• Try to find out the locked transaction id from the server error logs.
• Execute select * from dba_2pc_pending in DB console. You should be able to see the particular locked transaction Id under "local_tran_id" column, and "state" for this should be PREPARED in dba_2pc_pending table.
• Login to the database as sysdba. Execute the following command - sqlplus './as sysdba' rollback force "locked transaction id" Now if you will check dba_2pc_pending table again, the "state" should be changed to FORCED ROLLBACK for the transaction id.
• Now you should not get the above error any more. You can also execute commit force "locked transaction id" to avoid this error.

WORKING HARD: Macs don't work as well at work or at school.

If most of the computers in your office or school run Windows you may find it harder to get things done with a Mac.

Sharing documents and spreadsheets.

Giving presentations.

Protecting your drives.

SHARING: Macs don't like to share.

At least half the fun of having a computer is sharing the stuff that matters to you with other people. This is harder to do on a Mac.

Securely share your movies, music, and photos.

It's easy with a PC.

CHOICE: Macs don't let you choose.

PCs give you a lot more choice and capabilities for your money. You can get the PC you want, in the size and color you want, with the features you want. You just don't have as many options with a Mac.

Loaded with features.

Available in your favorite color.
