Error : Cannot export Display Linux

There are different tools to do X11 forwarding on Windows one of them Xming it's small software and very easy to use no need to do any special configuration only run the installation file.

But sometimes you are using this application and try to run the GUI on your desktop or laptop it's working like you excepted, one simple solution to solve it.

I am using as ssh client Putty, before put the server ip from putty left panel


  • Connection > SSH > X11
  • Check X11 forwarding: [x] Enable X11 forwarding
  • Add to the “X display location” field: localhost:0.0



Cheers

The following error appeared on application side while trying to deploy the new SRF on the application, as you see from the above error it's database error and to solve it follow the below steps :-



from database side :-

sqlplus /as sysdba

From the above picture check the index name and put it inside this query :-

select owner,index_name,table_name,status from dba_indexes where index_name='index_name';

OWNER    INDEX_NAME    TABLE_NAME    STATUS

ORA-00845: MEMORY_TARGET not supported on this system

Check the following Space :-

ECATSTDB oracle: :/home/oracle\>df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/Oracle-LogVol00
                       20G  3.3G   15G  18% /
/dev/mapper/Oracle-LogVol02
                       90G   45G   41G  53% /Oracle
/dev/sda1              99M   18M   77M  19% /boot
tmpfs                 3.0G     0  3.0G   0% /dev/shm


Increase the space

mount -t tmpfs shmfs -o size=6144m /dev/shm

now startup the database.
