"
ejb-location="jdbc/DefaultEJBDS"
schema="database-schemas/postgresql.xml"
url="jdbc:postgresql://localhost/ejb"
connection-driver="org.postgresql.Driver"
username="user"
password="pass"
/>
and substituting the correct hostname in place of "localhost", database name in place of "ejb", username in place of "user", and password in place of "pass" for your system.

Performance problems when running PostgreSQL on ZFS and tomcat
Hi all,
I need help with some analysis and problem solution related to the below case.
The long story:
I'm running into some massive performance problems on two 8-way HP ProLiant DL385 G5 severs with 14 GB ram and a ZFS storage pool in raidz configuration. The servers are running Solaris 10 x86 10/09.
The configuration between the two is pretty much the same and the problem therefore seems generic for the setup.
Within a non-global zone Im running a tomcat application (an institutional repository) connecting via localhost to a Postgresql database (the OS provided version). The processor load is typically not very high as seen below:
NPROC USERNAME SWAP RSS MEMORY TIME CPU
49 postgres 749M 669M 4,7% 7:14:38 13%
1 jboss 2519M 2536M 18% 50:36:40 5,9%We are not 100% sure why we run into performance problems, but when it happens we experience that the application slows down and swaps out (according to below). When it settles everything seems to turn back to normal. When the problem is acute the application is totally unresponsive.

My suspicion is currently focused on PostgreSQL. Turning off fsync boosted performance and made the problem less often to appear.
An unofficial performance evaluation on the database with vacuum analyze took 19 minutes on the server and only 1 minute on a desktop pc. This is horrific when taking the hardware into consideration.
The short story:
Im trying different steps but running out of ideas. Weve read that the database block size and file system block size should match. PostgreSQL is 8 Kb and ZFS is 128 Kb. I didnt find much information on the matter so if any can help please recommend how to make this change
Any other recommendations and ideas we could follow? We know from other installations that the above setup runs without a single problem on Linux on much smaller hardware without specific tuning. What makes Solaris in this configuration so darn slow?
Any help appreciated and I will try to provide additional information on request if needed
Thanks in advance,
Kasperraidz isnt a good match for databases. Databases tend to require good write performance for which mirroring works better.
Adding a pair of SSD's as a ZIL would probably also help, but chances are its not an option for you..
You can change the record size by "zfs set recordsize=8k <dataset>"
It will only take effect for newly written data. Not existing data. -
Using PostgreSQL through a DB Link connection
Hi,
I'm trying to connect to PostgreSQL using a DB Link connection but when retrieving the users in the Discoverer Administrator after selecting the Database Link I got the following error: Database Error - ORA - 00904: "USERNAME" invalid identifier. It seems that Discoverer is not able to execute a correct Data Dictionary query against PostgreSQL so the users (in this case) are not correctly listed. Is there any configuration option in Oracle Discoverer or DB Link parameter that I can use in order to make it work? What would be your recommendation in this case? Are PostgreSQL and Oracle Discoverer compatible?
Thank you very muchHi,
I would always recommend that you use database views in situations like this. Then the metadata is held in the Oracle database and you will have no issues importing these views into Discoverer.
So create a schema in your database and in this schema create a view for each PostgreSQL table you want to use, for example, CREATE VIEW myview as SELECT * FROM pgtable@dblink. You can use a script to bulk create the views.
If you want, You can set up primary key and foreign key constraints on these views so that the joins are automatically created when the views are imported into Discoverer. Also the security is much better with views as you only need a private db link and then grant selects on your views to other database users.

Configuring DBAT 9.1.0.5 connector with PostgreSQL database in OIM 11g
Hi,
I am trying to configure the DBAT 9.1.0.5 connector with PostgreSQL database in OIM 11g (11.1.1.5.0), thou' in the connector document the suppot for this postgres is not mentioned.
So, as mentioned for other databases that the JDBC driver has to be copied to $JAVA_HOME/jre/lib/ext, I have also copied the postgres driver to the specific folder but while trying to configure the connector, I am getting the error as 'No suitable driver found'. Following is the stacktrace snippet.

