ORA-07265: sppst: semop error, unable to increment semaphore

官方解释

ORA-07265 is thrown when the shadow process slave process tries to update the semaphore and is unable to do so.

常见案例

This error occurs when there is an unexpected crash or shutdown of the database server, or when the system parameters is changed to a value that is not supported.

正常处理方法及步骤

1、 Ensure that the system parameters file (SPFILE or PFILE) being used is the correct one.

2、 Attempt to recreate the SPFILE or PFILE.

3、 Perform an OS level check on the semaphore values and adjust if necessary.

4、 Consider increasing the SHADOW_MAX_CONNECTions parameter.

5、 Increase the SEMMSL, SEMMNS, SEMOPM, and SEMMNI OS parameters, if necessary.

6、 Stop and restart the database instance. This should reset the semaphore values and make the application work.
