Errors in alert log and listener log and "alter database mount exclusive"

Question

Hello!
I need a help.
Database 11R2 works under MS Windows Server.
Whwn I start it using Services, according alert log it is started by command "alter database mount exclusive".
Next - alter database open.
After this, it seams that program, which should put data into database, can not work with it, because I see errors in alert log: ora-12537, 12560, 12535, 12570, 12547.
What does itmean and what to do?
This is extract from alert_log

Thank you.
But in the same time - when I see in alert log those error messages ora -12560, 12537,12535,12570 and so on - clients programs, whiie try to connect, hang up.
For sql plus takes 20 minutes to connect.

To tell the truth I am confuse - I thought I have only 1 service "XXXDB" and 1 instance - "xxx".
May be I have wrong entries in tnslsnr.ora?