I am using postgresql-8.4-703.jdbc4.jar and Driver class as org.postgresql.Driver
some suggestions on this would be highly appreciated.
Thanks
SidThanks guys for the quick responses.
But I have tried both the options for putting the jar in Third Party and also by uploading using the OOTB utility UploadJar.sh.
But it is giving the same error.
I have tired rebouncing the server and also Purge cached, but no success.
Just to mention again, I have tried with all the last 3 postgres JDBC4 driver available on the site (u mentioned).
So, any other clue?
Thanks in advance. -
[SOLVED] Postgis no longer working after upgrade of postgresql
Dear all,
after yesterdays upgrade of postgresql-server and libs to 9.0.1 the postgis package does no longer work. When trying to import postgis.sql (version 1.5) it always complains about wrong libraries version:
psql:/usr/share/postgresql/contrib/postgis-1.5/postgis.sql:59: FEHLER: inkompatible Bibliothek »/usr/lib/postgresql/postgis-1.5.so«: Version stimmt nicht überein
I have double checked on postgresql and postgis documents that the versions should be compatible:
postgresql 9.0.1-2
postgresql-libs 9.0.1-2
postgis 1.5.1-1
For all databases dump and restore was fine, except for my gis databases. So upgrade from 8.4.4 to 9.0.1 worked in general.
Any ideas?
Last edited by Wauzenplauz (2010-10-31 14:46:20)"Unfortunately" I did not have enough time to give it a try and rebuild the package.
So today I found that there is already a new version of postgis available which works perfectly fine! -
JDeveloper 10.1.2 with MySQL and PostgreSQL
I'm testing JDeveloper 10.1.2 business components with mysql or postgresql because my company needs to connect also to these non-oracle DBs. ADF suits our developement needs, in speed and functionalities; anyway to make it our main developement system we need it to be compatible.
I made three tests and they were all disappointing.
At first, I installed MySQL 4.0 on my windows machine. I used the stable Connector/J 3.1
and then MySQL Connector/J 3.0, but in both cases JDeveloper had a strange behaviour: I can make the connection, I can navigate correctly through all tables in the connection-navigator, I see all the column names etc... Anyway, as I try to build a "new Entity Object" from a table, there are no available table properties, like if the table had no columns.
In this forum I only found documentation about rowid problems with mysql, but nothing about Entity Object wizard issues.
Then I switched to PostgreSQL. I installed it locally, so I had to choose the 8.01 since I'm on a windows machine. JDBC driver: postgresql-8.0-310 jdbc3
The developement test phase went ok, it is possible to use this DB just as if it was a Oracle, all the business components wizards works perfectly.
The problem is at runtime, unfortunately. I built a simple datapage on the struts-config diagram and I dragged on it a "read-only table" from the data control palette.
As I run the application, the embedded OC4J immediately returns this error:
oracle.jbo.JboException: JBO-29000: JBO-29000: JBO-29000: JBO-26061: Errore durante lapertura della connessione JDBC.
at oracle.jbo.JboException.<init>(JboException.java:343)
(in english: Error during JDBC connection)
There are no other available JDBC drivers for JVM 1.4x so I see no solution...
I also tried to connect to an older PostgresSQL with its (older) JDBC but I get same the result.
Anyone can help? Is it a JDev 10.1.2 issue?Hi Paolo.
I'm also doing such tests.
I did not ran into these problems because I created the busisness componentes using an Oracle connection first.
After that, I switched the datatype of the table columns in the entity object to meet the SQL92 criteria ( like changing NUMBER(n) to INTEGER ).
And then, I switched the connection to the postgreSQL or MySQL. This worked fine for me.
But, the other big problem you will face is related to updating records using postgreSQL connection.
Please see my post "Problem updating records using BC4J with foreign data sources" Problem updating records using BC4J with foreign data sources
It would by fine if we help each other to solve this problems.
Thanks

