4. EXECUTIVE SUMMARY

It has been noticed that a system restart right after modifying some of the BSC databases cancause problems in the system. When adding the data to databases the system works the waythat first the information is saved to the memory and then after a short while copied todatabases of the Winchester disks.

5. DETAILED DESCRIPTION

If system is restarted before all the information is saved to disks, most probably the databaseswill be corrupted. Especially after the massive downloading of parameters from the Netact the

steps described in instructions section should be taken before giving a system restartcommand.

6. SOLUTION / INSTRUCTIONS

1. Before restarting the system the following checks should be done:

2. Make sure that fallback package is available in the BSC.

3. Copy the Databases to the disk:

ZDBC: BSDATA, 0;

ZDBC: OEDATA, 0;

ZDBC: EQUI PM, 0;ZDBC: I LDATA, 0;




ZDBC: PDDATA, 0;

4. Check the states of databases with commands:

ZDBS: BSDATA, 0;

ZDBS: OEDATA, 0;

ZDBS: EQUI PM, 0;

ZDBS: I LDATA, 0;

ZDBS: PDDATA, 0;

The states of databases have to be NORMAL.

5. Check the database consist both (W0 and W1) disks with command:

ZDBD: OMU;

6. Make sure that there is no disk updating in the queue

ZDUQ;

The values of SIMQUE and SEQQUE have to be zero (0).

7. NOTE

In the worst case if the system is restarted before all the information is saved to Winchesterdisks the only way to get BSC back to working is to activate the fallback package.

8. REFERENCE

None.
