Missing Grant Permissions for sys.v_$diag_alert_ext in grant_permissions.sql #207

Problem:

In alertlog.go

from v$diag_alert_ext

the application attempts to execute SELECT against SYS.V_$DIAG_ALERT_EXT.

However, the docker-compose/oracle/grant_permissions.sql script does not include the necessary GRANT SELECT statement for the pdbadmin user to access this view.

grant select on sys.aq$_queue_shards to pdbadmin;

This discrepancy results in three error occurrences upon docker-compose startup, as the application lacks the required permissions to query the view.
logger.Info("Failed to query the alert log three consecutive times, so will not try any more")

Steps to Reproduce:

  1. docker compose up
  2. Observe the application logs for errors related to querying SYS.V_$DIAG_ALERT_EXT.
observability-exporter  | time=2025-04-02T00:45:35.414Z level=INFO source=alertlog.go:40 msg="Log destination file does not exist, will try to create it: /log/alert.log"
observability-exporter  | time=2025-04-02T00:45:35.577Z level=ERROR source=alertlog.go:113 msg="Error querying the alert logs" !BADKEY="dpiStmt_execute: ORA-00942: table or view \"SYS\".\"V_$DIAG_ALERT_EXT\" does not exist"
observability-exporter  | time=2025-04-02T00:45:50.416Z level=ERROR source=alertlog.go:113 msg="Error querying the alert logs" !BADKEY="dpiStmt_execute: ORA-00942: table or view \"SYS\".\"V_$DIAG_ALERT_EXT\" does not exist"
observability-exporter  | time=2025-04-02T00:46:05.415Z level=ERROR source=alertlog.go:113 msg="Error querying the alert logs" !BADKEY="dpiStmt_execute: ORA-00942: table or view \"SYS\".\"V_$DIAG_ALERT_EXT\" does not exist"
observability-exporter  | time=2025-04-02T00:46:20.413Z level=INFO source=alertlog.go:29 msg="Failed to query the alert log three consecutive times, so will not try any more"

Expected Behavior:

The grant_permissions.sql script should include the following SQL statement to grant the pdbadmin user the necessary permissions:

grant select on sys.v_$diag_alert_ext TO pdbadmin;