Configuration of PostgreSQL in Solaris 10
I really having problems in configuring postgreSQL in my desktop...
When i execute the initdb command it display this error:
The user must own the server process.
thanxyou have to be user postgres to use that command. if you are your regular user or root it won't work.
so become root and type:
su - postgres
then type your command initdb (with whatever appropriate arguments) and it should work and initialize your database cluster. -

Thank you.When looking at the strace file the Driver Manager tries to load the odbc.ini you specified in your gateway init file: set ODBCINI=/etc/odbc.ini
but that fails as the oracle user can not access it - instead it tries to load a different file:
17811 open("/etc/odbc.ini", O_WRONLY|O_CREAT|O_APPEND, 0666) = -1 EACCES (Permission denied)
17811 open("/usr/local/unixodbc/etc/odbc.ini", O_RDONLY) = 8
Could you please make sure that the oracle user can access that file?
You also mentioned at the beginning that you could connect to the Postgres database using isql - did you do the test as "oracle" user and what ENV parameters have you set before opening isql?
Just a minor issue which has no impact as your LD_LIBRARY_PATH in the environment is set correctly - the listener.ora file contains the line
(EVNS=LD_LIBRARY_PATH=/usr/local/unixodbc/lib:/usr/local/pgsqlodbc/lib:/u01/app/oracle/product/11.2.0/dbhome_1/bin)
but EVNS should be ENVS or even better ENV. So please correct:
(EVNS=LD_LIBRARY_PATH=/usr/local/unixodbc/lib:/usr/local/pgsqlodbc/lib:/u01/app/oracle/product/11.2.0/dbhome_1/bin)
to
(ENV="LD_LIBRARY_PATH=/usr/local/unixodbc/lib:/usr/local/pgsqlodbc/lib:/u01/app/oracle/product/11.2.0/dbhome_1/bin")
Then stop and start the listener.

Huge pauses in accept/fork server (postgresql) on 96GB S10 server
Hi,
We are deploying new hardware for our Solaris 10 Postgresql server and have stumbled onto a very confusing problem. This doesn't appear to be an obvious system limit issue, but something more complex.
The new server is:
dual Intel, four cores each, total of 16x threads w/hyperthreading enabled
96GB memory
60+ drives in several ZFS pools with cache and ZiL devices
Running Postgresql 8.2.21, 32bit binaries (which is a requirement)
Solaris 10 x64 at latest patchlevel
Default system settings
On the new server, when we attempt a connection to Postgresql, the main server process takes a very long time to accept & fork the child server process; several seconds rather than the usual 10+ milliseconds. The accept queue is processed at a glacial pace, rendering Postgresql completely unusable. During this time there are no errors from the operating system or the application and vmstat appears normal.
Now for the confusing part: Proc tools don't work
While the Postgresql process is not accepting/forking a child process, it is normal and observable using tools like truss, pstack, pmap, pfiles... However, when we attempted a pstack of the Postgresql daemon during the connect/accept/fork "hang", the pstack invocation hung for several seconds and returned no information except the PID and command-line information. A truss invocation also hung for several seconds, finally outputing a very slow stream of normal-looking output. When we gcore'd the process and tried looking at in gdb, there were only messages about address at zero, nothing to make sense of.
We lowered the Postgresql shared memory from 1500MB to 700MB and the problem stopped. We whittled down the SHM size to working/non-working sizes, but they seemed to fluctuate. We have other servers that run these amounts of shared memory without issue. Given the fluctuation, we are hesitant to assume that there is ANY shared memory size that is reliable until we understand the problem.
Now for the more confusing part: DTrace fixes the problem, at least while it is running
We tried DTraceToolkit scripts to examine the PG process. As soon as we invoked dapptrace on the PID, connections began flowing, albeit at a pace that you would expect from a DTrace'd process. When we CTRL-C'd from the DTrace script and re-attempted to connect, the problem would return. By running dapptrace or another DTrace script, we could un-stick the Postgresql server process at will and bring it back by exiting the script.
Now for the even more confusing part: Less memory is better, twice the apps is better still
* We tried an identical, in every respect, server and could reproduce the condition
* We tried an identical server, except with only 48GB memory, and could NOT reproduce the problem
* We accidentally started two Postgresql processed with 1800MB shared memory each, but ONLY THE
FIRST server was affected. Subsequent servers are not affected.
* Trying to replicate the "sacrificial" server setup, we wrote a program to allocate shared memory and
semaphores similar to a Postgreql process, then started a Postgresql process. The did not avoid the
problem for the server, which we didn't expect. Perhaps we didn't perfectly recreate the scenario.
The big questions:
* What would oddly hang during fork with SHM?
* Why would we hit this problem at 96GB memory but not 48GB?
* Why would a DTrace script alter the condition for the better?
* Why would one Postgresql process suffer the problem but not subsequent processes?
Any help would be greatly appreciated.The problem seems to be related to or manifested in fork(). The forked process resumes immediately, but the forking process hangs for a great deal of time.
The following is the code that is run, slightly abbreviated. "child done" takes zero seconds, but "parent done" has taken between zero and 42 seconds.
int result;
time_t start,end;
start = time()
result = fork();
end = time(NULL);
if (result == 0)
elog(INFO,"fork_process:child done, %d", end - start);
else
elog(INFO,"fork_process:parent done, %d", end - start);

