When Oracle dbstart/dbshut does not do anything

chmouel — Fri, 23 Apr 2010 10:06:24 +0000

If like me you are surprised by the fact that dbstart or dbshut does not do anything when launching it, just make sure to edit the /etc/oratab and have the last char as Y and not N. Like if it is like this :

orcl:/u01/app/oracle/product/11.2.0/dbhome_1:N

change it to this :

orcl:/u01/app/oracle/product/11.2.0/dbhome_1:Y

Import Export to different tablespace names with Oracle 9i

Renaming Oracle Database is a pain, coming from OpenSource DB like
MySQL or PostGres where we do that all the time i did not think that
Oracle have to be such a pain.

My only way i can find.

- If i have the tablespace named tablesp1 and owned by the
user user1, and i want to import it to another tablespace
called tablesp2 in an another Oracle 9i tablespace with the user
name user2.

I import the tablesp1 in an Oracle 10 (if you are lucky to have
one).
Make sure i create the user2 in the Oracle10 DB.
I connect as DBA access and i rename the tablespace with :
[code lang="sql"]
ALTER TABLESPACE tablesp1 RENAME TO tablesp2
ALTER TABLESPACE tablesp2 OWNER TO user2
[/code]
Export the Oracle10 tablespace with Oracle 9 exp.
Sometime sometime you may encounter that famous error
```
"EXP-00003 : no storage definition found for segment .....".
```
So you have have to
do this as well.
That’s it. The dump should be under tablespace name tablesp2 with
owner user2.

After installing Oracle instant client, if you have them in /usr/local/lib/instantclient_10_2, this is the command line i use :

./configure –with-instant-client=/usr/local/lib/instantclient_10_2 –with-oracle-includes=/usr/local/lib/instantclient_10_2/sdk/include –with-oracle-libraries=/usr/local/lib/instantclient_10_2 –with-oci-version=10G

Let me know ny email if you want the deb for ubuntu linux.

sqlplus timeout when connnecting

chmouel — Wed, 03 Jan 2007 02:24:26 +0000

If you are using a pam_ldap or pam_nis environement and it happend that sqlplus does not want to connect as user but it does as root, waiting for :

socket(PF_FILE, SOCK_STREAM, 0)         = 3
connect(3, {sa_family=AF_FILE, path="/var/run/.nscd_socket"}, 110) =
-1 ENOENT (No such file or directory)
close(3)                                = 0
open("/etc/hosts", O_RDONLY)            = 3
fcntl64(3, F_GETFD)                     = 0
fcntl64(3, F_SETFD, FD_CLOEXEC)         = 0
fstat64(3, {st_mode=S_IFREG|0644, st_size=286, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE
|MAP_ANONYMOUS, -1, 0) = 0x45b78000
read(3, "127.0.0.1tlocalhost.localdomaint"..., 4096) = 286
read(3, "", 4096)                       = 0
close(3)                                = 0
munmap(0x45b78000, 4096)                = 0
getpid()                                = 26002
getuid32()                              = 1121
futex(0x41239198, FUTEX_WAIT, 2, NULL

You just to have make sure to have nscd up and running. dunno what sqlplus does

Error loading native library: libnjni9.so

chmouel — Fri, 22 Dec 2006 00:29:57 +0000

If you like me when running oracle on x86_64 get that damn :

Error loading native library: libnjni9.so

when launching dbca and you have googled the thousands five hundred useless answer. Just add the path of the libs $ORACLE_HOME/lib and $ORACLE_HOME/lib32 to your /etc/ld.so.conf (or /etc/ld.so.conf.d/oracle.conf on RH derivative) and rerun ldconfig.

If this is during install just jump to a console after you add this line before it launching dbca and run a ldconfig -v as root.

Damn oracle….
