Masalah upgrade
Saat Anda mengupgrade CLI mcdc ke versi terbaru, CLI tersebut
akan melakukan upgrade skema database internal yang secara otomatis membuat
pencadangan data yang dikumpulkan dan dinilai oleh versi sebelumnya.
Dalam kasus yang jarang terjadi, upgrade CLI mcdc tidak berhasil
selesai karena kegagalan dalam mengupgrade database lokal. Hal ini dapat terjadi
karena kerusakan selama upgrade database yang merusak database,
sehingga data yang dikumpulkan sebelumnya akan hilang.
Setelah mengupgrade CLI mcdc, saat menjalankan versi terbaru, jika Anda melihat error yang menunjukkan bahwa upgrade database gagal, Anda dapat menggunakan perintah recover-db untuk memulihkan database ke versi yang berfungsi sebelumnya, lalu melakukan downgrade ke versi CLI mcdc sebelumnya.
Lakukan langkah-langkah berikut:
Pulihkan database ke versi kerja sebelumnya:
./mcdcdiscoverrecover-db
Download
versi mcdc CLI yang Anda gunakan sebelum upgrade.
Saat menginstal mcdc CLI versi lama, jangan
hapus direktori mcdc CLI yang dibuat oleh
versi saat ini.
