For some reason the problem are not on application

These past few days, I got a lot of issue related with my company delivered product for enterprise applications. Few reasons that we got the issue complain direct to the application which because the applications not working as usual both in production and disaster recovery. Then I found few or problems that makes this happen

Wrong procedure when recover from disaster recovery (some part of Oracle engine corrupt)
Unproper rollback of Oracle XA driver on weblogic because of deleted some xa tables on Oracle
There's scheduler job that drop database users everyday, before restore some data.

Another issue that I can highlight was the capacity planning not monitored well, no of customer and activity increase without awareness of the operations, and now its overloaded.

Meanwhile, we usually hard to tell the customer that the problem is not on application side, but more in the operation procedures.

Blackberry Suspended in Indonesia

This past few weeks, a lot of news in media about mass suspended blackberry in Indonesia. Most of the people that had bought blackberry for last month years got a problem with the blackberry can't be used lately or what usually said was blackberry suspended which mean the blackberry can't be use for blackberry service anymore.

I had this experience before, either when the first time I bought blackberry 2 years ago. That time I bought 7290 at ITC Roxy Mas and unfortunately the blackberry that I bought was suspended, because the blackberry PIN still active on another service provider.

All blackberry devices has a pin as an identifier of uniqueness of the handset for the blackberry services. It's designed by the blackberry system from RIM that PIN will be unique on each handset and it will registered to the blackberry server to serve the customer such as forwarding email that we subscribe to the right handset. Blackberry handheld is re-present the client that will receive forwarding or any email or message that we registered to blackberry service system to provide us realtime email. And the blackberry server will automatically get and forward the email that arrive to our mailbox to the blackberry handheld device. That's why the blackberry PIN should be unique.

Last two week our government (Indonesia government) had a meeting with RIM and ask them to open the suspended PIN of blackberry so the customer is not got this suspended issue. But I don't know whether are they really understand what's make PIN is so important for RIM, and why they need to keep the PIN unique. In Indonesia there's now a heaven of blackberry seller, any blackberry handheld will be sold fast with better profit, but they event don't understand how this stuff works. (I mean most of them, not all). I just wonder how about if this thing happens, or one of the government guy had a PIN that duplicate by someone that not legally do it, and the effect some of the classified email or message send to wrong person, but that's the problem not because wrong destination address from the email or message, but because of the PIN duplicated, so the system don't know who's the owner.

I don't think RIM and all party want this thing happens, and for me, what RIM do to suspend the duplicate PIN was the right action if we consider the impact at the end.

From my point of view, if RIM just wanna make business they just allow all those handset active and don't care about duplication or in-secure system. But I really appreciate they still stand to maintain integrity and trust from their customers.

Menghadapi Hantu Pemakan Email (HPE) dengan FreeMem di BlackBerry

Saya akan share gimana untuk menghindari/mengurangi kemungkinan diatas.

Hantu pemakan email itu hidup kalau memory di blackberry oleh system dianggap kurang untuk melakukan proses.
Dengan tujuan mulia, email baru tetap akan bisa masuk, jadi kita bisa membaca latest email. Tidak seperti mailbox kalau penuh ya ngantri ampe kosong lagi.

Nah tapi secara penggunaan biasa yang agak abuse, klo gak salah denger org RIM aja bingung liat traffic Indo hehehe...
Inet mahal dikasih solusi murah bisa dibawa kemana2 ya gini deh

Tadi pagi ada yg posting memory habis ya? Coba clear cache, ato memory di bersihin

Solusi buat yg gak simple

Keep ur email under 5000 (untuk handset seri 87xx ke bawah)
Clear any chat history window after use. (YM, GTalk, BBM, JiveTalk, dsb)
Clear Browser History
Clear Log dr Home screen, ALT + LGLG > Menu > Clear Log
SoftReset seminggu sekali atau cabut battery. Untuk handset QWERTY bisa dengan menekan ALT + Caps + Del
FreeMem, sehari sekali. (Kaya makan obat aja) harus suruh yg buat benerin nih.

untuk solusi terakhir ini harus beli.
Kenapa pake FreeMem, bantu clean up memory tanpa perlu restart dalam waktu yang cukup singkat.
Cukup dijalankan sehari sekali jauh membantu.

FreeMem dapat diperoleh dengan harga Rp. 80.000,-

Untuk memperoleh FreeMem, email ke:

Order Freemem

Pembayaran mohon ditransfer ke rekening dibawah

Pertolongan Pertama Pada BlackBerry (P3BB)

Secara akhir-akhir ini banyak problem lagi dengan network untuk jaringan blackberry. Ada baiknya ini di share kembali. Jika anda mengalami idle tidak menerima email atau message or email tidak dapat terkirim, Anda dapat melakukan P3BB dengan langkah sebagai berikut:

1. Cabut batere minimal 1-2 menit
Fungsi ini sama seperti melakukan location update di handphone biasa,
yang kalau di jenis tersebut bisa hanya dengan turn of / turn on
lagi. Sayang nya BB harus dengan cara ini (CMIIW)

2. Registrasi HRT dari Options - Advanced Option - Host Registration
Table - (pencel lagi tombol opsi) - Register Now
Fungsi ini untuk memastikan HH anda terdaftar di network BlackBerry.
Dengan telah terdaftar, maka tunnel dari HH anda ke infrastruktur
BlackBerry sudah terbentuk. Tunnel link ini yang men-trigger capital
GPRS/EDGE/3G.

3. Send Service Book (SB)
Kalau sekira nya HH anda belum mendapatkan self registration email
dari BlackBerry, maka send SB hanya bisa di lakukan via pc / desktop.
Namun kalau sudah berhasil mendapatkan notifilasi self registration
namuan masih lower gprs/edge/3g, maka send SB bisa di lakukan dengan
masuk via email setting (browser: http://operator.blackberry.com)

Why developer not do testing?

Few days a go, in the middle of meeting, one of my staff told me, they still waiting for query that prepared by the System Analyst. Then it come out in my mind, why programmer can’t make their own SQL Query? If they don’t know how it was, then how they know the expect result from what they code.

Another team member also said, he delayed because can’t do real test in the development environment, and he got trouble to set connection with SIT database. So the question why did you need SIT database? And I really surprise with his answer, he said, he don’t know how to make the data to be available to test, and it means he don’t know how to use the applications.

From two of example in the morning meeting, I can figure out, why we can’t improve our software development speed and quality.

Developer not do testing based on the story because of

lack of business process
lack of understanding use the application they develop
requirements not detail enough
lazy to test
overconfidence of their skills

Be Honest

Yesterday I had been ask from my colleague to help them make presentation to one of our customers now. Our customers now in the process of merger of their bank, and a lot of things they need to be part of considerations, and which our product that have been implement to one of their business previously have possibility to be scrap. All the audience never involve in the projects before, since all is new staff after merger of the organizations.

Based on that situation, I just tried to be honest to explain what's our feature that we had delivered to them and what kind of advantages for them after that. And without any respect, I also tried to explain what of their expectation whether its possible to implement or not suggesting to implement, because it could be a problem and either not a applicable solutions. And from this discussion what I can get, our customer is more satisfied from the explanation, another things we build our confidence that we understand the business process and ready to work together with them for the best solutions we can provide.

In my industry specially IT, most people not try to "be honest" with their customers and most of it they talking or provide about all those thing that might be just a concept or nice to have things without look to the why they need these solutions. Move over sometimes they just say "yes" to the customer just to satisfied/convince the customer to buy product from them.