Pleas tell me that where I have done the mistake and how can I resolove the error.ahmadgee wrote:
Thank u very much.
First I tried with out the servlet. I took a simple class. But it was displaying the null pointer exception.
then you still have the problem. do you understand the root cause?
After then I made a servlet. how was that going to help your null pointer exception?
Now it is displaying error hibernate.cfg.xml not found.that's part of the problem. where is the servlet reading that file and initializing the session factory? how is it finding that file?
i don't know where you have that .cfg.xml file, or where the recommended place is where hibernate expects to see it, but i'd bet it needs to be in the CLASSPATH, which means WEB-INF/classes.
figure out why you get that NPE first, though. the servlet is only making things worse.

Bug while using string parameter values in postgresql query
Hi,
I have the following query for the postgresql database:
Code:
<queryString><![CDATA[SELECT
evt_src_mgr_rpt_v."evt_src_mgr_name" AS esm_name,
evt_src_collector_rpt_v."evt_src_collector_name" AS collector_name,
evt_src_grp_rpt_v."evt_src_grp_name" AS grp_name,
evt_src_grp_rpt_v."state_ind" AS state_ind,
evt_src_rpt_v."evt_src_name" AS src_name,
evt_src_rpt_v."date_modified" AS date_modified,
evt_src_rpt_v."date_created" AS date_created,
CASE WHEN $P{mysortfield} = 'evt_src_mgr_name' THEN evt_src_mgr_name
WHEN $P{mysortfield} = 'evt_src_collector_name' THEN evt_src_collector_name
WHEN $P{mysortfield} = 'evt_src_grp_name' THEN evt_src_grp_name
ELSE evt_src_name END as sort
FROM
"evt_src_mgr_rpt_v" evt_src_mgr_rpt_v
LEFT JOIN
"evt_src_collector_rpt_v" evt_src_collector_rpt_v
ON EVT_SRC_MGR_RPT_V."evt_src_mgr_id" = evt_src_collector_rpt_v."evt_src_mgr_id"
LEFT JOIN
"evt_src_grp_rpt_v" evt_src_grp_rpt_v
ON evt_src_collector_rpt_v."evt_src_collector_id" = evt_src_grp_rpt_v."evt_src_collector_id"
LEFT JOIN
"evt_src_rpt_v" evt_src_rpt_v
ON evt_src_grp_rpt_v."evt_src_grp_id" = evt_src_rpt_v."evt_src_grp_id"
LEFT JOIN
"evt_src_offset_rpt_v" evt_src_offset_rpt_v
ON evt_src_rpt_v."evt_src_id" = evt_src_offset_rpt_v."evt_src_id"
WHERE
$P!{mysortfield} LIKE '$P!{searchvalue}' || '%']]></queryString>
That is I try to select only the records where the field which is
selected by user as report parameter ($P{mysortfield}) contains data
starting with the text entered by user as a report parameter
($P{searchvalue}).
When I try to run the report in iReport with active connection to the
database the report is generated as expected.
But when I try to run the report from Sentinel Log Manager I get the
following error: "java.lang.String cannot be cast to
net.sf.jasperreports.engine.JRValueParameter".
After several detailed debug sessions I finally came into a conclusion
that this error is related to the use of parameter values (
$P!{mysortfield} and $P!{searchvalue} ).
I even tried using the following WHERE clause (which emulates the
queries as used in standart reports (especially at VendorProduct related
SQL queries ) with no success:
Code:
WHERE
($P{mysortfield} = 'evt_src_mgr_name' AND evt_src_mgr_name LIKE ($P{searchvalue} || '%')) OR
($P{mysortfield} = 'evt_src_collector_name' AND evt_src_collector_name LIKE ($P{searchvalue} || '%')) OR
($P{mysortfield} = 'evt_src_grp_name' AND evt_src_grp_name LIKE ($P{searchvalue} || '%')) OR
($P{mysortfield} = 'evt_src_name' AND evt_src_name LIKE ($P{searchvalue} || '%'))
Any suggestions?

