Oracle RAC error prkh-1010

When installing RAC, the system will prompt you to enter the dedicated node (host), public node (public), virtual node (vip)-These nodes are all set in the system etc file. the public node is used for external or internal personnel to view data. dedicated Network is used for Oracle internal communication (management ). the virtual node is used when the master node oracle database or database system cannot be used, oracle will automatically switch to its corresponding virtual node. for example

When node A's database or database system cannot be used, oracle will automatically switch to slave node. if the slave node is damaged, the business received by node A is switched to Node B. then you start crs at node A, that is, the system will prompt the prkh-1010. in this case, you need to use the vipca command to repair the VIP node. of course, you can also use crs_start-all-q to start some functions.
