+## Symptoms  
+The current system is a coexistence system of 12c and 19c. The cluster is 19C, DBs are 19c+12c. The software is under different users: 19c (ORACLE user), 12c (oracle2 user).  
+Now, when running DBCA to create a database in the 12c environment, the following error is reported:  
+```
+DBT-00007 Users does not have the appropiate write privileges .  
+```
+Afterwards, the CRS Check reported the following error:  
+```
+PRVF-7595 : CRS status check cannot be performed on node "xxxx"
+PRVG-2043 : Command "/u01/app/19.7.0.0/grid/bin/crs_stat -t " failed on node "xxxx"
+```
+
+## Cause  
+```

+
+The CRS Check reported the following error:  
+```
+PRVF-7595 : CRS status check cannot be performed on node "node-b" - Cause: Could not verify the status of CRS on the node indicated using ''crsctl check''. - Action: Ensure the ability to communicate with the specified node. Make sure that Clusterware daemons are running using ''ps'' command. Make sure that the Clusterware stack is up.
+PRVG-2043 : Command "/u01/app/19.7.0.0/grid/bin/crs_stat -t " failed on node "node-b" and produced the following output: /u01/app/19.7.0.0/grid/bin/crs_stat.bin: error while loading shared libraries: libocr12.so: cannot open shared object file: No such file or directory - Cause: An executed command failed. - Action: Respond based on the failing command and the reported results.
+```
+The error during CRS CHECK indicates there is an incompatible command between the 12c DB and the 19c Grid.  
+
+## Solution  
+1. Check and ensure the CRS are truly running on all nodes .  
+2. Ignore this error if CRS is running fine on all nodes.  
+3. Continue to run installer.  
+Or you can use workaround:  
+$ export ORA_DISABLED_CVU_CHECKS=TASKCRSINTEGRITY,TASKNTP,STASKRESOLVCONFINTEGRITY  
+$ echo ORA_DISABLED_CVU_CHECKS  
+
+Reset the user and permissions for `/u01`.  
+Example:  
+```
+chown -R oracle2:oinstall /u01
+chmod -R 775 /u01
+```