Thank you for the suggestions:
While trying to implement your suggestions I realized that there was a
error at the parameter name I used inside the where clause (it should be
$P{searchfield}).
Here are my results:
Code:
vt_src_mgr_name LIKE '%' || '%'
worked as expected.
Code:
$P{searchfield} LIKE '%' || '%'
produced PDF but wrong output.
Code:
$P!{searchfield} LIKE '%' || '%'
resulted with the error "java.lang.String cannot be cast to
net.sf.jasperreports.engine.JRValueParameter" and no PDF.
Then I tried the following where clause which resulted in exactly as
expected PDF:
Code:
WHERE
($P{searchfield} = 'evt_src_mgr_name' AND evt_src_mgr_name LIKE ($P{searchvalue} || '%')) OR
($P{searchfield} = 'evt_src_collector_name' AND evt_src_collector_name LIKE ($P{searchvalue} || '%')) OR
($P{searchfield} = 'evt_src_grp_name' AND evt_src_grp_name LIKE ($P{searchvalue} || '%')) OR
($P{searchfield} = 'evt_src_name' AND evt_src_name LIKE ($P{searchvalue} || '%'))
As a summary:
* The query which works in iRepord do not work in Sentinel Log
Manager.
* I found a workaround for my case.
* I did not checked, but the reports provided in Sentinel RD which use
the same technique for VendorProduct parameter (i.e. the reports with
query string containing
Code:
LIKE ($P{VendorProduct} || '%')
will most probably not work as expected IF Sentinel RD uses the same
code as Sentinel Log Manager.

[SOLVED] Can't get PostgreSQL to start after following Wiki instruc...
I'm trying to start the postgresql service on my systemd installation. I've followed the instructions on the wiki. First I installed the package postgresql, then I uncommented the PGROOT line in the configuration file.
When I try to run systemctl start postgresql, I get the following:
# systemctl start postgresql
Job for postgresql.service failed. See 'systemctl status postgresql.service' and 'journalctl -n' for details.
# systemctl status postgresql

I tried doing what it suggested to me:

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

I also tried with the directory that was set in the configuration file, with similar results:
# su - postgres -c "initdb --locale en_US.UTF-8 -D '/var/lib/postgres'"
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
fixing permissions on existing directory /var/lib/postgres ... initdb: could not change permissions of directory "/var/lib/postgres": Operation not permitted
I don't know what to try next. I'm not sure what it needs me to do that it can't do itself. I've never worked with any kind of database system, I'm just installing PostgreSQL to start tinkering with it a bit for some pet projects.
Thanks for your time
Last edited by robrene (2012-10-28 13:24:52)Whelp, stupid me. Right after posting I managed to fix it myself. I'll post the solution and leave it here in case other people run into the same problem. The solution was to change the owner of the PGROOT directory and then running the initdb command again:
# chown -R postgres:postgres /var/lib/postgres/
# su - postgres -c "initdb --locale en_US.UTF-8 -D '/var/lib/postgres/data'" -
[SOLVED] upgrading postgresql from 9.0.4
I am trying to upgrade postgresql from 9.0.4 to 9.2.3 using the directions from the wiki (postgresql page, under "upgrading"), due to systemd causing my connections to be refused on my socket for 9.0.4...
# pacman -S postgresql-old-upgrade postgresql-libs
:: postgresql-libs is in IgnorePkg/IgnoreGroup. Install anyway? Y/n
resolving dependencies...
looking for inter-conflicts...
:: postgresql-libs and postgresql are in conflict (postgresql-client). Remove postgresql? y/N
If pacman wants to remove my old postgresql binaries, then how is pg_upgrade supposed to work when I need to feed it the location of the new binaries as well as the old ones?

Postgresql installed but not working due to missing socket
So I installed Postgresql onto my Mac and whenever I run anything like psql or createdb cool_database_name I get the following error.
psql: could not connect to server: No such file or directory Is the server running locally
and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
So I follow along the different solutions. I reinstall postgresql to no avail. I go to postgresql.conf` and change it to
#port = 5432 # (change requires restart)
#max_connections = 20 # (change requires restart)
# Note: Increasing max_connections costs ~400 bytes of shared memory per
# connection slot, plus lock space (see max_locks_per_transaction).
#superuser_reserved_connections = 3 # (change requires restart)
#unix_socket_directory = '/var/pgsql_socket' # (change requires restart)
#unix_socket_group = '' # (change requires restart)
#unix_socket_permissions = 0777 # begin with 0 to use octal notation
yet still nothing. I run commands such as
ls -lA /var/run/postgresql
Which tell me the file or directory does not exist.
I also check into the pg_hba.conf file but everything looks ok
# "local" is for Unix domain socket connections only local all all trust
# IPv4 local connections: host all all 127.0.0.1/32 trust
# IPv6 local connections: host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the # replication privilege.
#local replication jason trust
#host replication jason 127.0.0.1/32 trust
#host replication jason ::1/128 trust
When I run psql -h localhost I get
psql: could not connect to server: Connection refused Is the server running on host "localhost" (::1)
and accepting TCP/IP connections on port 5432?
could not connect to server:
Connection refused Is the server running on host "localhost" (127.0.0.1) and
accepting TCP/IP connections on port 5432?
could not connect to server:
Connection refused Is the server running on host "localhost" (fe80::1) and
accepting TCP/IP connections on port 5432?
I'm at a lost as to how to fix this. Any help would be appreciated.I see this all the time, even when AV is configured to exclude the RemoteInstall folder.
To work around it I do:
NET STOP WDSSERVER
DISM /UnMount-Wim /MountDir:"F:\RemoteInstall\SMSTempBootFiles\ZZZ00011" /Discard
DEL /f /s F:\RemoteInstall\SMSTempBootFiles\ZZZ00011\*.*
DISM /Mount-Wim /WimFile:"F:\RemoteInstall\SMSImages\ZZZ00011\bootimage.wim" /index:1 /MountDir:"F:\RemoteInstall\SMSTempBootFiles\ZZZ00011"
NET START WDSSERVER
Where ZZZ00011 is the package id of your boot image
This can be wrapped in a script for reuse
After net stop wdsserver the unmount command is failing:
Error DISM WIM Provider: PID=3892 TID=2220 base\ntsetup\opktools\dism\providers\wimprovider\dll\wimmanager.cpp:2796 - CWimManager::InternalOpUnmount(hr:0x80070032) -
I can not view tables or open the tables folder in Data Source Explorer when connected to a postgresql 9.2.4 database in Eclipse 4.4.2
I have set the driver to postgresql-9.2-1003.jdbc4.jar.
I can connect to the database, view the schema list, view the tables in pg_catalog but I can not view the tables in the public schema.
Thanks

I went back to using Netbeans. Every so often I attempt to use Eclipse as it does have some advantages over Netbeans but every time I do, I end abandoning it because something does not work.
